Qaybta Koowaad: Waa maxay Aluminium PCB?
Substrate-ka aluminiumku waa nooc ka mid ah boodhka naxaasta ku xidhan ee ku salaysan birta oo leh hawlkarnimo kuleyl aad u fiican.Guud ahaan, loox hal dhinac ah ayaa ka kooban saddex lakab: lakabka wareegga (foil naxaas ah), lakabka dahaadhka, iyo lakabka saldhigga birta.Codsiyada dhamaadka-sare, waxaa sidoo kale jira naqshado laba-dhinac leh oo leh qaab-dhismeedka lakabka wareegga, lakabka daboolka, saldhigga aluminium, lakabka daboolka, iyo lakabka wareegga.Tiro yar oo codsiyo ah ayaa ku lug leh looxyo lakabyo badan, kuwaas oo lagu abuuri karo isku xidhka looxyada lakabyada badan ee caadiga ah oo leh lakabyo dahaaran iyo saldhigyo aluminium ah.
Substrate aluminium oo hal dhinac ah: Waxa uu ka kooban yahay hal lakab oo ah lakabka hannaan-wadareedka, walxaha dahaadhka ah, iyo saxan aluminium (substrate).
Substrate aluminium laba-geesood leh: Waxay ku lug leedahay laba lakab oo lakabyo qaabaysan, walxo dahaadh ah, iyo saxan aluminium ah (substrate) oo la is dulsaaray.
Looxa wareegga aluminium ee daabacan ee badan: Waa loox wareeg ah oo daabacan oo lagu sameeyay laminating oo isku xidhaya saddex ama in ka badan oo lakabyada qaab-samaynta, walxaha dahaarka, iyo saxan aluminium (substrate) wada jir ah.
Waxaa loo qaybiyaa hababka daaweynta dusha:
Loox-dahab ah (dahab dhuuban kiimiko ah, dahab qaro weyn oo kiimiko ah, dahaadh dahab ah oo la xushay)
Qaybta Labaad: Mabaadi'da Shaqada ee Substrate Aluminium
Qalabka korontada ayaa dusha sare ku dhejisan lakabka wareegga.Kulaylka ay soo saaraan aaladaha inta lagu jiro hawlgalka ayaa si degdeg ah loo dhex maraa lakabka insulating ilaa lakabka saldhigga birta ah, ka dibna ka saara kulaylka, gaaritaanka kulaylka qalabka.
Marka la barbardhigo FR-4-dhaqameedka, aluminium substrates waxay yareyn karaan caabbinta kulaylka, iyaga oo ka dhigaya kuwa ugu fiican ee kulaylka.Marka la barbar dhigo wareegyada dhoobada dhumuc weyn leh, waxay sidoo kale leeyihiin sifooyin farsamo oo heersare ah.
Intaa waxaa dheer, substrate-yada aluminiumku waxay leeyihiin faa'iidooyinka soo socda:
- U hoggaansanaanta shuruudaha RoHs
La qabsiga ka wanaagsan ee hababka SMT
- Maareynta wax ku oolka ah ee fidinta kulaylka ee naqshadeynta wareegga si loo yareeyo heerkulka hawlgalka moduleka, loo kordhiyo cimriga, kor loogu qaado cufnaanta awoodda iyo isku halaynta
- Dhimista isku-ururinta weelasha kulaylka iyo qalabka kale, oo ay ku jiraan agabka isdhexgalka kulaylka, taasoo keentay mugga badeecada yar iyo kharashyada qalabka iyo qalabka hoose, iyo isku dhafka ugu fiican ee korantada iyo wareegyada xakamaynta
- Beddelka substrate-ka dhoobada jilicsan ee sii wanaajinta cimri dhererka farsamada
Qaybta Saddexaad: Halabuurka Aluminium Substrates
1. Lakabka Wareegga
Lakabka wareegga (sida caadiga ah iyadoo la adeegsanayo foil naxaas ah oo elektrolytic ah) ayaa loo xardhay si loo sameeyo wareegyo daabacan, oo loo isticmaalo isku xirka qaybaha iyo isku xirka.Marka la barbar dhigo FR-4-dhaqameedka, oo leh dhumuc isku mid ah iyo ballaca xariiqda, substrate-yada aluminiumku waxay qaadi karaan qulqulo sare.
