Abstract
A printhead assembly with a replaceable stylus insert provides for compact connection of contact pads by staggering the contact pads an offset distance that is significantly less than the pad dimension in the direction of offsetting. Preferably the offsets are symmetrically arranged about a reference line and connections are coordinated relative to the reference line so that conductor overlaps are avoided. A compressable means applies pressure to urge the contact pad into intimate engagement and ribs formed in one or both of two clamping sections concentrate pressure along alignments of contact pads.
