Dangane da kayan ƙarfafa hukumar PCB, gabaɗaya an raba shi zuwa nau'ikan masu zuwa:

1. Phenolic PCB takarda substrate

Domin irin wannan allo na PCB yana kunshe da tarkacen takarda, katako, da dai sauransu, wani lokaci yakan zama kwali, allon V0, allo mai kare wuta da 94HB, da dai sauransu. Babban kayansa shine takarda fiber na itace, wanda shine nau'in PCB. hada da phenolic guduro matsa lamba.allo.

Irin wannan nau'in takarda ba shi da wuta, ana iya buga shi, yana da ƙananan farashi, ƙananan farashi, da ƙarancin dangi.Sau da yawa muna ganin phenolic takarda substrates kamar XPC, FR-1, FR-2, FE-3, da dai sauransu. Kuma 94V0 nasa ne na harshen wuta-retardant paperboard, wanda ba shi da wuta.

2. Composite PCB substrate

Irin wannan katakon foda kuma ana kiransa foda, tare da takarda fiber fiber takarda ko auduga fiber fiber takarda azaman kayan ƙarfafawa, da gilashin fiber gilashi azaman kayan ƙarfafa saman.Abubuwan biyu an yi su ne da resin epoxy mai hana harshen wuta.Akwai fiber gilashin rabin gilashin guda ɗaya mai gefe guda 22F, CEM-1 da allon gilashin rabin gilashin CEM-3, daga cikinsu CEM-1 da CEM-3 sune mafi yawan abubuwan haɗin ginin ƙarfe na ƙarfe.

3. Gilashin fiber PCB substrate

Wani lokaci shi ma ya zama epoxy jirgin, gilashin fiber jirgin, FR4, fiber jirgin, da dai sauransu Yana amfani da epoxy guduro a matsayin m da gilashin fiber zane a matsayin ƙarfafa abu.Irin wannan allon kewayawa yana da babban zafin aiki kuma yanayin bai shafe shi ba.Ana amfani da irin wannan allon sau da yawa a cikin PCB mai gefe biyu, amma farashin ya fi tsada fiye da na'urar PCB mai hade, kuma kauri na kowa shine 1.6MM.Irin wannan nau'in na'ura ya dace da allunan samar da wutar lantarki daban-daban, manyan allunan kewayawa, kuma ana amfani da su sosai a cikin kwamfutoci, kayan aiki na gefe, da kayan sadarwa.
