The printed circuit board assembly is a substrate for assembling electronic parts and is a printed board that forms connection between points and prints components on a general-purpose base material according to a predetermined design.
The Role of PCB Assembly
The main function of this product is to make various electronic components form a predetermined circuit connection, and play the role of relay transmission. It is a key electronic interconnection of electronic products, and is known as the "mother of electronic products". PCB is used as a substrate and a key interconnection for electronic parts. Any electronic equipment or product needs to be equipped.

PCB Assembly Process
PCB assembly is a printed circuit board assembly service. The production process of PCB is relatively complex. It involves a wide range of processes, from simple mechanical processing to complex mechanical processing. There are common chemical reactions and photochemical electrochemical thermochemical processes. Computer-aided design CAM and other knowledge. Moreover, there are many process problems in the production process and new problems will be encountered from time to time.
Some of the problems will disappear without identifying the cause. Since the production process is a discontinuous assembly line, any problem will cause the entire line to stop production. Or the consequences of a lot of scrapping. If the printed circuit board is scrapped, it cannot be recycled and reused. SPEEDPCB has professional senior designers. Our company can also design one-to-one for customers. Experienced designers can reduce development time.

the bad guy is on the right (black body), and the replacement is on the left (white body). to make it work, i folded the smt wings, and carved out a bit off the top of the pcb, to make the wings fit through the pcb. on the other side, just dab the solder, to make a good contact, as seen on another pic (IMG_5907).
