PCBA tana nufin tsarin hawa, sakawa da kuma siyar da kayan PCB marasa tushe.Tsarin samarwa na PCBA yana buƙatar shiga cikin jerin matakai don kammala samarwa.Yanzu, PCBFuture zai gabatar da matakai daban-daban na samar da PCBA.
Ana iya raba tsarin samar da PCBA zuwa manyan matakai da yawa, SMT faci sarrafa → DIP plug-in sarrafa → PCBA gwaji → gama samfurin taro.
Na farko, hanyar haɗin sarrafa facin SMT
Tsarin sarrafa guntu na SMT shine: haɗaɗɗen solder manna → buguwar solder manna → SPI → hawawa → reflow soldering → AOI → sake aiki
1, hadawa solder manna
Bayan an fitar da manna daga cikin firij a narke, ana motsa shi da hannu ko na'ura don dacewa da bugu da siyarwa.
2, bugu mai solder
Sanya manna solder a kan stencil, kuma yi amfani da squeegee don buga manna mai siyar a kan faifan PCB.
3, SPI
SPI ita ce mai gano kauri na solder, wanda zai iya gano bugu na manna solder da sarrafa tasirin bugu na manna solder.
4. Hawaye
Ana sanya abubuwan SMD akan mai ciyarwa, kuma shugaban injin sanyawa daidai yana sanya abubuwan da aka gyara akan mai ciyarwa akan pads na PCB ta hanyar ganewa.
5. Reflow soldering
Wuce allon PCB ɗin da aka ɗora ta hanyar sayar da reflow, kuma manna mai-kamar solder ana dumama shi zuwa ruwa ta yanayin zafi mai yawa a ciki, kuma a ƙarshe an sanyaya kuma a ƙarfafa don kammala siyarwar.
6.AOI
AOI shine dubawar gani ta atomatik, wanda zai iya gano tasirin walda na hukumar PCB ta hanyar dubawa, da kuma gano lahani na hukumar.
7. gyara
Gyara lahanin da AOI ko binciken hannu suka gano.
Na biyu, hanyar haɗin toshewar DIP
Tsarin sarrafa toshewar DIP shine: toshe-in → sayar da igiyar ruwa → yanke ƙafa
1, toshe
Sarrafa fil ɗin kayan toshewa kuma saka su akan allon PCB
2, sayar da igiyar ruwa
An sanya allon da aka saka don siyar da igiyar ruwa.A cikin wannan tsari, za a fesa tin mai ruwa a kan allon PCB, sannan a sanyaya a ƙarshe don kammala sayar da kayan.
3, yanke ƙafafu
Fin ɗin allon da aka siyar sun yi tsayi da yawa kuma suna buƙatar gyarawa.
4, sarrafa walda
Yi amfani da ƙarfe mai siyar da wutar lantarki don siyar da kayan aikin da hannu.
5. Wanke farantin
Bayan sayar da igiyar igiyar ruwa, allon zai zama datti, don haka kuna buƙatar amfani da ruwan wanka da tankin wanka don tsaftace shi, ko amfani da na'ura don tsaftacewa.
6, ingancin dubawa
Bincika kwamitin PCB, samfuran da ba su cancanta ba suna buƙatar gyara, kuma samfuran ƙwararrun kawai za su iya shiga tsari na gaba.
Na uku, gwajin PCBA
Ana iya raba gwajin PCBA zuwa gwajin ICT, gwajin FCT, gwajin tsufa, gwajin girgiza, da sauransu.
Gwajin PCBA shine babban gwajin.Dangane da samfuran daban-daban da buƙatun abokin ciniki daban-daban, hanyoyin gwajin da aka yi amfani da su sun bambanta.
Na hudu, gamawar taron samfur
An haɗa allon PCBA da aka gwada don harsashi, sannan a gwada, kuma a ƙarshe ana iya jigilar shi.
Samar da PCBA shine hanyar haɗi ɗaya bayan ɗaya.Duk wata matsala a cikin kowace hanyar haɗin yanar gizon za ta sami tasiri mai yawa akan ingancin gabaɗaya, kuma ana buƙatar tsananin kulawa da kowane tsari.
