導線架料片Lead frame blank

本發明涉及一種導線架相關的產品，尤指一種能消除應力的導線架。The invention relates to a lead frame related product, in particular to a lead frame capable of eliminating stress.

按，半導體元件在發揮其功能前，必須安裝於一導線架 (Lead Frame) 上並相互電連接，以進行封裝。According to the key, semiconductor components must be mounted on a lead frame (Lead Frame) and electrically connected to each other for packaging before performing their functions.

其中，所述導線架係透過模組化大量製造的方式進行生產，藉以因應不同半導體元件所需的引腳形態，如圖10所示，現有一種導線架料片70，其係包括有兩軌道(rail)71以及複數個導線架單元72，其中該複數個導線架單元72排列於該兩軌道71之間，各導線架單元72呈一薄片狀、具有一大面積的壓薄(coin)區域721，供安裝半導體晶片，且各導線架單元72與相鄰的導線架單元72或軌道71透過一連接桿722相連接，在製造的過程中，該兩軌道71提供一定位的效果，使現有導線架料片70能定位於一模具上，藉以透過沖壓的方式形成該複數個壓薄區域721。Wherein, the lead frame is produced through modular mass manufacturing, so as to meet the pin shapes required by different semiconductor devices. As shown in FIG. 10, there is alead frame material 70 that includes two tracks. (rail) 71 and a plurality oflead frame units 72, wherein the plurality oflead frame units 72 are arranged between the tworails 71, and eachlead frame unit 72 is in the shape of a sheet with a large area ofcoin area 721, for mounting semiconductor chips, and eachlead frame unit 72 is connected to the adjacentlead frame unit 72 orrail 71 through a connectingrod 722. During the manufacturing process, the tworails 71 provide a positioning effect, making the existing Thelead frame material 70 can be positioned on a mold, thereby forming the plurality ofthinned regions 721 by stamping.

然而，為了確保該導線架料片70的結構強度，各該連接桿722需具有一寬度T₀，如此一來，由於各該連接桿722的剛性大、不易釋放應力，使壓薄成形的過程中產生的應力會在各該導線架單元72直接傳遞，進而導致現有導線架料片70在完成加工之後會產生大幅度的尺寸偏差。However, in order to ensure the structural strength of thelead frame material 70, each of the connectingrods 722 needs to have a width T_0. As a result, due to the large rigidity of each of the connectingrods 722, it is not easy to release the stress. The stress generated in thelead frame unit 72 will be directly transmitted, which will cause the existing lead frame blank 70 to have a large size deviation after processing.

如圖10及圖10A所示，現有導線架料片70經過壓薄成形之後，會產生0.0203公釐(mm)的長度方向延展量L₀，以及產生0.0729公釐的寬度方向延展量W₀，使該複數個導線架單元72經加工之後產生較大的尺寸偏差，增加後續封裝製程定位的困難。As shown in FIGS. 10 and 10A, after the conventionallead frame material 70 is thinned and formed, a lengthwise extension L_{0 of} 0.0203 mm (mm) and a widthwise extension W_{0 of} 0.0729 mm will be generated. After the plurality oflead frame units 72 are processed, a larger size deviation occurs, which increases the difficulty of positioning in the subsequent packaging process.

為解決現有導線架料片的連接桿剛性大、不易釋放應力，導致現有導線架料片在完成壓薄加工之後會產生較大的尺寸偏差的問題，本發明提供一種能消除應力的導線架料片，有效改進上述問題，進一步說明如下。In order to solve the problem that the connecting rod of the existing lead frame material is rigid and difficult to release stress, which causes the existing lead frame material to have a large size deviation after the thinning process is completed, the present invention provides a lead frame material that can eliminate stress To effectively improve the above problems, further explanation is as follows.

