Trace breadth is a very important style parameter in PCB style. Adequate trace breadth is important to make sure the specified quantity of current will be transported while not heating and damaging your board. you'll use this on-line tool to calculate AN estimate of the minimum trace breadth for a given current and copper weight. a better current needs thicker traces whereas a thicker copper weight permits for diluent traces.

The layer on high of the copper foil is termed the soldermask layer. This layer provides the PCB its inexperienced (or, at SparkFun, red) color. it's overlaid onto the copper layer to insulate the copper traces from accidental contact with alternative metal, solder, or semiconducting bits. This layer helps the user to solder to the right places and forestall solder jumpers.
