How to Check SMD Soldering Strength?

In our daily works, it is common we need to know what’s the components soldering strength to the PCB boards. Poor soldering strength leads to a high risk of components falling off the board.

Makerfabs use the SMD pulling tester to sample test the soldering strength for the components:

Normally, the pull strength testing as follows:
1. Pulling the components directly with the tester, pulling angle  30~45 degree;
2. Pulling time 10S;
3. The pulling standard as follows:

With these testing, we can get more detailed info on how the components are soldered on the PCB, to keep our PCBA products better quality.