本發明係一種導線架料片，其係具有一第一方向，該導線架料片包括有： 兩軌道，沿著該第一方向呈平行設置； 複數個重複單元，沿著該第一方向排列於該兩軌道之間，各該重複單元包括至少一主體區，各該主體區與各該軌道之間定義為一第一連接位置，且相鄰兩個該主體區之間定義為一第二連接位置； 複數個連桿，各該連桿設於該等第一連接位置及該等第二連接位置的其中一連接位置上，且該等連桿呈間隔設置，各該連桿由相對應主體區的外周緣凸伸而出，且各該連桿具有一軸線、兩連接臂及一位於該兩連接臂之間的穿孔，該軸線與該外周緣相交，該兩連接臂係位於該軸線的兩側，且各該連接臂的至少一部分以與該軸線呈非平行的方向延伸；以及 複數個壓薄區域，各該壓薄區域係凹設於其中一主體區或其中一連接臂上。The present invention is a lead frame material piece, which has a first direction, and the lead frame material piece includes: Two rails are arranged in parallel along the first direction; A plurality of repeating units are arranged between the two tracks along the first direction, each repeating unit includes at least one main body area, and a first connection position is defined between each main body area and each track and is adjacent A second connection position is defined between two main areas; A plurality of connecting rods, each of the connecting rods is set at one of the first connecting positions and the second connecting positions, and the connecting rods are arranged at intervals, and each connecting rod is defined by the corresponding main body area The outer peripheral edge protrudes, and each of the connecting rods has an axis, two connecting arms and a through hole located between the two connecting arms, the axis intersects the outer peripheral edge, and the two connecting arms are located on both sides of the axis , And at least a part of each of the connecting arms extends in a direction non-parallel to the axis; and A plurality of thinning areas, each thinning area is recessed on one of the main body areas or one of the connecting arms.

藉由上述的技術特徵，本發明透過各該連桿的穿孔、兩斜向延伸的連接臂的結構有效提升材料於沖壓加工時的應變能力並消除材料延展應力，因此，在各該主體區上沖壓大面積的壓薄區域，或是在各該連接臂上沖壓所述壓薄區域時，在壓薄成形(沖壓)的過程中所產生應力，能在通過該兩連接臂的過程被加以釋放，有效避免應力傳遞到相鄰的軌道或主體區上，進而可有效解決該導線架料片延展過度、尺寸偏差過大的問題，故本發明有效改進現有導線架料片的連接桿剛性大、不易釋放應力所產生的缺點，藉以提供一種能消除應力的導線架料片。With the above technical features, the present invention effectively improves the strain capacity of the material during stamping and eliminates the ductile stress of the material through the perforation of each connecting rod and the structure of two connecting arms extending diagonally. When punching a large-area thinned area, or punching the thinned area on each of the connecting arms, the stress generated during the thinning forming (punching) process can be released during the process of passing through the two connecting arms , It can effectively prevent the stress from being transmitted to the adjacent track or the main body area, and can effectively solve the problem of excessive extension and excessive size deviation of the lead frame material. Therefore, the present invention effectively improves the existing lead frame material. The connecting rod is rigid and difficult. It relieves the shortcomings caused by the stress, thereby providing a lead frame material that can eliminate the stress.

Non-parallel, and further, eachparallel section 313 is connected to therail 11 connected by the connectingrod 30.

在本發明的第一較佳實施例中，如圖2及圖3所示，各該壓薄區域40係凹設於其中一主體區21上，使各該主體區21可便於固晶。In the first preferred embodiment of the present invention, as shown in FIGS. 2 and 3, each of thethinned regions 40 is recessed on one of themain regions 21, so that each of themain regions 21 can be easily bonded.

藉由該兩連接臂31的設置，當本發明第一較佳實施例的導線架料片10進行沖壓時，以各該主體區21上的壓薄區域40為中心向外傳遞的應力會沿著該連桿30的兩連接臂31朝不同方向產生應變，使沖壓所產生的應力可容易釋放，減少材料的延展應力，並降低應力沿著該連桿30傳遞至該鄰接的主體區21或是軌道11的情況；又，該等連桿30係呈間隔設置而不相連，故可促進應力釋放；進一步，由於各該連接臂31於該轉折部311的位置具有較弱的結構強度，有助於應力傳遞至該轉折部311時，該連接臂31產生變形，藉此促進釋放應力的效果；較佳的是，由於該凸部33凸設於該主體區21的外周緣，此形狀能引導該主體區21的材料受沖壓時朝該軸線A的方向往該穿孔32延展，降低應力往該穿孔32以外的部位傳遞，藉以提高該連桿30對該主體區21釋放應力的效果。With the arrangement of the two connectingarms 31, when the lead frame blank 10 of the first preferred embodiment of the present invention is punched, the stress transferred outwards with thethinned area 40 on themain body region 21 as the center The two connectingarms 31 of the connectingrod 30 generate strains in different directions, so that the stress generated by stamping can be easily released, reducing the ductile stress of the material, and reducing the stress transmission along the connectingrod 30 to the adjacentmain body region 21 or This is the case of thetrack 11; in addition, the connectingrods 30 are arranged at intervals and not connected, which can promote stress release; further, since each of the connectingarms 31 has a weaker structural strength at the position of theturning portion 311, When the stress is transferred to theturning portion 311, the connectingarm 31 is deformed, thereby promoting the effect of stress relief; preferably, since theconvex portion 33 is protruding from the outer periphery of themain body region 21, this shape can The material guiding themain body region 21 extends toward theperforation 32 in the direction of the axis A when being punched, so as to reduce the transmission of stress to parts other than theperforation 32, thereby improving the effect of the connectingrod 30 to release the stress on themain body region 21.

