Mu nganda za elegitoroniki, imbaho ​​nyinshi za PCB zumuzunguruko zahindutse igice cyibanze cyibikoresho byinshi bya elegitoroniki yo mu rwego rwo hejuru hamwe n’ibikoresho byahujwe cyane kandi bigoye. Nyamara, imiterere-yuburyo bwinshi nayo izana urukurikirane rwo kugerageza no gusesengura ibibazo.

1. Ibiranga ibice byinshi bya PCB byumuzunguruko
Ibice byinshi byumuzunguruko wa PCB mubisanzwe bigizwe nibice byinshi bisimburana byayobora kandi bikingira, kandi imiterere yabyo iragoye kandi yuzuye. Iyi miterere-yuburyo bwinshi ifite ibintu byingenzi bikurikira:

Kwishyira hamwe kwinshi: Bashoboye guhuza umubare munini wibikoresho bya elegitoronike hamwe nizunguruka mumwanya muto kugirango uhuze ibikenerwa nibikoresho bya elegitoroniki bigezweho kugirango miniaturizasi ikore neza.
Ihererekanyabubasha rihamye: Binyuze mu gishushanyo mbonera cyiza, guhuza ibimenyetso n’urusaku birashobora kugabanuka, kandi ubwiza n’umutekano byo kohereza ibimenyetso birashobora kunozwa.
Imikorere myiza yo gukwirakwiza ubushyuhe: Imiterere-yuburyo bwinshi irashobora gukwirakwiza neza ubushyuhe, kugabanya ubushyuhe bwimikorere yibikoresho bya elegitoroniki, no kuzamura ubwizerwe nubuzima bwibikoresho.

2. Akamaro ko kugerageza ibyiciro byinshi byo kugerageza ibice byinshi byumuzunguruko wa PCB
Menya neza ibicuruzwa byiza: Mugerageze imiterere-yuburyo bwinshi bwibibaho byumuzunguruko wa PCB, ibibazo bishobora kuba byiza, nkumuzunguruko mugufi, imiyoboro ifunguye, imiyoboro mibi ihuza imiyoboro, nibindi, bishobora kuvumburwa mugihe, bityo bigatuma ibicuruzwa byujuje ubuziranenge. no kwizerwa.
Igisubizo cyiza cyo gukemura: Ibisubizo byikizamini birashobora gutanga ibitekerezo kubishushanyo mbonera byumuzunguruko, bifasha abashushanya guhuza imiterere ya wiring, guhitamo ibikoresho nibikorwa, no kunoza imikorere yumuzunguruko no gukora.
Kugabanya ibiciro byumusaruro: Kwipimisha neza mugihe cyumusaruro birashobora kugabanya igipimo cyakuweho numubare wibikorwa, kugabanya ibiciro byumusaruro, no kuzamura umusaruro.

3. Inzira nyinshi PCB izunguruka ikibaho cyuburyo bwinshi bwo kugerageza imiterere
Ikizamini cyo gukora amashanyarazi
Ikizamini cyo gukomeza: Reba ubudahwema hagati yimirongo itandukanye kurubaho rwumuzunguruko kugirango urebe ko ntamuzingo mugufi cyangwa imiyoboro ifunguye. Urashobora gukoresha multimetero, ibizamini bikomeza nibindi bikoresho byo kwipimisha.
Ikizamini cyo kurwanya insulasiyo: Gupima ubukana bwokwirinda hagati yuburyo butandukanye ku kibaho cyumuzunguruko no hagati yumurongo nubutaka kugirango umenye niba imikorere yimikorere ari nziza. Mubisanzwe byageragejwe ukoresheje ibizamini byo kurwanya insulation.
Ikizamini cy'ubunyangamugayo bw'ikimenyetso: Mugupima ibimenyetso byihuta byihuta kumuzunguruko, gusesengura ubwiza bwikwirakwizwa, kugaragariza, kunyura hamwe nibindi bipimo byerekana ibimenyetso kugirango uburinganire bwikimenyetso. Ibikoresho nka oscilloscopes hamwe nisesengura ryibimenyetso birashobora gukoreshwa mugupima.

