Ndikupatseni PCBA chidziwitso chatsopano!Bwerani mudzawone!
PCBA ndi njira yopangira bolodi yopanda kanthu ya PCB kudzera pa SMT kaye kenako ndikuviika pulagi, yomwe imakhudza kuyenda bwino komanso zovuta komanso zigawo zina zodziwika bwino.Ngati ntchitoyo siinayimidwe, imayambitsa kuwonongeka kwazinthu kapena kuwonongeka kwazinthu, zimakhudza mtundu wazinthu ndikuwonjezera mtengo wokonza.Choncho, mu PCBA Chip processing, tiyenera kutsatira malamulo oyendetsera ntchito ndi ntchito mosamalitsa malinga ndi zofunika.M'munsimu ndi mawu oyamba.
Malamulo ogwiritsira ntchito PCBA patch processing:
1. Pasakhale chakudya kapena chakumwa m'malo ogwirira ntchito a PCBA.Kusuta ndikoletsedwa.Palibe zinthu zina zosagwirizana ndi ntchitoyi zomwe ziyenera kuyikidwa.Benchi yogwirira ntchitoyo iyenera kukhala yoyera komanso yaudongo.
2. Mu PCBA Chip processing, pamwamba kuti welded sangathe kutengedwa ndi manja opanda kanthu kapena zala, chifukwa mafuta opangidwa ndi manja kuchepetsa weldability ndi mosavuta kutsogolera kuwotcherera zilema.
3. Kuchepetsa ntchito masitepe PCBA ndi zigawo zikuluzikulu kuti osachepera, kuti kupewa ngozi.M'malo ophatikizana omwe magulovu amayenera kugwiritsidwa ntchito, magolovesi odetsedwa amatha kuwononga, motero ndikofunikira kusintha magulovu pafupipafupi.
4. Osagwiritsa ntchito mafuta oteteza khungu kapena zotsukira zomwe zili ndi utomoni wa silikoni, zomwe zingayambitse mavuto pakuwotcha komanso kumamatira kumatira.Chotsukira chokonzekera mwapadera cha PCBA kuwotcherera pamwamba chilipo.
5. Zigawo za EOS / ESD zokhudzidwa ndi PCBA ziyenera kudziwika ndi zizindikiro za EOS / ESD zoyenera kupewa chisokonezo ndi zigawo zina.Kuonjezera apo, pofuna kupewa ESD ndi EOS kuti asawononge zigawo zowonongeka, ntchito zonse, msonkhano ndi kuyesa ziyenera kumalizidwa pa benchi yogwirira ntchito yomwe imatha kuyendetsa magetsi osasunthika.
6. Yang'anani pa EOS / ESD worktable nthawi zonse kuti muwonetsetse kuti akugwira ntchito bwino (anti-static).Zowopsa zamitundu yonse yazigawo za EOS / ESD zitha kuyambitsidwa ndi njira yolakwika yoyambira kapena oxide pagawo lolumikizira.Choncho, chitetezo chapadera chiyenera kuperekedwa ku mgwirizano wa "waya wachitatu" woyambira pansi.
7. Ndi zoletsedwa okwana PCBA, amene adzawononga thupi.Mabakiteriya apadera adzaperekedwa pa msonkhano nkhope ntchito ndi kuikidwa molingana ndi mtundu.
Pofuna kuonetsetsa khalidwe lomaliza la mankhwala, kuchepetsa kuwonongeka kwa zigawo zikuluzikulu ndi kuchepetsa mtengo, m'pofunika mosamalitsa kutsatira malamulo opareshoni ndi ntchito molondola PCBA Chip processing.
