Improved printed circuit boards and methods of soldering them are provided in which a snap bar is provided on the conductor side of a printed circuit board for reducing defects, such as bridging, during soldering. This and other provided process and design techniques, such as lead lengths, orientation, mask finish, and the location of the leads on the board, have significantly reduced reworking and defective components and are especially effective when applied to 50 mil connector products.
