Iindlela zokufumana ibhodi yePCB eneziphene

  1. Ngokulinganisa iVoltage

 

Into yokuqala yokuqinisekisa kukuba ingaba i-voltage yephini nganye yamandla etshiphu iqhelekile okanye hayi, emva koko khangela ukuba i-voltage eyahlukeneyo yereferensi iqhelekile okanye hayi, ukongeza kwindawo yombane osebenzayo. Ngokomzekelo, i-silicon triode eqhelekileyo ine-BE junction voltage malunga ne-0.7V, kunye ne-CE junction voltage malunga ne-0.3V okanye ngaphantsi. darlington ityhubhu, njl.njl.), isiphambuka se-BE sinokuvuleka.

2.inaliti yomqondiso

Iza kubonakalisa igalelo, kwaye emva koko ilinganise i-waveform kwindawo nganye, jonga ukuba iqhelekile na, ukufumana indawo yempazamo ngamanye amaxesha sisebenzisa indlela elula, kunye ne-forceps esandleni, umzekelo, ukubamba kuwo onke amanqanaba igalelo, isiphumo sempendulo yecala, isekethe eyandisiweyo efana nevidiyo yeaudio ihlala isetyenziswa (kodwa qaphela ukuba ipleyiti eshushu okanye isekethe yombane ophezulu, ayinakusebenzisa le ndlela, kungenjalo inokukhokelela kumothuko wombane) ukuba ubambe phambi kwenqanaba phendula, kwaye uthinte emva kwenqanaba le-1, ke ingxaki kwinqanaba lokuqala, kufuneka ligxininise ekuhloleni

Ezinye iindlela zokufumana iPCB eneziphene

Zininzi ezinye iindlela zokukhangela iindawo ezinengxaki, njengokubona, ukuva, ukujoja, ukubamba, njl.

1”Ukubona” kuthetha ukubona ukuba icandelo linomonakalo ocacileyo womatshini, njengokugqabhuka, ukwenza mnyama, ukujika, njl.;
2.”Mamela” kukumamela ukuba ingaba isandi somsebenzi siqhelekile na, njengokuba abanye mabangavakali izinto eringini, isandi saloo ndawo asivakali okanye asivakali esingaqhelekanga, njl. njl.;

3 "Ukunuka" kukukhangela ivumba, elifana nevumba elivuthayo, ivumba le-capacitor electrolyte, njl. njl., kubasebenzi abanamava okulungisa umbane, obuthathaka kakhulu kula mavumba;
4.Uku “bamba” kuthetha ukuvavanya ubushushu besixhobo ngesandla ukubona ukuba buqhelekile na, njengokutshisa kakhulu okanye ukubanda kakhulu.
Ezinye izixhobo zamandla, ukuba ziya kuba shushu xa zisebenza, ukuba umntu ubamba ukubanda, kunokugwetywa ngokusisiseko ukuba ayisebenzi. Kodwa ukuba kushushu kakhulu apho kungafanelekanga okanye kushushu kakhulu apho kufanele ukuba kube khona, oko akuyi kusebenza. I-transistor yamandla ngokubanzi, i-chip ye-voltage regulator, njl., ukusebenza kwii-70 degrees ngezantsi akukho ngxaki ngokupheleleyo. Ingaba i-70 degrees ijongeka njani? Ukuba ucinezela isandla sakho kuyo, ungayibamba ngaphezu kwemizuzwana emithathu, oku kuthetha ukuba ubushushu bungaphantsi kwama-70 degrees.
