Imiterere y'ibikoresho bya PCB ntabwo ari ikintu uko bishakiye, ifite amategeko amwe agomba gukurikizwa na buri wese.Usibye ibisabwa muri rusange, ibikoresho bimwe bidasanzwe nabyo bifite imiterere itandukanye.
Ibisabwa kugirango ubone ibikoresho
1) Ntabwo hagomba kubaho ibice birenga 3mm 3mm bikikije igikoresho kigoramye / kigabo, kigoramye / gitsindagiye hejuru yumugore, kandi ntihakagombye kubaho ibikoresho byo gusudira hafi 1.5mm;intera kuva kuruhande rutandukanye rwigikoresho gisunika kugeza pin umwobo rwagati wigikoresho gisya ni 2.5 Ntihazabaho ibice biri murwego rwa mm.
2) Ntihakagombye kubaho ibice muri 1mm bikikije igikoresho kigororotse / kigabo, kigororotse / kigore;mugihe inyuma yibikoresho bigororotse / byigitsina gabo, bigororotse / byigitsina gore bigomba gushyirwaho nurupapuro, ntakintu na kimwe kigomba gushyirwa muri 1mm uhereye kumpera yicyatsi Iyo sheath idashyizweho, ntakintu na kimwe kigomba gushyirwa muri 2.5mm kuva mu mwobo.
3) Gucomeka kwizima kwihuza ryubutaka rikoreshwa hamwe nu Burayi bwuburyo bwuburayi, impera yimbere yurushinge rurerure ni 6.5mm yimyenda yabujijwe, naho urushinge rugufi ni imyenda ya 2.0mm yabujijwe.
4) Ipine ndende ya 2mmFB itanga amashanyarazi imwe ya PIN ihuye nigitambaro cya 8mm kibujijwe imbere yumutwe umwe.
Ibisabwa kugirango ubone ibikoresho byubushyuhe
1) Mugihe cyimiterere yibikoresho, komeza ibikoresho byorohereza ubushyuhe (nka capacitori ya electrolytike, oscillator ya kristu, nibindi) kure yubushyuhe bwinshi bushoboka.
2) Igikoresho gishyuha kigomba kuba hafi yikigeragezo kandi kiri kure yubushyuhe bwo hejuru, kugirango bitagira ingaruka kubindi bikoresho bishyushya bihwanye kandi bigatera imikorere mibi.
3) Shira ibice bitanga ubushyuhe kandi birwanya ubushyuhe hafi yumuyaga cyangwa hejuru, ariko niba bidashobora kwihanganira ubushyuhe bwo hejuru, bigomba no gushyirwa hafi yumuyaga, kandi ukitondera kuzamuka mukirere hamwe nubundi bushyuhe ibikoresho nibikoresho byumva ubushyuhe bushoboka Shyira umwanya mubyerekezo.
Ibisabwa bisabwa hamwe nibikoresho bya polar
1) ibikoresho bya THD bifite polarite cyangwa icyerekezo bifite icyerekezo kimwe mumiterere kandi bitunganijwe neza.
2) Icyerekezo cya polarisike ya SMC ku kibaho igomba kuba ihamye uko bishoboka;ibikoresho byubwoko bumwe byateguwe neza kandi byiza.
(Ibice bifite polarite harimo: capacitori ya electrolytike, capacator ya tantalum, diode, nibindi)
Ibisabwa kugirango ubone ibikoresho byo kugurisha
1) Kuri PCBs zifite ibipimo byoherejwe bitarenze 300mm, ibice biremereye ntibigomba gushyirwa hagati ya PCB uko bishoboka kwose kugirango bigabanye ingaruka zuburemere bwibikoresho byacometse kumiterere ya PCB mugihe inzira yo kugurisha, hamwe n'ingaruka zo gucomeka kumurongo.Ingaruka z'igikoresho cyashyizwe.
2) Kugirango byorohereze kwinjiza, igikoresho kirasabwa gutondekwa hafi yimikorere yibikorwa.
3) Icyerekezo kirekire cyibikoresho birebire (nkibikoresho byo kwibuka, nibindi) birasabwa guhuza icyerekezo cyo kohereza.
4) Intera iri hagati yuruhande rwurwobo rwerekana ibicuruzwa byo kugurisha hamwe na QFP, SOP, umuhuza hamwe na BGAs zose zifite ikibanza ≤ 0,65mm kirenze 20mm.Intera nibindi bikoresho bya SMT ni> 2mm.
5) Intera iri hagati yumubiri wigikoresho cyo kugurisha cyanyuze hejuru ya 10mm.
6) Intera iri hagati yuruhande rwibikoresho byogucuruza nu mwobo wohereza ni ≥10mm;intera kuva kuruhande rutanduza ni ≥5mm.
