Ake sibheke design ye-PCB Board ne-PCBA
Ngikholwa ukuthi abantu abaningi bakhona-jwayelekileNge-PCB Board Design futhi kungenzeka ukuthi uyizwe empilweni yansuku zonke, kepha kungenzeka angazi okuningi nge-PCBA futhi adideke namabhodi wesifunda aphrintiwe. Manje yini ukwakheka kwebhodi le-PCB? I-PCBA ivele kanjani? Kwehluke kanjani ku-PCBA? Ake sibheke eduze.
* Mayelana ne-PCB Board Design *

Ngoba yenziwa ngokuphrinta nge-elekthronikhi, ibizwa ngeBhodi Yesekethe "ephrintiwe". I-PCB Board iyingxenye ebalulekile ye-elekthronikhi embonini ye-elekthronikhi, ukusekelwa kwezinto ze-elekthronikhi, kanye nesiphathi sokuxhumeka kukagesi kwezinto ze-elekthronikhi. Amabhodi e-PCB asetshenziswe kabanzi ekukhiqizweni nasekukhiqizweni kwemikhiqizo ye-elekthronikhi. Izici zalo ezihlukile zingafingqiwe kanjena:

1

2. Ngenxa yokuphindaphindwa nokuvumelana kwehluzo, amaphutha e-wiring nomhlangano ancishisiwe, futhi isikhathi sokulungisa imishini, ukulungisa iphutha nokuhlola kugcinwa.

I-3. Kuyasiza ekukhiqizeni okwenziwe ngomshini nokuzenzakalelayo, ukuthuthukisa ukukhiqiza kwabasebenzi, futhi kunciphise izindleko zemishini ye-elekthronikhi.

I-4. Idizayini ingalinganiswa ukuze kube lula ukuhlangana.

I-PCBA yisifinyezo seBrintiwe Board Board + Ephrintiwe, okusho ukuthi, i-PCBA iyinqubo yonke yokunamathisela ingxenye engenhla yebhodi elingenalutho lebhodi eligcwele eligcwele kanye nokucwilisa.

Qaphela: I-Surface Mount and Die Mount yizindlela zombili zokuhlanganisa amadivaysi ebhodini lesekethe eliphrintiwe. Umehluko omkhulu ukuthi ubuchwepheshe be-Surface Mount abudingi izimbobo zokumba ebhodini lesekethe ephrintiwe, izikhonkwane zengxenye zidinga ukufakwa kwizimbobo zokumba.

Ubuchwepheshe be-Surface Mount Technology (SMT) ubuchwepheshe baseMount Candle) buka ngokuyinhloko i-Pick and Beka umshini ukukhweza ezinye izingxenye ezincane ebhodini lesekethe eliphrintiwe. Inqubo yayo yokukhiqiza ifaka ukuma kwe-PCB, ukunamathisela okuthengiswayo, ukufakwa komshini wokubekwa, ukuveza ukuhlola kuhhavini kanye nokukhiqiza.

Ama-dips athi "ama-plug-in", okusho okufaka izingxenye ebhodini lesekethe eliphrintiwe. Lezi zingxenye zikhulu ngosayizi futhi azilungele ubuchwepheshe bokufaka futhi zihlanganiswe ngendlela yama-plug-ins. Izinqubo zokukhiqiza eziphambili yilezi: Adhesive, plug-in, ukuhlola, ukulungiswa kwamagagasi, ukuxubha ukuxubha nokuhlolwa kokukhiqiza.

* Umehluko phakathi kwama-PCB nama-PCBAS *

Ukusuka kwesingeniso esingenhla, singazi ukuthi i-PCBA ngokuvamile ibhekisela kwinqubo yokucubungula, futhi ingaqondwa njengebhodi lokujikeleza eliqediwe. I-PCBA ingabalwa kuphela ngemuva kokuthi zonke izinqubo ebhodini lesekethe eliphrintiwe seziqediwe. Ibhodi yesekethe ephrintiwe iyibhodi yesifunda ephrintiwe engenalutho ngaphandle kwezingxenye kulo.
