1. SOLDER Muab cov teeb meem no;
Cov kev ua si tsis muaj kev ua si yuav ua rau los ntawm kev siv ntev ntawm cov ham muab tshuaj txhuam, uas tau txais cov neeg sawv cev nquag ua haujlwm. Ib qho ntxiv, yog tias cov cam muab tshuaj txhuam hniav yog qhov loj dhau los dhau ntawm tus hlau mesh ntau dhau, nws yuav ua rau muaj teeb meem PCBA cua sib dhos. Cov cua soldering tshwm sim los ntawm solder muab tshuaj yuav tuaj yeem hloov kho los ntawm kev hloov cov khoom siv ntaus pob ntau dua lossis hloov lwm cov pas dej ua ke nrog cov hmoov av me;
2. PCB thiab cov teeb meem hluav taws xob;
PCB Circuit Coffic Boards thiab Cheebtsam hluav taws xob yuav cuam tshuam los ntawm ya raws, dej noo, thiab lwm yam, uas yuav ua rau muaj teeb meem PCRA. Cov hau kev txhim kho tau suav nrog kev txhim kho ib puag ncig ntawm PCB thiab Cheebtsam hluav taws xob, thiab tswj qhov chaw cia khoom. Qhov kub thiab cua sov kom tiv thaiv cov kev tsheb ciav hlau nrog hluav taws xob thiab cov khoom siv los ntawm kev nqus dej lossis oxidized.
3.Txhua teeb meem
Muaj ob qho laj thawj tseem ceeb: txhaws ntawm lub stencil mesh thiab tsis txaus ntseeg mesh. Lub clogging ntawm tus stencil mesh yuav ua rau cov ham muab tshuaj kom tsis muaj peev xwm luam tawm ntawm Circuit Coffe. Tsis txaus ntseeg mesh qhov raug ua rau tus ham muab luam tawm kom ua haujlwm. Cov hau kev rau kev txhim kho muaj: nce qhov zaus ntawm kev ntxuav SMT cov raj hlau, thiab xyuas kom meej tias cov ntxaij hlau raug ntxuav kom ua ntej kev hloov kho, thaum siv, thiab tom qab siv. Tshwj xeeb tshaj yog thaum siv, tus mesh steel yuav tsum raug muab ntxuav kom tsis tu ncua raws li qhov xwm txheej; Tsis tas li ntawd, thaum qhib thaum txhim kho Stencil, qhov tseeb ntawm stencil mesh yuav tsum tau kom ntseeg tau;
