PCB Processing Process Requirements

PCB is mainly to power supply processing of the main board, its processing process is basically not complicated, mainly SMT machine placement, wave soldering machine welding, manual plug-in, etc., power control board in the process of SMD processing, the main process requirements are as follows.
1.Power supply board is the control circuit processing, so the PCB board needs to be resistant to high temperature requirements, the need for lead-free process.
2.The temperature resistance value of the components need to meet the molten tin requirements of electronic components (generally above 200 degrees to about 50-100s, Z high temperature above 250 degrees).
3.The electronic component’s placement pitch, the big material and the small material’s distance cannot be less than 1mm, 0603 the following five kinds of pitch should be greater than 0.3mm.
4.The transmission side of the power control board can’t have a gap.
5.The pad cannot have over line hole, the component pad periphery cannot have leakage tin hole, the packaging needs to conform to the large material device packaging requirements.
Part of the customer’s power control board has double-sided mounting requirements, this involves the relevant ability of the equipment and the speed of the production line change line, the process flow of double-sided mounting is A side solder paste printing – SMD – reflow oven soldering – flip board – B side solder paste printing -SMT pick and place-Reflow soldering.
