Kedu ihe bụPCBụkpụrụ nlele anya?

1. Nkwakọ ngwaahịa: nkwakọ akpa ikuku na-enweghị agba, nke nwere desiccant n'ime, juru n'ọnụ
2. Mbipụta ihuenyo silk: Mbipụta ihuenyo silk nke mkpụrụedemede na akara dị n'elu PCB ga-edo anya ma doo anya, na agba ga-agbaso ụkpụrụ ahụ, na-enweghị mbipụta ugboro ugboro, mbipụta na-efu efu, mbipụta ọtụtụ, mgbanwe ọnọdụ, na misprinting.
3. Board edge board surface: Lelee ma enwere ntụpọ, sundries, olulu, tin slag residues na PCB elu; ma ọ bụ n'elu osisi a na-akpụ akpụ ma kpughee ya na mkpụrụ; Enwere akwa akwa, wdg.
4. Ndị na-eduzi: Ọ dịghị obere sekit, sekit mepere emepe, ọla kọpa ekpughere na onye nduzi, foil ọla kọpa na-ese n'elu mmiri, wiring mgbakwunye, wdg. Pads: The pads kwesịrị ịbụ tinned nke ọma, na ọla kọpa ekwesịghị ikpughe, mebie, kpụpụ ya, deformed, wdg. .
5. Oghere: Lelee n'ihu ogbe gara aga nke ezigbo PCB iji lelee ma enwere oghere oghere na-efu, ọtụtụ oghere oghere, oghere egbochiri, na ntụgharị oghere. Ihe mkpuchi solder: Ị nwere ike iji bọọdụ ịsa mmiri na-ehicha ya n'oge nyocha iji lelee adhesion ya, lelee ma ọ ga-adapụ, ma enwere egosipụta, ma enwere ihe nrụzi ọ bụla, wdg.
