Gweba umgangatho PCB ibhodi ngombala wePCB

Okokuqala, i-PCB, njengebhodi yesekethe eprintiweyo, ikakhulu ebonelela ngonxibelelwano phakathi kwezinto zombane. Umbala awuhambelani ngqo nokusebenza, kwaye umahluko wombala awuchaphazeli ukusebenza kombane. Ukusebenza kwe-PCB kumiselwe zizinto ezisetyenzisiweyo (i-Q ephezulu), uyilo lwe-wiring, kunye nenani leebhodi. Nangona kunjalo, kwinkqubo yokuhlamba i-PCB, umnyama yeyona nto inokubangela umahluko kumbala. Ukuba izinto zokwenza imveliso kunye nenkqubo yemveliso esetyenziswe ngumzi-mveliso we-PCB zahluke kancinane, inqanaba lesiphene se-PCB liya kunyuka ngenxa yomahluko wombala. Oku ngqo kukhokelela ekunyukeni kweendleko zemveliso.

Ngapha koko, izinto ezibonakalayo zePCB zikho kuyo yonke indawo kubomi bethu bemihla ngemihla, yile fiber yeglasi kunye nentlaka. I-fiberglass idibanisa ne-resin kwaye iqinisa kwibhodi efakwe kwi-insulated, i-insulated kwaye ingabi lula. Esi sisiseko sePCB. Ewe, i-PCB substrate eyenziwe ngeglasi yefayibha kunye nentlaka yodwa ayinakuqhuba umqondiso, ke ngoko kwi-substrate ye-PCB, umenzi uya kugubungela umphezulu ngobhedu, ngoko ke i-PCB substrate ingabizwa ngokuba yi-substrate eboshwe ngobhedu.

Ngenxa yokuba umzila wesekethe we-PCB emnyama kunzima ukuyichonga, iya kwandisa ubunzima bokulungiswa kunye nokulungiswa kwe-r & d nasemva kwentengiso. Ngokubanzi, ukuba akukho bhrendi ine-RD (UPHANDO kunye nophuhliso) abayili kunye neqela elinamandla lokugcina elinobuchule obunzulu, i-PCB emnyama ayizukusetyenziswa ngokulula. Kunokuthiwa ukusetyenziswa kwe-PCB emnyama kukubonakalisa ukuzithemba kwe-brand kwi-RD yoyilo kunye neqela lokugcina kade. Ukusuka ecaleni, kukwabonisa ukuzithemba komenzi kumandla abo.

Ngokusekwe kwezi zizathu zingasentla, abavelisi abaphambili baya kuqaphela ngononophelo xa bekhetha uyilo lwenguqulo yePCB yeemveliso zabo. Ke ngoko, uninzi lweemveliso ezithunyelwe ngeemarike ezinkulu kuloo nyaka zisebenzisa i-PCB ebomvu, i-PCB eluhlaza okanye uguqulelo oluhlaza okwesibhakabhaka. I-PCB emnyama inokubonwa kuphela kwimveliso esembindini kunye nesiphelo esiphakamileyo okanye iimveliso eziphambili, ke sukucinga ukuba i-PCB emnyama ingcono kune-PCB eluhlaza kwakhona.
