Bambanci Tsakanin PCBs na yumbu da PCBs na gargajiya na FR4
Kafin mu tattauna wannan batu, bari mu fara fahimtar menene PCBs na yumbu da kuma menene PCBs na FR4.
Allon Da'irar Yumbu yana nufin wani nau'in allon da'ira da aka ƙera bisa kayan yumbu, wanda kuma aka sani da PCB na yumbu (allon da'ira da aka buga). Ba kamar sauran filastik da aka ƙarfafa da zare na gilashi (FR-4) ba, allunan da'irar yumbu suna amfani da surorin yumbu, waɗanda za su iya samar da kwanciyar hankali mafi girma a zafin jiki, ƙarfin injiniya mafi kyau, kyawawan halayen dielectric, da tsawon rai. Ana amfani da PCB na yumbu galibi a cikin da'irori masu zafi, masu yawan mita, da masu ƙarfin wuta, kamar fitilun LED, amplifiers na wutar lantarki, na'urorin semiconductor, na'urorin watsa RF, na'urori masu auna firikwensin, da na'urorin microwave.
Allon Da'ira yana nufin wani abu na asali don kayan lantarki, wanda kuma aka sani da PCB ko allon da'ira da aka buga. Yana ɗaukar kaya ne don haɗa kayan lantarki ta hanyar buga tsare-tsaren da'irar ƙarfe akan abubuwan da ba sa dawwama, sannan kuma ƙirƙirar hanyoyin dawwama ta hanyar hanyoyin kamar lalata sinadarai, jan ƙarfe na electrolytic, da haƙa.
