Ezimweni ezifana nama-semiconductor kagesi, izinsimbi zokunemba, amakhemikhali kaphethroli, kanye nama-workshop othuli, ukuqongelela kukagesi ongaguquki kungabangela izinhlobo ezimbili zezinkinga: enye ukuwohloka kwezingxenye ezizwelayo ngokukhishwa kwe-electrostatic (ESD), kanti enye ingozi yokushisa ezindaweni ezivuthayo neziqhumayo. Zombili iziqhumane eziqhubayo kanye neziqhumane ezilwa ne-static zisetshenziselwa "ukuphathwa kweshaja", kodwa imigomo kanye nezindlela zokusebenzisa zihlukile. Ukukhetha okungalungile kungaholela ekuhlulekeni kokulawula ubungozi.
Okokuqala, ake siphethe ngokuthi: ungayikhetha kanjani efanele ngokushesha?
Uma kukhulunywa ngezingozi ezivuthayo neziqhumayo (i-solvent, uwoyela negesi, izingozi zokuqhuma kothuli) noma izingozi ze-ESD ezihlanzekile kakhulu/ezisezingeni le-chip, kufanele kunikezwe kuqala “ama-casters aqhubayo” (adinga ukushajwa ngokushesha).
Ngokuyinhloko ukunciphisa ukumuncwa kwe-electrostatic nokugwema ukuphazamiseka okuncane kokukhipha (ngokuvamile ezimbonini zikagesi kanye nokuthuthwa kwezinsimbi): khetha “ama-anti-static casters” (ukuvumela ukuthi amashaja aphele kancane).
Kungakhathaliseki ukuthi iyiphi ekhethiwe: hlola njalo ukuthi 'isixhumanisi sokusekela' siphelele yini, ngaphandle kwalokho ngisho namapharamitha amahle kakhulu angase ahluleke.
1. Umehluko oyinhloko: Imigomo ehlukene → Amabanga ahlukene okumelana → Isivinini sokukhishwa esihlukile
1) I-Caster Eqhuba Umoya
Umgomo: Susa ngokushesha amacala akhiqizwa yidivayisi/umzimba womuntu, ugweme ukukhishwa ngokushesha ngemva kokuqongelela.
Ukuqaliswa: Ngokwakha indlela yokumelana ephansi phakathi kwezinto eziqhubayo kanye nezakhiwo zensimbi, amashaji afakwa ohlelweni lomhlabathi/lokumisa.
Ukumelana okuvamile: Ukumelana kwesekethe kuvame ukuba yi-≤ 10 ⁴ Ω (izindinganiso/izindlela zokulinganisa ezahlukene zingahluka, sicela ubheke umbiko wokuhlola ukuze uthole ukunemba).
Isivinini sokukhishwa: ngokushesha (kuseduze "nokukhishwa okusheshayo").
2) I-ESD/i-Dissipative Caster
Inhloso: Ukucindezela ukuqongelela kweshaja, ukulawula amandla kagesi aqinile ngaphakathi kobubanzi obuphephile, kanye nokunciphisa izinkinga zokukhishwa okuncane kanye nokuqoqwa kothuli.
Ukusetshenziswa: Sebenzisa izinto/izembozo ezilahlayo ukuze uvumele amashaji ukuthi “akhululeke kancane” kunokuba ulandele ukumelana okuphansi kakhulu.
Ukumelana okuvamile: ikakhulukazi ebangeni lika-10 ⁵ -10 ⁹ Ω (ngokuvamile ezingeni lika-10 ⁶ -10 ⁸ Ω, kusabhekwa umbiko wokuhlolwa).
Isivinini sokukhishwa: kancane (uhlobo lokusabalalisa).
2. Izinto kanye nesakhiwo: Ukuqhuba kudinga "indlela", i-anti-static idinga "ukumelana okulawulwayo"
1). Izindlela ezivamile zama-caster aqhubayo:
Umzimba wesondo: Isondo le-PU/lensimbi eliqhubayo elisebenzisa irabha/eliqhubayo (elingavamile), ngokuvamile litholakala ngokumelana okuphansi ngokusebenzisa izigcwalisi eziqhubayo ezifana nomnyama wekhabhoni.
Ibhulakhethi kanye nesixhumi: Amabhulakhethi ensimbi cishe azokwakha indlela eyinhloko eqhuba ugesi, kanti amanye azoklanywa ngokuxhumana okuphansi ukuqinisekisa ukuthi axhumana nomhlabathi oqhuba ugesi.
Amaphuzu abalulekile: Amasondo, amabhuleki, imishini, kanye nomhlabathi kumele kuxhunywe (ukumelana kokuthinta akumele “kucinywe”).
2). Izindlela ezivamile zama-anti-static casters:
Umzimba wesondo: i-PU/irabha/PP elahlayo, njll., okuqinisa ukumelana okuphakathi ngokusebenzisa ama-anti-static agents noma ama-dissipative fillers.
Ibhulakhethi: Ngokuvamile akudingeki umklamo owengeziwe wokuhambisa umoya, kodwa izingxenye zokufaka umoya (ezifana nama-plastic pad, amafilimu opende obukhulu, imikhono yeshafti efakwe umoya, njll.) kufanele zigwenywe.
Iphuzu eliyinhloko: Akukhona ukuthi uma izinto ziqhuba kakhulu, kungcono, kodwa kunalokho ukuthi ukumelana kufanele kulawulwe ngaphakathi kwebanga elingakhipha ngaphandle kokusheshisa kakhulu.
