Nguva dzinoshanduka, maitiro ari kuwedzera, uye ikozvino bhizinesi remamwe mabhizimusi ePCB akawedzera zvakanyanya, makambani mazhinji anopa PCB board, SMT patch, BOM uye mamwe masevhisi, ayo PCB board inosanganisirawo FPC inoshanduka bhodhi uye PCBA. PCBA i "muzivikanwi wekare", inenge yakareba sekunge ichibatanidza PCB inogona kuona mufananidzo wePCBA, nhasi tichazivisa zvikuru "muenzi anowanzogara" anowanzoonekwa.
PCBA ndiyo chidimbu cheChirungu Yakadhindwa Circuit Board +Assembly, kureva kuti, PCB isina chinhu bhodhi kuburikidza neSMT pachidimbu, kana kuburikidza neDIP plug-mukuita kwese, kunonzi PCBA. Iyi iNzira yekunyora inowanzoshandiswa kuChina, uye nzira yekunyora yakajairwa muEurope nekuUnited States iPCB 'A, pamwe ne“' “, inodaidzwa kuti dimikira repamutemo.
Pakupera kwema1990, apo akawanda ekuwedzera akadhindwa edunhu mabhodhi akakurudzirwa, ekuwedzera layer akadhindwa edunhu mabhodhi akaiswawo zviri pamutemo mukuita muhuwandu hukuru, kusvika zvino. Izvo zvakakosha kuti ugadzire yakasimba bvunzo zano remahombe, akakwira-density akadhindwa edunhu redunhu magungano (PCBA) kuve nechokwadi chekutevedzera uye kushanda nedhizaini. Pamusoro pekuvakwa nekuedzwa kwemagungano aya akaomarara, mari inoiswa muzvikamu zvemagetsi chete inogona kunge yakakwira - kusvika kumadhora zviuru makumi maviri nezvishanu kana chikwata chikazoedzwa. Nekuda kwekudhura uku, kutsvaga nekugadzirisa matambudziko egungano inhanho inotokosha kupfuura zvayaive kare.
Yakadhindwa redunhu bhodhi, inozivikanwawo seyakadhindwa redunhu bhodhi, yakadhindwa redunhu bhodhi, kazhinji shandisa Chirungu chipfupiso PCB, chinhu chakakosha chemagetsi chikamu, inotsigira muviri wemagetsi zvinoriumba, ndiye mupi wemagetsi chikamu chedunhu kubatana. Nekuti inogadzirwa uchishandisa tekinoroji yekudhinda yemagetsi, inonzi "yakadhindwa" redunhu bhodhi. Mumashoko akareruka, PCBA inogona kunge iri nhevedzano yemaitiro anoumbwa neSMT chigamba kugadzirisa, DIP plug-in kugadzirisa uye PCBA kuyedzwa, kunonzi PCBA.
Zvakajairwa hazvina kunaka sekunzwisisa kwechokwadi, pane manzwiro ekuzorodza PCBA nhasi?
