3. Ithebula lokuqhathanisa lemizuzu emithathu: beka phambili lezi zinto ezi-5 uma ukhetha
| Ukuqhathanisa | I-Caster Eqhubayo | I-Caster elwa nokungaguquguquki |
| Ibanga lokumelana (elijwayelekile) | ≤ 10 ⁴ Ω (ukumelana okuphansi) | 10 ⁵ -10 ⁹ Ω (ububanzi bokulahla) |
| Ukukhishwa kwenkokhelo | Isiqondiso esisheshayo kanye nokuvimbela ukuqongelela | Ukuhlakazeka okuhamba kancane, amandla alawulwayo |
| Izidingo zokubeka phansi | Ngokuvamile kuncike kakhulu ezinhlelweni zokufaka umhlabathi/umhlabathi ezisebenzisa ugesi | Izidingo ezijwayelekile ziphansi kakhulu, kodwa izingxenye zokufaka ugesi kusadingeka zigwenywe |
| Inhloso eyinhloko | Ubufakazi bokuqhuma/ukuvimbela ukuqhekeka kwe-ESD (ingozi ephezulu) | Ukuphazamiseka kokungaluthuli/ukungakhiphi uthuli oluncane (ingozi ephakathi nendawo ephansi) |
| Izimboni ezijwayelekile | Ukuqhuma kukawoyela negesi/amakhemikhali/uthuli, i-semiconductor ehlanzekile kakhulu | Ukuthuthwa kwezinsimbi, ifektri ejwayelekile ye-elekthronikhi, ukuphathwa kwegumbi lomshini/iseva |
4. Ukusetshenziswa okuvamile: Khetha okuzinzile kakhulu ngokusekelwe ezingeni lobungozi
1). Izimo ezengeziwe ezinconywayo zama-casters aqhubayo:
Okuvuthayo nokuqhumisayo: ukufutha ngopende, indawo yokugcina izinyibilikisi, iziteshi zensimu kawoyela negesi, izindawo zokusebenzela ezinobungozi bokuqhuma kothuli.
Ukuhlanza/i-semiconductor ephezulu: ukukhiqizwa kwama-chip, ukuhlolwa kokupakisha, imoto ebalulekile yokushintsha indawo yokusebenza ye-ESD.
2). Izimo ezengeziwe ezinconywayo zama-casters alwa nama-static:
Ukuthuthwa kwezinsimbi ezinembile kanye nemishini yezokwelapha: ukunciphisa ukuphazamiseka okuvela ekumuncweni kwe-electrostatic kanye nokukhishwa okuncane.
Ukukhiqizwa okuvamile kwe-elekthronikhi: Izimoto zokushintshana ze-SMT, izimoto ezisetshenziswayo, kanye nokuphathwa kwemishini yegumbi lomshini (ingozi ayibhekwa njengeqhumayo).
5. Uhlu lokuhlola lokukhetha: Bhala lezi zingcezu eziyisithupha zolwazi efomini lokubuza ukuze uqinise ukusebenza kahle kokuxhumana kabili.
1). Izinga lengozi ye-electrostatic: ukuthi ingasha noma iyaqhuma/kungakhathaliseki ukuthi iyidivayisi ezwela izinga le-chip (ukunquma ukuhanjiswa kwamandla kagesi uma kuqhathaniswa nokusatshalaliswa).
2). Ububanzi bokumelana nokuqondiwe: chaza "ukuqhuba/ukusatshalaliswa" kanye nobubanzi obulindelekile, futhi udinga umbiko wokuhlola.
3). Izimo zomhlabathi: ukuthi ngabe kukhona igridi yokudonsa phansi/yokumisa phansi; Ububanzi bomswakama (ugesi omile ubonakala kakhulu ezimweni ezomile kakhulu).
4). Umthamo womthwalo kanye nemvamisa: isisindo esiphelele, umthwalo oguquguqukayo wesondo elilodwa, ibanga/imvamisa yokusunduza yansuku zonke (ukunquma ububanzi besondo, ububanzi besondo, kanye nama-bearings).
5). Isakhiwo nokufakwa: okuqinile/okujwayelekile, ukukhiya kwebhuleki/okuqondisa, isikhala sembobo yokufaka/imbobo/ukuphakama okuphelele/ukusetha.
6). Izidingo zokulungisa: Kungenzeka yini ukuhlanza njalo amabala kawoyela ebusweni besondo, uhlole kabusha ukumelana njalo, bese uhlola isixhumanisi somhlaba.
Isiphetho:
Umehluko phakathi kwama-caster kagesi nama-caster alwa ne-static awukho egameni, kodwa “esihlokweni sokumelana nesixhumanisi somhlaba”. Ezimweni ezinobungozi obukhulu, kubalulekile ukuqeda ngokushesha ukushaja bese ukhetha ukudlulisa amandla; Ngokuvamile, ukulawulwa kwe-static kudinga ukushabalaliswa okuzinzile futhi kufanele kukhethwe izindlela zokulwa ne-static. Ungakhohlwa: Uma isixhumanisi somhlaba sesifakwe i-insulation (amabala kawoyela, izembozo, izingxenye zepulasitiki, ama-bearings angahambisani nokuhambisa), ngisho namasondo amahle kakhulu angase angasebenzi.
