PCB assembly and soldering is the main process of PCB Assembly processing. It means that some components cannot be gone through wave soldering due to the design process, high materials, or inability to withstand high temperatures, which need to use the electric soldering iron for manual soldering. The PCB assembly and soldering of the plug-in are generally performed after the wave soldering of the inserted PCB board is completed, so it is called post-welding processing.
Not only do components assembly and soldering, but we can also provide PCB soldering services, we can solder cables and wires on the PCB boards. Another important use is that manual assembly able to be adequately inspected by the automated optical inspection equipment and requires a technician to verify their placement and touch up any soldering problems. Some surface mount connectors may also require manual inspection and touch-up.
Smaller components that may have “floated” during reflow or are prone to solder bridging also require manual cleanup by a technician.
