What is a Solder? A solder is an alloy that melts at relatively low temperatures and is used to join or seal metals with higher melting points. A metal alloy with a melting temperature below 427°C (800°F). Read More
What is the Smallest Hole? This is the final size of the hole. We will select a drill larger than the specified hole size to allow for plating thickness. Hole sizes greater than 0.020″ do not incur special costs. Read More
What are Slots / Cutouts? Slots are internal cutouts usually long and thin. By selecting Slots we will add up to 5 slots per board. If your design has more than 5 slots, additional costs may be needed. Read More
Size X & Y All dimensions are in inches. If your board is in metric, please convert to inches. Read More
