Ubuyobozi bwuzuye bwa PCB bukeneye kunyura mubikorwa byinshi kuva kumurongo kugirango barangize. Iyo inzira zose zirimo, amaherezo izinjira mu igenzura. Gusa imbaho ​​yageragejwe ya PCB izakoreshwa kubicuruzwa, niyo mpamvu yakora ibikorwa byubugenzuzi bwa PCB, iyi ni ingingo abantu bose bahangayikishijwe cyane. Ubwanditsi bukurikira bwa jinhong yumuzenguruko buzakubwira ibijyanye nubumenyi bujyanye no kwipimisha inama!

1. Iyo upima voltage cyangwa gupima umugeri hamwe na oscicloscope, ntutere umuzunguruko mugufi hagati yimpande zumuzunguruko winjijwe cyangwa probe, hanyuma upime kumurongo wa periferique uhujwe na pin. Inzoka iyo ari yo yose y'uruhindi irashobora kwangiza mu buryo bworoshye; Ugomba kwitonda mugihe ugerageza gushushanya-paki cmos ihuriweho.

2. Ntabwo byemewe gukoresha icyuma cyo kugurisha kugirango ugurishe imbaraga. Menya neza ko icyumagurisha kitishyurwa. Ubutaka igikonoshwa cyicyuma. Witondere umuzunguruko. Nibyiza gukoresha icyuma cya 6-8V-voltage izunguruka.

3. Niba ukeneye kongeramo ibice byo gusimbuza igice cyangiritse, ibice bito bigomba gukoreshwa kugirango wirinde guhuza bitari ngombwa, cyane cyane imbaraga zamajwi Amplifier Yumuzingo hamwe numuzunguruko wuruziga rugomba gukemurwa neza. Ubutaka.

4. Birabujijwe rwose gupima TV, amajwi, videwo nibindi bikoresho nta kwigunga kwamashanyarazi hamwe nibikoresho hamwe nibikoresho bifite ibishishwa bifite ishingiro. Nubwo radiyo rusange ya Cassette yahinduye imbaraga, iyo uhuye nibikoresho byihariye bya TV cyangwa amajwi, cyane cyane imbaraga zamashini zakoreshejwe, ugomba kubanza kumenyana nisahani yo gutanga amashanyarazi, bigira ingaruka kumwanya muto, bitera kurushaho kwagura amakosa.

5. Mbere yo kugenzura no gusana umuzenguruko uhujwe, ugomba kubanza kumenyera imikorere yumuzunguruko winjijwe mumbere, uruhare rwa buri PIN, hamwe na voltage isanzwe ya pin, hamwe nihame risanzwe rya pin, kandi ihame risanzwe ryumuzunguruko ugizwe nibice bya peripherk. Niba ibisabwa haruguru byujujwe, gusesengura no kugenzura bizaba byoroshye cyane.

6. Ntucire urubanza ko umuzenguruko uhujwe wangiritse byoroshye. Kuberako imirongo ihuriweho cyane ihujwe nayo, iyo umuzunguruko udasanzwe, birashobora gutuma impinduka nyinshi za voltage, kandi izi mpinduka ntabwo byanze bikunze ziterwa no kwangirika kwumuzungura. Byongeye kandi, mubihe bimwe, voltage yapimwe ya buri pin itandukanye nibisanzwe mugihe indangagaciro zihuye cyangwa zisobanura byanze bikunze, ntabwo byanze bikunze, ntabwo bivuze ko umuzenguruko ari mwiza. Kuberako amakosa amwe yoroheje ntabwo azatera impinduka muri dc voltage.
