Dab tsi yog qhov txawv ntawm iav Fiber Board, iav Fiber Board thiab FR4 Board

1. Kev siv sib txawv. Kev tsim khoom ntawm Circuit Board yog cov khoom siv tseem ceeb yog alkali - dawb iav ntaub, fiber ntau ntawv, epoxy resin. Cov iav fiber ntau: substrate iav fiber ntau daim ntaub, epoxy board: lub binder yog epoxy resin, FR4: substrate paj rwb fiber ntau daim ntawv. Tag nrho peb yog fiberglass.
2. Cov xim sib txawv. General epoxy board nyob rau hauv kev ua lag luam yog phenolic epoxy, daj. Tsis zoo li cov khoom siv hluav taws xob hauv lub hauv paus, hluav taws xob rwb thaiv tsev lub hom phiaj. FR4 yog NEMA specification ntshiab epoxy daim ntawv, cov xim ib txwm yog ntsuab tsaus, uas yog xim ntawm epoxy. Kuj tseem muaj xim daj, feem ntau hais tias daj FR4 hu ua khoom daj, dawb (ntsuab) hu ua cov khoom dawb. FR4 yog kim dua epoxy board, thiab fiberglass board tsis tuaj yeem lees paub tus nqi.
3. Qhov txawv. Cov iav fiber ntau nrog lub suab nqus, suab rwb thaiv tsev, rwb thaiv tsev kub, kev tiv thaiv ib puag ncig, nplaim hluav taws thiab lwm yam ntxwv. FR-4 tseem hu ua fiberglass board; iav fiberboard; FR4 reinforcement phaj; FR-4 epoxy resin phaj; Nplaim retardant rwb thaiv tsev board; Epoxy phaj, FR4 lub teeb phaj. Epoxy iav daim ntaub phaj; Circuit Board Drilling ncoo.
Epoxy board, fiberglass board, molecular qauv muaj active epoxy pawg, thiab ntau yam ntawm curing agent cross-linking reaction to form insoluble, non-melting polymer with a three-way network structure.
