Qalabka elektiroonigga ah, qadar gaar ah oo kuleyl ah ayaa la soo saaray inta lagu gudajiro hawlgalka, si heerkulka gudaha ee qalabka uu si dhakhso ah u kaco. Haddii kuleylka aan la fidin waqtiga, qalabku wuxuu sii wadi doonaa kuleylka, oo aaladda ayaa ku guul darreysan doonta inay kululaato. Ku kalsoonaanta waxqabadka qalabka elektiroonigga ah ayaa yaraanaya.
Sidaa darteed, waxaa muhiim ah in la sameeyo daaweyn kulayl kulayl wanaagsan oo ku saabsan guddiga wareega. Kuleylka kuleylka ee guddiga PCB ee PCB-gu waa qeyb aad muhiim u ah, sidaa darteed waa maxay farsamada kuleylka kuleylka ee guddiga PCB ee wareegga PCB, aan ka wada hadalno hoosta.
Kuleylka kuleylka kululaynta PCB guddiga PCB ee loo yaqaan 'PCB looxyada PCB' ee loo yaqaan 'pcb' pcb clad-ka-buugga / maro-dhalada dharka lagu dhajiyo ama looxyada dhalada phenolic-ka ah, iyo qaddar yar oo looxyo xaashi ah oo ku saleysan xaashiyaha xargaha xargaha.
In kasta oo jiradaasi ay leeyihiin guryo koronto oo aad u wanaagsan iyo guryaha lagu hawlgeliyo, waxay leeyihiin ku-tuur kuleyl xumo. Sida habka kuleylka kuleylka ee qaybaha kuleylka badan, ma badna in kuleyl laga filayo kuleylka PCB laftiisa si uu u qabto kuleylka, laakiin si uu ugu faafiyo kuleylka qeybta hawada ku xeeran.
Si kastaba ha noqotee, sida alaabada elektiroonigga ah ay soo galeen xilligii muhimadda milatarization ee qaybaha, cufnaanta sare, iyo golaha kuleylka badan, kuma filna in laga dhigo dusha sare ee dusha sare ee dusha sare si ay u dilaan kuleylka.
Isla mar ahaantaana, adeegsiga ballaaran ee ka kooban qaybaha dusha sare ee dusha sare sida QFP iyo BGA, kuleylka ay ka dhashaan qaybaha ayaa loo gudbiyaa golaha PCB ee lacag badan. Sidaa darteed, sida ugu wanaagsan ee lagu xalliyo kuleylka kuleylka waa in la wanaajiyo awoodda kuleylka kuleylka ee PCB laftiisa oo xiriir toos ah la leh
▼ Kuleyl viaating element. Loo qabtay ama u iftiimiyey.
▼ Kuleylka kuleylka
Soo-gaadhista naxaasta ee dhabarka dambe ee IC waxay yareynaysaa iska caabinta kuleylka ee u dhexeeya naxaasta iyo hawada
Qaabka PCB
Qalabka kuleylka xasaasiga ah ayaa lagu ridayaa aagga dabaysha qabow.
Qalabka ogaanshaha heerkulka waxaa lagu meeleeyaa booska ugu kulul.
Qalabka la midka ah ee guddiga la daabacay waa in loo habeeyaa sida ugu macquulsan ee suuragalka ah iyadoo loo eegayo qiimahooda xeebta iyo heerka kuleylka. Qalabka leh qiime-ka hooseeya ama iska caabin kuleyl oo liita Qulqulka kore (albaabka laga soo galo), aaladaha leh kuleylka weyn ama iska caabbinta kuleylka (sida kala-goysyada korantada, wareeg-guud oo isku dhafan oo isku dhafan, iwm.)
Jihada toosan, aaladaha korantada sare waxaa loo dhigayaa sidii ugu dhow geeska guddiga daabacan intii suurtogal ah si loo gaabiyo dariiqa kuleylka; Jihada toosan, aaladaha korantada sare waxaa loo dhigayaa ugu dhow dusha sare ee guddiga daabacan intii suurtogal ah si loo yareeyo saameynta aaladahaan ee heerkulka kale.
Kuleylka kuleylka ee guddiga daabacan ee qalabka ayaa inta badan ku tiirsan qulqulka hawada, sidaa darteed dariiqa socodka hawada waa in la bartaa inta lagu gudajiro qaabeynta, aaladda ama guddiga wareejinta ee daabacan waa in si macquul ah loo habeeyaa.
Marka ay qulqulayaan hawadu, waxay had iyo jeer u socotaa inay ku qulqulato meelaha caabbinta hooseeya, marka marka lagu habeeyo aaladda guddiga wareejinta ee daabacan, ka fogow inaad ka baxdo hawo-mareenka aagagga gaarka ah. Qaabeynta goleyaal wareegyo badan oo daabacan oo ku jira mashiinka oo dhan waa inay sidoo kale fiiro gaar ah u yeeshaan isla dhibaatadaas.
Qalabka heerkulka dareenka ah waxaa sida ugu fiican lagu meeleeyaa aagga heerkulka ugu hooseeya (sida salka hoose ee aaladda). Weligaa ha u dhigin qalabka kuleylka. Waxaa ugu wanaagsan in lagu khafiifiyo aalado badan oo ku saabsan diyaaradda safka hore.
Qalabka leh isticmaalka korantada ugu sareeya iyo jiil kuleylka ayaa loo habeeyey meel u dhow meesha ugu wanaagsan ee kuleylka kuleylka. Ha dul dhigin aaladaha kuleylka sareeya geeska iyo geesaha wareega ee guddiga daabacan, haddii aan kululayn biyo kuleyl ah mooyee.
Markaad qorsheynaysid u adkeysiga awoodda, dooro aalad weyn intii ugu badan ee suuragalka ah, oo ay ka dhigto meel ku filan oo kululaynta kuleylka markii la hagaajinayo qaabka loo daabacay guddiga daabacan.
