Adigoo isticmaalaya saamaynta culayska ee kirishbooyada birta, gage-ga culeyska ku xiran PCBA waxa lagu qiyaasi karaa isbeddesha qiimihiisu iska caabbinta marka PCBA qalloocdo oo ay noqoto qaab farsamaysan.Cadaadiska la qiyaasey ayaa la barbar dhigi karaa culeyska ugu dambeeya si loo go'aamiyo khatarta PCBA-da qallafsanaan ee qaybaha ama dillaaca dhibcaha qaybaha.Bixi jihada tallaabooyinka hagaajinta habka PCBA.
Nidaamka tijaabada cadaadiska ayaa ogaanaya isbeddelka korantada ee uu keeno isbeddelka caabbinta culeyska culeyska iyada oo loo marayo buundada Wheatstone, ka dibna u beddela isbeddelka korantada ee cadaadiska iyada oo loo marayo barnaamijka ku jira software-ka tijaabada cadaadiska.
Ubaxa cidhiidhiga ahi waa cabirka cidhiidhiga ah ee ka kooban saddex xargo oo xasaasi ah oo madax-banaan, kuwaas oo midba midka kale ku urursan yahay meel ay wadaagaan si loo cabbiro cidhiidhiga dhinaca faasaskooda ee meel wadaag ah.
Cadaadiska waxaa lagu qeexaa sida (isbedel dhererka)/(dhererka asalka ah), waa tiro jireed oo aan cabbir lahayn, marka lagu jiro baaritaanka culeyska PCBA, sababtoo ah qiimaha culeysku aad ayuu u yar yahay, badanaa waxaa lagu sifeeyaa microstrain (με), marka loo eego 106* (isbedel dhererka) /(dhererka asalka ah) si loo qeexo microstrain.
Tijaabada culayska PCBA-da, xaalada culayska PCBA waa xaalada culayska diyaarada.Nidaamka falanqaynta tijaabada culaysku waxa uu xisaabin karaa culayska iyo culayska ugu weyn ee habka PCBA-da iyadoo la cabbirayo wakhtiga dhabta ah ee qiimaha culayska saddexda jiho ee ubaxa, si loo xukumo in culayska badeecada habsocodka uu ka sarreeyo heerka.
Tallaabooyinka ka baxsan xadka culeyska ayaa loo arkaa inay xad dhaaf yihiin waxaana loo aqoonsaday tallaabo sax ah.Xadka cadaadiska waxaa laga heli karaa macmiilka, alaab-qeybiyaha, ama dhaqamada caanka ah ee ka dhex jira ganacsiga/warshada (oo laga soo qaatay IPC_JEDEC-9704A).
Halka cidhiidhiga udub-dhexaadka ahi uu yahay ta ugu weyn uguna yar cadaadiska orthogonal ee diyaaradda, oo isku toosan oo taangiga jihada uu yahay eber.Imtixaanka culeyska PCBA-da, culeyska ugu muhiimsan waxaa badanaa lagu xisaabiyaa iyadoo lagu cabbirayo cabbirka mitirka muhiimka ah.Heerka culeysku wuxuu muujinayaa heerka isbeddelka cadaadiska halkii halbeeg, kaas oo loo isticmaalo in lagu cabbiro khatarta waxyeellada qaybaha.
