M'kati mwa SMT chip processing,dera lalifupindi wamba kwambiri osauka processing chodabwitsa.The yochepa circuited PCBA dera bolodi sangathe ntchito bwinobwino.Zotsatirazi ndi wamba kuyendera njira kwa dera lalifupi la PCBA bolodi.

1. Ndibwino kuti mugwiritse ntchito kachipangizo kakang'ono kamene kamayendera dera kuti muwone ngati mulibe vuto.

2. Pakakhala maulendo ambiri afupikitsa, tikulimbikitsidwa kutenga bolodi la dera kuti mudulire mawaya, ndiyeno mphamvu pa dera lililonse kuti muwone madera omwe ali ndi maulendo afupikitsa limodzi ndi limodzi.

3. Ndibwino kuti mugwiritse ntchito multimeter kuti muwone ngati dera lofunikira ndilofupikitsa.Nthawi iliyonse chigamba cha SMT chikamalizidwa, IC iyenera kugwiritsa ntchito makina owerengera kuti izindikire ngati magetsi ndi nthaka ndizofupikitsidwa.

4. Yatsani maukonde afupipafupi pa chithunzi cha PCB, yang'anani malo omwe ali pa bolodi la dera kumene dera lalifupi likhoza kuchitika, ndipo samalani ngati pali dera lalifupi mkati mwa IC.

5. Onetsetsani kuti mukuwotcherera mosamala zigawo zing'onozing'ono za capacitive, mwinamwake dera lalifupi pakati pa magetsi ndi pansi ndilotheka kwambiri.

6. Ngati pali chipangizo cha BGA, chifukwa zambiri zazitsulo za solder zimaphimbidwa ndi chip ndipo zimakhala zosavuta kuziwona, ndipo ndi matabwa ozungulira ma multilayer, tikulimbikitsidwa kuti tidule mphamvu ya chip iliyonse pakupanga mapangidwe. , ndi kuwalumikiza ndi mikanda maginito kapena 0 ohm kukana.Pakachitika nthawi yaying'ono, kulumikiza kuzindikirika kwa maginito kumapangitsa kuti zikhale zosavuta kupeza chip pa board board.
