Laum tawm lub qhov rau vias, dhau-lub-qhov khoom thiab mounting qhov. Kuv siv lub laum xovxwm nrog laum lwm rau cov xaim me me. Kuv pom tias pawg thawj coj saib xyuas tau yooj yim dua yog tias nws tau hlais ua ntej txiav mus rau qhov loj me.

Kauj Ruam 13: Txiav rau Qhov Loj Kawg

Siv lub rooj tsav xwm kab ntawv qhia ua kab lus, txiav lub rooj tsavxwm siv lub cuab yeej tig thiab txiav lub log, Cov ntaub ntawv ntug thiab puag ncig

Kauj Ruam 14: Sau koj Pawg Thawj Coj

Kuv ib txwm siv tes txuas cov khoom SMD ua ntej, tom qab ntawv vias thiab thaum kawg dhau los ntawm qhov-qhov sib xyaw.

Kuv tau ua cov cuab yeej no los tuav cov khoom SMD thaum siv los ntawm ob peb lub dowels qee lub tshuab ntxhua khaub ncaws thiab cov txiv ntoo. Kuv thov me ntsis cov kua ntws mus rau SMD cov pawm tuav cov khoom sib txuas cia tom qab ntawd muab tshuaj txhuam tso rau hauv qhov chaw.

Ib qho ua kom yuam kev rau qhov vias yog ua kom me ntsis ntawm cov xaim kawg nrog ib khub ntawm cov plyers kom lawv tsis txhob poob los ntawm ntawm qhov. Solder nyob rau sab xub ntiag tom qab khoov cov xaim hla thiab xaws tom qab.

Koj pawg thawj coj tau ua tiav thiab npaj tau los sim.

Kuv vam tias qhov kev qhia no txawm hais tias ntev tau pab tau. Thov koj xav kom muab cov lus pom zoo lossis tswv yim.

Ua tsaug rau kev siv sijhawm los saib kuv cov txheej txheem thiab muaj kev lom zem tsim koj cov phiaj xwm hluav taws xob.
