M'kati mwa PCBA processing ndi kupanga, m'badwo wa magetsi malo amodzi ndi zambiri sizingalephereke, ndipo pali zambiri mwatsatanetsatane mbali zamagetsi pa bolodi PCBA, ndipo zigawo zambiri ndi tcheru kwambiri voteji.Zowopsa zomwe zili pamwamba pa magetsi ovotera zimatha kuwononga zigawozi.Komabe, n'zovuta kufufuza bolodi PCBA kuonongeka ndi malo amodzi magetsi sitepe ndi sitepe pa kuyezetsa zinchito.Chinthu chovulaza kwambiri ndi chakuti bolodi la PCBA likadali labwino pamene likudziwika, koma pali vuto m'manja mwa wogwiritsa ntchito, zomwe sizimangoyambitsa zovuta kwa wogwiritsa ntchito, komanso zimakhudza mtundu wa kampaniyo ndi zabwino.Choncho, chitetezo electrostatic n'kofunika kwambiri pa PCBA processing.
Njira yodzitetezera yokhazikika
Popanga zinthu zamagetsi, pali mfundo ziwiri zofunika kwambiri zoteteza magetsi osasunthika: imodzi ndikuletsa kudzikundikira kwa magetsi osasunthika m'malo omwe magetsi osasunthika atha "Kutulutsa" kuti athetse kudzikundikira kwa magetsi osasunthika ndikuwongolera mkati mwa malo otetezeka. ;chachiwiri ndikuchotsa mwachangu, mosamala komanso mogwira mtima chiwongolero chokhazikika chomwe chapangidwa kale, ndiko kuti, kuchitapo kanthu pakudzikundikira komwe kulipo kuti chiwonongeko mwachangu, nthawi yomweyo "kutuluka".
Chifukwa chake, pachimake pachitetezo chamagetsi pakupanga zinthu zamagetsi ndi "static kuchotsa" ndi "static grounding".
1. Magetsi osasunthika pa kondakitala amatha kuyatsa mbali zomwe mwina kapena zidapanga kale magetsi osasunthika, kutulutsa magetsi osasunthika munthawi yake, ndikugwiritsa ntchito chowunikira kuti azindikire momwe akuyambira.
2. Kwa magetsi osasunthika pa insulator, popeza mtengowo sungathe kuyenda pa insulator, mtengo wa static sungathe kuchotsedwa ndi pansi, koma ukhoza kuyendetsedwa ndi njira zotsatirazi.
Gwiritsani ntchito chofufumitsa cha ion.Kukupiza ion kumatha kupanga ma ion abwino ndi oyipa kuti achepetse magetsi osasunthika a gwero lokhazikika.Amagwiritsidwa ntchito m'malo omwe magetsi osasunthika sangathe kutulutsidwa kudzera pansi, monga malo komanso pafupi ndi mutu wa makina oyika.Kugwiritsa ntchito fani ya ion kuchotsa magetsi osasunthika nthawi zambiri kumakhala ndi anti-static effect.
Sungani chinyezi cha chilengedwe.Kuwonjezeka kwa chinyezi kumatha kuonjezera ma conductivity a pamwamba pa zinthu zopanda conductive, kotero kuti zinthu sizili zophweka kudziunjikira magetsi osasunthika.M'malo owopsa okhala ndi magetsi osasunthika, njira ikaloleza, chonyowa chimatha kukhazikitsidwa kuti chisinthe chinyezi cha chilengedwe.Mwachitsanzo, m'mafakitale kumpoto, magetsi osasunthika amatha kupangidwa chifukwa cha chinyezi chochepa.Kugwiritsa ntchito njira za humidification kungachepetse kuthekera kwa magetsi osasunthika.Njirayi ndiyothandiza komanso yotsika mtengo.
