I-FR-4 yikhowudi yebakala lezinto ezichasene nomlilo, oku kuthetha ukuba inkcazo yezinto eziphathekayo kufuneka ikwazi ukucima ngokwayo emva kokutshisa.Ayilogama lezinto eziphathekayo, kodwa ibakala lezinto eziphathekayo.Ngoko ke, iibhodi zeesekethe ze-PCB ngokubanzi, Kukho iintlobo ezininzi zezinto ze-FR-4 ezisetyenzisiweyo, kodwa uninzi lwazo zizinto ezidibeneyo ezenziwe nge-Tera-Function epoxy resin ene-filler kunye ne-glass fiber.

FR-4 epoxy glass ilaphu ilaphu, ngokutsho kubasebenzisi ezahlukeneyo, ishishini libizwa ngokubanzi: FR-4 Epoxy Glass insulation board, epoxy board, brominated epoxy board, FR-4, Glass fiberboard, FR-4 eyomeleziweyo ibhodi, FPC eyomeleziweyo ibhodi , ibhodi yesekethe eguquguqukayo ibhodi eyomeleziweyo, ibhodi ye-epoxy ye-FR-4, ibhodi yokugquma i-flame-retardant, ibhodi ye-FR-4 elaminethiweyo, i-FR-4 yeglasi ye-fiberboard, ibhodi ye-epoxy yeglasi yelaphu, i-epoxy yeglasi yelaphu ibhodi elaminethiweyo, ibhodi yesekethe yokugaya ibhodi.

Igama elithi FR4 livela kwinkqubo yokuhlela ye-NEMA apho i-'FR' imele 'isithinteli somlilo', sithobela umgangatho we-UL94V-0.Ukhetho lwe-FR4 lulandelwa yi-TG130.I-TG ibhekisela kwiqondo lokushisa kweglasi yenguqu - iqondo lokushisa apho izinto eziqiniswe ngeglasi ziya kuqala ukonakala kwaye zithambe.Kwiibhodi eziqhelekileyo ze-Fusion eli xabiso li-130 ° C, elingaphezu kokwaneleyo kwizicelo ezininzi.Izinto ezikhethekileyo ze-TG eziPhezulu ziyakwazi ukumelana namaqondo okushisa e-170 - 180 ° C, njengezinto zethu ze-3250.I-FR-5, i-G11 inokumelana nokushisa kwe-155 ° C.

Uninzi lwe-FR4 laminates lutyala ukuxhathisa idangatye kumxholo wayo we-bromine, i-halogen engasebenziyo esetyenziswa rhoqo kumashishini ngenxa yeempawu zayo zokunciphisa amadangatye.Oku kunika izixhobo ze-FR4 iinzuzo ezicacileyo njengempahla ye-PCB yesitokhwe ngokwemiqathango yokhuseleko lomlilo ngelixa ebaleni.Kukwaqinisekisa kancinci ukuba izakhono zakho zokuthengisela azikho kumgangatho.

Nangona kunjalo, i-bromine yi-halogen eyimichiza eyityhefu kakhulu ekhutshwa kwindawo xa i-material itshiswa.Kwanemali encinane yanele ukwenza ingozi enkulu ebantwini okanye ekufeni.Ukunciphisa ukusetyenziswa kwezinto ezinobungozi ezinjalo kwiimveliso zethu zemihla ngemihla, i-halogen-free FR4 laminates ifumaneka ngokulula.

Kutshanje siye savelisa amaphepha amhlophe namnyama e-halogen-free FR4 epoxy glassfiber laminate sheets, ngoku isetyenziswa njengebhodi eqinisiweyo yeFPC kwi-iphone, ukufudumeza amaphepha, njalo njalo.
