Ukuqaliswa kwezixhobo zeFR4

I-FR kwi-FR4 imele i-flame retardant, kunye nenombolo ye-4 iyahlula izinto ezivela kwezinye izinto ezikulo klasi.I-FR4 yi-fiber yeglasi eqiniswe i-epoxy laminate ekhangeleka njengephepha elincinci elilukiweyo.Igama elithi FR4 likwamele ibakala elisetyenziselwa ukwenza ezi laminates.Isakhiwo se-fiberglass sibonelela ngokuzinza kwesakhiwo kwizinto eziphathekayo.Ifiber yeglasi yogqunywe yi-epoxy ye-flame retardant.Oku kunika ukuqina kwezinto eziphathekayo kunye neempawu ezinamandla zoomatshini.Zonke ezi mpawu zenza ibhodi yesekethe eprintiweyo yeFR4 idume kakhulu phakathi kwabavelisi bekhontrakthi ye-elektroniki.

Ibhodi yesekethe eprintiweyo yeFR4 ikwadumile ngezi zizathu zilandelayo:

I-FR4 yinto enexabiso eliphantsi.

I-1, inamandla aphezulu e-dielectric, enegalelo ekusebenzeni kwayo kombane.

2, Izinto eziphathekayo zinomlinganiselo ophezulu wamandla-to-ubunzima kwaye zilula ngobunzima.

I-3, ibubungqina bokufuma kwaye inobushushu obuhambelanayo.

I-4, Izinto eziphathekayo zinepropati efanelekileyo yokutshatyalaliswa kombane.

I-5, i-FR4 ayifuni amanzi, ngoko ifanelekile kuzo zonke iintlobo zezicelo ze-PCB yaseLwandle.

I-6, izixhobo zityheli ukuya kuluhlaza okhanyayo, zilungele nasiphi na isicelo.Zonke ezi mpawu zenza ukuba ifaneleke kwiindawo ezahlukeneyo.

Ihlelwa njani iFR4 kwiibhodi zesekethe eziprintiweyo zeFR4?I-FR4 isebenza njengesiseko sayo nayiphi na iPCB.Izinto eziphathekayo zi-laminated nge-foil yobhedu.Sebenzisa ubushushu kunye ne-adhesive kwi-laminate.I-foil yobhedu ingasetyenziselwa ukuhlamba izinto ezivela kwelinye okanye kumacala omabini.
