Kugwiritsa ntchito PCB bolodi imadziwika ndi aliyense ndipo imawoneka pafupifupi pazinthu zonse zamagetsi. Kukula kwa sayansi ndi ukadaulo kumalimbikitsa kukula kwa mafakitale ama board a PCB, ndipo anthu ali ndi zofunikira kwambiri pamitundu, kulondola komanso kudalirika kwa zida. Pali mitundu yambiri yama board a PCB pamsika, ndipo ndizovuta kusiyanitsa mtunduwo. Pankhaniyi, zotsatirazi kuti zikuphunzitseni njira zingapo zodziwira bolodi la PCB.

Choyamba, kuweruza kuchokera pawonekedwe

1. Maonekedwe a weld

Chifukwa pali magawo ambiri a PCB, ngati kuwotcherera sikuli bwino, magawo a PCB adzagwa mosavuta, omwe amakhudza kwambiri kuwotcherera ndi mawonekedwe a PCB. Chifukwa chake, ndikofunikira kwambiri kuwotcherera molimba.

Malamulo oyimira kukula ndi makulidwe

Chifukwa bolodi la PCB lili ndi makulidwe osiyana ndi bolodi la PCB, ogwiritsa ntchito amatha kuyeza ndikufufuza malinga ndi zofuna zawo.

3. Kuwala ndi utoto

Nthawi zambiri bolodi lakunja la PCB limakutidwa ndi inki kuti ichite kutchinjiriza, ngati mtundu wa bolodi suli wowala, inki yocheperako, zomwe zikuwonetsa kuti bolodi lotsekemera palokha silabwino.

Awiri, kuchokera pa mbale kuti aweruze

1. Makatoni wamba a HB ndiotsika mtengo komanso osavuta kusandulika ndi kuphwanya, chifukwa chake amatha kupanga gulu limodzi. Mtundu wa mawonekedwe akewo ndi wachikaso chakuda, wokhala ndi fungo losangalatsa, ndipo zokutira zamkuwa ndizoyipa komanso zoonda.

2, single 94V0, bolodi la CEM-1, mtengowo ndiwokwera kwambiri kuposa bolodi, kapangidwe kake kakapangidwe kake ndimtundu wachikaso, makamaka wogwiritsira ntchito matabwa a mafakitale ndi matabwa amagetsi okhala ndi zofunikira pamoto.

3. Galasi yamagalasi yamagalasi imakhala yotsika mtengo, yamphamvu komanso yobiriwira yobiriwira. Kwenikweni, matabwa ambiri a PCB amapangidwa ndi izi. Ziribe kanthu mtundu wanji wa inki yosindikiza ya PCB yosalala, sangakhale ndi mkuwa wonama komanso chodabwitsa.

Kudziwa mfundo zomwe zili pamwambapa, sizovuta kwenikweni kuzindikira bolodi la PCB.
