PCB ( Daabacidda Circuit Board ), sidoo kale loo yaqaan guddiga circuit ku daabacan, waa qayb muhiim ah oo elektaroonik ah, taageero ah qaybaha elektarooniga ah, iyo side for xiriir korontada qaybaha electronic. Sababta oo ah waxa la sameeyey by daabacaadda elektarooniga ah, waxa la yidhaahdaa waa "daabacaadda" guddiga circuit ah.

function

Ka dib markii qalabka electronic ansixiyeen guddiga daabacan, ay sabab u tahay joogta ah, oo loox la mid ah ku daabacan, taararka buuggan waxaa fogaaday, iyo qaybaha elektaroonik ah si toos ah gashan karaa ama dhajinta, si toos ah soldered, oo si toos ah u ogaado si loo hubiyo in tayada qalabka elektarooniga ah . Kordhi wax soo saarka shaqada, yareeyo kharashka, iyo fududeeyo dayactirka.

Horumarin

looxyada daabacay ayaa waxaad fartaan ka layers hal si double-madaxyo simanna, multi-lakabka iyo dabacsanaan, oo weli sii wado isbedelka ay ka soo jeedaan. Sababo la horumarinta joogtada ah ee sax sare, cufnaanta sare iyo isku halaynta sare, mugga waa la dhimay, kharashka waa la dhimay, iyo waxqabadka la soo hagaagtay, si ay guddiga daabacay sii haystaa koboca xoog leh horumarinta qalabka elektarooniga ah ee mustaqbalka .

Qoondaynta

Sida laga soo xigtay tirada layers, guddiga Bannaanka u qaybsan yahay saddex qaybood oo waaweyn: guddi hal, guddi double, iyo guddiga circuit multi-lakabka.

marka hore waa guddi hal. On PCB ugu aasaasiga ah, qaybo ka mid ah yihiin hal dhinac ah iyo fiilooyin badan yihiin dhinaca kale. Maxaa yeelay, silig u muuqda oo kaliya hal dhinac, waxa loo yaqaan guddiga circuit hal dhinac.

darfaha Single caadi ahaan waa fudud si ay u sameeyaan iyo hoos u dhac kharashka, laakiin faa'ido ah waa in ay laguma dabbaqi karo in waxyaabaha ku jira aad u adag.

guddi The double waa dheeraad ah oo ka mid ah guddiga hal. Marka xarkaha lakabka hal ma buuxin karaan baahida sheyga elektaroonik ah, guddiga double waxaa loo isticmaalaa.

Labada dhinac waxay leeyihiin raad copper-u guntaday, iyo vias waxaa loo isticmaali karaa si ay u soo jeedin on khadadka u dhexeeya labada lakab si ay u sameeyaan xiriir network la doonayo.

A guddiga multi-lakabka loola jeedaa guddiga daabacan isagoo wata saddex ama in ka badan layers of lakabka tabinta ah hannaanka iyo wax interposed qalabada therebetween ah, iyo qaababka tabinta therebetween waxaa isku xidhan sida loo baahan yahay.

looxyada circuit Multi-lakabka waa wax ka mid ah horumarinta macluumaad technology elektaroonik ah jihada of xawaaraha sare, multi-shaqayn, awood weyn, mugga yar, khafiifinta iyo miisaanka iftiin.

Sida laga soo xigtay sifooyinka, guddiga circuit wuxuu u qaybsan yahay guddiga jilicsan (qoyska), guddiga adag (PCB), iyo guddiga jilicsan iyo mid adag (FPCB).
