Cov kev lag luam twg tsis ua hauj lwm tag nrho nws ua rau kev puas tsuaj rau cov yas deformation, kev tiv thaiv kev tsis ncaj ncees. Thaum siv cov hlua txuas ntawm pin thiab teeb cov teeb liab, peb yuav tsum ua tib zoo saib xyuas cov ntsiab lus hauv qab no. Vim tias nws yooj yim kom muaj qhov hloov piam sij yog tias tsis ua haujlwm.
1. Siv cov hluav taws xob fais fab hnyav thiab vov ceev ceev. Peb xav kom koj siv 30Welectric soldering hlau thiab suaj tom qab 2 feeb thaum nws ncav cuag 320 ℃.
2. Siv cov nyiaj ntau ntawm cov hmoov txhuam thiab muab tus pin-terminals txo qis thaum lub sam fais fab.
3. Nws yog qhov zoo dua los siv cov hlua txuas dua li ncaj qha vuam.
