Amategeko shingiro yimiterere ya PCB

2. Ibigize nibikoresho bigomba gushyirwaho muri 1,27mm bikikije umwobo udashyirwaho nkumwobo uhagaze nu mwobo usanzwe, kandi nta bice bigomba gushyirwaho muri 3.5mm (kuri M2.5) na 4mm (kuri M3) bikikije umwobo nka imigozi;
3. Irinde gushyira vias munsi yibice nka résistoriste itambitse itambitse, inductors (plug-ins), hamwe na capacitori ya electrolytike kugirango wirinde imiyoboro migufi hagati ya vias nigikonoshwa nyuma yo kugurisha umuraba;
4. Intera iri hagati yikigize ninkombe yikibaho ni 5mm;
5. Intera iri hagati yinyuma yububiko bwimbere hamwe ninyuma yikintu cyegeranye kirenze 2mm;
6. Ibice by'ibishishwa by'ibice n'ibice by'icyuma (agasanduku gakingira, n'ibindi) ntibishobora gukora ku bindi bice, kandi ntibishobora kuba hafi y'imirongo yacapishijwe na padi, kandi intera igomba kuba irenze 2mm.Ingano yimyobo ihagaze, imyobo yihuta yo kwishyiriraho, imyobo ya elliptique nindi myobo ya kare mu isahani irenze 3mm uhereye kumpera yisahani;
7. Ikintu cyo gushyushya ntigishobora kuba hafi yinsinga nubushyuhe;ibintu bishyushya cyane bigomba kugabanwa neza;
8. Umuyoboro wamashanyarazi ugomba gutondekanya hafi yicyapa cyacapwe bishoboka, kandi aho bisi ya bisi ihurira nu mashanyarazi igomba gutondekwa kuruhande rumwe.Byakagombye kwitonderwa bidasanzwe kugirango udategura amashanyarazi hamwe nandi masoko yagurishijwe hagati yabahuza, kugirango byoroherezwe kugurisha ayo masoko hamwe nu muhuza, no gushushanya no guhambira insinga z'amashanyarazi.Umwanya utondekanya amashanyarazi ya socket hamwe nu gusudira bigomba gusuzumwa kugirango byoroherezwe kwinjiza no gukuraho amashanyarazi;
9. Gutegura ibindi bice:
Ibice byose bigize IC bihujwe ku buryo bumwe, polarite yibice bya polar iragaragara neza, kandi polarite iranga ikibaho kimwe cyacapwe ntigomba kurenza ibyerekezo bibiri.Iyo ibyerekezo bibiri bigaragara, ibyerekezo byombi biratandukanye;
10. Amashanyarazi ku kibaho agomba kuba yuzuye.Iyo itandukaniro ryubucucike ari rinini cyane, rigomba kuzuzwa na feri y'umuringa mesh, kandi mesh igomba kuba irenze 8mil (cyangwa 0.2mm);
11. Ntihakagombye kubaho kunyura mu mwobo ku ipaki, kugirango wirinde gutakaza paste yo kugurisha no gutuma ibice bigurishwa.Imirongo yingenzi yibimenyetso ntabwo yemerewe kunyura hagati ya sock pin;
12. Ipamba ihujwe ku buryo bumwe, icyerekezo cy'inyuguti ni kimwe, kandi icyerekezo cyo gupakira ni kimwe;
13. Kubikoresho bifite polarite, icyerekezo cya polarite iranga ikibaho kimwe kigomba kuba gihamye gishoboka.

Amategeko yo Kuzenguruka PCB

1. Mu gace aho insinga zitarenze cyangwa zingana na 1mm kuva ku nkombe za PCB, no muri 1mm ikikije umwobo uzamuka, birabujijwe gukoresha insinga;
2. Umurongo w'amashanyarazi ugomba kuba mugari bishoboka kandi ntugomba kuba munsi ya 18mil;ubugari bwumurongo wibimenyetso ntibugomba kuba munsi ya 12mil;cpu iyinjiza nibisohoka imirongo ntigomba kuba munsi ya 10mil (cyangwa 8mil);intera y'umurongo ntigomba kuba munsi ya 10mil;
3. Ibisanzwe binyuze ntabwo biri munsi ya 30mil;
4. Babiri kumurongo: pad 60mil, aperture 40mil;
1 / 4W résistoriste: 51 * 55mil (0805 hejuru yubuso);iyo kumurongo, padi ni 62mil, na aperture ni 42mil;
Imashanyarazi idafite amashanyarazi: 51 * 55mil (0805 hejuru yubuso);iyo ucometse neza, padi ni 50mil, na aperture ni 28mil;
5. Menya ko insinga z'amashanyarazi hamwe ninsinga zubutaka bigomba kuba bifite radiyo ishoboka, kandi insinga yikimenyetso ntigomba gufungurwa.
