First piece confirmation must be conducted before SMT placement

First piece confirmation must be conducted before SMT placement, and material replacement requires two people to collaborate in verifying compatibility. If necessary, a foolproof system should be activated.

Process specification version

1. Key steps for SMT surface mount preparation: Strictly follow the first article confirmation to ensure that the parameters are consistent with the requirements; 2. Mandatory requirement for material replacement: Two people cooperate to verify the matching degree of materials, and at the same time, a mistake prevention system is launched to avoid errors.

Practical warning version

The first piece confirmation before SMT placement cannot be omitted, and material replacement must be double checked for material matching. If necessary, a foolproof system should be used to strengthen the quality defense line.
