Kaalay oo wax ka baro fr-4 laminate maro galaas epoxy

Qof walba ha ogaado wax ku saabsan fr-4 laminate maro galaas epoxy! Qof walba waa inuu yaqaanaa tan! FR-4 waa magaca koodhka darajada maaddada u adkaysta dabka. Waxay u taagan tahay qeexitaan maadi ah oo maaddada cusbi waa inay awood u leedahay inay iskeed u bakhtiiso dabka gubashada ka dib. Ma aha magac maaddi ah, ee waa darajo maaddi ah. Sidaa darteed, wareegga guud ee hadda jira Waxaa jira noocyo badan oo ah qalabka fasalka FR-4 oo loo isticmaalo sabuuradda, laakiin badidoodu waa qalab isku jira oo ka samaysan waxa loogu yeero resin epoxy oo afar-shaqaynaya, filler iyo fiber galaas.

FR-4 maro galaas epoxy laminate, sida laga soo xigtay isticmaalka kala duwan, warshadaha guud ahaan waxaa loogu yeeraa: guddiga dahaarka leh, guddiga epoxy, guddiga cusbi epoxy, guddiga epoxy cusbi brominated, FR-4, guddiga fiberglass, guddiga fiberglass, guddiga dahaarka dab-retardant, Guddiga FR-4 laminated, board epoxy, FR-4 board light, FR-4 board fiberglass, board maro galaxy epoxy, laminate galaxy epoxy glass, board circuit qodista. Tilmaamaha farsamooyinka ugu waaweyn iyo codsiyada: waxqabadka dahaarka korantada ee deggan, fidinta wanaagsan, dusha siman, godad lahayn, heerarka dulqaadka dhumucda, oo ku habboon alaabooyinka dahaarka elektiroonigga ah ee waxqabadka sarreeya.

Aan marka hore ka hadlo sifooyinkiisa: FR-4 substrate maro fiber galaxy galaxy waa nooc ka mid ah substrate-ka oo u adeegsada cusbi epoxy ah sida koolo iyo maro fiber galaas fasalka elektiroonigga ah sida walax xoojinaysa. Xaashida isku xidhka iyo dahaarka dahaarka ah ee khafiifka ah ee dhuuban ee khafiifka ah ayaa ah substrates muhiim u ah samaynta boodhadhka wareegyada badan ee daabacan.

Aynu ka hadalno waxqabadkeeda: Guryaha farsamada, xasilloonida cabbirka, iska caabbinta saamaynta, iyo iska -caabbinta qoyaanka ee marada maro -galaaska galaaska epoxy -ga ayaa ka sarreeya tan warqad -hoosaadka. Wax -qabadkiisa korontadu aad buu u fiican yahay, heerkulka shaqaduna aad buu u sarreeyaa, wax -qabadkiisuna wax yar bay saamaynaysaa bay’adu. Marka la eego farsamaynta farsamaynta, waxay leedahay faa’iidooyin aad u weyn marka la barbar dhigo waxyaabaha kale ee ka samaysan maro fiber galaas. Badeecada noocan ah waxaa inta badan loo adeegsadaa PCB-ga laba-gees leh, cadadkuna waa weyn yahay.

Ugu dambayn, ka hadal codsigiisa: substrate maro fiber galaas galaxy, nooca wax-soo-saarka ugu badan ee la isticmaalo waa FR-4. Sanadihii la soo dhaafay, iyada oo ay ugu wacan tahay horumarinta tikniyoolajiyadda kordhinta alaabada elektiroonigga ah iyo teknolojiyadda PCB, alaabooyinka FR-4 oo leh Tg sare ayaa soo muuqday.
