Mukasankha mtundu bolodi losindikizidwa (yemwenso amadziwika kuti PCB), mwina mungadabwe kuti njira yolumikizira PCB ndi yolondola bwanji. Kupanga kwa PCB kwasintha kwambiri kwazaka zambiri, chifukwa cha zatsopano m’matekinoloje atsopano omwe alola opanga oyendetsa dera kuti apange zatsopano molondola komanso mwaluso.

Umu ndi momwe mungapangire ziwonetsero za PCB ndendende.

Kutsogolo kwa zomangamanga kuyendera

Musanatchule PCB, pali zinthu zambiri zomwe zingagwiritsidwe ntchito kukonzekera zotsatira zake. Choyamba, wopanga PCB adzawerenga mosamala mapangidwe a bolodi (Gerber document) ndikuyamba kukonzekera gulu, lomwe limalemba malangizo mwatsatane-tsatane pakupanga. Pambuyo powunikira, mainjiniya amasintha mapulani awa kukhala mtundu wazidziwitso zomwe zingathandize kupanga PCB. Injiniya ayang’ananso mtundu wavuto lililonse kapena kuyeretsa.

Deta iyi imagwiritsidwa ntchito popanga komaliza komaliza ndikuipatsa nambala yapadera yazida. Nambalayi imayang’ana njira yomanga PCB. Ngakhale kusintha kwakung’ono kwambiri pakuwunikiranso kwa board kumabweretsa nambala yatsopano yazida, zomwe zimathandizira kuwonetsetsa kuti palibe chisokonezo panthawi ya PCB komanso kupanga mitundu yambiri.

kujambula

Pambuyo pofufuza mafayilo olondola ndikusankha gulu loyenera kwambiri, kusindikiza kwazithunzi kumayamba. Ichi ndiye chiyambi cha ntchito yopanga. Photoplotters amagwiritsa lasers kujambula dongosolo, zowonetsera silika ndi zithunzi zina zazikulu pa PCB.

Laminating ndi kuboola

Imodzi mwa mitundu itatu yayikulu yamatabodi osindikizidwa, omwe amadziwika kuti ma PCBS angapo, imafuna kuyimitsidwa kuti iziphatikizira pamodzi. Izi nthawi zambiri zimachitika pogwiritsa ntchito kutentha komanso kupanikizika.

Pambuyo popaka mankhwalawo, makina obowolera adzakonzedwa kuti abowole molondola komanso molondola. Njira yobowola imatsimikizira kuti palibe cholakwika chilichonse panthawi yopanga PCB.

Kuyika mkuwa ndi matumba

Magawo amkuwa omwe amaikidwa ndi electrolysis ndi ofunikira kuti magwiridwe antchito amitundu yonse amasindikizidwe. Pambuyo pa electroplating, PCByo imakhala yoyenda bwino ndipo mkuwa umasankhidwa pamtunduwu pogwiritsa ntchito njira yamagetsi. Mawaya amkuwa awa ndi njira zomwe zimalumikiza mfundo ziwiri mkati mwa PCB.

Pambuyo poyesa kuyesa kutsimikizika kwamtundu woyenera wa PCB, adapangidwa kukhala magawo osiyirana ndipo pamapeto pake adayang’ana ukhondo.
