Liya kude kube nini ixesha lonikezelo emva kokuba abathengi odola iibhodi PCBA?

Ixesha lokuhanjiswa kwe-PCBA linxulumene ngokusondeleyo kwi-pre-operations.Abaxumi kufuneka babonelele ngezi zinto zilandelayo kuqala.Impahla inokuhanjiswa phakathi kweentsuku ezi-3 emva kokuba zonke izixhobo zigqityiwe.Ukuba kukho inkqubo ye-DIP, kuya kuthatha iintsuku ezi-5-7 ukuhambisa.Ukuba sineodolo engxamisekileyo enokwaziswa kwangethuba yaye sinokwenziwa amanye amalungiselelo.

Ulwazi oluza kulungiselelwa ukusetyenzwa kwePCBA:

1. Ukuveliswa okusemgangathweni kwe-BOM

2. Iifayile zePCB;

3. Ngefayile;

4. Iifayile zeJigsaw Gerber;

5. Ifayile yokulungelelanisa indawo;

6. Uluhlu lokuxuba lwe-SMT yangaphambili nasemva, imathiriyeli ye-DIP kunye noluhlu.

PCBA ukucutshungulwa kwamanyathelo:

1. I-SMT R / C kunye nezinye iindawo azikwazi ukusebenzisa izixhobo ze-granular bulk okanye ukusika izixhobo ezininzi.

2. Iindawo eziphambili ezifana ne-IC azinakususwa kwi-PCB okanye kwi-PCB esetyenziswayo.

Kutheni ukhetha PCBFuture?

1. Isiqinisekiso samandla

I-workshop ye-SMT: sinemishini yokubeka ngaphandle kunye nezixhobo ezininzi zokuhlola optical, ezinokuvelisa amanqaku ezigidi ezi-4 ngosuku.Inkqubo nganye ixhotyiswe ngabasebenzi be-QC ukuze kugcinwe umgangatho wemveliso.

Umgca wemveliso we-DIP: Kukho oomatshini ababini bokuthengisa amaza.Phakathi kwabo, kukho abasebenzi abadala abangaphezu kwama-20 abasebenze iminyaka engaphezu kwemithathu.Abasebenzi banezakhono eziphezulu kwaye badibanisa izixhobo ezahlukeneyo zeplagi ngobuchule.

2. Ukuqinisekiswa komgangatho, ukusebenza kweendleko eziphezulu

Izixhobo ezikumgangatho ophezulu zinokuncamathisela iindawo ezimile kakuhle, BGA, QFN, 0201 imathiriyeli.Isenokusetyenziswa njengemodeli yokuxhoma kunye nokubeka izinto ezininzi ngesandla.

Zombini iisampuli kunye neebhetshi ezinkulu nezincinci zinokuveliswa.Ubungqina buqala kwi-800 yuan, kwaye iibhetshi ziqala kwi-0.008 yuan/point.Akukho mali yokuqalisa.

3. Amava atyebileyo kwi-SMT kunye ne-soldering yeemveliso ze-elektroniki, ukuhanjiswa okuzinzile

Iinkonzo eziqokelelweyo kumawaka eenkampani ze-elektroniki, ezibandakanya iinkonzo zokusetyenzwa kwetshiphu ye-SMT kwiintlobo ngeentlobo zezixhobo zeemoto kunye neebhodi zolawulo lwemizi-mveliso.Iimveliso zithunyelwa eYurophu nase-United States Rhoqo, kwaye umgangatho unokuqinisekiswa ngabathengi abatsha nabadala.

Ukuhanjiswa ngexesha, iintsuku ezi-3-5 emva kokuba izinto zigqitywe ngokuqhelekileyo, kwaye iibhetshi ezincinci nazo zingathunyelwa ngosuku olufanayo.

4. Isakhono esinamandla sokugcinwa kunye nenkonzo egqibeleleyo emva kokuthengisa

Injineli yokugcina inamava atyebileyo anokulungisa iimveliso ezineziphene ezibangelwa yi-patch welding eyahlukeneyo, kwaye sinokuqinisekisa izinga lokunxibelelana kwibhodi yesekethe nganye.

Inkonzo yabathengi iya kuphendula nanini na kwiiyure ze-24 kwaye isombulule iodolo yakho ngokukhawuleza.
