Ndikukhulupirira kuti anthu ambiri sadziwa mawu okhudzana ndi mafakitale amagetsi monga PCB circuit board ndi SMT chip processing. Izi nthawi zambiri zimamveka m’moyo watsiku ndi tsiku, koma anthu ambiri sadziwa zambiri za PCBA ndipo nthawi zambiri amasokonezeka ndi PCB. Ndiye PCBA ndi chiyani? Kodi pali kusiyana kotani pakati pa PCBA ndi PCB? Tiyeni tidziwe.

I- PCBA:
PCBA ndondomeko: PCBA = kusindikizidwa gulu gulu msonkhano, ndiye chopanda PCB bolodi akudutsa njira yonse ya SMT Mumakonda ndi kuviika pulagi-mu, amene amatchedwa ndondomeko PCBA mwachidule.

II-PCB:
Printed circuit board (PCB) ndi gawo lofunikira lamagetsi, chithandizo chazigawo zamagetsi ndi chonyamulira cha kugwirizana kwamagetsi pazigawo zamagetsi. Chifukwa chakuti amapangidwa ndi makina osindikizira, amatchedwa bolodi “losindikizidwa”.

Gulu Lozungulira Losindikizidwa:
Chidule cha Chingerezi cha PCB ( bolodi losindikizidwa) kapena PWB ( bolodi losindikizidwa) nthawi zambiri amagwiritsidwa ntchito. Ndi gawo lofunikira lamagetsi, kuthandizira pazigawo zamagetsi ndi wopereka kugwirizana kwa dera la zipangizo zamagetsi. Gulu loyang’anira dera lachikhalidwe limatengera njira yosindikizira kuti ipangitse kuzungulira ndi kujambula, motero imatchedwa bolodi losindikizidwa kapena bolodi losindikizidwa. Chifukwa cha miniaturization mosalekeza ndi kuyengedwa kwa zinthu zamagetsi, pakali pano, matabwa ambiri ozungulira amapangidwa ndikumangirira etching kukana (kukanikiza filimu kapena zokutira) ndi etching pambuyo kuwonekera ndi chitukuko.
Chakumapeto kwa zaka za m’ma 1990, pamene mapulani ambiri osindikizira osindikizira amitundu yambiri adayikidwa patsogolo, bolodi yosindikizira yamitundu yambiri yakhala ikugwiritsidwa ntchito mpaka pano.

Kusiyana pakati pa PCBA ndi PCB:
1. PCB ilibe zigawo
2. PCBA imatanthawuza kuti wopanga atapeza PCB ngati zopangira, zida zamagetsi zomwe zimafunikira kuwotcherera ndi kusonkhana pa bolodi la PCB kudzera pa SMT kapena plug-in processing, monga IC, resistor, capacitor, crystal oscillator, transformer ndi zina. zida zamagetsi. Pambuyo pa kutentha kwambiri kutentha mu ng’anjo ya reflow, kugwirizana kwa makina pakati pa zigawo ndi bolodi la PCB kupangidwa, kuti apange PCBA.
Kuchokera pamwambapa, titha kudziwa kuti PCBA nthawi zambiri imatanthawuza njira yopangira, yomwe imatha kumvekanso ngati bolodi yomalizidwa yozungulira, ndiye kuti, PCBA ikhoza kuwerengedwa pokhapokha njira za PCB zikamalizidwa. PCB imanena za chopanda kanthu bolodi losindikizidwa wopanda mbali zake.
