Zindikirani
■ Pambuyo poti nthawi yosungira zida zatsopano zomwe zagulidwa yapitirira miyezi 6, muyenera kuyang'anitsitsa momwe zimagwiritsidwira ntchito musanagwiritse ntchito. Ndikoyenera kusunga mu phukusi la vacuum.
■ Bowolani dzenje lotentha pa PCB ndikudzaza chosungunula.
■ Kuwotcherera kobwerezabwereza ndikoyenera kwambiri powotcherera pansi, chonde onani chiyambi cha Reflow
■ Kuti zikwaniritse zofunikira za zojambulazo, radiator yokwanira iyenera kuyikidwa.
■ Onjezani kuziziritsa mpweya kapena kuziziritsa madzi ngati pakufunika.
◆ Malangizo:
■ Zochepetsera mphamvu za RF zopangidwa mwamakonda, zotsutsana ndi RF ndi ma terminal a RF zilipo.
■ Kuti mukwaniritse zofunikira za chojambulacho, ndikofunikira kukhazikitsa radiator yayikulu mokwanira. Malo achitsulo ndi ma radiator ayenera kupakidwa mafuta ofunda pang'ono kwambiri.
■ Onjezani kuziziritsa mpweya kapena kuziziritsa madzi ngati pakufunika.
