Okokuqala kuzo zonke, njengoba a ibhodi lesifunda eliphrintiwe , I-PCB ihlinzeka ngokuyinhloko ukuxhumana phakathi kwezingxenye ze-elekthronikhi.Abukho ubuhlobo obuqondile phakathi kombala nokusebenza, futhi umehluko we-pigments akuphazamisi izakhiwo zikagesi.

I ukusebenza kwe Ibhodi le-PCB kunqunywa izici ezifana nezinto ezisetshenzisiwe (inani eliphezulu le-Q), ukwakheka kwezintambo, nezingqimba ezimbalwa zebhodi.Kodwa-ke, ngesikhathi sokugeza i-PCB, ubumnyama yibo okungenzeka bubangele ukuhluka kwemibala.Uma izinto zokusetshenziswa nezinqubo zokukhiqiza ezisetshenziswa ifekthri ye-PCB zihluke kancane, izinga lokungasebenzi le-PCB lizonyuka ngenxa yomehluko wombala.Lokhu kuholela ngqo ekwenyukeni kwezindleko zokukhiqiza.

Ku Eqinisweni, izinto zokusetshenziswa ze-PCB zikhona 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-ke i-substrate ye-PCB ingabuye ibizwe ngokuthi ibhodi lesifunda eliphrintiwe le-copper-clad.

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

Isekelwe kulezi zizathu ezingenhla, abakhiqizi abakhulu bazocabangela ngokucophelela lapho bekhetha imiklamo ye-PCB yemikhiqizo yabo.Ngakho-ke, iningi lemikhiqizo enokuthunyelwa okukhulu emakethe ngalowo nyaka yasebenzisa i-PCB ebomvu, i-PCB eluhlaza, noma izinguqulo ze-PCB eziluhlaza.Ama-PCB amnyama angabonwa kuphela emikhiqizweni ephakathi kuya kwephezulu noma ephezulu, ngakho-ke ungakholwa ukuthi ama-PCB amnyama angcono kunoluhlaza.
