Mu gishushanyo mbonera cyubuyobozi bwa PCB, igishushanyo cya anti-ESD cya PCB gishobora kugerwaho hifashishijwe ibice, imiterere ikwiye hamwe nogukoresha no gushiraho. Mugihe cyo gushushanya, ubwinshi bwibishushanyo mbonera bishobora kugarukira gusa kongeramo cyangwa gukuramo ibice binyuze mubuhanuzi. Muguhindura imiterere ya PCB hamwe nu nsinga, ESD irashobora gukumirwa neza.
Amashanyarazi ahamye ya PCB aturuka mumubiri wumuntu, ibidukikije ndetse no mubikoresho byubuyobozi bwamashanyarazi PCB bizangiza ibintu bitandukanye kuri chip ya semiconductor neza, nko kwinjira mubice bito cyane; Ibyangiritse ku irembo ryibigize MOSFET na CMOS; CMOS PCB ikoporora imbarutso; Ihuriro rya PN hamwe na sisitemu ngufi ihindagurika kubogama; Ikibaho kigufi cyiza PCB ikoporora ikibaho kugirango ihuze PN ihuza; Urupapuro rwa PCB rushonga umugurisha cyangwa insinga ya aluminium mugice cya PCB igice cyibikoresho bikora. Kugirango ukureho amashanyarazi (ESD) kwangirika no kwangiza ibikoresho bya elegitoroniki, birakenewe gufata ingamba zitandukanye za tekiniki kugirango birinde.
Mu gishushanyo mbonera cyubuyobozi bwa PCB, igishushanyo mbonera cya anti-ESD cya PCB gishobora kugerwaho hifashishijwe imiterere nuburyo bukwiye bwo gukoresha insinga ya PCB no kuyishyiraho. Mugihe cyo gushushanya, ubwinshi bwibishushanyo mbonera bishobora kugarukira gusa kongeramo cyangwa gukuramo ibice binyuze mubuhanuzi. Muguhindura imiterere ya PCB no kuyobora, ikibaho cyo gukoporora PCB kirashobora gukumirwa neza kububiko bwa PCB PCD. Hano hari bimwe mubisanzwe byo kwirinda.
Koresha ibice byinshi bya PCB bishoboka, ugereranije na PCB ifite impande ebyiri, indege yubutaka nindege yingufu, hamwe nibimenyetso byegeranye byegeranye byumurongo wubutaka birashobora kugabanya uburyo busanzwe bwo guhuzagurika no guhuza inductive, kugirango bigere kuri 1 / 10 kugeza 1/100 cya PCB impande zombi. Gerageza gushyira buri kimenyetso cyerekana iruhande rwimbaraga cyangwa hasi. Kuri PC-yuzuye cyane PCBS ifite ibice byombi hejuru no hepfo, bifite imirongo migufi ihuza kandi ahantu henshi huzura, urashobora gutekereza gukoresha umurongo w'imbere. Kubice bibiri PCBS, amashanyarazi akomatanyirijwe hamwe hamwe na gride yubutaka irakoreshwa. Umugozi w'amashanyarazi wegereye hasi, hagati y'imirongo ihanamye kandi itambitse cyangwa yuzuza ahantu, kugirango uhuze byinshi bishoboka. Uruhande rumwe rwa gride ya PCB ingano iri munsi cyangwa ingana na 60mm, niba bishoboka, ingano ya gride igomba kuba munsi ya 13mm
Menya neza ko urupapuro rwumuzingi rwa PCB rworoshye nkuko bishoboka.
Shira abahuza bose kuruhande rushoboka.
Niba bishoboka, menyekanisha ingufu za PCB umurongo uva hagati yikarita kandi kure y ahantu hashobora kwibasirwa ningaruka za ESD.
Kuri PCB zose ziri munsi yumuhuza uva muri chassis (zikunda kwangirika kwangirika kwa ESD kububiko bwa kopi ya PCB), shyira chassis nini cyangwa polygon yuzuye hasi hanyuma ubihuze hamwe nu mwobo mugihe kingana na 13mm.
Shira urupapuro rwa PCB rushyira umwobo kuruhande rwikarita, hanyuma uhuze hejuru no hepfo yurupapuro rwurupapuro rwa PCB rutambutse ruzengurutse umwobo uzamuka kugeza hasi ya chassis.
Mugihe cyo guteranya PCB, ntukoreshe uwagurishije hejuru cyangwa hepfo urupapuro rwa PCB. Koresha imigozi yubatswe mumashanyarazi ya PCB kugirango ugere kumikoranire hagati yurupapuro rwa PCB / ingabo mumashanyarazi cyangwa inkunga kubutaka.
“Agace kamwe” kamwe kagomba gushyirwaho hagati yubutaka bwa chassis nubutaka bwumuzingi wa buri cyiciro; Niba bishoboka, komeza umwanya kuri 0.64mm.
Hejuru no hepfo yikarita hafi yikibaho cyo gukoporora PCB, uhuze chassis hamwe nubutaka bwumuzingi hamwe ninsinga z'ubugari bwa 1.27mm kumurongo winsinga ya chassis buri 100mm. Iyegeranye niyi ngingo ihuza, udupapuro two kugurisha cyangwa umwobo wo gushiraho ushyirwa hagati ya chassis hasi nu rupapuro rwumuzingi urupapuro rwa PCB. Ihuza ryubutaka rirashobora gucibwa gufungura umuhoro kugirango ugume ufunguye, cyangwa gusimbuka hamwe nisaro ya magneti / capacitori yumurongo mwinshi.
Niba ikibaho cyumuzunguruko kitazashyirwa mubikoresho byicyuma cyangwa igikoresho cyo gukingira urupapuro rwa PCB, ntukoreshe imiti igurisha insinga zo hejuru no hepfo insinga zubutaka bwumuzunguruko, kugirango zishobore gukoreshwa nka ESD arc isohora electrode.
Gushiraho impeta izenguruka kumurongo ukurikira PCB:
(1) Usibye kumpera yicyuma gikoporora PCB na chassis, shyira inzira yimpeta izengurutse impande zose.
(2) Menya neza ko ibice byose birenga 2,5mm z'ubugari.
(3) Huza impeta na mwobo buri 13mm.
.
. Umuzunguruko udafunze impande zombi ugomba guhuzwa nubutaka bwimpeta, ubutaka bwimpeta ntibushobora gutwikirwa n’abagurisha ibicuruzwa, kugirango impeta ibashe gukora nkinkoni isohora ESD, kandi byibuze icyuho cya 0.5mm kigashyirwa kuri runaka umwanya kumurongo wimpeta (ibice byose), bishobora kwirinda ikibaho cya kopi ya PCB kugirango kibe kizunguruka kinini. Intera iri hagati yicyuma cyerekana ibimenyetso nubutaka bwimpeta ntigomba kuba munsi ya 0.5mm.
