Aluminium-ku-salaysan looxa wareegga waa bir gaar ah oo ku salaysan naxaas-xidhka looxa, Waxay ka kooban tahay lakabka wareegga, lakabka kuleylka kuleylka leh iyo lakabka saldhigga birta. Lakabka wareegga (foil naxaas ah) ayaa sida caadiga ah loo xardhay si loo sameeyo wareeg daabacan, si qaybaha kala duwan ee qaybta ay isugu xiran yihiin midba midka kale. Guud ahaan, lakabka wareegga ayaa looga baahan yahay inuu yeesho awood weyn oo hadda qaada, taas oo ah in la tixgeliyo Isticmaalka foornada naxaasta ah ee dhumucdiisuna waxay leedahay kulaylka kulaylka wanaagsan, korantada korantada iyo waxqabadka mashiinka.

Lakabka dahaarka kulaylka waa tignoolajiyada udub-dhexaadka u ah substrate aluminium PCB. Guud ahaan waxay ka kooban tahay polymers gaar ah oo ay ka buuxaan ceramics gaar ah, conductivity kaamerada ugu badan ee lakabka dahaadhka waa 8W / Mk, iyo kulaylka ee substrate kala soocidda thermoelectric waa 220-350W / mK
Lakabka saldhigga birta waa xubin ka mid ah taageerada substrate aluminium, kaas oo u baahan tayada kulaylka sare, guud ahaan substrate aluminium iyo substrate naxaas ah (substrate naxaas ah ayaa ku siin kara conductivity kaamerada wanaagsan), kaas oo ku haboon qodista, dhinta stamping, saxan gong, V- CUT, iwm. Mashiinnada caadiga ah.
Aluminium-ku-saleysan PCB-ga naxaasta dahaaran waa walxo guddiga wareegga birta ah, kaas oo ka kooban bireed naxaas ah, lakabka kuleylka kuleylka iyo substrate bir ah. Qaab dhismeedkeedu wuxuu u qaybsan yahay saddex lakab:
Lakabka wareegga: Waxay u dhigantaa laminate-ka naxaasta ah ee PCB-ga caadiga ah, dhumucdiisuna waxay tahay 1oz ilaa 10oz.
Lakabka dahaadhka: Waa lakab ka mid ah walxaha dahaadhka kulaylka leh ee leh caabbinta kulaylka hooseeya. Dhumucdiisuna: 0.003 "ilaa 0.006" inch waa tignoolajiyada udub-dhexaadka u ah aluminium-ku-salaysan laminate naxaas ah.
Lakabka Substrate-ka: Waa substrate bir ah, guud ahaan aluminium-ku-saleysan laminate naxaas-ku-saleysan ama naxaas-ku-saleysan laminate.

PCB ku salaysan Copper waa mid aad u sarreeya qiimaha substrate birta, conductivity kaamerada ayaa marar badan ka wanaagsan aluminium PCB ku salaysan iyo birta ku salaysan PCB, ku haboon wareegyada-soo noqnoqda sare iyo meelaha heerkulka sare iyo hooseeyo, qalabka isgaarsiinta iyo qalabka kale ee elektarooniga ah u baahan wanaagsan. kulaylka kala baxa.
Lakabka wareegga korantada ee PCB oo leh awood weyn oo hadda jirta, waa in la isticmaalo foornada naxaasta ka sii dhumuc weyn, guud ahaan 35 microns ilaa 280 microns dhumucdiisuna tahay, xudunta udub dhexaadka walxaha kuleylka ah ee 3 oxidation 2 aluminium iyo budada silikoon iyo resin epoxy buuxiyey halabuurka polymer, kulaylka iska caabin yar, awood viscoelastic wanaagsan, wuxuu leeyahay awoodda gabowga kulaylka, awood u adkeysiga stress farsamo iyo kulaylka.
1, Kulaylka kulaylka ee PCB ku salaysan naxaas waa laba jeer ka aluminium PCB ku salaysan. Markasta oo uu sareeyo heerkulka kulaylka, ayaa sare u kaca waxtarka kulaylka iyo sida ugu fiican ee waxqabadka kulaylka.
2, saldhigga copper waxaa lagu baaraandegi karaa galay godad metallized, iyo saldhigga aluminium ma karo, network of godad metallized waa in ay shabakad isku mid ah, si ay signal uu leeyahay waxqabadka grounding wanaagsan, iyo naxaas laftiisa leeyahay qaab weldable.
3, saldhigga naxaasta ah ee substrate naxaasta ah waxaa lagu dhejin karaa sawiro fiican, ka shaqeynta madaxa, qaybaha si toos ah ayaa loogu dhejin karaa madaxa, si loo gaaro saameyn aad u fiican oo dhulka iyo kuleylka;
4, iyadoo ay ugu wacan tahay kala duwanaanshaha moodeelka laastikada ee naxaasta iyo aluminiumka, dagaalka u dhigma iyo ballaarinta iyo foosha ee substrate naxaasta ayaa ka yarayn doona kan substrate aluminium, iyo waxqabadka guud ayaa aad u xasilloon.
5, iyadoo ay ugu wacan tahay saldhigga naxaasta qaro weyn, naqshadeynta dhexroorka qalabka ugu yar ee qodista waa in uu ahaadaa 0.4mm, kala dheereynta xariiqda iyadoo loo eegayo dhumucda xaashida naxaasta ah ee substrate naxaasta ah si loo go'aamiyo, dhumucdiisuna waxay sii dheer tahay dhumucda birta naxaasta, baahida loo qabo in la hagaajiyo ballaca xariiqdu waa ka sii ballaaran yahay, baahida loo qabo in la hagaajiyo kala fogaanshaha ugu yar ayaa ka weyn.

Codsiyada:
Alaabooyinka waxaa si weyn loogu isticmaalaa cod-weyneyaasha maqalka, amplifiers-ka awoodda, habeynta beddelka, beddelayaasha DC / AC, darawallada mootada, korantada elektiroonigga ah, kontaroolayaasha korantada, modules-yada awoodda sare leh, isgaarsiinta, korontada, elektiroonigga, baabuurta, qalabka caafimaadka, qalabka otomaatiga, Qalabka 3D, qalabka guriga, nalalka iyo beeraha kale.