例如，如圖2及圖2A所示，與如圖10及圖10A所示的現有導線架料片70相比，在其他變因條件相同的情況下，本發明所提供的導線架料片10經過壓薄成形之後，僅會於第一方向L上產生0.0034公釐(mm)的長度方向延展量L₁，以及於第二方向W上產生0.0397公釐的寬度方向延展量W₁，換句話說，本發明的導線架料片10經壓薄成形之後會產生的尺寸偏差遠小於現有導線架料片，在長度方向的展延量，本發明的導線架料片10比現有導線架料片減少了83%，在寬度方向的展延量，本發明的導線架料片10比現有導線架料片減少了46%，因此本發明的導線架料片10具有較小的尺寸偏差量，大幅改善現有導線架料片70沖壓後過度延展的問題。For example, as shown in FIG. 2 and FIG. 2A, compared with the conventionallead frame material 70 shown in FIG. 10 and FIG. 10A, thelead frame material 10 provided by the present invention is the same when other variable conditions are the same. After thinning and forming, only a lengthwise extension L_{1 of} 0.0034 mm (mm) in the first direction L will be produced, and a widthwise extension W_{1 of} 0.0397 mm in the second direction W, in other words In other words, the size deviation of thelead frame material 10 of the present invention after being thinned and formed is much smaller than that of the existing lead frame material, and the amount of extension in the length direction is greater than that of the existing lead frame material. Reduced by 83% in the width direction, thelead frame material 10 of the present invention is 46% less than the existing lead frame material. Therefore, thelead frame material 10 of the present invention has a smaller dimensional deviation and a large amount of The problem of excessive extension of the existinglead frame material 70 after stamping is improved.

其中，在導線架料片10的製程或封裝廠的製程中，由於為了將該導線架料片10定位，該兩軌道11分別貫穿設有複數個定位孔111。Wherein, in the manufacturing process of the lead frame blank 10 or the manufacturing process of the packaging factory, in order to position the lead frame blank 10, a plurality ofpositioning holes 111 are respectively penetrated by the tworails 11.

如圖4所示，本發明第二較佳實施例的結構與與第一較佳實施例相近似，其與第一較佳實施例的差異在於：該導線架料片10於該重複單元20中，至少一組相鄰的兩主體區21之間設有一所述連桿30A，藉以連接該兩主體區21 (即該連桿30A設於第二連接位置212)，其中該連桿30A的各連接臂31的兩端分別連接該兩主體區21，且各該連接臂31具有一轉折部311及兩夾角段312，該兩夾角段312形成於該轉折部311的兩側，各該夾角段312與另一連接臂31的其中一夾角段312相對於該軸線A呈等夾角φ地設置，使該兩連接臂31略呈一菱形，即各該連接臂31所有部分均與該軸線A呈非平行設置，且該連桿30A具有兩凸部33，該兩凸部33係沿著該軸線A分別凸設於該兩主體區21的外周緣，並分別伸入該兩連接臂31之間形成的空間，即該穿孔32，藉以引導該兩主體區21受沖壓時朝該連桿30A的方向延展。As shown in FIG. 4, the structure of the second preferred embodiment of the present invention is similar to that of the first preferred embodiment, and the difference from the first preferred embodiment is that thelead frame material 10 is in the repeatingunit 20 At least one set of the connectingrod 30A is provided between twoadjacent body regions 21 to connect the two body regions 21 (that is, the connectingrod 30A is set at the second connecting position 212), wherein the connectingrod 30A Both ends of each connectingarm 31 are respectively connected to the twomain body regions 21, and each connectingarm 31 has a turningportion 311 and twoangled sections 312. The twoangled sections 312 are formed on both sides of theturning portion 311, and each of the angles Thesection 312 and one of theangle sections 312 of the other connectingarm 31 are arranged at an equal included angle φ with respect to the axis A, so that the two connectingarms 31 are slightly diamond-shaped, that is, all parts of each connectingarm 31 are aligned with the axis A. It is arranged non-parallel, and the connectingrod 30A has twoconvex portions 33 which are respectively protruded on the outer peripheries of the twomain body regions 21 along the axis A, and respectively extend into the two connectingarms 31 The space formed therebetween, namely theperforation 32, guides the twomain body regions 21 to extend in the direction of the connectingrod 30A when they are punched.

