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.
What Are SPDs. A surge protective device (SPD) is a protective device for limiting transient voltages by diverting or limiting surge current and is capable of repeating these functions as specified. SPDs were previously known as Transient Voltage Surge Suppressors (TVSS) or secondary surge arrestors (SSA). Secondary surge arrestor is a legacy term (often used by utilities) and is used most commonly for a device that has not been certified to ANSI/UL 1449. In 2009, after the adoption of ANSI/UL 1449 (3rd Edition), the term Transient Voltage Surge Suppressor was replaced by Surge Protective Device.
