If you're going to share your home with a dog, you'll need to deal with some level of dog hair on your clothes and in your house. However, shedding does vary greatly among the breeds: Some dogs shed year-round, some blow seasonally -- produce a snowstorm of loose hair -- some do both, and some shed hardly at all.
The NSMD (non-solder mask defined) pads are finished with ENIG (electroless nickel immersion gold). The NSMD pad will permit better adhesion, with the solder being able to grip the sides of the copper, in addition to the top surface.
The term Solder Mask Defined Padâs relates to the method that controls the area in which molten solder is allowed to flow typically to an area larger than that was originally intended for the device solder pad. Non Solder Mask Defined pads (NSDM) are the usual way that a pad is designed. In that the originally intended device solderable pad size is maintained, except for a PWB trace joining the pad. Normally solder mask apertures are set such that they are between 0.05 & 0.075mm larger than the component solder pad per side.
