Hariho amategeko menshi ya PCB. Ibikurikira nurugero rwo gutunganya amashanyarazi. Igenamiterere ry'amashanyarazi ninama y'umuzunguruko mu mbaraga zigomba kubahiriza amategeko, harimo intera y'umutekano, igenamigambi rigufi, igenamigambi rigufi. Igenamiterere ryibi bipimo bizagira ingaruka kubiciro byatanga umusaruro, gushushanya ingorane nigikorwa cyukuri muri PCB yashizweho, kandi igomba gufatwa neza.
1.Gutegeka amategeko
Igishushanyo cya PCB gifite umuyoboro umwe, umuyoboro utandukanye wumuyoboro, ubundi, ubugari bwumurongo ukeneye kuri 6mil, ubugari bwintangarugero) busanzwe (ntarengwa igizwe na 200mil. Igenamiterere ryihariye ukurikije ingorane zubuyobozi bwinama.
Umurongo washyizweho na Spacip nawo ugomba kumvikana nuwabikoze mbere, kuko abakora bamwe ntibashobora kugera ku murongo washyizweho no kunyura mu kibazo cyo gutunganya, kandi gito cyane ku murongo w'ubushobozi bwo gutunganya no kumena.
2. Hagati ya Gracing 3w
Byose byashizweho kumurongo wisaha, umurongo utandukanye, videwo, amajwi, gusubiramo umurongo nindi mirongo ikomeye ya sisitemu. Iyo insinga nyinshi zo hejuru yihuta zigenda intera ndende, kugirango ugabanye ibiganiro hagati yumurongo, umurongo wa stacung ugomba kuba munini bihagije. Iyo umurongo wikigo kitari munsi yinshuro 3 umurongo, imirima myinshi ntishobora kubangamirana, niyihe itegeko rya 3w. Itegeko rya 3w rituma 70% yimirima ibangamirana, hamwe na 10w, 98% yimirima irashobora kugerwaho atabangamiye.
3.20H Itegeko Kuri Imbaraga
Itegeko rya 20h ryerekeza ku ntera 20h iri hagati yububiko bwimbaraga nuburyo bwo gushiraho, birumvikana ko kubuza ingaruka zimyanda. Kuberako amashanyarazi hagati yubutaka nubutaka arahinduka, intervagnetic kwivanga bizamura hanze yisahani, yitwa ingaruka. Igisubizo nugugabanya urwego rwingufu kugirango urumuri rwamashanyarazi rwashyire gusa murwego rwubutaka. Hamwe na H (umubyimba wo hagati hagati yinyamanswa nubutaka) mugihe igice, 70% yumurima wamashanyarazi bishobora kugarukira ku nkombe yubutaka hamwe no kugabanuka kwa 100h.
4.kusanya kumurongo wa impetance
Imiterere igoye yo kugenzura ihuza igizwe n'imirongo ibiri itandukanye. Ibimenyetso byinjiza kumushoferi birangiye ni hejuru y'ibimenyetso bibiri bya posita ya polarity, yakondutse imirongo ibiri itandukanye, hamwe nibimenyetso bibiri bitandukanye kumutwe wakira biravanwaho. Ubu buryo bukoreshwa cyane cyane mumuzunguruko wihuta ya digitale ya analog kugirango ubunyangamugayo bwiza bugaragaze ibimenyetso byurusaku. Impetance ninganiye kuri itandukaniro umurongo intera, kandi itandukaniro rinini umurongo unyura, niko intera.
Itera intera ya 5.
Intera y'amashanyarazi na creepage intera ni ngombwa mu buryo bwa PCB igishushanyo mbonera cya voltage yahinduye amashanyarazi. Niba amashanyarazi agabarika hamwe nintoki ni nto cyane, birakenewe kwitondera imiterere yatemye. Creepage Spacing hamwe namashanyarazi mugihe cya PCB, icyuho cyamashanyarazi kirashobora guhinduka muburyo bwo guhindura umwanya uva kuri padi kuri padi. Iyo PCB Umwanya wa PCB ugurumana, uduce twa creepage rushobora kwiyongera kubiryoshye.
