These boards have an ENIG surface finish and are made from high quality FR4 which can withstand high temperature soldering and re-work. The holes on this prototyping PCB have a standard 0.1" pitch to enable compatibility with a large variety of electronic components. The space between the power rails and the adjacent rows is 0.15". Each hole is electrically connected to a row of holes to make building circuits fast and easy. See the drawing below for a detailed view of the electrical connections on this board. Both sides of this board have solder mask, making it easier to control solder flow and prevent unintentional bridges. Mechanical Drawings Electrical Connections This protoboard is broken up into rows of six electrically connected holes with a full length power rail on each side. All electrical connections are shown in the drawing above. Custom Designs Can't find what you need? We can design and produce a custom board to fit your exact needs.
