Inqubo yokukhiqiza i-PCBA ingahlukaniswa ngezinqubo eziningi ezinkulu:
I-PCB Design and Development → Ukucutshungulwa kwe-SMT Patch → Dip Plug-in Ukucubungula → Ukuhlolwa kwe-PCBA → Ukulwa nomkhiqizo okuqediwe.
Okokuqala, ukwakhiwa kwe-PCB nentuthuko
Isidingo se-1.Product
Isikimu esithile singathola inani elithile lenzuzo emakethe yamanje, noma abathanda kakhulu bafuna ukuqeda ukwakheka kwabo kwe-DIY, khona-ke kuzokhiqizwa isidingo somkhiqizo esihambisanayo;
2. Design and Development
Kuhlanganiswe nezidingo zomkhiqizo wekhasimende, onjiniyela be-R & D bazokhetha i-Chip ehambisanayo kanye nenhlanganisela yesekethe yangaphandle yesisombululo se-PCB ukufeza izidingo zomkhiqizo, le nqubo yisikhathi eside, okuqukethwe okubandakanyeka lapha kuzochazwa ngokwahlukile;
3, ukukhiqizwa kwesivivinyo sesampula
Ngemuva kokuthuthukiswa kanye nokwakhiwa kwe-PCB yokuqala, umthengi uzothenga izinto ezihambisanayo ngokusho kwe-BOM enikezwe ukukhiqizwa (10pcs), ukukhiqizwa kwesivivinyo se-batch (i-50pcs ~ 100pcs), bese kuthi ukukhiqizwa kwecala lokuhlola) Isigaba Sokukhiqiza Masisindo.
Okwesibili, ukucubungula kwe-SMT Patch
Ukulandelana kokusebenza kwe-SMT Patch kuhlukaniswe: Ukuvuka okubonakalayo → Ukungena kwa-Solde → I-SPI →
1. Izinto zokubhaka
Ama-chips, amabhodi we-PCB, amamojula kanye nezinto ezikhethekile ezibe sesitokisini isikhathi esingaphezu kwezinyanga ezintathu, kufanele zibhakwe ku-120 ℃ 24h. Okwe-Mic Microphones, amalambu aholwa kanye nezinye izinto ezingamelana namazinga okushisa aphezulu, kufanele abhakwe ku-60 ℃ 24h.
I-2, SOLES STEASTE AFFACE (lokushisa lokubuyisa → ukuvuselelwa → ukusetshenziswa)
Ngoba i-solde yethu i-solde igcinwa emvelweni ka-2 ~ 10 ℃ isikhathi eside, idinga ukubuyiselwa ekwelashweni kwezinga lokushisa ngaphambi kokusebenzisa, nangemva kokushisa okushisayo, bese kudingeka ukuthi kuphrintwe nge-blender, bese kudinga ukuphrinta.
3. Ukutholwa kwe-SPI3D
Ngemuva kokuthi i-solder passe iphrintiwe ebhodini lesekethe, i-PCB izofinyelela kudivayisi ye-SPI ngebhande lokuhambisa, futhi i-SPI izobona ubukhulu bokuphrinta, ububanzi, ubude bokuphrinta okuthengiswayo komthengisi.
4
Ngemuva kokuthi i-PCB igeleze emshinini we-SMT, umshini uzokhetha izinto ezifanele bese unamathisela kwinombolo ehambisanayo ngohlelo olusemthethweni;
5. Thumela i-welding
I-PCB egcwele ukugeleza okubonakalayo ngaphambili kwe-walding, futhi idlula ezindaweni zokushisa eziyishumi kusuka ku-148 ℃ kuya ku-252 ℃ kuya ku-252
6, Online Aoi Test
I-AOI ingumtshina we-optical othomathikhi, ongabheka i-PCB Board ngaphandle kwesithando ngokuthwebula okunencazelo, futhi angabheka ukuthi ngabe kukhona okuhlangene ku-PCB Board, noma ngabe okuhlangene kushintshiwe phakathi kwezakhi nokuthi ngabe ithebhulethi ixhunyiwe yini.
7. Ukulungiswa
Ngezinkinga ezitholakala ebhodini le-PCB e-AOI noma ngesandla, lidinga ukulungiswa ngunjiniyela wesondlo, futhi ibhodi le-PCB elilungisiwe lizothunyelwa kwi-plug ye-DIP kanye nebhodi elijwayelekile elingaxhunyiwe ku-inthanethi.
