一般電路板上的IC封裝零件都會定義其 MSL(Moisture Sensitivity Level,濕敏等級),可是有許多的朋友似乎還是不太瞭解MSL的目的及其定義。 首先,我們要知道MSL分類的目的主要在避免封裝零件(一般指IC封裝零件)流經「Reflow oven(回焊爐)」時快速升溫後不會造成零件「分層效應(Delamination)」產生。 那為何封裝零件流經高...
For example, when we look at Cooperstown Airport, this 1,424 number indicates that the airport sits at 1,424 ft mean sea level (MSL). When it comes to towers and other obstructions, these are what they look like on a Sectional Chart. Check out this lighted tower. You will see “1049...

The MSL is applicable only for surface mount ICs that are plastic encapsulated. ICs need to stay dry so they can be soldered. If they exceed their moisture level, they can be baked prior to soldering. However, the DMD are not soldered so it doesn’t fall under the typical Moisture Se...
We, here, used the Level-2A product obtained from GEE (dataset ID: “COPERNICUS/S2_SR”) to extract spectral features and classification, which is an orthorectified and atmospherically corrected surface reflectance data set. We utilized 12 bands from the Sentinel-2 image and resampled all bands...
