3. Itheyibhile yokuthelekisa yemizuzu emithathu: beka phambili ezi zinto zi-5 xa ukhetha
| Uthelekiso | Umqhubi we-Conductive | I-Caster echasene nokuqina |
| Uluhlu lokuxhathisa (oluqhelekileyo) | ≤ 10 ⁴ Ω (ukuxhathisa okuphantsi) | 10 ⁵ -10 ⁹ Ω (uluhlu lokulahla) |
| Ukukhululwa kwentlawulo | Isikhokelo esikhawulezileyo kunye nokuthintela ukuqokelelwa | Ukusasazwa kancinci, amandla alawulwayo |
| Iimfuneko zokumisa umhlaba | Ngokwesiqhelo ixhomekeke kakhulu kwiinkqubo zomhlaba/zomhlaba eziqhubayo | Iimfuneko ngokubanzi ziphantsi kakhulu, kodwa izahlulo zokukhusela ubushushu zisafuneka ziphetshwe |
| Injongo ephambili | Ubungqina bokuqhuma/ukuthintela ukuqhekeka kwe-ESD (umngcipheko ophezulu) | Ukuphazamiseka kokukhupha uthuli/ukuphazamiseka kokukhupha izinto ezincinci (umngcipheko ophakathi nophantsi) |
| Amashishini aqhelekileyo | Ukuqhuma kweoyile kunye negesi/iikhemikhali/uthuli, i-semiconductor ecocekileyo kakhulu | Ukuthuthwa kwezixhobo, umzi-mveliso we-elektroniki ngokubanzi, igumbi lomatshini/ukuphathwa kweseva |
4. Indlela eqhelekileyo yokusetyenziswa: Khetha uzinzile ngakumbi ngokusekelwe kwinqanaba lomngcipheko
1). Ezinye iimeko ezicetyiswayo zee-casters eziqhubayo:
Iyatsha kwaye iqhumise: ukutshiza ipeyinti, indawo yokugcina isinyibilikisi, izikhululo zeoyile kunye negesi, iindawo zokusebenzela ezinobungozi bokuqhuma kothuli.
Ukucoca/i-semiconductor ephezulu: ukwenziwa kweetships, uvavanyo lokupakisha, isithuthi esibalulekileyo sokujika kwe-ESD workstation.
2). Ezinye iimeko ezicetyiswayo ze-anti-static casters:
Ukuthuthwa kwezixhobo ezichanekileyo kunye nezixhobo zonyango: ukunciphisa ukuphazamiseka okuvela ekutsalweni kwe-electrostatic kunye nokukhutshwa kwe-micro discharge.
Ukuveliswa kwezinto nge-elektroniki ngokubanzi: Izithuthi ze-SMT ezitshintshayo, izithuthi ezincedisayo, kunye nokuphathwa kwezixhobo zegumbi loomatshini (umngcipheko awuchazwa njengoqhushumbisi).
5. Uluhlu lokuhlola ukhetho: Bhala ezi nkcukacha zi-6 kwifomu yophando ukuze uqinise ukusebenza kakuhle konxibelelwano
1). Inqanaba lomngcipheko we-electrostatic: nokuba iyatsha okanye iyaqhuma/nokuba sisixhobo esibuthathaka kwinqanaba le-chip (ukumisela ukuhanjiswa kombane ngokuchasene nokusasazwa).
2). Uluhlu lokumelana neethagethi: chaza "ukuqhuba/ukusasazwa" kunye noluhlu olulindelekileyo, kwaye ufune ingxelo yovavanyo.
3). Iimeko zomhlaba: nokuba kukho umgangatho/igridi yokumisa umhlaba eqhuba umbane; Uluhlu lokufuma (umbane ongashukumiyo ubonakala ngakumbi kwiimeko ezomileyo kakhulu).
4). Umthamo womthwalo kunye nokuphindaphinda: ubunzima obupheleleyo, umthwalo oguquguqukayo wevili elinye, umgama/ukuphindaphinda kokutyhala imihla ngemihla (ukumisela ububanzi bevili, ububanzi bevili, kunye neebheringi).
5). Ulwakhiwo kunye nofakelo: oluzinzileyo/oluqhelekileyo, isitshixo sebhuleki/esibhekisa kwicala, isithuba semingxuma yokufakelwa/isithuba sokuvula/ubude obupheleleyo/i-offset.
6). Iimfuno zolondolozo: Ngaba kunokwenzeka ukucoca rhoqo amabala eoyile kumphezulu wevili, ukuvavanya kwakhona ukumelana rhoqo, kwaye ujonge ikhonkco lomhlabathi.
Isiphelo:
Umahluko phakathi kwee-casters zombane kunye nee-casters ezichasene ne-static awukho kwigama, kodwa kwi-"resistance level kunye ne-grounding link". Kwiimeko ezinobungozi obukhulu, kubalulekile ukukhupha ngokukhawuleza itshaja kwaye ukhethe i-conductivity; Ngokubanzi, ulawulo oluzinzileyo lufuna ukuchithwa okuzinzileyo kwaye kufuneka kukhethwe amanyathelo okulwa ne-static. Ungalibali: Nje ukuba ikhonkco lokumisa ligqunywe (amabala eoli, ii-coating, ii-partitions zeplastiki, ii-bearings ezingezizo ezihambisa i-conductive), kwanamavili angcono anokungaphumeleli.
