Kugenzura no gusana PCB

1. Gukata hamwe na porogaramu
1. Chip ya EPROM mubusanzwe ntabwo ikwiriye kwangirika.Kuberako ubu bwoko bwa chip bukenera urumuri ultraviolet kugirango uhanagure gahunda, ntabwo byangiza gahunda mugihe cyizamini.Nyamara, hari amakuru: bitewe nibikoresho byakoreshejwe mugukora chip, uko ibihe bigenda bisimburana), nubwo bidakoreshwa, birashobora kwangirika (cyane cyane bivuga gahunda).Birakenewe rero kubishyigikira hejuru bishoboka.
2. EEPROM, SPROM, nibindi, kimwe na RAM chip hamwe na bateri, biroroshye cyane gusenya gahunda.Niba izo chip zizasenya gahunda nyuma yo gukoreshagusikana umurongo wa VI nturarangira.Ariko, abo dukorana Iyo duhuye nibibazo nkibi, nibyiza kwitonda.Umwanditsi yakoze ubushakashatsi bwinshi, kandi impamvu ishoboka cyane ni: kumeneka kw'igikonoshwa cy'ibikoresho byo kubungabunga (nka tester, ibyuma byo kugurisha amashanyarazi, n'ibindi).
3. Kuri chip ifite bateri ku kibaho cyumuzunguruko, ntukayikure ku kibaho byoroshye.

2. Kugarura uruziga
1. Iyo hari uruziga runini rwuzuzanya ku kibaho cyumuzunguruko rugomba gusanwa, hagomba kwitonderwa ikibazo cyo gusubiramo.
2. Mbere yikizamini, nibyiza kuyisubiza mugikoresho, kuzimya no kuzimya imashini inshuro nyinshi hanyuma ukagerageza.Kandi kanda buto yo gusubiramo inshuro nyinshi.

3. Ikizamini cyimikorere nibipimo
1.irashobora kwerekana gusa agace kaciwe, agace kongererwa hamwe nu gice cyuzuye mugihe cyo kumenya igikoresho.Ariko ntishobora gupima indangagaciro zihariye nkinshuro zikorwa n'umuvuduko.
2. Muri ubwo buryo, kuri TTL chip ya digitale, gusa ibisohoka bihinduka murwego rwo hejuru kandi ruto birashobora kumenyekana, ariko umuvuduko wizamuka no kugwa kumpande ntushobora kuboneka.

4. Oscillator ya Crystal
1. Mubisanzwe gusa oscilloscope (oscillator ya kristu ikenera gukoreshwa) cyangwa metero yumurongo irashobora gukoreshwa mugupima, kandi multimeter ntishobora gukoreshwa mugupima, naho ubundi uburyo bwo gusimbuza bushobora gukoreshwa gusa.
2. Amakosa asanzwe ya oscillator ya kristu ni: a.kumeneka imbere, b.imbere imbere, c.Guhindagurika inshuro nyinshi, d.kumeneka kwa peripheri ihujwe.Ikintu cyo kumeneka hano kigomba gupimwa na VI umurongo wa.
3. Uburyo bubiri bwo guca imanza burashobora gukoreshwa mubizamini byose byubuyobozi: a.Mugihe cyikizamini, ibyuma bifitanye isano hafi ya kristu oscillator birananirana.b.Ntayindi ngingo yibeshya iboneka usibye kristu oscillator.

4. Hariho ubwoko bubiri busanzwe bwa kristu ihindagurika: a.amapine abiri.b.amapine ane, muriyo pin ya kabiri ikoreshwa, kandi kwitabwaho ntibigomba kuba bigufi-bizunguruka uko bishakiye.Bitanu.Ikwirakwizwa ryibyabaye 1. Imibare ituzuye yibice byikibaho cyumuzunguruko: 1) chip yangiritse 30%, 2) ibice byangiritse byangiza 30%,
3) 30% by'insinga (P.CB umuringa usize umuringa) wacitse, 4) 10% ya porogaramu yangiritse cyangwa yatakaye (hari inzira yo kuzamuka).
2. Birashobora kugaragara uhereye hejuru ko mugihe hari ikibazo kijyanye no guhuza na gahunda yinama yumuzunguruko igomba gusanwa, kandi nta kibaho cyiza, kitamenyereye isano ryacyo, kandi ntigishobora kubona gahunda yumwimerere, ibishoboka yo gusana ikibaho ntabwo ari kinini.
