Mtundu wa bolodi wa PCB, monga dzinalo, mukapeza bolodi ya PCB, moyenera kwambiri mutha kuwona mitundu ya mafuta pa bolodi, yomwe ndi yomwe timanena kuti ndi mtundu wa bolodi ya PCB. Mitundu wamba imaphatikizapo zobiriwira, zamtambo, zofiira ndi zakuda, etc. dikirani.
1. Inki yobiriwira ndi yogwiritsidwa ntchito kwambiri, m'mbiri yonse, komanso zotsika mtengo kwambiri pamsika, motero wobiriwira umagwiritsidwa ntchito ndi ambiri opanga zinthu zawo.
2. Pakakhala zochitika wamba, chinthu chonse cha PCB chikuyenera kudutsa njira yopanga ndi SMT nthawi ikamapanga. Mukamapanga bolodi, pali njira zingapo zomwe zimayenera kudutsa m'chipinda chachikaso, chifukwa zobiriwira zimakhala pachikaso cha chipinda chopepukacho ndichabwino kuposa mitundu ina, koma si chifukwa chachikulu.
Mukakhala ndi ma grating zigawo mu SMT, PCB imayenera kudutsa njira monga mawonekedwe a sholide ndi chigamba chomaliza aoi. Njirazi zimafunikira mawonekedwe owoneka bwino. Mtundu wobiriwira wobiriwira uli bwino kuzindikiritsa kwa chida.
3. Mitundu yofala ya PCB imafiira, chikasu, zobiriwira, zamtambo komanso zakuda. Komabe, chifukwa cha mavuto monga kupanga, kuyendera mizere yambiri kumadalirabe chidwi cha masitima. Maso amayang'ana kumayang'ana pa bolodi pansi pa kuwala kolimba. Izi ndi zotopetsa kwambiri. Polankhula, wobiriwira ndiwovulaza m'maso, kotero opanga ambiri pamsika amagwiritsa ntchito PCB Green.
4. Mfundo ya buluu ndi yakuda ndikuti amapezeka motalika monga cobat ndi kaboni, yomwe ili ndi mawonekedwe apadera, komanso mavuto ofupikirako amapezeka pomwe mphamvu yatha. Kuphatikiza apo, ma PC obiriwira amakhala ochezeka, komanso kutentha kwambiri madera omwe amagwiritsidwa ntchito mu sing'anga, nthawi zambiri palibe poizoni adzamasulidwa.
Palinso opanga ochepa pamsika womwe umagwiritsa ntchito mabodi akuda a PCB. Zifukwa zazikuluzikulu za izi ndi zifukwa ziwiri:
Chikuwoneka kwambiri;
Bolo wakuda siosavuta kuwona luntha, lomwe limabweretsa zovuta kwa bolodi;
Pakadali pano, ambiri a mabodi a Android ndi ma PC akuda.
5. Kuyambira pomwe panali mbali zomaliza za zana lomaliza, makampaniwo ayamba kumvetsera mwa mitundu ya PCB, makamaka chifukwa opanga ambiri opanga a Breen PCB ngati mtunduwo ndiwobiriwira, uyenera kukhala wamapeto.
