First of all, as the 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. Ukusebenza kwebhodi ye-PCB kugqitywa zizinto ezifana nezixhobo ezisetyenzisiweyo (ixabiso eliphezulu le-Q), uyilo lwe-wiring kunye neengqimba ezininzi zebhodi. Nangona kunjalo, kwinkqubo yokuhlamba i-PCB, umnyama yeyona nto inokubangela umahluko wombala. Ukuba imathiriyeli ekrwada kunye nenkqubo yokuvelisa esetyenziswa ngumzi-mveliso wePCB yahluke kancinane, izinga lesiphako sePCB liya kwanda ngenxa yomahluko wombala. Oku kukhokelela ngokuthe ngqo ekunyukeni kweendleko zemveliso.

Loluphi uhlobo lwempembelelo umbala wePCB unalo ekusebenzeni kwayo?

Ngapha koko, izinto ezikrwada zePCB zibonwa kuyo 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 yi-copper-clad substrate.

Njengoko umkhondo wesekethe we-PCB emnyama kunzima ukuchonga, kuya 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. ye. Kunokuthiwa ukusetyenziswa kwe-PCB emnyama kukubonakalisa ukuzithemba kwe-brand kwi-design ye-RD kunye neqela le-post-maintenance. Ukusuka kwicala, ikwayimbonakaliso yokuzithemba komenzi kumandla ayo.

Ngokusekelwe kwezi zizathu zingasentla, abavelisi abakhulu baya kuqwalasela ngenyameko xa ukhetha uyilo lwebhodi yePCB kwiimveliso zabo. Ke ngoko, uninzi lweemveliso ezinokuthunyelwa okukhulu kwimarike ngaloo nyaka zasebenzisa iPCB ebomvu, iPCB eluhlaza okanye inguqulelo yePCB eluhlaza okwesibhakabhaka. IiPCB eziMnyama zinokubonwa kuphela kumbindi ukuya phezulu okanye kwiimveliso eziphambili, ke abathengi akufuneki baphinde bacinge ngeePCB ezimnyama. I-PCB ingcono kune-PCB eluhlaza.
