PCB-ga Aluminiumka

Iyadoo si degdeg ah loo horumarinayo aaladaha elektaroonigga ah ee ku wajahan yaraynta, awoodda sare, iyo cufnaanta sare, kala-baxa kulaylka wareegga ayaa noqday qodob muhiim ah oo xaddidaya horumarinta waxqabadka qalabka iyo kordhinta cimriga. Laminates-ka muraayadaha galaaska ee FR-4 ee dhaqameed waxay leeyihiin faa'iidooyin waxqabadka dahaarka iyo kharashka laakiin waxay leeyihiin awoodo kala-baxa kulaylka oo daciif ah, kuwaas oo ay adag tahay in la daboolo shuruudaha kala-baxa kulaylka ee qaybaha elektaroonigga ah ee awoodda sare leh. Marka laga soo tago tan, PCB-ga Aluminiumka, oo leh waxqabadkeeda kulaylka ee aadka u fiican, xoog farsamo oo wanaagsan, iyo astaamo koronto oo deggan, ayaa si tartiib tartiib ah u noqotay side wareeg oo muhiim ah oo ku yaal meelaha sida nalalka LED-ka, elektaroonigga baabuurta, iyo modules-ka korontada, taasoo siinaysa taageero muhiim ah oo loogu talagalay casriyeynta tignoolajiyada ee warshadaha elektaroonigga.

1. Fikradda Aasaasiga ah iyo Qaab-dhismeedka Aluminium PCB

Aluminium PCB waa guddi wareeg ah oo ku salaysan bir oo leh aluminium dahaadh ah oo ah agabka salka, oo ka tirsan nooc ka mid ah laminate-ka naxaasta ah ee ku salaysan birta. Si ka duwan PCB-ga dhaqameed, waxay si dhow isugu daraysaa lakabka wareegga birta iyo lakabka wareegga foil-ka naxaasta iyada oo loo marayo lakab gaar ah oo dahaadh ah iyo kan kulaylka gudbiya, kaas oo aan kaliya haysan faa'iidada kala-baxa kulaylka ee walxaha salka birta ah laakiin sidoo kale leh shaqada isku xirka korantada ee guddiga wareegga daabacan. Qaab-dhismeedkiisa caadiga ah wuxuu ka kooban yahay saddex lakab, mid walbana wuxuu leeyahay qayb cad oo shaqada ah iyo saameyn isku-dhafan:

Lakabka Saldhigga Birta ah: Lakabka taageerada asaasiga ah iyo kala-baxa kulaylka, badanaa wuxuu isticmaalaa daawaha aluminiumka oo leh nadiifnimo ka badan 90% (sida moodooyinka 1060, 5052, 6061). Daawaha aluminiumka 1060 wuxuu leeyahay gudbin kuleyl oo aad u fiican iyo qaab-dhismeed, oo ku habboon xaaladaha leh shuruudaha kala-baxa kulaylka oo sarreeya; Daawaha aluminiumka 5052 wuxuu leeyahay xoog sare iyo iska caabin wanaagsan oo daxaleed, oo badanaa loo isticmaalo qalabka elektaroonigga baabuurta ee leh jawi adag; Daawaha aluminiumka 6061 wuxuu dheellitiraa xoogga iyo la-socodka kulaylka, oo ku habboon wareegyada saxda ah ee u baahan farsamaynta farsamada.
Lakabka dahaarka iyo kan kulaylka gudbiya (Lakabka Dielectric): Lakabka dhexe ee muhiimka ah ee isku xira agabka salka birta iyo bir-bireedka naxaasta ah, iyo sidoo kale xudunta tignoolajiyada PCB-ga aluminiumka ah. Lakabkani wuxuu u baahan yahay inuu lahaado dahaadh sare, iska caabin kuleyl oo hooseeya, iyo xoog isku xidhnaan oo wanaagsan isla waqtigaas. Badanaa wuxuu ka kooban yahay walxo polymer ah sida epoxy resin iyo polyimide oo lagu daray buuxinta dhoobada (sida aluminium oxide iyo aluminium nitride). Ku darista buuxinta dhoobada ah waxay si weyn u hagaajin kartaa gudbinta kulaylka. Waqtigan xaadirka ah, gudbinta kulaylka ee lakabka dahaarka iyo gudbinta kulaylka ee PCB-yada aluminiumka ee caadiga ah waxay u dhaxaysaa 1.0-5.0 W/(m·K), qaar ka mid ah alaabada heerka sare ah waxay gaari karaan in ka badan 10 W/(m·K).
Lakabka Wareegga Birta Naxaasta ahLakabka shaqada ee lagu xaqiijinayo isku xirka korantada, iyadoo la adeegsanayo bir naxaas elektaroonik ah ama bir naxaas ah oo la duubay, oo dhumucdiisuna tahay 1oz (35μm), 2oz (70μm) ama ka dhumuc weyn, oo lagu xushay shuruudaha culeyska hadda ee wareegga. Bir naxaastu waxay samaysaa qaabab wareeg oo adag iyada oo loo marayo habka qorista si loo bixiyo waddooyin hadda jira oo loogu talagalay qaybaha elektaroonigga ah.