2. Lakabka dahaadhka ah
Lakabka dahaadhka ah waa tignoolajiyada muhiimka ah ee aluminium ka samaysan, oo u adeegta ugu horrayn ku-xidhka, dahaadhka, iyo kulaylka.Lakabka dahaarka ee aluminium substrates ayaa ah xannibaadda kulaylka ugu muhiimsan ee qaab-dhismeedka moduleka awoodda.Wanaajinta kulaylka kuleyliyaha ee lakabka dahaadhka ah ayaa fududeynaya fidinta kulaylka soo baxa inta lagu jiro hawlgalka qalabka, taasoo horseedaysa hoos u dhaca heerkulka hawlgalka, korodhka culeyska moduleka, cabbirka hoos u dhaca, cimriga dheer, iyo soo saarista koronto sare.
3. Lakabka Saldhigga Birta
Doorashada birta ee saldhigga birta dahaarka waxay ku xiran tahay tixgalin dhamaystiran oo ah arrimo ay ka mid yihiin isugeynta saldhigga birta ee ballaarinta kulaylka, dhaqdhaqaaqa kulaylka, xoogga, qallafsanaanta, miisaanka, xaaladda dusha sare, iyo qiimaha.
Qaybta Afraad: Sababaha Doorashada Aluminium Substrates
1. Kulaylka oo kala baxa
Looxyo badan oo laba-dhinac ah iyo lakabyo badan ayaa leh cufnaan sare iyo awood, taas oo ka dhigaysa kala daadinta kulaylka mid adag.Alaabta substrate-ka caadiga ah sida FR4 iyo CEM3 waa kiriyeyaasha kulaylka liidata waxayna leeyihiin dahaar iskudhaf ah, taasoo keenta kulayl aan ku filnayn.Substrate-yada aluminiumku waxay xalliyaan arrintan kulaylka.
2. Balaadhinta kulaylka
Balaadhinta kulaylka iyo foosha ayaa ka mid ah agabka, walxaha kala duwanina waxay leeyihiin iskudhafyo kala duwan oo balaadhinta kulaylka.Looxyada daabacan ee aluminium-ku-saleysan waxay si wax ku ool ah wax uga qabtaan arrimaha kuleylka kuleylka, fududeynaya dhibaatada ballaarinta kulaylka agabka kala duwan ee qaybaha guddiga, hagaajinta guud ahaan adkeysiga iyo kalsoonida, gaar ahaan codsiyada SMT (Surface Mount Technology).
3. Deganaanshiyaha cabbirka
Looxyada daabacan ee aluminium-ku-saleysan ayaa si gaar ah u xasiloon marka loo eego cabbirrada marka loo eego looxyada daabacan ee dahaaran.Isbeddelka cabbirka ee looxyada daabacan ee aluminium-ku-saleysan ama looxyada xudunta u ah aluminium, kuleyl laga bilaabo 30 ° C ilaa 140-150 ° C, waa 2.5-3.0%.
4. Sababaha kale
Aluminium-ku-salaysan looxyada daabacan waxay leeyihiin saameyn difaac ah, beddelaan substrates dhoobada jilicsan, waxay ku habboon yihiin tiknoolajiyada korka ee dusha sare, waxay yareeyaan aagga waxtarka leh ee looxyada daabacan, beddelaan qaybaha sida weelka kulaylka si kor loogu qaado caabbinta kulaylka alaabta iyo guryaha jirka, iyo hoos u dhigista kharashka wax soo saarka iyo shaqada.
