Hano hari amategeko menshi yo gushushanya PCB.Ibikurikira nurugero rwumutekano wumuriro.Igenamigambi ryamashanyarazi nigishushanyo mbonera cyumuzunguruko mu nsinga kigomba kubahiriza amategeko, harimo intera yumutekano, imiyoboro ifunguye, imiyoboro ngufi.Igenamiterere ryibi bipimo bizagira ingaruka kubikorwa byumusaruro, ingorane zo gushushanya no gushushanya neza kwa PCB yateguwe, kandi bigomba gufatwa neza.

1.Amategeko asobanutse

Igishushanyo cya PCB gifite intera imwe, intera itandukanye yumutekano wumutekano, ibindi, ubugari bwumurongo bigomba gushyirwaho, ubugari bwumurongo wambere hamwe nintera ni 6mil, intera isanzwe ni 6mil, ubugari bwumurongo ntarengwa bwashyizwe kuri 6mil, agaciro kasabwe ( ubugari bwa wiring isanzwe) yashyizwe kuri 10mil, ntarengwa yashyizwe kuri 200mil.Igenamiterere ryihariye ukurikije ingorane zo gushiraho insinga.

Ubugari bwumurongo washyizweho nuburinganire nabyo bigomba kumvikana nuwabikoze PCB hakiri kare, kubera ko ababikora bamwe badashobora kugera kumurongo wubugari bwumurongo no gutandukanya bitewe nikibazo cyubushobozi bwibikorwa, kandi ntoya umurongo ubugari n'umwanya, ikiguzi kiri hejuru.

2.Itegeko ryumurongo wa 3W

Byose byateguwe kumurongo wamasaha, umurongo utandukanye, videwo, amajwi, gusubiramo umurongo nindi sisitemu ikomeye.Iyo insinga nyinshi zihuta cyane zerekana insinga ndende, kugirango ugabanye ibiganiro hagati yumurongo, intera yumurongo igomba kuba nini bihagije.Iyo umurongo uri hagati yumurongo utari munsi yinshuro 3 z'ubugari bwumurongo, imirima myinshi yamashanyarazi ntishobora kubangamirana, ariryo tegeko rya 3W.Amategeko ya 3W atuma 70% yimirima itabangamirana, kandi hamwe nu mwanya wa 10W, imirima 98% irashobora kugerwaho utabangamiye undi.

3.20H amategeko agenga ingufu

Amategeko ya 20H yerekeza ku ntera ya 20H hagati yumuriro wamashanyarazi no gushingwa, birumvikana ko kubuza ingaruka zumuriro.Kuberako umurima wamashanyarazi hagati yububasha bwubutaka nubutaka burahinduka, interineti ya electronique irasa hanze kumpera yisahani, ibyo bita inkurikizi.Igisubizo nukugabanya ingufu zitanga amashanyarazi kuburyo umurima wamashanyarazi woherezwa gusa mubutaka bwubutaka.Hamwe na H (ubunini bwikigereranyo hagati yinkomoko yubutaka nubutaka) nkigice, 70% byumurima wamashanyarazi urashobora kugarukira kumpera yubutaka hamwe no kugabanuka kwa 20H, na 98% byumuriro wamashanyarazi urashobora gufungirwa no kugabanuka kwa 100H.

4.Inkurikizi z'umurongo utambamirwa

Imiterere igoye yo kugenzura inzitizi igizwe n'imirongo ibiri itandukanye.Ibimenyetso byinjiza kumurongo wumushoferi nibimenyetso bibiri byerekana imirongo itandukanye ya polarite, ikoherezwa kumirongo ibiri itandukanye, kandi ibimenyetso bibiri bitandukanye kumurongo wakira byakuweho.Ubu buryo bukoreshwa cyane cyane muburyo bwihuse bwa digitale ya analog kugirango ibe inyangamugayo nziza kandi irwanya urusaku.Impedance iringaniza itandukanyirizo ryumurongo, kandi uko intera itandukanijwe, niko impedance nini.

5. Intera y'amashanyarazi

Gukuraho amashanyarazi hamwe nintera yikurikiranya nibyingenzi muburyo bwa PCB mugushushanya amashanyarazi menshi.Niba amashanyarazi hamwe nintera yikurikiranya ari nto cyane, birakenewe ko twita kumiterere yamenetse.Umwanya wa creepage hamwe nu cyuho cyamashanyarazi Mugihe cyashushanyaga PCB, icyuho cyamashanyarazi kirashobora guhindurwa nuburyo bugamije guhindura intera kuva kuri padi kugeza kuri padi.Iyo umwanya wa PCB ufunganye, umwanya wa creepage urashobora kwiyongera mugusunika.
