Inqubo Yomhlangano we-SMT
1. Indawo (ukwelapha)
Indima yayo ukuncibilikisa i-patch glue ukuze izingxenye zokukhweza ezingaphezulu kanye nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.
Izinto ezisetshenziswayo ihhavini elaphayo, etholakala ngemuva komshini wokubeka kulayini we-SMT.
2. Ukuphinda kufakwe i-soldering
Indima yayo ukuncibilikisa unamathisele we-solder, ukuze izingxenye ze-surface mount kanye nebhodi le-PCB kuhlanganiswe ngokuqinile ndawonye.Izinto ezisetshenziswayo kwakuyi-oven reflow, etholakala ngemuva kwamaphedi.
I-Mounter kulayini wokukhiqiza we-SMT.
3. Ukuhlanza umhlangano we-SMT
Ekwenzayo ukususa izinsalela ze-solder ezifana no-ux
I-PCB ehlanganisiwe iyingozi emzimbeni womuntu.Impahla esetshenziswa umshini wokuwasha, indawo kungaba
Ayilungisiwe, ingase ibe ku-inthanethi noma ingaxhunyiwe ku-inthanethi.
4. Ukuhlolwa komhlangano we-SMT
Umsebenzi wayo ukuhlola izinga lokushisela kanye nekhwalithi yokuhlanganisa
Ibhodi le-PCB elihlanganisiwe.
Izinto ezisetshenziswayo zihlanganisa ingilazi yokukhulisa, isibonakhulu, isihloli esingaphakathi kwesifunda (ICT), isihloli senaliti, ukuhlola okuzenzakalelayo (AOI), uhlelo lokuhlola lwe-X-RAY, umhloli osebenzayo, njll.
5. Ukuhlelwa kabusha komhlangano we-SMT
Iqhaza layo wukulungisa kabusha ibhodi le-PCB elihlulekile
Iphutha.Amathuluzi asetshenziswayo yi-soldering iron, i-rework station, njll.
noma yikuphi kulayini wokukhiqiza.Njengoba wazi, kunezinkinga ezincane ngesikhathi sokukhiqiza, ngakho-ke ukuhlangana kabusha kwezandla kuyindlela engcono kakhulu.
6. Ukupakishwa komhlangano we-SMT
I-PCBMay ihlinzeka ngokuhlanganisa, ukupakishwa ngokwezifiso, ukulebula, ukukhiqizwa kwegumbi elihlanzekile, ukuphathwa kokuvala inzalo nezinye izixazululo ukuze kunikeze isisombululo esiphelele sangokwezifiso sezidingo zenkampani yakho.
Ngokusebenzisa okuzenzakalelayo ukuze sihlanganise, sihlanganise futhi siqinisekise imikhiqizo yethu, singanikeza amakhasimende ethu inqubo yokukhiqiza enokwethenjelwa nesebenza ngempumelelo.
Umhlinzeki wesevisi yokukhiqiza ngogesi Wezimoto, sifaka izicelo eziningi:
> Umkhiqizo wekhamera yezimoto
> Izinzwa zokushisa nomswakama
> Isibani esikhulu
> Ukukhanyisa okuhlakaniphile
> Amamojula wamandla
> Izilawuli zeminyango nezibambo zeminyango
> Amamojula okulawula umzimba
> Ukuphathwa kwamandla
Okwesithathu, amanani ahlukile ngenxa yobunkimbinkimbi nokuminyana.
I-PCB izoba yizindleko ezihlukile ngisho noma izinto zokwakha nenqubo kuyafana, kodwa ngobunkimbinkimbi obuhlukene kanye nokuminyana.Isibonelo, uma kunezimbobo eziyi-1000 kuwo womabili amabhodi esekethe, ububanzi bembobo yebhodi elilodwa bukhulu kuno-0.6mm futhi ububanzi bembobo kwelinye ibhodi bungaphansi kuka-0.6mm, okuzokwenza izindleko zokumba ezihlukene.Uma amabhodi esifunda amabili afana kwezinye izicelo, kodwa ububanzi bomugqa buhlukile bubuye bubangele izindleko ezihlukene, njengokuthi ububanzi bebhodi elilodwa bukhulu kuno-0.2mm, kanti elinye elinalo lingaphansi kuka-0.2mm.Ngoba ububanzi bamabhodi bungaphansi kuka-0.2mm anezinga eliphezulu elinesici, okusho ukuthi izindleko zokukhiqiza zingaphezu kokuvamile.
Okwesine, amanani ahlukile ngenxa yezidingo ezihlukahlukene zamakhasimende.
Izidingo zekhasimende zizothinta ngqo izinga elingenasici ekukhiqizeni.Njengezivumelwano zebhodi elilodwa le-IPC-A-600E class1 zidinga izinga lokuphasa elingu-98%, kuyilapho izivumelwano zesigaba3 zidinga kuphela izinga lokuphasa elingu-90%, okubangela izindleko ezihlukene zefekthri futhi ekugcineni kuholele ezinguqukweni zentengo yomkhiqizo.
