Kodi mukudziwa kuti ndi malamulo ati omwe ayenera kutsatidwa pokonza PCBA?

Kukupatsani PCBA chidziwitso chatsopano! Bwerani tiwone!

PCBA ndi njira yopangira bolodi ya PCB yopanda kanthu kudzera mu SMT poyamba ndikuyika plug-in, yomwe imakhudza njira zambiri zoyendera komanso zovuta zina. Ngati opareshoniyo sanakonzedwe, zimayambitsa zopunduka kapena kuwonongeka kwa chinthu, zimakhudza mtundu wa malonda ndikuwonjezera mtengo wa kukonza. Chifukwa chake, pokonza za PCBA chip, tiyenera kutsatira malamulo oyendetsera ntchito ndikugwira ntchito mosamalitsa malinga ndi zofunikira. Lotsatira ndi mawu oyamba.

Malamulo a ntchito ya PCBA chigamba:

1. Pasakhale chakudya kapena zakumwa m'dera logwirira ntchito la PCBA. Kusuta nkoletsedwa. Palibe sundries osagwira ntchito ayenera kuyikidwa. Bokosilo liyenera kukhala loyera komanso laudongo.

2. Pakukonzekera kwa PCBA Chip, mawonekedwe oti awotcheredwe sangatenge ndi manja kapena zala, chifukwa mafuta omwe amatulutsidwa ndi manja amachepetsa kuwotcherera ndikupangitsa kuti pasakhale zovuta kuwotcherera.

3. Chepetsani magwiridwe antchito a PCBA ndi zinthu zochepa, kuti mupewe ngozi. M'malo ochitira msonkhano momwe magolovesi amayenera kugwiritsidwa ntchito, magolovu osadetsedwa amatha kuyambitsa kuipitsidwa, kotero, magolovesi ofunika nthawi zonse amafunika.

4. Musagwiritse ntchito mafuta oteteza khungu kapena zotsekemera zokhala ndi utomoni wa silicone, womwe ungayambitse mavuto pakulunga kophatikizana. Chotchera chokonzekera mwapadera cha PCBA chowotchera chilipo.

5. Zida zowona za EOS / ESD ndi PCBA ziyenera kuzindikirika ndi zilembo zoyenera za EOS / ESD kuti mupewe kusokonezeka ndi zinthu zina. Kuphatikiza apo, pofuna kupewa ESD ndi EOS kuti isaike pangozi zinthu zofunika, ntchito zonse, msonkhano ndi kuyeserera ziyenera kumalizidwa pabokosi la ntchito lomwe limatha kuwongolera magetsi osasunthika.

6. Onani nthawi yolumikizira ya EOS / ESD kuti muwone ngati ikugwira bwino ntchito (anti-static). Mitundu yonse yamavuto a zigawo za EOS / ESD imatha kuchitika chifukwa cha njira yolakwika yokhazikikira kapena oxide mu gawo la cholumikizira. Chifukwa chake, chitetezo chapadera chimayenera kuperekedwa kwa olumikizana ndi "wachitatu waya" wodwala oyikira.

7. Ndizoletsedwa kutsekemera PCBA, zomwe zingawononge thupi. Mabakiteriya apadera adzaperekedwera pamsonkhano wogwira ntchito ndikuwayika malinga ndi mtunduwo.

Kuti muwonetsetsetsetsetsetsetsetsetsetsetsetseg wots zonse wa zinthu, kuchepetsa kuwonongeka kwa zigawo zina ndikuchepetsa mtengo, ndikofunikira kutsatira malamulo awa ndikugwirira ntchito molondola pakukonzanso kwa PCBA chip.

Mkonzi ali pano lero. Kodi mwamva?
