Buckling beam probe arrays and methods for making such arrays including forming probes with lateral positions matching guide plate hole positions

Abstract

Embodiments are directed to the formation of buckling beam probe arrays having MEMS probes that are engaged with guide plates during formation or after formation of the probes while the probes are held in the array configuration in which they were formed. In other embodiments, probes may be formed in, or laterally aligned with, guide plate through holes. Guide plate engagement may occur by longitudinally locating guide plates on probes that are partially formed or fully formed with exposed ends, by forming probes within guide plate through holes, by forming guide plates around probes, or forming guide plates in lateral alignment with arrayed probes and then longitudinally engaging the probes and the through holes of the guide plates. Final arrays may include probes and a substrate to which the probes are bonded along with one or more guide plates while in other embodiments final arrays may include probes held by a plurality of guide plates (e.g. 2, 3, 4 or even more guide plates) with aligned or laterally shifted hole patterns.
