Magulu osindikizira a dera (PCBs) nthawi zambiri samanyalanyazidwa m'mayiko amakono, komabe amagwira ntchito yofunika kwambiri pazida zonse zamagetsi zomwe timagwiritsa ntchito masiku ano.Kaya ndi foni yanu yam'manja, laputopu, kapena zida zanzeru zomwe zili m'nyumba mwanu, ma PCB ndi ngwazi zomwe zimapangitsa kuti zidazi zizigwira ntchito mosavutikira.Mubulogu iyi, tifufuza dziko la ma PCB, tikupeza zomwe ali komanso momwe amagwirira ntchito.
Thupi:
1. Chidziwitso choyambirira cha PCB
Pulojekiti yosindikizidwa (PCB) ndi pepala lochepa kwambiri la insulating (nthawi zambiri fiberglass) yokhala ndi zitsulo zopangira zitsulo zokhazikika.Njirazi zimakhala ngati njira zolumikizira zizindikiro zamagetsi pakati pa zida zamagetsi.Kukula, zovuta ndi chiwerengero cha zigawo za PCB zingasiyane malinga ndi zofunikira za chipangizo.
2. Zigawo za PCB
Ma PCB amapangidwa ndi zinthu zosiyanasiyana kuphatikiza ma resistors, capacitors, diode, transistors ndi ma circuit Integrated (ICs).zigawo izi soldered kwa PCB, kupanga kugwirizana magetsi pakati pawo.Chigawo chilichonse chimakhala ndi gawo linalake mu dera ndipo chimathandizira kuti pakhale ntchito yonse ya chipangizocho.
3. Momwe PCB imagwirira ntchito
PCB imagwira ntchito polola kuti ma siginecha amagetsi aziyenda pakati pa zigawo zosiyanasiyana, kuwonetsetsa kuti amalumikizana ndikuchita ntchito zomwe apatsidwa.Kufufuza kwachitsulo pa PCB kumapereka njira zofunikira zotumizira zizindikiro.Zigawo za PCB zimayikidwa mwadongosolo molingana ndi kapangidwe ka dera kuti ziwongolere ntchito ndikuchepetsa kusokoneza.
4. Njira yopanga
Ma PCB amapangidwa kudzera munjira zingapo.Choyamba, mapangidwe a dera amapangidwa pogwiritsa ntchito mapulogalamu a makompyuta (CAD).Mapangidwewo amasamutsidwa ku PCB pogwiritsa ntchito njira ya photolithographic.Kenako bolodi imakhomedwa kuti ichotse mkuwa wosafunikira ndikusiya zotsalira zomwe mukufuna.Potsirizira pake, zigawozo zimagulitsidwa pa bolodi ndikuyang'aniridwa ndi khalidwe labwino musanaphatikizidwe mumagetsi.
5. Ubwino ndi kuipa kwa PCB
Ma PCB ali ndi zabwino zambiri monga kudalirika, kuphatikizika, kumasuka kwa kupanga misa, komanso kuyenda kwazizindikiro koyenera.Komabe, amakhalanso ndi malire, kuphatikizapo kusasinthasintha, kukwera mtengo koyambira koyamba, komanso kufunikira kwa zida zapadera zopangira.
Mapeto
Ma board osindikizira (PCBs) ndiye msana wamagetsi amakono, zomwe zimapangitsa kuti zida zathu zatsiku ndi tsiku zizigwira ntchito bwino.Kudziwa mmene PCB imagwirira ntchito kungatithandize kuyamikira kwambiri luso lamakono la chipangizochi.Kuchokera pamapangidwe oyambira mpaka kupanga, PCB ndichinthu chofunikira kwambiri chomwe chimayendetsa kupita patsogolo kwaukadaulo.Pamene tikupitiliza kukumbatira kupita patsogolo kwa digito, ma PCB mosakayikira apitiliza kusinthika ndikusintha tsogolo lazamagetsi.