進一步，各該壓薄區域40呈一矩形，而具有兩對兩相對的邊，該壓薄區域40位於相對應主體區21的中央處，且該壓薄區域40的其中一對兩相對的邊與該第二方向W及該連桿30A的軸線A相平行，且該兩連接臂31相距最遠部位分別位於對應該壓薄區域40的該兩相對的邊的延伸方向上，舉例來說，如圖4及圖4A所示，在本發明的第二較佳實施例中，該連桿30A的各連接臂31的轉折部311為距離另一連接臂31最遠的部位，且各該連接臂31的轉折部311位於該壓薄區域40與該軸線A相平行的該兩相對的邊的延伸方向上，藉由該兩連接臂31之間的最大間距與該壓薄區域40的寬度約相等的技術特徵，能促進引導該壓薄區域40的壓力進行釋放，且此效果對於設於所述第一連接位置211的連桿30亦能適用。Further, each of thethinning areas 40 is a rectangle with two pairs of opposite sides, thethinning area 40 is located at the center of the correspondingmain body region 21, and one of the two opposite sides of thethinning area 40 It is parallel to the second direction W and the axis A of the connectingrod 30A, and the farthest parts of the two connectingarms 31 are respectively located in the extending directions of the two opposite sides corresponding to thethinned area 40. For example, As shown in FIGS. 4 and 4A, in the second preferred embodiment of the present invention, theturning portion 311 of each connectingarm 31 of the connectingrod 30A is the position farthest from the other connectingarm 31, and each connectingarm 31 Theturning portion 311 of thearm 31 is located in the extending direction of the two opposite sides parallel to the axis A of thethinned area 40, and the maximum distance between the two connectingarms 31 is approximately equal to the width of thethinned area 40 The same technical features can promote the release of the pressure in thethinned area 40, and this effect can also be applied to the connectingrod 30 provided at thefirst connection position 211.

在其他可能的實施態樣中，連接相鄰兩主體區21的連桿30A的各該連接臂31相對於該轉折部311的兩側也可以是一夾角段312及一平行段313，藉以形成如第一較佳實施例設於各該主體區21與相鄰對應軌道11的連桿30的形狀；此外，亦可沿著該第一方向L排列的相鄰兩主體區21之間設置該連桿30A。In other possible implementations, each of the connectingarms 31 of the connectingrods 30A connecting twoadjacent body regions 21 relative to the two sides of theturning portion 311 may also be an includedangle section 312 and aparallel section 313, thereby forming For example, in the first preferred embodiment, it is set in the shape of each of themain body regions 21 and the connectingrods 30 of the adjacentcorresponding rails 11; in addition, thebody regions 21 may also be arranged between twoadjacent body regions 21 arranged along the first direction L Connectingrod 30A.

