1, SMT patch processing technicians wear the electrostatic ring that is OK, and check the electronic components of each order without errors/mixing, damage, deformation, scratches and other adverse phenomena before plug-in.
2. The plug-in board of the circuit board needs to prepare the electronic materials in advance, and pay attention to the correct polarity direction of the capacitor.
3, after the SMT printing operation is completed, no missing insert, reverse insert, dislocation and other bad products are inspected, and good tin finished products will flow into the next process.
4, SMT patch processing and assembly operations, please wear electrostatic ring, metal close to the wrist skin and keep well grounded, alternating hands work.
5, USB/IF seat/shielding cover/high frequency head/network port terminals and other metal components, plug-in must wear finger sleeve operation.
6. The position and direction of the inserted components must be correct, the components are flat on the board, and the height components are inserted into the K-pin position.
7. If the material is found inconsistent with SOP and BOM, report to the team leader in time.
8, the material should be handled lightly. Do not drop the PCB board after the early process of SMT chip processing and cause damage to the components, and the crystal vibration can not be used.
9, smt chip processing staff before work, please clean the work surface, and keep clean.
