metalized

The tops of printed circuit boards and the bottoms and sides of discrete components are often made of a variety of metals or are coated with a thin layer of a metallic compound to make the surface-layer conductive.  These areas can then be soldered or further processed.  


Microchip

Microchip Technologies is an electronic component manufacturer based in North America.  Among their very popular offerings is the Atmel328P, the main microcontroller in the Arduino.


Minimum Order Quantity

The minimum order quantity is the absolute lowest number of parts that can be ordered at a time.  Below this quantity, the manufacturer or distributor's profit margins are so low, it doesn't make sense to invest employee time or company resources to sell the item.
