Ekuqaleni kuzo zonke, njenge ibhodi yesekethe eprintiweyo , PCB ikakhulu ibonelela uqhagamshelwano phakathi amacandelo elektroniki.Akukho budlelwane obuthe ngqo phakathi kombala kunye nokusebenza, kwaye ukuhlukana kwee-pigments akuchaphazeli iimpawu zombane.

I ukusebenza kwe ibhodi PCB kumiselwa yimiba efana nesixhobo esisetyenzisiweyo (ixabiso eliphezulu le-Q), uyilo lwe-wiring, kunye neengqimba ezininzi zebhodi.Nangona kunjalo, kwinkqubo yokuhlamba i-PCB, umnyama ngowona unokubangela ukungafani kombala.Ukuba imathiriyeli ekrwada kunye neenkqubo zokuvelisa ezisetyenziswa ngumzi-mveliso wePCB zahluke kancinane, izinga lesiphako sePCB liya kwanda ngenxa yomahluko wombala.Oku kukhokelela ngokuthe ngqo ekunyukeni kweendleko zemveliso.

Kwi Inyani, izinto ezikrwada zePCB zikuyo yonke indawo kubomi bethu bemihla ngemihla, oko kukuthi, ifayibha yeglasi kunye neresin.I-fiber yeglasi kunye ne-resin zidityanisiwe kwaye lukhuni ukuba ibe yi-heat-insulating, insulating, kwaye akukho lula ukugoba ibhodi, eyi-PCB substrate.Ewe kunjalo, i-PCB substrate eyenziwe ngefiber yeglasi kunye ne-resin iyodwa ayikwazi ukwenza imiqondiso.Ngoko ke, kwi-substrate ye-PCB, umenzi uya kugubungela umaleko wobhedu phezu komhlaba, ngoko ke i-substrate ye-PCB inokubizwa ngokuba yibhodi yesekethe eprintiweyo yobhedu.

Njengoko umkhondo wesekethe ye-PCB emnyama kunzima ukuyichonga, iya kwandisa ubunzima bokulungisa kunye nokulungiswa kweempazamo kwi-R & D kunye nezigaba emva kokuthengisa.Ngokubanzi, ukuba akukho phawu olunabayili be-RD (R&D) olunzulu kunye neqela eliqinileyo lokugcinwa, iiPCB ezimnyama aziyi kusetyenziswa lula.Kunokuthiwa ukusetyenziswa kwe-PCB emnyama kukuzithemba kwe-brand kwi-design ye-RD kunye neqela le-post-maintenance.Kwelinye icala, ikwayimbonakaliso yokuzithemba komenzi kumandla ayo.

Ngokusekelwe kwezi zizathu zingasentla, abavelisi abakhulu baya kuqwalasela ngenyameko xa bekhetha uyilo lwePCB kwiimveliso zabo.Ke ngoko, uninzi lweemveliso ezinokuthunyelwa okukhulu kwimarike ngaloo nyaka zasebenzisa iPCB ebomvu, iPCB eluhlaza, okanye iinguqulelo zePCB eziluhlaza.IiPCB eziMnyama zinokubonwa kuphela kumbindi ukuya phezulu okanye kwiimveliso eziphezulu, ke musa ukukholelwa ukuba iiPCB ezimnyama zingcono kunoluhlaza.
