For the lowest cost fixture, lay out the PCB so that there is access from one side of PCB to at least one point on every network (net). Careful placement of through-holes can usually provide this. With this layout, you can test using a standard test head. Recommended target pad size is .035 inches (0.89mm) or larger. If you require probe access to both sides, special double-sided fixtures can be built. Double-sided fixtures are very common with SMT boards however they are more expensive.
