Faa'iidada PCB-ga Birta ah:

* Kala firidhida kulaylka - Qaybta Nalalka qaarkood waxay faaftaa inta u dhexeysa 2-5W kuleylka iyo guuldarrooyinku waxay dhacaan marka kuleylka iftiinka uusan si dhakhso leh u baabi'in; soosaarka iftiinka waa la dhimay iyo sidoo kale hoos u dhac marka kuleylka uu weli fadhiisto xirmada LED-ka. Ujeeddada PCB-ga aasaasiga ah waa in si hufan looga baabi'iyo kuleylka dhammaan maadooyinka IC-da (ma aha oo kaliya iftiinka). Saldhigga aluminium iyo lakabka dielectric kuleylka kuleylka kuleylka ah wuxuu u dhaqmaa sida buundooyinka udhaxeeya IC iyo kululeeyaha. Hal kuleyl oo keliya ayaa si toos ah loogu dhejiyaa saldhigga aluminium iyadoo la tirtirayo baahida loo qabo qaboojiyaha kuleylka badan dusha sare ee qaybaha dusha laga saaray.
* Ballaarinta kuleylka - Aluminium iyo naxaas waxay leeyihiin hor u gaar ah marka loo eego FR4 caadiga ah, kuleylka kuleylka wuxuu noqon karaa 0.8 ~ 3.0 W / cK Qeybta elektarooniga ah iyo in la yareeyo meelaha muhiimka ah sida qaybta birta kuleylka leh.

* Maaddooyinka PCB-ga ee Muhiimka ah iyo dhumucdiisuna - Xuddunta birta waxay noqon kartaa aluminium, naxaas khafiif ah ama naxaas culus ama isku-dar ah alloysyo gaar ah, ama asalka dhoobada ah ee loo yaqaan 'Al2O3 core' (PCB-ga noocan ah ayaa ugu fiican faafinta kuleylka). laakiin caadiyan waa aluminium asaasiga ah PCB. Dhumucda biraha taarikada saldhigga ah ee 'Metal Core PCB' caadi ahaan waa 40 mil - 150 mil, laakiin waxay ku saleysan tahay macaamil codsi kala duwan, taarikada qaro weyn iyo mid khafiif ah ayaa suurtagal ah. Birta Core PCB dhumucda bireed copper waxay noqon kartaa 0.5oz - 6oz.
* Xasiloonida cabbirka - Cabbirka Birta PCB-ga ayaa ka xasilloon waxyaabaha walxaha dahaaran. Isbedelka cabbirka ee 2.5 ~ 3.0% markii Aluminium PCB iyo aluminium aluminium kuleylka laga kululeeyay 30 ℃ ilaa 140 ~ 150 ℃. 
* Faa'iido Leh - PCB-yada Birta Muhiimka ah waxay faa'iido u yeelan karaan inay u adeegsadaan awooddooda isku-darka lakabka polymer dielectric oo leh hagitaan heer-kul sarreeya oo loogu talagalay iska caabinta kuleylka hoose. PCB-yada Birta Muhiimka ah kala firdhinaya kuleylka 8 ilaa 9 jeer ka dhaqso badan FR4 PCBs. MCPCB waxay dahaarisaa kuleylka faafiya, iyadoo ku haysa qaybaha dhaliya kuleylka sida ugu qabow badan ee suurtogalka ah, shaqadan waxay ka adkaan kartaa Fr4 PCB codsi badan oo nalal ah. 

Codsiyada

PCB-ka muhiimka u ah birta ayaa loo adeegsadaa iftiinka LED-ka, korontada, kororka korantada. Waxaan bixinaa MCPCBs Isticmaalka udubdhexaadka aluminium, asaasiga naxaasta, xudunta birta dadka qaar ayaa ugu yeeray IMS PCB. PCB-yada Birta Muhiimka ah waa looxyada maareynta kuleylka ee loo isticmaalo Codsiyada soo saaraya Heat sare. Sida LED-yada, qeybta korontada bixisa, Codka, Motoorka, Wadada Wadada, Awoodda Waajibaadka culus, Tooshka, Nalalka Isboortiga, Gawaarida Gawaarida, Nalka Stage.