Okwesithathu, i-Plug-in
Inqubo yokufaka i-plug-in ihlukaniswe: ukwakheka → plug-in → i-wave fordering → Ukusika unyawo → Ukubamba ipuleti → Ukuhlola ipuleti
1. Ukuhlinzwa kwepulasitiki
Izinto zokwenziwa kwezinto ezisetshenzisiwe zonke izinto zokwakha ezijwayelekile, kanye nobude bezinto esikudingayo buhlukile, ngakho-ke kudingeka babumbe izinyawo zezinto zokwakha ngaphambi kwesikhathi, ukuze ubude nokwakheka kwezinyawo kulungele ukufeza i-plug-in noma ukuthumela insimbi.
2. Plug-in
Izakhi eziqediwe zizofakwa ngokuya ngethempulethi ehambisanayo;
3, amagagasi we-soldering
Ipuleti elifakiwe libekwe ku-jig ngaphambili kwe-wave soldering. Okokuqala, i-flux izofafazwa ezansi ukusiza ukushisa. Lapho ipuleti lifika esiqongweni sesithando se-tin, amanzi e-tin esithandweni somlilo azontanta futhi axhumane ne-PIN.
4. Sika izinyawo
Ngoba izinto zokusebenza zangaphambi kokusebenza zizoba nezidingo ezithile zokubeka eceleni iPIN ende, noma izinto ezingenayo azilungele ukucubungula, i-PIN izolungiswa ekuphakameni okufanele ngencwadi;
5. Ubambe uthini
Kungenzeka kube nezinto ezimbi ezinjengezimbobo, ama-mainholes, uphuthelwe ukuthutha, ukufudumala okungamanga nokunye okunjalo ezihlotsheni zeBondb yethu yePCB ngemuva kothando. Umnikazi wethu we-tin uzowalungisa ngokulungiswa kwezandla.
6. Geza ibhodi
Ngemuva kwe-wave soldering, ukulungisa nezinye izixhumanisi ezingaphambili, kuzoba khona ezinye izinhlansi ezisalayo noma ezinye izimpahla ezebiwe ezinamathiselwe endaweni yePIN yeBhodi yePCB, edinga ukuthi abasebenzi bethu bahlanze indawo yaso;
7. Ukuhlolwa kwekhwalithi
I-PCB Board Complents Iphutha kanye nesheke lokuvuza, ibhodi le-PCB elingaqinisekisiwe lidinga ukulungiswa, kuze kube yilapho kufanelekile ukuqhubeka nesinyathelo esilandelayo;
4. Ukuhlolwa kwe-PCBA
Ukuhlolwa kwe-PCBA kungahlukaniswa ku-ICT Test, FCT Test, Ukuhlolwa kokuguga, ukuhlolwa kokudlidliza, njll
Ukuhlolwa kwe-PCBA kungukuhlolwa okukhulu, ngokuya ngemikhiqizo ehlukene, izidingo zamakhasimende ezahlukene, izindlela zokuhlola zihlukile. Ukuhlolwa kwe-ICT ukuthola isimo se-welding sezakhi kanye nesimo se-on-off of lines, ngenkathi ukuhlolwa kwe-FCT ukuthola amapharamitha okufaka nokukhipha we-PCBA Board ukubheka ukuthi ahlangabezana yini nezidingo.
Ezinhlanu: I-PCBA ezintathu anti-coating
I-PCBA kathathu inqubo yokulwa nenqubo yokulwa neyalena yile: Ukuxubha uhlangothi a
0.1mm-0.3mm6. Yonke imisebenzi yokuhlanganisa izokwenziwa emazingeni okushisa angenayo ngaphansi kuka-16 ℃ kanye nomswakama ohlobene ngaphansi kwama-75%. I-PCBA ezintathu anti-coati-coatis iseningi, ikakhulukazi izinga lokushisa elithile kanye nomswakama onokhahlo kathathu, umswakama, ukuthuthumela, ukuncipha, ukuthuthumela, ukunqanyulwa, ukuthuthumela, ukuhlukaniswa kwezindawo zokuqina, ukuhlukaniswa kokuguguleka kwangaphandle, ukungcola nokunye. Indlela yokufafaza yindlela esetshenziswa kakhulu esetshenziswa embonini.
Kuqedwe Umhlangano Womkhiqizo
7.IBhodi yePCBA ehlanganisiwe enohlolo oluhlangene lwegobolondo, bese kuthi wonke umshini ukuguga nokuhlola, nemikhiqizo engenazinkinga ngokuhlolwa kokuguga kungathunyelwa.
Ukukhiqizwa kwe-PCBA kuyisixhumanisi sesixhumanisi. Noma iyiphi inkinga kwinqubo yokukhiqiza i-PCBA izoba nomthelela omkhulu kwikhwalithi ephelele, futhi inqubo ngayinye idinga ukulawulwa ngokuphelele.
