Prosesu PCBA Yn y dull weldio mae yna dri phrif, yn y drefn honno, yn ail-lenwi sodro, sodro tonnau ac ôl-werthu prosesu'r tri hyn, mae angen cwblhau pob proses weldio gyda chymorth gwahanol offer weldio, lle mae'r broses sodro tonnau a'r broses sodro ail-lenwi yn cael ei chwblhau'n bennaf gyda chymorth offer selio ar raddfa fawr, a chwblhau'r post.
Reflow soldering process is mainly borrowed from the solder paste printer and reflow soldering equipment to complete, wave soldering process will be the main use of wave soldering equipment to complete, both welding process is mainly by equipment operation, and after welding processing is mainly operated by manual operation is completed, with the help of a soldering iron, soldering station, heat gun, tweezers pliers, and other tools, which soldering iron for the after welding processing of the main offer, a gefail, ac offer eraill ar gyfer offer ategol; Gellir rhannu haearn sodro yn ddau fath yn ôl y strwythur, un ar gyfer yr un endothermig ar gyfer y math gwres allanol, mae endothermig oherwydd y craidd haearn sodro a osodir ym mhen yr haearn sodro a chael yr enw, a math gwres allanol haearn sodro yw'r union gyferbyn, er bod strwythur y gwahanol ond eu rolau'n cael eu defnyddio i weldio cydrannau electronig a'u gwifrau.
