Icyerekezo cyikizamini muri PCB numuringa wagaragaye ushobora gukoreshwa kugirango ugenzure niba umuzenguruko ukora kugirango asobanure. Mugihe cyo gutanga umusaruro, abakoresha barashobora gutesha agaciro ibimenyetso byipimisha binyuze mubigeragezo kugirango babone ibibazo bishobora. Ikizamini cyibizamini bigena niba ikimenyetso cyatanzwe ari gito / hejuru ugereranije nibisubizo byifuzwa hamwe nimpinduka nziza zirashobora gutangizwa kugirango ubigereho.

ThePCB Ikizaminiigomba kuba iri ku kibaho cyo hanze. Ibi bituma ibikoresho byikizamini bigera kugirango bahure nayo hanyuma ukore ikizamini. Inama zipimisha iboneka muburyo butandukanye bwo kwipimisha ibintu bitandukanye (Flat, Ibice, Ibitekerezo, nibindi) bituma buri cyerekeza kuri buri kizamini kijyanye nicyemezo gikwiye. Ibi bituma abashushanya bagena amakaramu ariho kandi vias ku kibaho nkicyerekezo cyikizamini.

Ubwoko bw'ibizamini

Ikizamini cya Probe

Ubwoko bwa mbere bwikizamini ni ingingo yoroshye ishobora kuboneka numutekinisiye ukoresheje igikoresho cyamaboko cyangwa ikipe. Ibizamini byikizamini birashobora kumenyekana byoroshye nka "GND", "Pwr" nibindi. Ikizamini cya Probe gikorwa kugirango ukore urwego rwo hejuru

Ibizamini byikora

Ubwoko bwa kabiri bwikizamini bukoreshwa mubikoresho byikora byikora. Ingingo z'ibizamini byikora kuri PCB ni Vias, Amapaki ya Thru-Hole, hamwe na padi ntoya yicyuma cyagenewe kwakira ibibazo bya sisitemu yikizamini cyikora. Ibizamini byikora bituma inzira zipimisha zikoresha imyitozo ikizamini cyikora. Bafite ubwoko butatu:

1. Ikizamini cyambaye ubusa: Kwipimisha inama yambaye ubusa bikorwa mbere yo guterana kw'ibice kugirango tumenye ko hari imiyoboro myiza y'amashanyarazi mu butegetsi.

2. Kwipimisha mukarere (ICT):Ikizamini cya ICT gikozwe kugirango ibice byose bigize kubuyobozi burimo gukora nkuko bikwiye. Ibikorwa bivuye mubizamini bizahura nibizamini byikizamini kumuzunguruko kugirango ukore ikizamini.

3. Kuguruka kwipimisha Probe (FPT):Kwipimisha Probe (FPT) nikizamini cyikora cyakoreshejwe mugusuzuma imikorere myiza yibigize ku kibaho cya PCB. Muri iki kizamini, ibishoboka byinshi cyangwa byinshi byateguwe kugirango uzunguruke mu kirere no kubona ibice bitandukanye bipimisha, bigufi, indangagaciro, indangagaciro, hamwe nicyerekezo cyibice.

Ibintu ugomba gusuzuma mugihe ushyira mubikorwa ikizamini kuri PCB:

Ikwirakwizwa ryigihe cyikizamini: Ingingo z'ikizamini zigomba gutangwa neza muri PCB kugirango ibizamini byinshi bishoboke icyarimwe.
Kuruhande rwumuyobozi: Ingingo z'ikizamini zigomba gushyirwa kuruhande rumwe rwa PCB ifasha mugukiza igihe namafaranga.
Intera miriminal test intera: Ingingo z'ikizamini zigomba kugira intera ntoya ya santimetero 0.100 hagati yabo kugirango utezimbere ingirakamaro,

Ibyiza byo kongeramo amanota kuri PCB:

Gutahura ikosa ryoroshye
● Igihe no kuzigama
Biroroshye gushyira mu bikorwa

Ingingo z'ikizamini ni ngombwa mugukemura ubusugire bwa PCB. Umubare w'ibizamini ku kibaho cya PCB kigomba kugarukira kuko ari agace k'umuringa wagaragaye bishobora ku bw'impanuka ku buryo bugufi ku kindi cyerekezo cya hafi no kwangiza umuzenguruko.
