Inde. Chitsulo chosapanga dzimbiri cha 304 chikhoza kugulitsidwa bwino ku mkuwa mu vacuum pogwiritsa ntchito mitundu yosiyanasiyana ndi zowonjezera za mankhwala (BFM). Zitsulo zodzaza zochokera ku golide, siliva ndi nickel zingagwire ntchito. Popeza mkuwa umakula pang'ono kuposa chitsulo chosapanga dzimbiri cha 304, chisamaliro chapadera chiyenera kuperekedwa ku kasinthidwe kolumikizira. Pankhaniyi, mphamvu ya mkuwa idzakhala yochepa kwambiri, kotero imatha kuyika chitsulo chosapanga dzimbiri popanda kusintha kooneka.
Zomangira zomangira nthawi zambiri zimagwiritsidwa ntchito kutentha mpaka 4° Kelvin. Pali zinthu zina zofunika kuziganizira komanso zoletsa, koma zitsulo zodzaza zopangidwa ndi golide ndi siliva zimagwiritsidwa ntchito kwambiri pa izi.
3. Ndikufunika kusoka chinthu chovuta, koma sindikudziwa momwe ndingasokerere chilichonse nthawi imodzi. Kodi kusokoka kwa zigawo zingapo ndikotheka?
Inde! Katswiri wopereka soldering akhoza kukonza njira yosoldering ya masitepe ambiri. Ganizirani za maziko ndi BFM kuti cholumikizira choyambirira chisasungunuke pakapita nthawi. Nthawi zambiri, kuzungulira koyamba kumachitika pa kutentha kwakukulu kuposa kuzungulira kotsatira ndipo BFM siisungunuka pakapita nthawi. Nthawi zina BFM imagwira ntchito kwambiri pofalitsa zosakaniza mu substrate kotero kuti kubwerera kutentha komweko sikungayambitse kusungunuka. Kusoldering ya masitepe ambiri kungakhale chida chothandiza komanso chothandiza popanga zida zamankhwala zodula.
Vutoli lingathe kuthetsedwa! Pali njira zopewera izi, njira yabwino kwambiri ndikugwiritsa ntchito BFM yokwanira. Ngati cholumikiziracho chili chaching'ono komanso chaching'ono, zingawoneke zodabwitsa kuti BFM ikufunika kuti cholumikiziracho chigwirizane bwino. Werengani dera la cubic la cholumikiziracho ndipo yesani kugwiritsa ntchito BFM yochulukirapo pang'ono kuposa dera lomwe lawerengedwa. Kapangidwe ka cholumikizira cholumikizira ndi soketi yoboola yomwe ili yofanana ndi ID ya chubu, zomwe zimalola BFM kusuntha mwachindunji ku ID ya chubu pogwiritsa ntchito capillary action. Siyani malo kumapeto kwa chubu kuti mupewe capillary action, kapena pangani cholumikiziracho kuti chubucho chituluke pang'ono kupitirira malo olumikizirana. Njira izi zimapangitsa kuti BFM ikhale yovuta kwambiri kuti iyende mpaka kumapeto kwa chitoliro, potero kuchepetsa chiopsezo chotseka.
Nkhaniyi imabwera nthawi ndi nthawi ndipo imafunika kukambidwa. Mosiyana ndi ma fillet a solder, omwe amapanga mphamvu mu cholumikizira, ma fillet akuluakulu a solder sawononga BFM ndipo akhoza kukhala oopsa. Chofunika ndi chomwe chili mkati. Ma PM ena ndi ofooka mu ma fillet akuluakulu chifukwa cha kuchuluka kwa zigawo zosasungunuka zomwe sizimafalikira. Pankhaniyi, ngakhale mutatopa pang'ono, fillet imatha kusweka ndikulephera kwambiri. Pakulumikiza, kupezeka pang'ono kwa BFM pamalo olumikizira nthawi zambiri ndiye muyezo woyenera kwambiri wowunikira maso.
