Mu gishushanyo cya PCB, imiterere y'ibigize ni imwe mu miyoboro y'ingenzi. Kuri ba injeniyeri benshi ba PCB, uburyo bwo gushyira ibice muburyo bunoze kandi neza bifite ibipimo byihariye. Twavuze muri make ubuhanga bwo gutunganya, hafi 10 ikurikira Imiterere yibikoresho bya elegitoronike igomba gukurikizwa!

Uruganda rwumuzunguruko

1. Kurikiza ihame ryimiterere ya "binini mbere, hanyuma bito, bigoye mbere, byoroshye mbere", ni ukuvuga ibice byingenzi byumuzingi nibice byingenzi bigomba gushyirwaho mbere.

2. Igishushanyo mbonera cyo guhagarika igishushanyo kigomba kwerekanwa mumiterere, kandi ibice byingenzi bigomba gutondekwa ukurikije ibimenyetso nyamukuru byerekana.

3. Gutondekanya ibice bigomba kuba byoroshye gukemura no kubungabunga, ni ukuvuga ko ibice binini bidashobora gushyirwa hafi yibice bito, kandi hagomba kubaho umwanya uhagije hafi yibice bigomba gukemurwa.

4. Kubice byumuzunguruko byuburyo bumwe, koresha imiterere ya "symmetrical" bisanzwe bishoboka.

5. Hindura imiterere ukurikije ibipimo byo gukwirakwiza kimwe, hagati yuburinganire bwimbaraga, nuburyo bwiza.

6. Ubwoko bumwe bwibikoresho byo gucomeka bigomba gushyirwa mu cyerekezo kimwe mu cyerekezo cya X cyangwa Y. Ubwoko bumwe bwibice bya polarize bigomba kandi guharanira guhuza icyerekezo cya X cyangwa Y kugirango byorohereze umusaruro nubugenzuzi.

7. Ibikoresho byo gushyushya bigomba gukwirakwizwa muburyo bworoshye kugirango byoroherezwe ubushyuhe bwa mashini na mashini yose. Ibikoresho byoroshye ubushyuhe butari ikintu cyerekana ubushyuhe bugomba kubikwa kure yibice bitanga ubushyuhe bwinshi.

8. Imiterere igomba kuba yujuje ibisabwa bikurikira uko bishoboka: guhuza byose ni bigufi bishoboka, kandi umurongo wingenzi wibimenyetso ni ngufi; Umuvuduko mwinshi, ibimenyetso binini bigezweho hamwe nubushyuhe buke, ibimenyetso bya voltage nkeya bitandukanijwe rwose; ibimenyetso bisa nibimenyetso bya digitale biratandukanye; ikimenyetso cyumuvuduko mwinshi Tandukanya nibimenyetso bike; intera yibice byinshi-bigomba kuba bihagije.

9. Imiterere ya capacitor ya decoupling igomba kuba yegeranye hashoboka kuri pin itanga amashanyarazi ya IC, kandi ikizunguruka hagati yacyo n'amashanyarazi n'ubutaka bigomba kuba bigufi.

10. Mu bice bigize ibice, hagomba kwitabwaho gushyira ibikoresho ukoresheje amashanyarazi amwe hamwe bishoboka kugirango byoroherezwe gutandukanya amashanyarazi.
