Shaki ma qabtaa, muxuu substrate aluminium uga fiican yahay FR-4?
Aluminium pcb wuxuu leeyahay waxqabad wanaagsan oo wax qabad, wuxuu noqon karaa laabasho qabow oo kulul, goynta, qodista iyo hawlaha kale ee farsamaynta, si loo soo saaro noocyo kala duwan oo qaabab iyo cabbir ah guddiga wareegga. Guddiga wareegga FR4 aad bay ugu nugul yihiin dildilaaca, xariifinta iyo dhibaatooyinka kale, wayna adagtahay in la habeeyo. Sidaa darteed, substrate-ka aluminiumka waxaa badanaa loo isticmaalaa alaabada elektiroonigga ah ee waxqabadka sare leh, sida iftiinka LED-ka, qalabka elektiroonigga ah, sahayda korontada iyo meelo kale.
Dabcan, aluminium pcb sidoo kale waxay leedahay faa'iido darrooyin. Sababtoo ah substrate-ka birta ah, qiimaha aluminiumku wuu sarreeyaa, guud ahaanna aad ayuu uga qaalisan yahay FR4. Intaa waxaa dheer, sababtoo ah aluminiumka aluminiumku ma fududa in lagu xiro biinanka qalabka elektiroonigga ah ee guud, daaweyn gaar ah, sida metallization, ayaa loo baahan yahay, taas oo kordhisa qiimaha wax soo saarka. Intaa waxaa dheer, lakabka daboolka ee aluminiumka aluminiumku wuxuu sidoo kale u baahan yahay daaweyn gaar ah si loo hubiyo waxqabadka kuleylka kulaylka iyada oo aan saameyn ku yeelan tayada gudbinta calaamadaha.
Marka lagu daro kala duwanaanshaha qiimaha, waxaa sidoo kale jira farqi u dhexeeya aluminium pcb iyo FR4 marka la eego waxqabadka iyo kala duwanaanta codsiga.
Ugu horreyntii, aluminiumka aluminiumku wuxuu leeyahay waxqabad kuleyl ah oo ka fiican, kaas oo si wax ku ool ah u baabi'in kara kulaylka uu soo saaro guddiga wareegga si degdeg ah. Tani waxay ka dhigaysa substrate aluminium mid aad ugu habboon awoodda sare, naqshadaynta wareegga cufnaanta sare, sida nalalka LED, modules korantada, iwm. naqshadeynta wareegga.
Marka labaad, awoodda qaadista hadda ee substrate aluminium ayaa ka weyn, taas oo ku habboon soo noqnoqoshada sare iyo codsiyada wareegga sare ee hadda jira. Naqshadeynta wareegga awoodda sare, hadda waxay dhalin doontaa kulayl, iyo heerkulka sare ee kuleylka iyo waxqabadka kuleylka wanaagsan ee aluminiumka aluminiumku wuxuu si wax ku ool ah u baabi'in karaa kuleylka, sidaas darteed hubinta kalsoonida iyo xasilloonida wareegga. Awoodda qaadida hadda ee FR4 waa mid yar oo kuma habboona awood sare, naqshadaynta wareegyada soo noqnoqda.
Intaa waxaa dheer, waxqabadka seismic substrate aluminium sidoo kale wuu ka fiican yahay FR4, wuxuu si fiican uga hortagi karaa shoogga farsamada iyo gariirka, sidaas darteed baabuurta, tareenka iyo meelaha kale ee naqshadeynta wareegga elektaroonigga ah, substrate aluminium ayaa sidoo kale si ballaaran loo isticmaalay. Isla mar ahaantaana, substrate-ka aluminiumku wuxuu kaloo leeyahay waxqabadka faragelinta ka-hortagga-electromagnetic-ka ee wanaagsan, kaas oo si wax ku ool ah u ilaalin kara hirarka korantada oo yareeya faragelinta wareegga.
Guud ahaan, aluminium pcb waxay leedahay waxqabad kuleyl ah oo ka fiican, awoodda qaadida hadda, waxqabadka seismic iyo caabbinta faragelinta korantada marka loo eego FR4, waxayna ku habboon tahay naqshadeynta wareegga awoodda sare, cufnaanta sare iyo soo noqnoqda. FR4 waxay ku habboon tahay naqshadaynta wareegga elektiroonigga ah ee guud, sida taleefannada gacanta, laptop-yada iyo alaabada kale ee elektiroonigga ah ee macaamiisha. Qiimaha substrate aluminium guud ahaan wuu sarreeyaa, laakiin naqshadaynta wareegga baahida sare, doorashada substrate aluminium waa tallaabo aad muhiim u ah.
Marka la soo koobo, aluminium pcb iyo FR4 waxay ku habboon yihiin noocyada kala duwan ee codsiyada wareegga waxayna leeyihiin faa'iidooyin iyo faa'iido darrooyinkooda. Markaad dooranayso qalabka wareegga wareegga, waxaa lagama maarmaan ah in la miisaamo arrimo kala duwan iyadoo loo eegayo xaaladaha codsiga gaarka ah iyo shuruudaha si loo doorto qalabka ugu habboon.
