Asanayitanitse gulu la mayunitsi 10,000, ogulitsa ayenera kuchita pulogalamu yoyesera yapafupi yokhala ndi makontena 100 mpaka 500. Gawo loyeserali limalola gulu logwira ntchito kutsimikizira momwe makontena amagwirira ntchito m'mikhalidwe yeniyeni—kuyesa momwe amagwirizanirana ndi magalimoto oyendera madera, momwe amagwirizanirana bwino ndi zida zodziyimira pawokha, komanso ngati katundu wa ESD akupitirirabe m'malo enieni oyendera. Deta yomwe yasonkhanitsidwa panthawi yoyendetsa ndege imatsimikizira kuti kusintha kulikonse kofunikira pa kayendetsedwe ka zinthu mkati kapena njira zoyendetsera zinthu kupangidwa asanapereke ndalama zambiri.

Njira zoyendetsera bwino kunyamula katundu ndi kusunga katundu m'nyumba zosungiramo katundu

Kukhazikitsa njira zoyendetsera zinthu zonyamula ndi zosungira n'kofunika kwambiri kuti ziwiya zisawonongeke komanso kuti zitetezedwe nthawi zonse.

Mfundo Zofunika Kwambiri

• Kugula zinthu zambiri komanso kugawa zinthu kumabweretsa zotsatira zabwino pa mabokosi otumizira zinthu zamagetsi
• Mafotokozedwe, kutsata malamulo, ndi mawu amalonda omwe ogula ayenera kutsimikizira
• Malangizo othandiza kwa ogulitsa ndi magulu ogula zinthu

Mafunso Ofunsidwa Kawirikawiri

N’chifukwa chiyani mumagwiritsa ntchito zotengera zopindika zosagwirizana ndi static pokonza zinthu za semiconductor?

Amaphatikiza chitetezo cha ESD, kukana kugwedezeka, ndi mphamvu yogwiritsidwanso ntchito. Mapangidwe opindika amachepetsanso kuchuluka kwa zinthu zopanda kanthu zomwe zimabwezedwa, zomwe zimathandiza mafakitale ndi ma OEM kuchepetsa zinyalala zonyamula katundu ndi zolongedza.

Ndi mitundu iti ya ESD yomwe nthawi zambiri imakhala yoyenera mabokosi otumizira zamagetsi?

Pakunyamula zinthu zolemera kwambiri, zinthu zotayira pafupifupi 10^5 mpaka 10^11 ohms nthawi zambiri zimakondedwa chifukwa zimawongolera mphamvu yamagetsi mosatekeseka popanda kutulutsa mwadzidzidzi.

Kodi zotengera zapulasitiki zopindika ndi zabwino kuposa mabokosi okhala ndi zinyalala m'zipinda zoyera?

Inde. Zidebe zotsukira za HDPE kapena PP zotsukira mpweya zimataya tinthu tating'onoting'ono, zimatha kutsukidwa mobwerezabwereza, ndipo ndizoyenera kugwiritsidwa ntchito ndi ISO Class 5 mpaka 7 kuposa kulongedza zinthu zomangira.

Ndi mapulogalamu ati amagetsi omwe amagwirizana bwino ndi zotengera zazikulu za ESD zomwe zimapindika?

Ndi abwino kwambiri potumiza ma wafer pod, kuyenda kwa PCBA, komanso kutumiza ma ECU kapena ma BMS ambiri m'maunyolo ogulitsa omwe amatsekedwa komanso kubweza katundu pafupipafupi.

Ndi zinthu ziti zomwe ogula ayenera kuyerekeza m'mabokosi akuluakulu otumizira zinthu zamagetsi?

Yang'anani momwe ESD ikuyendera, momwe chipinda chotsukira chikugwirizana, kuchuluka kwa katundu, kuchuluka kwa mapini, kukhazikika kwa mapazi, zosankha zamtundu wa dunnage, ndi zinthu zolowera monga zitseko zogwetsera kuti musankhe mzere.
