Qalabka elektaroonigga ah, xaddi kuleyl ah ayaa la soo saaraa inta lagu jiro hawlgalka, si heerkulka gudaha ee qalabku si degdeg ah u kordho.Haddii kulaylka aan la daadin wakhtiga, qalabku wuu sii wadi doonaa inuu kululeeyo, qalabkuna wuu ku guuldareysan doonaa sababtoo ah kulaylka.Kalsoonida qalabka elektaroonigga ah Waxqabadku wuu yaraan doonaa.

Sidaa darteed, aad bay muhiim u tahay in lagu sameeyo daawaynta kulaylka wanaagsan ee guddiga wareegga.Kuleylku waa qayb aad u muhiim ah, marka waa maxay farsamada kulaylka ee guddiga wareegga PCB, aynu hoos uga wada hadalno.

Kulaylka kulaylka iyada oo loo marayo looxa PCB laftiisa Looxyada PCB-ga ee hadda sida weyn loo isticmaalo waa maro dhalada ah oo ka samaysan naxaasta/epoxy ama maro dhalada ah oo resin ah, iyo qadar yar oo waraaqo ah oo naxaas ah ayaa la isticmaalaa.

Inkasta oo substrate-yadani ay leeyihiin sifooyin koronto oo heer sare ah iyo sifooyin wax-qabad, waxay leeyihiin kulayl xumo.Sida habka kuleylka kulaylka ee qaybaha kululaynta sare, waa wax aan macquul aheyn in laga filayo kulaylka PCB laftiisa si uu u sameeyo kulayl, laakiin si uu u kala saaro kuleylka dusha sare ee qaybta hawada ku wareegsan.

Si kastaba ha noqotee, sida alaabada elektiroonigga ah ay soo galeen xilligii miniaturization ee qaybaha, dhejinta cufnaanta sare, iyo kulaylka sare ee kuleylka, kuma filna in lagu tiirsanaado dusha sare ee qayb leh meel aad u yar si ay u daadiso kuleylka.

Isla mar ahaantaana, iyadoo ay ugu wacan tahay isticmaalka ballaaran ee qaybaha buurta dusha sare sida QFP iyo BGA, kulaylka ay abuuraan qaybaha ayaa loo wareejiyaa guddiga PCB qadar badan.Sidaa darteed, habka ugu wanaagsan ee lagu xallin karo kulaylka kuleylku waa in la hagaajiyo awoodda kulaylka PCB lafteeda taas oo si toos ah ula xiriirta

▼Kuleyl iyada oo loo marayo walxaha kuleyliyaha.La qabtay ama la shiday.

▼ Kulaylka xagga hoose waa kulayl Via

Soo bandhigida naxaasta ee dhabarka IC waxay yaraynaysaa caabbinta kulaylka ee u dhexeeya naxaasta iyo hawada

Qaabaynta PCB
Qalabka xasaasiga ah ee kulaylka ayaa la dhigayaa aagga dabaysha qabow.

Qalabka lagu ogaanayo heerkulka waxaa la dhigayaa meesha ugu kulul.

Aaladaha ku jira isla looxa daabacan waa in loo habeeyaa sida ugu fog ee suurtogalka ah iyadoo loo eegayo qiimaha kalooriyada iyo heerka kala daadinta kulaylka.Aaladaha leh qiime calorific yar ama caabbinta kulaylka liidata (sida transistor-yada yaryar, wareegyada isku dhafan ee cabbirka yar, capacitors electrolytic, iwm) waa in lagu dhejiyaa socodka hawada qaboojinta.Qulqulka ugu sarreeya (halka laga soo galo), aaladaha leh kulayl weyn ama caabbinta kulaylka (sida transistor-ka korantada, wareegyada isku dhafan ee baaxadda weyn, iwm) ayaa la dhigayaa meesha ugu hooseysa ee socodka hawada qaboojinta.

Jihada toosan, qalabka awoodda sare leh ayaa la dhigayaa meel u dhow cidhifka guddiga daabacan ee suurtogalka ah si loo gaabiyo jidka kulaylka;jihada toosan, aaladaha awooda sare leh ayaa la dhigayaa meel u dhow meesha ugu sareysa ee looxa daabacan sida ugu macquulsan si loo yareeyo saameynta aaladahaan heerkulka aaladaha kale.

Kala-baxa kulaylka ee looxa daabacan ee qalabku wuxuu inta badan ku tiirsan yahay socodka hawada, markaa dariiqa socodka hawada waa in la daraaseeyaa inta lagu jiro naqshadeynta, iyo qalabka ama guddiga wareegga daabacan waa in si macquul ah loo habeeyaa.

Marka hawadu socoto, had iyo jeer waxay u egtahay inay ku qulqulayso meelaha iska caabbinta hooseeya, markaa marka la isku hagaajinayo aaladaha sabuuradda wareegga daabacan, iska ilaali inaad ka tagto hawo weyn meel gaar ah.Habaynta looxyada wareegyada daabacan ee badan ee mashiinka oo dhan waa in sidoo kale fiiro gaar ah u yeeshaan dhibaatada isku midka ah.

Qalabka heerkulka xasaasiga ah ayaa si fiican loo dhigaa aagga heerkulka ugu hooseeya (sida qaybta hoose ee qalabka).Waligaa si toos ah ha u dul dhigin qalabka kuleyliyaha.Way fiicantahay in lagu dhufto aalado badan diyaaradda jiifka ah.

Aaladaha leh isticmaalka tamarta ugu sarreeya iyo kuleyliyaha ayaa lagu habeeyaa meel u dhow meesha ugu fiican ee kuleylka kuleylka.Ha dhigin qalabka kuleyliyaha sare geesaha iyo cidhifyada looxa daabacan, ilaa meel u dhow kulaylka lagu hagaajiyo mooyee.

Markaad naqshadaynayso iska caabiyaha awoodda, dooro qalab weyn sida ugu badan ee suurtogalka ah, oo ka dhig meel ku filan oo loogu talagalay kulaylka marka la hagaajinayo qaabka looxa daabacan.
