Description
Technical field
The present invention relates to a kind of production methods of the electrical measurement plate for electric performance test, more particularly to a kind of LCD that is used for produce
The production method of the electrical measurement plate of product electric performance test.
Background technology
The company of the liquid crystal displays such as production LCD will do its electrical property after the completion of product corresponding test at present, have
Body method is to connect product with electric logging device, product be powered after picture can be shown, people by picture show situation come
Judge the performance of product, whether typically response time, picture be complete and clear etc..From the development of new product to production process
And final all links of shipment are required for carrying out electrical property detection to product, it is therefore desirable to make corresponding electrical measurement plate, pass through
Electrical measurement plate links together product and electric logging device, achievees the purpose that the display that is powered.
And in existing electrical measurement plate manufacture craft, because the method used is incomplete, and so that electrical measurement plate can not be by
It must rapidly and efficiently make.
The content of present invention
The object of the present invention is to provide a kind of production methods of the electrical measurement plate for electric performance test, solve existing electrical measurement plate
Production method cannot quickly, efficient the problem of producing electrical measurement plate.
The technical solution adopted by the present invention to solve the technical problems is：A kind of system of electrical measurement plate for electric performance test
Make method, includes the following steps：
Step 1：The pcb board that will be covered with layers of copper smears one layer of photoresists, and thickness is 20~30um；
Step 2：The film panel assembly for arranging circuit is placed on exposure sources, then by the pcb board Jing Guo step 1
Immediately below film plate；Then exposure machine is opened, irradiates film plate with UV light, irradiation time is 80~90S, intensity of illumination 60~90
Milliwatt/square centimeter, once irradiating molding；
Step 3：It is 10g the ratio by step 2 treated pcb board is placed on sodium hydroxide and water：1000g's is low
Corrode in sodium hydroxide solution, when corrosion a length of 50~60S, the temperature of sodium hydroxide solution is 40~50 DEG C；
Step 4：By by corroding in the liquor ferri trichloridi of step 3 treated pcb board is placed on high temperature, high concentration,
The ratio of ferric trichloride and water is 100g in liquor ferri trichloridi：200g, when corrosion a length of 2~3min, liquor ferri trichloridi
Temperature is 95~100 DEG C；
Step 5：Step 4 will be passed through, and treated that pcb board is cleaned up with pure water, and pure water temperature is 40~50 DEG C；
Step 6：Will by step 5, treated that pcb board is placed in the high-concentration sodium hydroxide solution of room temperature corrodes, it is high
The ratio of sodium hydroxide and water is 100g in sodium hydroxide solution：1000g, when corrosion a length of 1~2min；
Step 7：Step 6 will be passed through, and treated that pcb board cleans up.
In order to enable exposure is faster, production time cost, in step 2, UV light vertical irradiation film plates are saved.
In order to enable pcb board can carry out the reaction described in step 6 with 40~50 DEG C of temperature, avoid because uprushing
The temperature difference, and cause to split glue, cause the circuit copper wire on pcb board to be broken, the step 5 further includes that will be cleaned up with pure water
PCB is placed in drying equipment and dries, and drying temperature is 40~50 DEG C.
Preferably, the photoresists described in step 1 are one-pack-type photoresists.
Preferably, in step 7 it is described will pass through step 6 treated pcb board cleans up using ultrasonic cleaning or
It is placed in pure water and cleans.
Beneficial effects of the present invention：UV light irradiation times are 80~90S, and 60~90 milliwatts of intensity of illumination/square centimeter expose
Light effect is good, and photoresists is enabled to fully to expose；The ratio of sodium hydroxide and water is 10g：The low-concentration sodium hydroxide of 1000g
Corrode in solution, when corrosion a length of 50~60S so that modified photoresists can be sufficiently rinsed totally；High temperature, high concentration
Liquor ferri trichloridi in corrode, in liquor ferri trichloridi the ratio of ferric trichloride and water be 100g：200g, a length of 2 when corrosion
~3min, the temperature of liquor ferri trichloridi are 95~100 DEG C, are enabled to because that the photoresists of denaturation are washed off is exposed
Copper is fully corroded, and high temperature can speed up reaction so that corrosion is fully complete in a short time；It is 40~50 DEG C pure with temperature
Water cleans up, and ensures in corrosion process, to go out in the high-concentration sodium hydroxide solution for the room temperature being placed into described in step 6
The case where existing temperature difference cataclysm, avoiding moment caused by excessive temperature differentials splits glue, and the copper wire on pcb board is caused be broken, destruction
The vehicle of monoblock pcb board works.In entire method, various reactions all carry out in much the same temperature, and reaction temperature is not present
The big difference variation of moment is not in the big difference variation because of moment, and generates harmful effect to pcb board, reduces product
Yield；While the liquor ferri trichloridi of high temperature, high concentration enables to the time for washing copper process to be greatly diminished, simultaneous reactions
Fully completely, the yield rate of product is improved.
The present invention can effectively solve the problem that existing electrical measurement plate production method cannot quickly, it is so efficient that produce asking for electrical measurement plate
Topic, and method is simple and reliable, can be widely applied to the production field of electrical measurement plate.
With reference to embodiment, invention is further described in detail.
