Abu na farko da za a tabbatar da shi shi ne ko wutar lantarki ta kowane fil ɗin wutar lantarki ta al'ada ce ko a'a, sannan duba ko nau'in wutar lantarki iri-iri na al'ada ne ko a'a, ban da ma'anar wutar lantarki mai aiki. Misali, nau'in siliki na al'ada yana da ƙarfin junction na BE kusan 0.7V, da ƙarfin junction CE na kusan 0.3V ko ƙasa da haka.Idan ƙarfin junction na BE na transistor ya fi 0.7V (sai dai transistor na musamman, kamar su). tube darlington, da sauransu), mahadar BE na iya buɗewa.

Za a yi sigina don shigar da shi, sannan a bi da bi don auna yanayin motsi a kowane wuri, duba ko na al'ada, don nemo maƙasudin kuskure a wasu lokuta muna amfani da hanya mafi sauƙi, tare da ƙarfi a hannu, misali, don taɓa kowane matakan. shigarwar, da fitarwa gefen dauki, da amplifying da'ira kamar audio video sau da yawa amfani (amma lura cewa zafi farantin ko high ƙarfin lantarki kewaye, ba zai iya amfani da wannan hanya, in ba haka ba zai iya haifar da lantarki girgiza) idan taba kafin matakin kar a. amsa, kuma ku taɓa bayan matakin 1, to matsalar a matakin farko, yakamata a mai da hankali kan dubawa
Wasu hanyoyin don nemo PCB maras kyau
Akwai wasu hanyoyi da yawa don neman wuraren da za a sami matsala, kamar gani, ji, wari, taɓawa, da sauransu.
1. "Don gani" yana nufin ganin ko sashin yana da lalacewa na inji, kamar fashewa, baƙar fata, nakasawa, da dai sauransu;
2.”Saurara” shine a saurari ko sautin aikin ya kasance na al'ada, kamar wasu bai kamata su yi sauti a cikin zobe ba, sautin wurin ba ya da kyau ko mara kyau, da sauransu;
3.” Kamshi” shi ne a duba ko wane irin wari, kamar kona warin, warin capacitor electrolyte, da sauransu, ga gogaggen ma’aikacin kula da wutar lantarki, wanda ke da kamshi sosai;
4.Don “taɓawa” yana nufin gwada zafin na'urar da hannu don ganin ko al'ada ce, kamar zafi ko sanyi sosai.
Wasu na'urorin wuta, idan za su yi zafi lokacin aiki, idan mutum ya taɓa mai sanyi, ana iya yanke hukunci cewa ba ya aiki. Amma idan ya yi zafi sosai a inda bai kamata ba ko kuma inda ya kamata ya yi zafi, hakan ba zai yi tasiri ba. Babban transistor wutar lantarki, guntu mai sarrafa wutar lantarki, da sauransu, aiki a digiri 70 a ƙasa gaba ɗaya ba matsala. Me yayi kama da digiri 70? Idan ka danna hannunka akan sa, zaka iya rike shi fiye da dakika uku, wanda ke nufin yanayin zafi ya kasa digiri 70.
