Kodi pali kusiyana kotani pakati pa PCB ndi PCBA?

Ndikukhulupirira kuti anthu ambiri sadziwa PCB matabwa dera, ndipo mwina anamva nthawi zambiri m'moyo watsiku ndi tsiku, koma iwo sangadziwe zambiri za PCBA, ndipo mwina ngakhale kusokonezedwa ndi PCB.Ndiye PCB ndi chiyani?Kodi PCBA inasintha bwanji?Kodi pali kusiyana kotani pakati pa PCB ndi PCBA?Tiyeni tione bwinobwino.

Za PCB

PCB ndiye chidule cha Printed Circuit Board, chomasuliridwa ku China chimatchedwa bolodi losindikizidwa, chifukwa amapangidwa ndi makina osindikizira amagetsi, amatchedwa " bolodi losindikizidwa ".PCB ndi gawo lofunika lamagetsi pamakampani opanga zamagetsi, chothandizira pazigawo zamagetsi, komanso chonyamulira cholumikizira zamagetsi zamagetsi zamagetsi.PCB yakhala ikugwiritsidwa ntchito kwambiri popanga zinthu zamagetsi.Makhalidwe apadera a PCB akufotokozedwa mwachidule motere:

1. Kuchuluka kwa mawaya, kukula kochepa ndi kulemera kochepa, zomwe zimathandiza kuti miniaturization ya zipangizo zamagetsi.

2. Chifukwa cha kubwereza ndi kusasinthasintha kwa zithunzi, zolakwika mu wiring ndi msonkhano zimachepetsedwa, ndipo kukonza zipangizo, kusokoneza ndi nthawi yoyendera zimasungidwa.

3. Zimathandiza kupanga makina ndi kupanga zokha, zomwe zimapangitsa kuti ntchito zitheke komanso kuchepetsa mtengo wa zipangizo zamagetsi.

4. Mapangidwewo akhoza kukhazikitsidwa kuti athandizire kusinthasintha.

ZaPCBA

PCBA ndiye chidule cha Printed Circuit Board + Assembly, kutanthauza kuti PCBA imadutsa munjira yonse yopanga PCB blank board SMT ndiyeno DIP plug-in.

Chidziwitso: SMT ndi DIP ndi njira zophatikizira magawo pa PCB.Kusiyana kwakukulu ndikuti SMT sifunikira kubowola mabowo pa PCB.Mu DIP, zikhomo za PIN za zigawozo ziyenera kuikidwa m'mabowo obowola.

Ukadaulo wapamtunda wa SMT (Surface Mounted Technology) umagwiritsa ntchito zokwera kwambiri kuyika tizigawo tating'ono ta PCB.Njira yopangira ndi: PCB board positioning, solder paste printing, mounter mounter, ndi reflow Furnace ndi kuyendera komaliza.

DIP amatanthauza "plug-in", ndiko kuti, kuyika magawo pa bolodi la PCB.Uku ndiko kuphatikizika kwa magawo mu mawonekedwe a plug-ins pomwe mbali zina ndi zazikulu ndipo sizoyenera kuyika ukadaulo.Njira yayikulu yopangira ndi: zomatira zomatira, pulagi-mu, kuyendera, kutenthetsa mafunde, kusindikiza ndikumaliza kuyendera.

* Kusiyana pakati pa PCB ndi PCBA *

Kuchokera pamwamba pamwamba, tingathe kudziwa kuti PCBA zambiri amatanthauza ndondomeko processing, amenenso tingamvetse ngati bolodi yomalizidwa dera, kutanthauza kuti PCBA akhoza kuwerengedwa pambuyo ndondomeko pa bolodi PCB anamaliza.PCB imatanthawuza bolodi losindikizidwa lopanda kanthu popanda zigawo zake.

Nthawi zambiri: PCBA ndi bolodi yomalizidwa;PCB ndi gulu lopanda kanthu.
