Abstract

A method is described for assembling a multilayer planar object, such as a circuit board. The arrangement relies on a combination of four key items. 1) A carrier plane (or two) called a core shown in Fig. 1 with locating slots 10. Four slots are required for best location, although only three slots may be used for planar location which is to be fixed. 2) A set of three unique plunger-tapered pins 11 shown in Fig. 2 are the locating devices. These pins 11 are suspended on leaf springs 12 or sheet metal and will exhibit zero backlash in the slots and provide excellent repeatability and non-stick reliability, requiring no maintenance. 3)
