When most pcb manufacturers carry out PCB welding board turnover in the workshop, due to the heavier pcb board, when the components are soldered by hand, the improper movement operation will cause the components on the PCB board to fall off and the probability of collision will be very high.
So how to turnover the PCBA board is the safest, the following is the advice given by FASTPCBA, I hope to help you.
Use an anti-static foam tray for turnaround, not only to relax the design, but also to prevent components from being knocked out.
For PCB boards with lighter components and different height differences, foam cushion can be used, so that when the PCB board is pulled, the components do not slide directly on the table and can be prevented from being knocked off.
For pcb boards with heavier components and high component heights difference, it is necessary to use the tooling pads for the back side welding.
When PCB is carrying out SMT chip processing (SMT), there are usually 3 methods (based on the situation of opening the steel mesh): all manual, semi-automatic, and fully automatic. All manual is to brush the steel mesh, and the electronic components are placed manually. Semi-automatic refers to b...
, and connect them to complete specific functions of the circuit. Compared with discrete component circuits, integrated circuits greatly reduce the volume, weight, number of lead wires and solder joints of point circuits, and improve circuit performance and reliability. The miniaturization, minia...
PCB circuit board proofing or board making requires a lot of information, and the difference in each item will have a huge impact on the final price. Size, board thickness, surface treatment, resistance resistance, solder mask coverage, solder mask color, gold finger, copper foil thickness, etc. ...
