Ihame ryo gupima PCBA

Ukoresheje ingaruka zingutu zicyuma, gage ya gage yometse kuri PCBA irashobora kugereranywa nimpinduka zagaciro kayo yo kurwanya iyo PCBA ihindutse igahinduka imashini.Umubare wuzuye urashobora kugereranwa numurongo wanyuma kugirango umenye ibyago byo guhinduka kwa PCBA kubice cyangwa amabati yaturika yibigize.Tanga icyerekezo cyingamba zo kunoza imikorere ya PCBA.

Sisitemu yo kwipimisha itahura impinduka ya voltage iterwa nihinduka ryimiterere ya gauge irwanya ikiraro cya Wheatstone, hanyuma igahindura impinduka ya voltage mumashanyarazi binyuze muri porogaramu muri software igerageza.

Ururabyo rwamashanyarazi ni igipimo kirimo ibice bitatu byigenga byigenga, byegeranye kuri buri mwanya kugirango bapime umurongo ku mashoka yabo ahantu hamwe.
Imyitozo isobanurwa nk (ihinduka ryuburebure) / (uburebure bwumwimerere), nubunini bwumubiri butagira urugero, mubizamini bya PCBA, kubera ko agaciro koroheje ari gake cyane, ubusanzwe gasobanurwa na microstrain (με), ukurikije 106 * (guhindura uburebure) / (uburebure bwumwimerere) kugirango asobanure microstrain.

Mu kizamini cya PCBA, ikibazo cya PCBA nikibazo cyindege.Sisitemu yo gusesengura ibizamini irashobora kubara igipimo nyamukuru nigipimo cyibikorwa muri PCBA mugupima agaciro nyako-nyaburanga mu byerekezo bitatu byururabyo rutoshye, kugirango hamenyekane niba ibicuruzwa biva mubikorwa birenze ibipimo.

Intambwe zirenze imipaka ntarengwa zifatwa nkizikabije kandi zamenyekanye kubikorwa byo gukosora.Imipaka ntarengwa irashobora gukomoka kubakiriya, abatanga ibikoresho, cyangwa ibikorwa bizwi mubucuruzi / inganda (bikomoka kuri IPC_JEDEC-9704A).

Iyo umutwaro nyamukuru ari nini kandi ntoya ya orthogonal nini mu ndege, perpendicular kuri mugenzi we kandi tangent tangent mu cyerekezo ni zeru.Mu kizamini cya PCBA, ikibazo nyamukuru kibarwa mugupima nkibipimo ngenderwaho bikomeye.Igipimo cyingutu cyerekana igipimo cyimpinduka zingutu kumwanya umwe, zikoreshwa mugupima ibyago byangiritse byibigize.
