Ukwethulwa kwezinto ze-FR4

I-FR ku-FR4 imele i-flame retardant, futhi inombolo yesi-4 ihlukanisa izinto ezibonakalayo kwezinye izinto zalesi sigaba.I-FR4 iyi-fiber yengilazi eqiniswe i-epoxy laminate ebukeka njengeshidi lendwangu elilukiwe elincanyana.Igama elithi FR4 liphinde limelele ibanga elisetshenziselwa ukwenza laminates.Isakhiwo se-fiberglass sinikeza ukuzinza kwesakhiwo sezinto ezibonakalayo.I-fiber yengilazi imbozwe nge-epoxy e-flame retardant.Lokhu kunikeza ukuqina kwempahla kanye nezakhiwo eziqinile zemishini.Zonke lezi zici zenza ibhodi lesekethe eliphrintiwe le-FR4 lidume kakhulu phakathi kwabakhiqizi bezinkontileka zikagesi.

Ibhodi lesekethe eliphrintiwe le-FR4 liphinde lidume ngenxa yalezi zizathu ezilandelayo:

I-FR4 yinto ebiza kancane.

I-1, inamandla aphezulu e-dielectric, afaka isandla ekusebenzeni kwawo kokufakwa kukagesi.

2, Impahla inenani eliphezulu lamandla nesisindo futhi inesisindo esincane.

I-3, ifaka umswakama futhi inezinga lokushisa elilinganiselwe.

I-4, Impahla inempahla enhle yokulahla ugesi.

I-5, i-FR4 ayimumbi amanzi, ngakho ilungele zonke izinhlobo zezicelo ze-Marine PCB.

6, izinto zokwakha ziphuzi kuya kokuluhlaza okotshani, zilungele noma yisiphi isicelo.Zonke lezi zici ziyenza ifaneleke ezindaweni ezihlukahlukene.

Ihlelwa kanjani i-FR4 kumabhodi esekethe aphrintiwe we-FR4?I-FR4 isebenza njengesisekelo sanoma iyiphi i-PCB.Impahla i-laminated nge-copper foil.Sebenzisa ukushisa nokunamathela ku-laminate.Ucwecwe lwe-Copper lungasetshenziswa ukugcwalisa izinto ezivela ohlangothini olulodwa noma zombili.