Ikizamini cyimiterere yumubiri
Gupima uburebure bwa interineti: Koresha ibikoresho nkigikoresho cyo gupima ubunini kugirango upime ubunini buri hagati yikibaho cyumuzingi wa PCB cyumuzingi kugirango urebe ko cyujuje ibisabwa.
Ibipimo bya diameter ya Hole: Reba umurambararo wa diametre hamwe nukuri neza kumwanya wumuzunguruko kugirango umenye neza kandi uhuze ibikoresho bya elegitoroniki. Ibi birashobora kugeragezwa ukoresheje boremeter.
Ikizamini cyo hejuru yubuso: Koresha ibikoresho bipima uburinganire nibindi bikoresho kugirango umenye uburinganire bwikibaho cyumuzunguruko kugirango wirinde ubuso butaringaniye kugira ingaruka ku gusudira no kwishyiriraho ibikoresho bya elegitoroniki.

Ikizamini cyo kwizerwa
Ikizamini cya Thermal shock: Ikibaho cyumuzunguruko gishyirwa mubushyuhe bwo hejuru kandi buke kandi bigahinduka ukundi, kandi imikorere yayo mugihe cyimihindagurikire yubushyuhe iraboneka kugirango isuzume ubwizerwe nubushyuhe bwayo.
Ikizamini cyo kunyeganyega: Kora ikizamini cyo kunyeganyega ku kibaho cyumuzunguruko kugirango wigane imiterere yinyeganyeza mu mikoreshereze nyayo kandi urebe niba ihuza ryayo ryizewe hamwe n’imikorere ihagaze neza mu gihe cyo kunyeganyega.
Ikizamini gishyushye: Shyira ikibaho cyumuzunguruko ahantu h’ubushyuhe n'ubushyuhe bwo hejuru kugirango ugerageze imikorere yacyo kandi irwanya ruswa ahantu hashyushye.

4. Isesengura ryibice byinshi bya PCB byumuzunguruko
Isesengura ry'ubunyangamugayo
Mugusesengura ibisubizo byubuziranenge bwibimenyetso, dushobora gusobanukirwa kohereza ibimenyetso kumurongo wumuzunguruko, kumenya intandaro yo kwerekana ibimenyetso, kwambukiranya ibindi bibazo, no gufata ingamba zijyanye no gutezimbere. Kurugero, urashobora guhindura imiterere ya wiring, ukongera imbaraga zo guhagarika, gukoresha ingamba zo gukingira, nibindi kugirango uzamure ubwiza nibihamye byikimenyetso.
isesengura ry'ubushyuhe
Ukoresheje porogaramu yo gusesengura ubushyuhe kugirango usesengure imikorere yo gukwirakwiza ubushyuhe bwibice byinshi byumuzunguruko wa PCB, urashobora kumenya ikwirakwizwa ryibibanza bishyushye ku kibaho cy’umuzunguruko, ugahindura igishushanyo mbonera cy’ubushyuhe, kandi ukazamura ubwizerwe nubuzima bwubuyobozi bwumuzunguruko. Kurugero, urashobora kongeramo ubushyuhe, guhindura imiterere yibikoresho bya elegitoronike, hitamo ibikoresho bifite imiterere myiza yo gukwirakwiza ubushyuhe, nibindi.
isesengura ryizewe
Hashingiwe ku bisubizo by’ibizamini byizewe, hasuzumwa ubwizerwe bwibice byinshi byumuzunguruko wa PCB byumuzunguruko, uburyo bwo gutsindwa hamwe nuburyo budahwitse buramenyekana, hanafatwa ingamba zihamye zo kunoza. Kurugero, igishushanyo mbonera cyibibaho byumuzunguruko birashobora gushimangirwa, ubwiza no kwangirika kw ibikoresho bishobora kunozwa, kandi umusaruro urashobora kuba mwiza.

Igeragezwa ryimiterere myinshi nisesengura ryibice byinshi byumuzunguruko wa PCB nintambwe yingenzi muguharanira ubwiza nubwizerwe bwibikoresho bya elegitoroniki. Ukoresheje uburyo bwiza bwo gupima nuburyo bwo gusesengura, ibibazo bivuka mugihe cyo gushushanya, gukora no gukoresha imbaho ​​zumuzunguruko birashobora kuvumburwa no gukemurwa mugihe gikwiye, kunoza imikorere nogukora imbaho ​​zumuzunguruko, kugabanya ibiciro byumusaruro, no gutanga inkunga ikomeye kuri iterambere ryinganda za elegitoroniki. inkunga.
