Makulidwe ndi Zinthu
Mapulogalamu
Telefoni, Mawotchi, Zida zachipatala, Zinthu zapa digito, Zoseweretsa, Zipangizo zovomerezeka, Makompyuta a Note, Mavuni a Microwave, Zowongolera mpweya, Zamagetsi zakunyumba, Zipangizo zowongolera zokha.
Kusamalira Chidziwitso
1. Chonde musakhudze chigawocho ndi dzanja lopanda kanthu, chifukwa electrode mwina corrode.
2. Pewani kukoka mochulukira kwa waya wotsogolera chifukwa waya akhoza kuthyoka kapena nsonga yodulira imatha kutsika.
3. Mabwalowa amagwiritsa ntchito kusintha kwa transistor, Magawo ozungulira a heft a transistor amasankhidwa bwino kuti akhale okhazikika, ndiye chonde tsatirani mukapanga dera.
4. Zowulira maginito zimayendetsedwa ndi ma frequency olowera, mawonekedwe omwe amaperekedwa amatha kupezeka pokhapokha mutagwiritsa ntchito 1/2 duty square wave(Vb-p).Ogwiritsa ntchito kumapeto ayenera kudziwa zowona kuti mawonekedwe amafupipafupi amatha kusintha mawonekedwe osiyanasiyana ndi mafunde osiyanasiyana, monga sine wave, square wave (Vb-p) kapena mafunde ena.
5. Pamene magetsi ena agwiritsidwa ntchito kuposa momwe akulimbikitsira, zizindikiro zafupipafupi zidzasinthidwanso.
6. Chonde sungani mtunda woyenera wa mphamvu ya maginito pamene mukusunga, podutsa ndi kukwera.
Soldering Ndi Kukwera
1. Chonde werengani za HYDZ specifications, ngati soldering chigawo chofunika.
2. Kutsuka kwa chigawocho sikuloledwa, chifukwa sikumayesedwa.
3. Chonde musatseke dzenjelo ndi tepi kapena zopinga zina, chifukwa izi zidzatulutsa ntchito yosasinthika.
