1. kumurongo nini, bigira ingaruka kumikorere yumuzunguruko. Ubugari bwumurongo ni bugari cyane, ubwinshi bwinsinga ntabwo buri hejuru, ikibaho cyubuyobozi cyiyongera, usibye kongera ibiciro, ntabwo bifasha miniaturizasi. Niba umutwaro uriho ubarwa nka 20A / mm2, mugihe ubunini bwumuringa wambaye umuringa ari 0.5 MM, (mubisanzwe ni byinshi), umutwaro wubu wa 1MM (hafi 40 MIL) ubugari bwumurongo ni 1 A, ubugari bwumurongo rero ifatwa nka 1-2.54 MM (40-100 MIL) irashobora kuzuza ibisabwa muri rusange. Umugozi wubutaka hamwe nu mashanyarazi ku kibaho cy’ibikoresho bifite ingufu nyinshi birashobora kwiyongera uko bikwiye ukurikije ingano y’amashanyarazi. Kumashanyarazi make ya sisitemu, kugirango tunonosore insinga, ubugari ntarengwa bwumurongo burashobora guhazwa no gufata 0.254-1.27MM (10-15MIL). Mubibaho bimwe byumuzunguruko, umugozi wamashanyarazi. Umugozi wubutaka urabyimbye kuruta insinga yikimenyetso.

2: Umwanya utandukanijwe: Iyo ari 1.5MM (hafi 60 MIL), kurwanya insulasiyo hagati yumurongo birenze 20 M ohm, kandi n’umuvuduko ntarengwa uri hagati yumurongo urashobora kugera kuri 300 V. Iyo intera yumurongo ari 1MM (40 MIL) . . Mumuzunguruko muto wa voltage, nka sisitemu yumuzunguruko wa sisitemu, ntabwo ari ngombwa gutekereza kumashanyarazi yamenetse, nkuko inzira ndende itanga umusaruro, irashobora kuba nto cyane.

3. Ibisubizo mukugabanuka kwifata rya padi. Biroroshye kugwa, umwobo uyobora ni muto cyane, kandi gushyira ibice biragoye.

4: Shushanya umuzenguruko wumuzunguruko: Intera ngufi hagati yumurongo wumupaka nigice pin pin ntishobora kuba munsi ya 2MM, (muri rusange 5MM irumvikana) ubundi, biragoye guca ibikoresho.

5: Ihame ryimiterere yibigize: A: Ihame rusange: Mugushushanya kwa PCB, niba hariho imiyoboro yombi ya sisitemu hamwe nizunguruka zisa muri sisitemu yumuzunguruko. Nka-Inzira-Yumuzunguruko, igomba gushyirwaho ukwayo kugirango igabanye guhuza sisitemu. Mu bwoko bumwe bwumuzunguruko, ibice bishyirwa mubice no kugabana ukurikije icyerekezo cyerekana ibimenyetso n'imikorere.

6: Iyinjiza ryibikoresho bitunganyirizwa, ibyasohotse byerekana ibimenyetso bigomba kuba hafi yumurongo wumuzunguruko, gukora ibyinjira nibisohoka umurongo mugihe gito gishoboka, kugirango ugabanye kwivanga kwinjizwa nibisohoka.

7: Icyerekezo cyo gushyira ibice: Ibigize bishobora gutondekwa gusa mubyerekezo bibiri, bitambitse kandi bihagaritse. Bitabaye ibyo, gucomeka ntibyemewe.

8: Umwanya uri hagati. Ku mbaho ​​ziciriritse ziciriritse, intera iri hagati yutuntu duto nka résistants nkeya, capacator, diode, nibindi bikoresho byihariye bifitanye isano no gucomeka no gusudira. Mugihe cyo kugurisha umuraba, umwanya wibigize urashobora kuba 50-100MIL (1.27-2.54MM). Kinini, nko gufata 100MIL, chip yumuzingi ihuriweho, intera yibigize muri rusange 100-150MIL.

9: Iyo itandukaniro rishobora kuba hagati yibigize ari rinini, intera iri hagati yibigize igomba kuba nini bihagije kugirango wirinde gusohoka.

10: Muri IC, capacitor ya decoupling igomba kuba hafi yumuriro wamashanyarazi pin. Bitabaye ibyo, gushungura ingaruka bizaba bibi. Mumuzunguruko wa digitale, kugirango hamenyekane imikorere yizewe ya sisitemu yumuzunguruko, ubushobozi bwa IC decoupling capacator zishyirwa hagati yumuriro nubutaka bwa buri chip chip yumuzingi. Kurangiza ubushobozi bwa capacitori ikoresha ceramic chip capacator ifite ubushobozi bwa 0.01 ~ 0.1 UF. Guhitamo ubushobozi bwa decoupling capacitor muri rusange bishingiye ku gusubiranamo kwa sisitemu ikora inshuro F. Byongeye kandi, capacitor ya 10UF hamwe na 0.01 UF ceramic capacitor nayo irasabwa hagati yumurongo wamashanyarazi nubutaka ku bwinjiriro bwumuriro w'amashanyarazi.

11. Kandi nibyiza kudakoresha insinga hepfo.
