MSD yog cov tsiaj ntawv ntawm dej-sensitive ntaus ntawv. Nws yog s uas tsis yog-hermetic ntim caij thiab ua los ntawm ib tug dej-permeable khoom xws li ib tug tuab yov caij thiab ib tug pob daim phiaj arry.
Thaum cov dej -sensitive ntsiab raug txhawb siab kub thaum lub sij hawm reflow soldering,
ya raws hauv lub suface ntawm cov yas suface mount ntaus ntawv (SMD) yuav ua tau kom loj vapor siab puas tsuaj los yog tawg. Yuav ua li cas loj tuaj lawm, cov keej yuav cuag mus nto ntawm cov tivthaiv, ua su los yog tawg. Yog li ntawd nws yog ib qho tseem ceeb thiab neccessary rau dej pov thawj ntim.
Dhau li ntawd, nws tseem yog ib qho tseem ceeb yuav coj precausions yuav nqus noo noo nyob rau hauv lub pob. Uas yog vim li cas koj feem ntau pom cov desiccant hnab hauv cov caij ntim. Montmoirllonite av nplaum desiccant yog heev haum rau hluav taws xob cov khoom. Nws ua los ntawm tej yam ntuj tso montmoirllonite av nplaum, nrog environmentally, uas tsis yog-tshuaj lom, thiab reactively featurers. Lub packing ntawv yuav siv sij hawm muaj zog tvyek ntawv, nws yog tawv, thiab anti-static. Montmorillonite av nplaum desiccant muaj muaj zog ya adsorption peev xwm .can zoo thiab welly ua si lub luag hauj lwm ntawm dej pov thawj, tus ceev xwm ntawm cov khoom muaj kev ruaj ntseg thiab zoo.