2. Astaamaha Aasaasiga ah iyo Faa'iidooyinka Aluminium PCB

Sababta ay PCB-ga aluminiumku u beddeli karo PCB-ga dhaqameed ee meelo badan waxay ku jirtaa isku-darka waxqabadka gaarka ah, gaar ahaan muujinta faa'iidooyin muhiim ah oo ku saabsan kala-baxa kulaylka, farsamada, korontada iyo dhinacyo kale:

Kala-baxa Kulaylka oo Waxtar leh, Hagaajinta Kalsoonida Qalabka

Kala firdhinta kulaylka waa faa'iidada ugu weyn ee PCB-ga aluminiumka. Laydhka kulaylka ee substrate-ka dhaqameed ee FR-4 waa 0.2-0.3 W/(m·K), halka laydhka kulaylka ee walaxda salka birta ee PCB-ga aluminiumka uu gaari karo 100-200 W/(m·K). Marka lagu daro lakabka dahaarka kulaylka sare, waxay si dhakhso ah u qaadi kartaa kulaylka ay soo saaraan qaybaha elektaroonigga ah (sida jajabyada LED, tuubooyinka korontada) substrate-ka birta, ka dibna waxay ku faafin kartaa hawada iyada oo loo marayo saxannada kulaylka ama guryaha. Xogta tijaabada ah waxay muujinaysaa in xaalad isku mid ah oo koronto ah, heerkulka isgoyska ee nalalka LED-ka ee isticmaalaya PCB-ga aluminiumka ah la dhimi karo 20-30℃ marka la barbar dhigo substrate-ka FR-4, cimriga LED-kana waa la labanlaabmi karaa hoos u dhac kasta oo 10℃ ah heerkulka isgoyska, taasoo si weyn u hagaajinaysa isku halaynta muddada dheer ee qalabka.

Waxqabadka Farsamada ee Wanaagsan, Iska caabinta Isbeddelka iyo Saamaynta

Agabka saldhigga ah ee aluminiumku wuxuu leeyahay xoog iyo adkeysi sare. Marka la barbardhigo substrate-ka dhaqameed ee FR-4 (kaas oo ah mid jilicsan oo si fudud loo jabin karo), PCB-ga aluminiumku ma fududa in la beddelo ama la dhaawaco jawi adag sida gariirka, saameynta, iyo isbeddelka heerkulka. Sifadan ayaa ka dhigaysa mid si gaar ah ugu habboon xaaladaha u baahan xasillooni farsamo oo sare sida qalabka elektaroonigga ah ee baabuurta (sida modules-ka xakamaynta ee qaybta matoorka) iyo qalabka warshadaha (sida beddelayaasha soo noqnoqda, darawallada servo), kuwaas oo si wax ku ool ah u yareyn kara xiriirka liita ama cilladaha wareegga gaaban ee ay keento isbeddelka wareegga.

Dahaarka Korontada oo aad u Fiican, Hubinta Badbaadada Isticmaalka

Lakabka dahaarka iyo kan kulaylka gudbiya wuxuu qaataa walxo dahaar polymer tayo sare leh, oo leh danab jab ah oo ah 20-50kV/mm, kaas oo si wax ku ool ah u kala sooci kara wareegga birta ee naxaasta ah iyo walxaha salka birta ah isla markaana ka hortagi kara shilalka daadashada ama burburka. Isla mar ahaantaana, lakabkani wuxuu leeyahay joogto dielectric hooseeya (badanaa 3.0-4.5@1MHz), oo leh lumis yar oo gudbinta calaamadaha ah, oo ku habboon xaaladaha wareegga soo noqnoqda sare.

Fududeynta Naqshadeynta Kala-baxa Kuleylka, Yaraynta Qiimaha Guud

Iyada oo ay ugu wacan tahay awoodda wanaagsan ee kala-baxa kulaylka ee PCB-ga aluminiumka laftiisa, qaybaha kala-baxa kulaylka dhaqameed sida saxannada kulaylka iyo koollada gudbinta kulaylka waa la dhimi karaa ama laga tagi karaa, taasoo fududaynaysa naqshadda qaab-dhismeedka qalabka iyo yaraynta kharashyada agabka iyo isu-imaatinka. Intaa waxaa dheer, isku-darka ballaarinta kulaylka ee PCB-ga aluminiumka ayaa si aad ah ula jaanqaadaya guriga birta iyo saxanka kulaylka, taas oo yarayn karta dhibaatada dildilaaca kala-goysyada alxanka ee ay keento cadaadiska kulaylka oo hoos u dhigi karta kharashka dayactirka dambe.

Ilaalinta Deegaanka iyo Dib-u-warshadaynta, U hoggaansanaanta Isbeddellada Cagaaran

Qalabka salka birta ah ee PCB-ga aluminiumka ah ayaa 100% dib loo warshadeyn karaa, lakabka dahaarka lehna waa walxo polymer ah oo deegaanka u fiican, kaas oo waafaqsan heerarka ilaalinta deegaanka sida RoHS. Marka la eego u doodista caalamiga ah ee wax soo saarka cagaaran, astaamaha ilaalinta deegaanka ee PCB-ga aluminiumka ayaa ka dhigaya doorashada koowaad ee shirkadaha elektaroonigga ah si ay u gaaraan horumar waara.

3. Noocyada ugu Muhiimsan iyo Xaaladaha Codsiga ee PCB-ga Aluminium
