Igishushanyo gisanzwe cya PCB kitararenga 10 a, cyangwa na 5hh00. Mubisanzwe, mubisanzwe gukora akazi gahoraho kuri PCB ntabwo irenga 2 a

Uburyo 1: Imiterere kuri PCB

Kugirango umenye ubushobozi burenze PCB, tubanza gutangirana nuburyo bwa PCB. Fata pcb ebyiri pcb nkurugero. Ubu bunyabuzima bwumuzunguruko busanzwe bufite imiterere-eshatu: uruhu rwumuringa, isahani, numutungo wumuringa. Uruhu rwumuringa ninzira inyuramo ubu kandi ibimenyetso muri PCB Pass. Dukurikije ubumenyi bwa fiziki yo hagati, dushobora kumenya ko kurwanya ikintu bifitanye isano nibikoresho, byambukiranya igice, nuburebure. Kubera ko ubungubu ku ruhu rw'umuringa, uburwayi burakosorwa. Agace ka Cross-Igice kirashobora gufatwa nkubunini bwuruhu rwumuringa, nikihebyimba cy'umuringa muburyo bwo gutunganya ibicuruzwa. Mubisanzwe umurima wumuringa ugaragarira muri oz, umuringa wumuringa wa 1 oz ni 35 um, 2 oz ni 70 um, nibindi. Noneho irashobora kwemeza ko mugihe ikigezweho kigomba kunyuzwa kuri PCB, insinga igomba kuba ngufi kandi igabyibushye, kandi igicucu cyubwinshi bwa PCB, nibyiza.

Mu buhanga nyirizina, nta gipimo gikabije cy'uburebure bw'ikirere. Mubisanzwe bikoreshwa mubuhanga: Ubunini bwumuringa / ubushyuhe buzamuka / Wire Diameter, ibi bipimo bitatu byo gupima ubushobozi bwo gutwara bwa PCB.

Ubunararibonye bwa PCB ni: Kongera umubyimba wumuringa, ugura diameter, kandi utezimbere itandukaniro ryubushyuhe bwa PCB irashobora kuzamura ubushobozi bwa PCB ubu.

Niba rero nshaka gukora ikigezweho cya 100 a, nshobora guhitamo umuringa wumuringa wa 4 oz, shiraho ubugari bwa mm 15, hanyuma wongere ubushyuhe bwo kugabanya ubushyuhe bwa PCB no kunoza umutekano.

Uburyo bwa kabiri: Terminal

Usibye kwifungisha kuri PCB, ibyapa byo kwisiga nabyo birashobora gukoreshwa.

Gukosora imitwe myinshi ishobora kwihanganira 100 a kuri PCB cyangwa ibicuruzwa bikaba, pcb terminals, nibindi hanyuma ukoreshe termils nka compler yo guhuza insinga zishobora guhangana ninsinga 100. Muri ubu buryo, imigezi nini irashobora kunyura mu nsinga.

03

Uburyo butatu: Umuringa Busebar

Ndetse n'utubari b'umuringa rushobora guhindurwa. Nibikorwa bisanzwe mu nganda kugirango ukoreshe utubari b'umuringa kugirango utware imigezi nini. Kurugero, impinduka, akabati ka seriveri nibindi bikorwa bikoresha utubari b'umuringa kugirango utware imigezi nini.

04

Uburyo 4: Inzira idasanzwe

Mubyongeyeho, haribindi bintu bimwe bidasanzwe bya PCB, kandi ntushobora kubona uwabikoze mubushinwa. Infineon ifite ubwoko bwa PCB hamwe na 3-layer clayer. Ibice byo hejuru no hepfo nibisimba byifumbire, kandi urwego rwo hagati ni urwego rwumuringa ufite ubunini bwa mm 1,5, ikoreshwa ryumwihariko mugutegura imbaraga. Ubu bwoko bwa PCB burashobora kuba buto mubunini. Gutemba hejuru ya 100 A.
