Shenzhen Jie Du State Technology Co., Ltd.is committed to the continuous improvement of the电子元器件service, become a society, customers, shareholders and employees long-term trust of the company. Our Company adhering to pirit of for the sake of customers, and win-win with customers , and through Jieduo state technology staff continuous innovation and development to provide first-class multilayer PCB prototype,pcb prototype design,PCB Manufacturing the difference,custom pcb boards for enterprises , is what we have been working for. Details:
PCB Manufacturing
Production of the circuit board mini, visualization, and for optimizing production plays an important role in fixing circuit with the electrical layout.
PCB board, PCB board, aluminum plate, high frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printing (copper etching technology circuit board, etc. circuit board makes the circuit mini, visualization , For the fixed circuit of mass production and optimization of electrical appliances play an important role.
First, print the circuit board
Will draw a good circuit board with a transfer paper to print out, pay attention to the sliding side of their own, the general print two circuit boards, that is, a piece of paper to print two boards. In which to choose the best print production board.
Cutting copper cladding
Use the photosensitive plate to make the circuit board full diagram. CCL, that is, both sides are covered with copper film circuit board, the CCL cut into the size of the circuit board, not too large to save material.
Pretreatment of CCL
With fine sandpaper on the surface of the copper oxide layer polished off to ensure that the transfer circuit board, the thermal transfer paper on the toner can be firmly printed on the CCL, polished the standard is bright, no obvious Stains.
Transfer circuit board
Will print the printed circuit board cut into the appropriate size, printed on the side of the printed circuit board on the CCL, aligned after the CC into the thermal transfer machine, put into the paper must ensure that the transfer paper is not dislocation. In general, after 2-3 times the transfer, the circuit board can be very strong transfer on the CCL. Heat transfer machine has been preheated in advance, the temperature set at 160-200 degrees Celsius, due to the high temperature, the operation of attention to safety!
Corrosion circuit board
First check whether the printed circuit board is complete, if there is a small number of places can not be transferred with a black oil pen repair. And then can be corroded, and so on the circuit board exposed copper film is completely corroded, the circuit board removed from the etching solution clean, so that a circuit board corrosion is good. The composition of the etching solution is concentrated hydrochloric acid, concentrated hydrogen peroxide, water, the ratio of 1: 2: 3, in the preparation of corrosive solution, the first water, then concentrated hydrochloric acid, concentrated hydrogen peroxide, if the operation of concentrated hydrochloric acid, concentrated hydrogen peroxide or corrosive solution Carefully splashed on the skin or clothing to be cleaned with water in time, due to the use of strong corrosive solution, the operation must pay attention to safety!
Circuit board drilling
The circuit board is to ｉｎｓｅｒｔ the electronic components, so it is necessary to drill the circuit board. According to the thickness of the electronic components of the pin to choose a different drill, drilling machine in the use of drilling, the circuit board must be stable, the rig speed can not open too slow, please carefully look at the operator operation.
Circuit board pretreatment
After drilling, with fine sandpaper to cover the toner on the circuit board polished, with water to clean the circuit board. After drying the water, with rosin painted on the side of the line, in order to speed up the rosin solidification, we use the hot air heater circuit board, just 2-3 minutes rosin can be solidified.
With the purpose of "Quality first, service is paramount" in Jieduo state technology, our strict product quality control system ensures that PCB Prototype Factory,China PCB manufacturer and other products of high quality and stability. We have a first-class laboratory equipment and a highly experienced profess
