Izindlela zokuthola ibhodi le-PCB elinesici

  1. Ngokulinganisa Amandla kagesi

 

Into yokuqala okufanele uqinisekise ukuthi i-voltage yephinikhodi ngayinye yamandla e-chip ijwayelekile noma cha, bese uhlola ukuthi i-voltage yereferensi ehlukahlukene ijwayelekile noma cha, ngaphezu kwephuzu le-voltage yokusebenza. Isibonelo, i-silicon triode evamile ine-BE junction voltage cishe engu-0.7V, kanye ne-voltage junction ye-CE engaba ngu-0.3V noma ngaphansi. darlington tube, njll.), ukuhlangana kwe-BE kungase kuvuleke.

2.umjovo wesignali

Izosayina okokufaka, bese ibuyela emuva ukukala i-waveform kuwo wonke amaphuzu, sibheke ukuthi sijwayelekile yini, ukuze sithole iphuzu lephutha ngezinye izikhathi sisebenzisa indlela elula, siphethe i-forcep esandleni, isibonelo, ukuthinta kuwo wonke amazinga okokufaka, ukusabela ohlangothini oluphumayo, isifunda esikhulisayo njengevidiyo yomsindo kuvame ukusetshenziswa (kodwa qaphela ukuthi ipuleti elishisayo noma isifunda samandla kagesi aphezulu, ayikwazi ukusebenzisa le ndlela, ngaphandle kwalokho kungase kuholele ekushaqisweni kukagesi) uma ukuthinta ngaphambi kwezinga phendula, futhi uthinte emva kwezinga 1, bese inkinga ezingeni lokuqala, kufanele igxile ekuhloleni

Ezinye izindlela zokuthola i-PCB enesici

Ziningi ezinye izindlela zokubheka izindawo ezinezinkinga, njengokubona, ukuzwa, ukuhogela, ukuthinta, njll.

1”Ukubona” kusho ukubona ukuthi ingxenye inomonakalo osobala wokusebenza, njengokugqabuka, ukufiphala, ukuwohloka, njll.;
2.”Lalela” ukulalela ukuthi umsindo womsebenzi ujwayelekile yini, njengokuthi abanye akufanele bazwakale eringini, umsindo wendawo awuzwakali noma awuzwakali ngendlela engavamile, njll.;

3 “Ukuhogela” ukuhlola iphunga, njengephunga elivuthayo, iphunga le-capacitor electrolyte, njll., kubasebenzi abanolwazi lokulungisa ugesi, elizwela kakhulu kulawa phunga;
4.Ukuthi “thinta” kusho ukuhlola izinga lokushisa lomshini ngesandla ukuze ubone ukuthi lijwayelekile yini, njengokushisa kakhulu noma kubanda kakhulu.
Amanye amadivaysi kagesi, uma ngabe ashisa lapho esebenza, uma umuntu ethinta ukuthi kubanda, kungahlulelwa ngokuyisisekelo ukuthi akusebenzi. Kodwa uma kushisa kakhulu lapho kungafanele khona noma kushisa kakhulu lapho kufanele kube khona, lokho ngeke kusebenze. I-General power transistor, i-voltage regulator chip, njll., ukusebenza ngamadigri angu-70 ngezansi akuyona neze inkinga. Ngabe ama-degree angama-70 abukeka kanjani? Uma ucindezela isandla sakho kuyo, ungayibamba imizuzwana engaphezu kwemithathu, okusho ukuthi izinga lokushisa lingaphansi kuka-70 degrees.
