Since ProtoShield sheets are depth-etched with a checkerboard pattern for folding, they can be easily formed into many diverse configurations. In the product development stage, fully functional shields can be created in minutes with just a pair of scissors and a straight edge for folding – saving both time and money. ProtoShield sheets are offered in two sizes. The Standard version has .25″ squares and the Metric version has 5mm squares. Both versions are solderable and corrosion resistant due to nickel silver material. No finishing or plating is necessary. ProtoShield prototypes can be direct soldered to the board or shield clips can be used for easy mounting.
