PCB solder resistance can be displayed in different colors, including green, white, blue, black, red, yellow, matte color, purple, matte black, matte green, etc. Under normal circumstances, the production of LED lighting products must use white PCB boards, other colors are in accordance with customer needs. The color is customized printed circuit board, which green circuit board is the most common, because the green process is the most mature, the simplest, and its manufacturing cost is more cost-effective, in addition to green and bright green, light green, matte green and the like.

PCB production process is more complicated, usually with inner layer production, blackening, pressing, drilling, plating and other more than 40 processes. Taking rigid circuit boards as an example, they usually include processes such as exposure, etching, copper plating, and film removal. Although the PCB has strong customization characteristics, these most basic processes are necessary, but there will be differences in the specific parameters.

PCBA mainly includes a series of processes such as component procurement, PCB production, SMT assembly, DIP plug-in and PCBA testing. The processes involved are relatively complex, and the pcb assembly price is also relatively complex. To understand the PCBA quotation, it is necessary to clarify the composition of the PCBA total cost, and then break down the cost of each part.
