Substrate-ka aluminium waa xarkaha bir-ku-saleysan oo bir ah oo leh qafis leh oo kululaynta kuleylka wanaagsan. Waa sheyga saxan ee ka samaysan maro galaas elektiroonig ah ama ashyaado kale oo xoojin ah oo leh resin, hal resin, iwm. Kursida Kangxin wuxuu soo bandhigayaa waxqabadka aluminium substrate iyo dawada dusha sare ee qalabka.
Waxqabadka sunta ah ee aluminium
1. Waxqabadka kuleylka kuleylka
Taarikada aluminium-clad-clad-clad-clad-clad ee ku saleysan codka copd-clates waxay leeyihiin waxqabadka kuleylka kuleylka ee aadka u wanaagsan, kaas oo ah astaamaha ugu caansan ee noocan ah saxanka noocan ah. PCB-ga ee laga sameeyay oo keliya kama hor tagi karo heerkulka shaqada ee qaybaha iyo sunta ku dhejisa kor u kaca, laakiin sidoo kale kuleylka korantada leh qaybaha awooda sare, wareejinta korantada waaweyn iyo qaybaha kale ee wareega. Waxaa sidoo kale loo qaybiyaa cufnaanta yar-yar, miisaanka nalka (2.7g / cm3), ka hortagga ogking, iyo qiimaha ka jaban, sidaa darteed waxay noqotay tirada ugu badan ee xaashida coper-ka-salka ku saleysan biraha-salka ku saleysan. Iska caabbinta kuleylka kuleylka ee aluminiumka ee aluminium-ka ah waa 1.10 ℃ / w iyo iska caabbinta kuleylka waa 2.8 ℃ / w, oo si weyn u wanaajinaya murugada hadda ee silig-naxaasta.
2.Maafi waxtarka iyo tayada mashiinnada
Aluminium-Clad oo ku saleysan Counainetes wuxuu leeyahay awood farsamo oo sare iyo adag, kaas oo aad uga fiican resin resin resin-clin-clin-chreempetes iyo ceymiska dhoobada. Waxay garan kartaa soo-saarista looxyada daabaxa ee weyn ee ku daabacan sunta birta, waxayna si gaar ah ugu habboon tahay kor u qaadida qaybo culus oo ku saabsan suntaas. Intaas waxaa sii dheer, substrate-ka aluminium sidoo kale waxay leedahay guri wanaagsan, waana la isu soo ururin karaa oo laga baaraandegi karaa miiska durugsan, iwm.
3.Waxaa xasilloonida cabbirka cabbirka ah
Wixii loogu talagalay shaashadda naxaasta ah ee naxaasta ah, waxaa jira dhibaato ballaarinta kuleylka (xasilloonida cabbir ahaan), gaar ahaan ballaarinta kuleylka ee jihada dhumucda (z-axis) ee guddiga, kaas oo saameeya tayada godad la taaban karo iyo fiilooyinka. Sababta ugu weyn ayaa ah in isku-darka ballaarinta quraanka ah ee taarikada ay ka duwan yihiin, sida naxaasta, iyo in la ballaariyo suuqa toosan ee substrate-ka, taas oo keenaysa in wareegga naxaasta ah iyo godka miinada la jajabiyo. Feejignaanta fidinta toosan ee substrate-ka aluminium waa inta udhaxeysa, waxay aad uga yar tahay substrate-ka guud, waxayna ku dhowdahay isbarbardhiga khaladaadka toosan ee naxaasta, kaas oo u dhigma hubinta tayada iyo isku halaynta wareegga daabacan.
Daweynta dusha sare ee maaddada aluminium
1. Deioil
Dusha sare ee saxanka aluminium waxaa lagu daboolaa lakabka saliida inta lagu gudajiro howsha iyo gaadiidka, waana in la nadiifiyaa ka hor isticmaalka kahor. Mabda 'mabda' waa in la isticmaalo gaaska (daadashada guud ee gaaska) sida dareeraha, kaas oo lagu kala diri karo, ka dibna loo adeegsado wakiilka nadiifinta biyaha si looga saaro wasaqda saliida. Ku mayr dusha sare biyo socda si aad uga dhigto nadiif iyo biyo la'aan biyo.
2. Deganaanshaha
Qeybta aluminium ka dib daaweynta kor ku xusan wali waa dufan aan la xareyn dusha sare. Si aad gabi ahaanba uga saarto, ku qoo saydhowro si xoog leh oo ah hydroxide 50 ° C 5 daqiiqo, ka dibna ku mayr biyo nadiif ah.
3. Alkaline etching. Dusha sare ee saxanka aluminiumka maadaama qalabka salka laga helo ay tahay inay lahaato mid kacsan. Tan iyo markii la eego aluminium ee lakabka aluminium ee dusha sare ee dusha sare labadaba waa walxaha amphoteric, dusha sare ee aluminium saldhigga loo yaqaan 'aluminium' waxaa lagu dhejin karaa aashitada, aaladda aaladda, alkaline ama nidaamka alkaline alkaline. Intaas waxaa sii dheer, walxaha kale iyo waxyaabaha lagu daro waxay u baahan yihiin in lagu daro xalka qulqulka si loo gaaro ujeeddooyinka soo socda.
4. Qiyaasta kiimikada (dillaaca). Sababtoo ah sheyga saldhigga aluminium waxaa ku jira biraha kale ee wasakhda ah, way fududahay in la sameeyo xeryahooda Enorganic ee u hoggaansanaanta dusha sare ee nidaamka ku dhaca, sidaa darteed xeryahooda Inorganic ee laga sameeyay dusha sare waa in la falanqeeyo. Marka loo eego natiijooyinka falanqaynta, diyaarso xallin ku habboon oo ku habboon, oo ku rid aluminium aluminium-ka xalka xalka ah si loo hubiyo waqti cayiman, si dusha sare ee saxanka aluminium uu nadiif yahay oo nadiif yahay.
