1. Txuas cov ntaub qhwv mus rau hauv lub qhov.Nyob rau hauv txoj cai, cov xov hlau nruab nrab ntawm lub mounting pads thiab ntawm lub qhov yuav tsum tau soldered.Tsis muaj lub npog ntsej muag yuav ua rau cov khoom siv vuam tsis xws li cov tin tsawg dua hauv cov pob qij txha, vuam txias, luv luv Circuit Court, cov pob qij txha tsis muaj kev sib txuas, thiab cov pob zeb tombstones.

2. Kev tsim lub ntsej muag lub ntsej muag ntawm cov ntaub qhwv thiab cov ntaub qhwv ntsej muag cov qauv tshwj xeeb yuav tsum ua raws li tus qauv tsim ntawm cov khoom siv hluav taws xob ntawm cov khoom tshwj xeeb: yog siv lub qhov rais-hom solder tiv thaiv ntawm cov ntaub qhwv, lub solder tiv taus yuav ua rau lub solder. nruab nrab ntawm cov pads thaum soldering.Nyob rau hauv cov ntaub ntawv ntawm luv luv Circuit Court, cov ntaub qhwv yog tsim los kom muaj kev ywj pheej solder resists ntawm tus pins, yog li yuav tsis muaj luv luv Circuit Court ntawm cov ntaub qhwv thaum vuam.

3. Qhov luaj li cas ntawm lub npog ntsej muag lub ntsej muag ntawm cov khoom tsis tsim nyog.Kev tsim qauv ntawm lub ntsej muag lub ntsej muag uas loj dhau yuav "tsim" ib leeg, ua rau tsis muaj lub npog ntsej muag, thiab qhov sib txawv ntawm cov khoom me dhau.

4. Muaj cov qhov nyob hauv qab cov khoom uas tsis muaj lub npog ntsej muag, thiab tsis muaj lub npog ntsej muag ntawm lub qhov hauv qab cov khoom.Lub solder ntawm lub qhov ntawm qhov tom qab yoj soldering yuav cuam tshuam qhov kev ntseeg ntawm IC vuam, thiab tej zaum kuj yuav ua rau luv luv Circuit Court ntawm Cheebtsam, thiab lwm yam.
