Qhov zoo ntawm Reflow Soldering Thiab Kev Ceeb Toom Rau Kev Kho
Qhov zoo ntawm reflow soldering thiab ceev faj rau kev saib xyuas
Dab tsi yog qhov zoo ntawm reflow soldering txheej txheem technology?
(1) Thaum reflow soldering tshuab yog siv rau soldering, nws tsis yog yuav tsum tau rau immersed lub Circuit Court board nyob rau hauv lub molten solder, tab sis ua kom tiav cov hauj lwm soldering los ntawm cov cua sov hauv zos; Overheating ua rau cov khoom puas.
(2) Txij li thaum vuam tshuab tsuas yog yuav tsum tau siv cov vuam vuam ntawm qhov vuam thiab ua tiav cov vuam los ntawm cov cua sov hauv zos, cov vuam tsis xws li kev sib tsoo yog zam.
(3) Nyob rau hauv cov txheej txheem reflow soldering, lub solder tsuas yog siv ib zaug xwb, thiab tsis muaj rov qab siv dua, yog li ntawd lub solder yog huv si thiab tsis muaj impurities, uas ua kom zoo ntawm cov pob qij txha.
Kev ceev faj rau reflow soldering tu
Txhawm rau kom tsis txhob muaj kev tu lub qhov cub tsis raug, uas yuav ua rau tawg lossis tawg, nws yog txwv tsis pub siv cov kuab tshuaj tsis zoo los ntxuav lub qhov cub sab hauv thiab sab nraud. Yog tias nws tsis tuaj yeem zam kom tsis txhob siv cov kuab tshuaj hnyav xws li cawv, isopropanol, thiab lwm yam, thov xyuas kom meej tias cov tshuaj no evaporate ua ntej ntxuav. Cov khoom siv muaj. Ua ntej kev saib xyuas, vuam flux, plua plav, av lossis lwm yam khoom txawv teb chaws ntawm txhua qhov yuav tsum tau ntxuav thiab oiled! Kev saib xyuas tshwj xeeb yog thaum peb tab tom ua haujlwm txhua hnub ntawm kev rov ua haujlwm rov qab, yog tias peb pom tias lub tshuab ua haujlwm tsis zoo, peb tsis tuaj yeem kho nws yam tsis tau tso cai, thiab peb yuav tsum ceeb toom rau cov neeg ua haujlwm tswj cov cuab yeej hauv lub sijhawm los daws nws. Nyob rau tib lub sijhawm, koj yuav tsum tau xyuam xim rau kev ua haujlwm nyab xeeb thaum lub sijhawm tu, thiab tsis txhob ua haujlwm tsis tu ncua.
