Component Mounting &Soldering for pcb

Integrated circuit Component Mounting And Soldering.

First, according to the requirements of the drawings, check whether the model and pin position meet the requirements. Welding the first edge welding two pins, so positioned, then left to right, top to bottom, welding.
For capacitors, diodes, and triodes exposed on the printed circuit board, the extra pins must be trimmed.
Welding sequence: The component assembly welding order is: resistors, capacitors, diodes, transistors, integrated circuits, high-power tubes, and other components are first small and large.
