Waa maxay PCB iyo PCBA?

Sabuurada wareegga daabacan (Printed circuit board, loo yaqaan PCB) waa substrate lagu ururiyo qaybaha elegtarooniga ah, waana loox daabacan oo ka samaysan isku xirka bar-ilaa-dhibcood iyo qaybo daabacan oo ka samaysan substrate guud iyadoo la raacayo naqshad la sii go'aamiyay.Shaqada ugu weyn ee PCB waa in la sameeyo noocyo kala duwan oo qalab elektaroonik ah samaynta isku xirka wareegga ee horay loo sii go'aamiyay, doorka gudbinta gudbinta, waa isku xirka muhiimka ah ee elektiroonigga ah ee alaabta elektiroonigga ah.

Tayada wax soo saarka ee looxyada daabacan ma aha oo kaliya inay si toos ah u saameeyaan isku halaynta alaabta elektaroonigga ah, laakiin sidoo kale waxay saamaysaa tartanka guud ee alaabta nidaamka, sidaas darteed PCB waxaa loo yaqaan "hooyada alaabta elektaroonigga ah".
Waqtigan xaadirka ah, noocyada kala duwan ee alaabada elektiroonigga ah sida kombuyuutarrada gaarka ah, telefoonnada gacanta, kamaradaha dijitalka ah, qalabka elektaroonigga ah, qalabka dayax-gacmeedka dayax-gacmeedka, qaybaha baabuurta iyo wareegyada kale, dhammaan waxay isticmaalaan PCB, kuwaas oo laga arki karo meel kasta oo nolol maalmeedkeena ah.

Iyada oo isbeddelka naqshadeynta ee hawlaha kala duwan, yaraynta iyo miisaanka khafiifka ah ee alaabta elektiroonigga ah, qalabyo yar yar ayaa lagu daraa PCB-ga, lakabyo badan ayaa la isticmaalaa, iyo cufnaanta isticmaalka qalabka ayaa sidoo kale kordhiya, taasoo ka dhigaysa codsiga PCB mid adag.

PCB faaruq ah oo loo maro SMT (teknooloojiyada dusha sare ee dusha sare), ama iyada oo loo marayo DIP (laba xidhmo-line) fur-in dhammaan habka, loo yaqaan PCBA (Printed Circuit Board Assembly).
