PCB Circuit Board Pattern

PCB Circuit Board Pattern

The key process for surface mount assembly of this PCB Circuit Board Pattern is the design of the solder paste template. Most importantly, the amount of solder paste deposited on each pad is repeatable and precisely controlled. We think this is very important, we use our own internal industry standard laser cutting machine to precisely cut our stainless steel template by laser.

Product description:

The key process for surface mount assembly of this PCB Circuit Board Pattern is the design of the solder paste template. Most importantly, the amount of solder paste deposited on each pad is repeatable and precisely controlled. We think this is very important, we use our own internal industry standard laser cutting machine to precisely cut our stainless steel template by laser. Modifications and improvements to production templates can be performed at low cost within hours of need, minimizing latency and latency. The through-hole technology used in this PCB Circuit Board Pattern involves mounting electronic components by passing leads through pre-drilled holes in the printed circuit board. The leads are then soldered to a copper track located on the underside of the PCB. This technique requires the leads to be bent perpendicular to the surface of the PCB Circuit Board Pattern, passing through the holes and then bending in the opposite direction to increase mechanical strength. Welding can be applied manually or by welding a wave machine. Once permanently bonded by welding, the excess lead portion is trimmed to have a distinctly smooth bottom surface.
