SEVERAL BREADBOARDING SYSTEMS USE PC boards with etched or stamped conductors that you cut and jumper according to your schematic. Other systems use socket buses into which you plug components and wires. While these are very convenient, time saving alternatives to conventional PC board layout and etching, sometimes less -disciplined methods are preferable. Improved layouts often result when IC's and other components can be positioned at nonparallel angles. Radio -frequency circuit optimization requires painstaking attention to lead length, positioning and shielding. A. F. Stahler Company (P.O. Box 354, Cupertino, CA 95014) manufactures tools and accessories that can be used to create a flexible bread boarding technique that overcomes these shortcomings for small -quantity development work. The basic concept is to create terminal islands within a larger sea of a single- or double -sided PC ground plane. Two tool types in three sizes each are used either to insulate or isolate terminal areas on the PC layout: The first, a series IS6000 isolated - pad -drill tool (shown), drills a pilot hole and a larger- diameter coaxial ring, leaving a component hole surrounded by an isolated terminal. Surface tension tends to prevent the melted solder from bridging the gap between the isolated terminal and the surrounding foil. A replaceable No. 60 or No. 69 bit is used to drill the component hole; and, depending on tool size, the outer concentric milling edges form a metal circle with a diameter of 0.01, 0.15 or 0.20 inch. The smallest- diameter tool is just right for drilling IC patterns with 100 -mil pin spacing. The recommended drilling speed is 600 RPM.
These drilling tools are also very handy if you want to modify existing PC boards; you can easily add pads to unetched areas.
