High-performance PCB design is inseparable from the basic knowledge of power supply, and FPGA common sense is indispensable.

Whether reflow, wave or hand soldering, surface tension is a detriment to forming a good solder joint. However, surface tension can be used again in SMT chip processing and reflow soldering.

Electronic products need heat dissipation during operation. Therefore, in the design of PCB circuit schematic diagram, special attention should be paid to thermal design. Now, what rules should the thermal design of PCBA circuit board follow?

The operator shall reserve two or three spaces during loading and ensure that each link operates in a standard manner, preferably with a uniform elastic standard.

such as how many heat sink holes should be reserved for the circuit board, and where the marking position of the silk screen should be, which may be just the parameters written in the design planning, but can effectively reduce the pcba proofing time.