根據上述內容，本發明的導線架料片10的各該重複單元20的主體區21透過該至少一連桿30、30A連接一鄰接件，該鄰接件可為如圖4所示為另一主體區21或如圖2所示為所述軌道11，藉以使各主體區21內部的應力容易釋放，且降低各主體區21內部的應力傳遞至鄰接件上的情形，即降低應力傳遞至相鄰的主體區21或軌道11，藉以避免材料過度延展；此外，各該重複單元20亦能具有複數個所述連桿30、30A，而透過該複數個連桿30、30A連接複數個鄰接件，例如：兩主體區21、兩軌道11，或一主體區21及一軌道11等。又，為進一步兼顧消除應力及導線架料片10的結構強度，本發明係可如第一較佳實施例，僅於該等第一連接位置211配置具穿孔32的連桿30。Based on the foregoing, themain body region 21 of each repeatingunit 20 of thelead frame material 10 of the present invention is connected to an abutting member through the at least one connectingrod 30, 30A. The abutting member may be another body as shown in FIG. 4Area 21 or as shown in FIG. 2 is thetrack 11, so that the stress inside eachmain body area 21 is easily released, and the stress transfer inside eachmain body area 21 to the adjacent parts is reduced, that is, the stress transfer to the adjacent parts is reduced. Themain body area 21 or thetrack 11 of, in order to avoid the material from excessively extending; in addition, each repeatingunit 20 can also have a plurality of the connectingrods 30, 30A, and a plurality of adjacent parts are connected through the plurality of connectingrods 30, 30A, For example: twomain areas 21, twotracks 11, or onemain area 21 and onetrack 11, etc. In addition, in order to further balance the stress relief and the structural strength of thelead frame material 10, the present invention can, as in the first preferred embodiment, only be provided with the connectingrods 30 withperforations 32 at thefirst connection positions 211.

進一步，本發明第三較佳實施例與第一較佳實施例的差異在於：在本發明第三較佳實施例中，如圖5所示，該兩連接臂31分別為一斜直桿，使該穿孔32呈一三角形，由於該兩連接臂31與該軸線A之間具有夾角φ的斜向設置，即各該連接臂31之整體與該軸線A呈非平行設置，因此，應力傳遞至該兩連接臂31會造成該兩連接臂31的應變，藉以釋放應力，避免應力集中傳遞到鄰接件 (即相鄰的軌道11或主體區21) 上。Furthermore, the difference between the third preferred embodiment of the present invention and the first preferred embodiment is that: in the third preferred embodiment of the present invention, as shown in FIG. 5, the two connectingarms 31 are respectively an inclined straight rod. Theperforation 32 is made into a triangle. Since the two connectingarms 31 and the axis A are arranged obliquely with an included angle φ, that is, the entire connectingarms 31 are arranged non-parallel to the axis A, and therefore, the stress is transmitted to The two connectingarms 31 will cause strain on the two connectingarms 31, so as to release the stress and prevent the stress concentration from being transferred to the adjacent member (ie, theadjacent rail 11 or the main body region 21).

如圖6所示，本發明第四較佳實施例與第一較佳實施例的差異在於：設於該第一連接位置的各該連桿30的兩連接臂31的夾角段312連接該連桿30所連接的軌道11，該兩連接臂31的平行段313連接該連桿30所連接的主體區21，即該兩平行段313自該主體區21朝相鄰對應的軌道11平行延伸，再以等夾角φ地各自朝遠離該軸線A的方向漸擴延伸，形成所述轉折部311及夾角段312，該兩夾角段312與該相鄰對應的軌道11相連接。As shown in FIG. 6, the difference between the fourth preferred embodiment of the present invention and the first preferred embodiment is that theangle section 312 of the two connectingarms 31 of eachlink 30 disposed at the first connecting position connects the connectingrod 30 Therail 11 connected by therod 30, theparallel sections 313 of the two connectingarms 31 connect themain body area 21 connected by the connectingrod 30, that is, the twoparallel sections 313 extend in parallel from themain body area 21 toward the adjacentcorresponding rail 11, Then each gradually expands and extends away from the axis A at an equal included angle φ to form theturning portion 311 and the includedangle section 312, and the two includedangle sections 312 are connected to the adjacentcorresponding rail 11.

