First of all, as the ibhodi yesifunda ephrintiwe, I-PCB ihlinzeka ngokuyinhloko ukuxhumana phakathi kwezingxenye ze-elekthronikhi. Abukho ubuhlobo obuqondile phakathi kombala nokusebenza, futhi umehluko we-pigments akuphazamisi izakhiwo zikagesi. Ukusebenza kwebhodi le-PCB kunqunywa izici ezifana nezinto ezisetshenzisiwe (inani eliphezulu le-Q), ukwakheka kwezintambo kanye nezingqimba ezimbalwa zebhodi. Kodwa-ke, ngesikhathi sokugeza i-PCB, ubumnyama yibona okungenzeka bubangele umehluko wombala. Uma izinto zokusetshenziswa kanye nenqubo yokukhiqiza esetshenziswa ifekthri ye-PCB ihluke kancane, izinga lokungasebenzi le-PCB lizonyuka ngenxa yomehluko wombala. Lokhu kuholela ngqo ekwenyukeni kwezindleko zokukhiqiza.

Hlobo luni lwethonya umbala we-PCB onalo ekusebenzeni kwayo?

Eqinisweni, izinto zokusetshenziswa ze-PCB zibonakala yonke indawo ekuphileni kwethu kwansuku zonke, okungukuthi, i-glass fiber kanye ne-resin. I-fiber yengilazi kanye ne-resin kuhlangene futhi kuqiniswe ukuze kube yi-heat-insulating, insulating, futhi akulula ukugoba ibhodi, okuyi-substrate ye-PCB. Vele, i-PCB substrate eyenziwe nge-glass fiber kanye ne-resin iyodwa ayikwazi ukwenza amasiginali. Ngakho-ke, ku-substrate ye-PCB, umenzi uzovala ungqimba lwethusi ngaphezulu, ngakho i-substrate ye-PCB ingabuye ibizwe ngokuthi i-copper-clad substrate.

Njengoba imikhondo yesifunda ye-PCB emnyama kunzima ukuyibona, izokwandisa ubunzima bokulungisa nokulungisa iphutha ku-R&D nezigaba zangemuva kokuthengisa. Ngokuvamile, uma lungekho uhlobo olunabaklami abajulile be-RD (R&D) kanye nethimba eliqinile lokunakekela, ama-PCB amnyama ngeke asetshenziswe kalula. kwe. Kungashiwo ukuthi ukusetshenziswa kwe-PCB emnyama kuwukubonakaliswa kokuzethemba komkhiqizo ekwakhiweni kwe-RD kanye nethimba lokunakekelwa kwangemva kwesondlo. Kusukela ohlangothini, futhi kuwukubonakaliswa kokuzethemba komkhiqizi emandleni akhe.

Ngokusekelwe kuzizathu ezingenhla, abakhiqizi abakhulu bazocabangela ngokucophelela lapho bekhetha imiklamo yebhodi le-PCB yemikhiqizo yabo. Ngakho-ke, iningi lemikhiqizo enokuthunyelwa okukhulu emakethe ngalowo nyaka yasebenzisa i-PCB ebomvu, i-PCB eluhlaza noma inguqulo ye-PCB eluhlaza okwesibhakabhaka. Ama-PCB amnyama angabonakala kuphela emikhiqizweni ephakathi kuya kwephezulu noma ephezulu, ngakho amakhasimende akufanele esacabanga ngama-PCB amnyama. I-PCB ingcono kune-PCB eluhlaza.
