It is a kind of to be used for medical treatment detection pcb board used and preparation method thereofTechnical field
It is particularly a kind of to be used for medical treatment detection pcb board used and preparation method thereof the present invention relates to pcb board field.
Background technology
Pcb board, is called printed circuit board or printed circuit board (PCB), is a kind of supplier of electronic component electrical connection, PCBThe major advantage of plate is the mistake for greatly reducing wiring and assembling, improves the gentle productive labor rate of Automated water.Object of reference1, existing pcb board is typically disposed with solder mask, copper plate and basic unit from top to bottom, can only meet pcb board in ordinary linesThe application of road-load body, it is impossible to be used in medical detection field, application is narrower.
The content of the invention
It is contemplated that at least solving one of above-mentioned technical problem in correlation technique to a certain extent, there is provided a kind of energyIt is enough in medical treatment detection pcb board used and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is：
It is a kind of to be used to be provided with carbon nanotube coating in medical treatment detection pcb board used, including basic unit, the basic unit, instituteState and solder mask is provided with carbon nanotube coating, the solder mask is provided with to place the window of thing to be detected, and the carbon is receivedMitron coating is additionally provided with pin.
Further, the solder mask is arranged between the electrode of CNT two.
Further, the pin is drawn with silver paste silk.
Further, the basic unit is FR4 epoxy resin layers.
Further, the basic unit is ceramic substrate.
The present invention also provides a kind of method for making above-mentioned pcb board, comprises the steps of：
A. the copper in basic unit is removed；
B. the pin of CNT is drawn with silver paste silk；
C. CNT is printed on the pcb board；
D. solder mask is stamped between the electrode of CNT two；
E. clean.
Further, the copper is understood on etching machine by etching solution.
Further, the CNT is printed on pcb board by the way of silk-screen.
Further, the solder mask is printed on the CNT by the way of silk-screen.
Further, cleaned by the way of plasma cleaning.
The beneficial effects of the invention are as follows：The present invention provides a kind of pcb board used for medical treatment detection, utilizes CNTIt can launch the characteristic of fluorescence under laser irradiation, CNT is arranged in basic unit, available for medical field trace proteinDetection；The present invention also provides a kind of method for making above-mentioned pcb board, and step is terse, on the premise of it can meet technological requirement,Accomplish efficiency maximization, minimization of cost.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of pcb board of the prior art；
Fig. 2 is the structural representation of the pcb board of the present invention.
Embodiment
Reference picture 2, it is of the invention it is a kind of be used for medical treatment detection pcb board used, be disposed with from bottom to up basic unit 1,Carbon nanotube coating 2 and solder mask 3, the solder mask 3 are provided with to place the window 5 of thing to be detected, the CNTCoating 2 is provided with pin 4, and the pin 4 is used to be connected with external analysis equipment, detection information is exported to analytical equipment,In the present embodiment, the pin 4 is drawn to connect external analysis equipment with silver paste silk.In use, thing to be detected is passed through into instituteState window 5 to be placed directly on CNT, then be irradiated with laser the region, protein can be hindered the laserGear, pin 4 can export the real time emission situation of fluorescence in form of electricity to outside analytical equipment, so as to learn the egg of detectionThe situation of change of white matter molecule.Main irradiated using CNT with laser of the invention can launch the characteristic of fluorescence to be examinedSurvey.
Further, the solder mask 3 is arranged between the electrode of CNT two, prevents two electrodes to be connected shortRoad.
Further, the basic unit 1 is FR4 epoxy resin layers or ceramic substrate 1, and this is two kinds of preferred materials of the present inventionMaterial, in other embodiments, also can be using other basic units 1 material.
The present invention also provides a kind of method for making above-mentioned pcb board, comprises the following steps：
A. the copper in basic unit 1 is removed, it is preferred that removal is etched to the copper in basic unit 1 using etching machine, removedCheng Zhong, adds corresponding etching solution, such as copper etchant solution；
B. the pin 4 of CNT is drawn with silver paste silk, to be connected with outside analytical equipment；
C. CNT is printed on the pcb board, it is preferred that be printed on CNT by the way of silk-screen describedOn pcb board, in other embodiments, it can also be substituted by the way of spraying；
D. solder mask 3 is stamped between the electrode of CNT two, prevents two electrodes from connecting, it is preferred that using the side of silk-screenSolder mask 3 is printed between two electrodes of CNT by formula；
E. clean, it is preferred that by the way of the cleaning of plasma dustiness, can targetedly complete the cleaning to pcb board.
Above concrete structure and sized data are that presently preferred embodiments of the present invention is illustrated, but present invention woundMake and be not limited to the embodiment, those skilled in the art can also make kind on the premise of without prejudice to spirit of the inventionThe equivalent variations planted or replacement, these equivalent deformations or replacement are all contained in the application claim limited range.
