When doing DIP plug-in, the PCB must be flat. After that, the surface of the circuit board must be kept flat without warping. The side with the font must be on it.
Make sure that the post-welded pins cannot cover the pads.
For components with two-way direction signs, you must pay attention to the direction.
The strength of sticking for sensitive parts should not be too great, which will easily cause damage to the following components and PCB board. Once one aspect is damaged, the entire circuit board will be out of use.
Should not exceed the edge of the PCB board. Pay attention to its height and pin spacing, and keep it within a reasonable range.
When the DIP plug-in unit is processed, the board surface must be smooth and clean, and there must be no oil or other dirt. Once the circuit board is dirty or oily, then this circuit board will be out of use.
