Inde.Chitsulo chosapanga dzimbiri cha 304 chimatha kugulitsidwa bwino mkuwa mu vacuum pogwiritsa ntchito mitundu yosiyanasiyana ndi zowonjezera zamadzimadzi (BFM).Filler zitsulo zochokera golide, siliva ndi faifi tambala akhoza kugwira ntchito.Popeza mkuwa umakula pang'ono kuposa 304 zitsulo zosapanga dzimbiri, chidwi chapadera chiyenera kuperekedwa pakukhazikitsa kolumikizana.Pankhaniyi, mphamvu yamkuwa idzakhala yochepa kwambiri, kotero imatha kukwanira zitsulo zosapanga dzimbiri popanda mapindikidwe oonekera.
Misonkhano ya brazed imagwira ntchito pa kutentha mpaka 4 ° Kelvin.Pali zolingalira ndi zoperewera, koma zitsulo zagolide ndi siliva zimagwiritsidwa ntchito kwambiri pakugwiritsa ntchito.
3. Ndikufunika solder msonkhano wovuta, koma sindikudziwa momwe ndingagulitsire zonse mwakamodzi.Kodi kugulitsa magawo ambiri kumatheka?
Inde!Katswiri wothandizira solder amatha kukonza njira zambiri zogulitsira.Ganizirani zazinthu zoyambira ndi BFM kuti cholumikizira choyambirira chisasungunuke pakuthamanga kotsatira.Kawirikawiri, kuzungulira koyamba kumayenda pa kutentha kwakukulu kusiyana ndi maulendo otsatila ndipo BFM sichibwereranso m'mizere yotsatira.Nthawi zina BFM imagwira ntchito pogawa zosakaniza mu gawo lapansi kotero kuti kubwereranso kutentha komweko sikungayambitsenso kusungunuka.Multi-step soldering ikhoza kukhala chida chosavuta komanso chothandiza popanga zida zachipatala zodula.
Vutoli litha kuthetsedwa!Pali njira zopewera izi, njira yabwino kwambiri ndikugwiritsa ntchito kuchuluka koyenera kwa BFM.Ngati chophatikiziracho ndi chaching'ono komanso chaching'ono m'derali, zingawoneke zodabwitsa kuti BFM imafunika bwanji kuti igulitsidwe bwino.Werengani ma kiyubiki malo ophatikizana ndikuyesera kugwiritsa ntchito BFM yochulukirapo kuposa malo owerengeredwa.Mapangidwe a pluggable yoyenera ndi socket yotopetsa, yofanana ndi m'mimba mwake ya chubu, yomwe imalola BFM kusuntha molunjika kumimba yamkati ya chubu ndi capillary action.Siyani malo kumapeto kwa chubu kuti muteteze capillary, kapena pangani kugwirizana kotero kuti chubu likhoza kutuluka pang'ono kupyola malo olumikizira.Njirazi zimapanga njira yovuta kwambiri kuti BFM ipite kumapeto kwa chitoliro, motero kuchepetsa chiopsezo chotseka.
Mutuwu umabwera nthawi ndi nthawi ndipo umayenera kukambidwa.Mosiyana ndi ma solder fillets, omwe amapanga mphamvu mu olowa, ma solder fillets samawononga BFM ndipo amatha kuvulaza.Chofunika ndi zomwe zili mkati.Ma PM ena amakhala osasunthika m'mafupa akulu chifukwa cha kuchuluka kwa zinthu zomwe sizimasungunuka.Pankhaniyi, ngakhale kutopa pang'ono, fillet imatha kusweka ndikukula mpaka kulephera koopsa.Pamene soldering, pang'ono, mosalekeza kupezeka kwa BFM pa olowa mawonekedwe nthawi zambiri muyeso woyenera kwambiri kuyendera maso.
