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 laminate, ngokutsho abasebenzisi ezahlukeneyo, ishishini libizwa ngokubanzi: FR-4 Epoxy Glass insulation ibhodi, epoxy ibhodi, brominated epoxy ibhodi, FR-4, Glass fiberboard, FR-4 eyomeleziweyo ibhodi, FPC eyomeleziweyo ibhodi, bhetyebhetye ibhodi yesekethe eqiniswe ibhodi, FR-4 epoxy board epoxy, FR-4 epoxy board ibhodi, FR-4 glass fiberboard, epoxy glass ilaphu ibhodi, epoxy glass ilaphu laminated ibhodi, ibhodi yesekethe sokomba pad.

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.