請參閱如圖7至圖9所示，本發明第五較佳實施例與第一較佳實施例的主要差異在於：所述複數個壓薄區域40係凹設於該複數個連桿30、30A的連接臂31上靠近所連接主體區21的位置，各該連接臂31具有一轉折部311及兩夾角段312，且各該連接臂31上設有所述壓薄區域40的位置之寬度大於該連接臂31遠離所連接主體區21位置之寬度，使該連接臂31呈不等寬，且遠離所連接主體區21之部分較細，當該導線架料片10進行沖壓時，以各該連接臂31上的壓薄區域40為中心向外傳遞的應力會沿著該連接臂31傳遞並產生應變，由於各該連接臂31斜向延伸且具所述轉折部311，因此容易變形，讓沖壓所產生的應力容易於該連接臂31上釋放，減少材料的延展應力，並降低應力沿著該連桿30傳遞至該鄰接的主體區21或是軌道11的情況，其中各該連接臂31具有較細之部位，可促進應力之釋放。Please refer to FIGS. 7-9. The main difference between the fifth preferred embodiment of the present invention and the first preferred embodiment is that the plurality of thinningregions 40 are recessed in the plurality of connectingrods 30, The connectingarm 31 of 30A is at a position close to the connectedbody area 21, each connectingarm 31 has aturning portion 311 and twoangled sections 312, and each connectingarm 31 is provided with the width of thethinned area 40 It is larger than the width of the connectingarm 31 far away from the connectedmain body area 21, so that the connectingarm 31 is of unequal width, and the part away from the connectedmain body area 21 is thinner. When the lead frame blank 10 is punched, each The stress transferred outward from thethinned area 40 on the connectingarm 31 will be transmitted along the connectingarm 31 and produce strain. Since each connectingarm 31 extends diagonally and has theturning portion 311, it is easy to deform. The stress generated by stamping can be easily released on the connectingarm 31, reducing the elongation stress of the material, and reducing the transmission of stress along the connectingrod 30 to the adjacentmain body region 21 or therail 11, wherein each connectingarm 31 has a thinner part, which can promote the release of stress.

再進一步，如圖2及圖3的第一實施例或圖7至圖9的第五實施例所示，為避免應力傳遞至該導線架料片10的定位孔111而造成該定位孔111變形，設於第一連接位置211的連桿30適合應用第一較佳實施例中的連桿30形狀，即各該連桿30與所連接軌道11係以各該連接臂31的平行段313相連接，且各該連桿30的軸線A通過其中一定位孔111的中心，該兩平行段313延伸的方向從該定位孔111的兩側通過，而不通過該定位孔111；或者如第五較佳實施例中的連桿30、30A形狀，即各該連接臂31遠離主體區21的夾角段312之延伸線亦不會通過該定位孔111。Furthermore, as shown in the first embodiment of FIGS. 2 and 3 or the fifth embodiment of FIGS. 7-9, thepositioning hole 111 is deformed in order to prevent stress from being transmitted to thepositioning hole 111 of thelead frame material 10 , The connectingrod 30 set at the first connectingposition 211 is suitable for applying the shape of the connectingrod 30 in the first preferred embodiment, that is, each connectingrod 30 and the connectedrail 11 are connected by theparallel section 313 of each connectingarm 31. Connected, and the axis A of each connectingrod 30 passes through the center of one of thepositioning holes 111, and the extending direction of the twoparallel sections 313 passes through both sides of thepositioning hole 111 instead of thepositioning hole 111; or The shape of the connectingrods 30 and 30A in the preferred embodiment, that is, the extension line of theangle section 312 of each connectingarm 31 away from themain body region 21 will not pass through thepositioning hole 111.

藉由上述的技術特徵，本發明透過間隔配置的各該連桿30、30A的穿孔32、兩斜向延伸的連接臂31的結構有效提升材料於沖壓加工時的應變能力並消除材料延展應力，因此，當各該主體區21上具有大面積的壓薄區域40，或是各該連接臂31上具有所述壓薄區域40時，在壓薄成形(沖壓)的過程中所產生應力，能在通過該兩連接臂31的過程被加以釋放，有效避免應力傳遞到相鄰的軌道11或主體區21上，進而可有效解決該導線架料片10延展過度、尺寸偏差過大的問題，故本發明有效改進現有導線架料片的連接桿剛性大、不易釋放應力所產生的缺點，藉以提供一種能消除應力的導線架料片。With the above technical features, the present invention can effectively improve the strain capacity of the material during stamping and eliminate the ductile stress of the material through the structure of theperforation 32 of each of the connectingrods 30 and 30A and the two obliquely extending connectingarms 31 arranged at intervals. Therefore, when each of themain body regions 21 has a large-area thinning area 40, or each of the connectingarms 31 has thethinning area 40, the stress generated during the thinning (pressing) process can be The process of passing through the two connectingarms 31 is released, which effectively avoids the transmission of stress to theadjacent rail 11 or themain body area 21, and can effectively solve the problem of excessive extension and excessive size deviation of thelead frame material 10 The invention effectively improves the disadvantages that the connecting rod of the existing lead frame material is rigid and difficult to release stress, so as to provide a lead frame material that can eliminate stress.
