PCB solder mask can be displayed in different colors, including green, white, blue, black, red, yellow, matte, purple, chrysanthemum, bright green, matte black, matte green and so on.
Immersion gold uses the method of chemical deposition, through the chemical redox reaction method to generate a layer of plating, generally thicker, is a chemical nickel gold gold layer deposition method, can achieve a thicker layer of gold.
Now we will be in the heat dissipation, soldering strength, the ability to carry out electronic testing and the difficulty of the manufacture corresponding to the cost of four aspects of the immersion gold manufacture compared with other surface treatment manufacturees.
We all know that, in order to get PCB a good conductivity, the copper on the PCB is mainly electrolytic copper foil, and the copper solder joints in the air exposure time is too long easy to be oxidised,
Whether it is a star concert, indoor 3D special effects, or some office buildings above the advertising screen, the more clear and brilliant screen, the more stringent the requirements of the PCB.
Printed circuit boards (PCBs) are the core components of modern electronic devices and are widely used in all walks of life. The main function of PCBs is to provide mechanical support for electronic components and to achieve circuit connections through conductive paths. Now let's take a closer look at the specific applications of PCBs in various industries and their importance.
As we all know, the gold wire position process is mainly used in SMT patch factories, so what are the advantages or disadvantages of gold wire position for plate making?
