Abstract: A vertical probe assembly having a resilient compliant probe, a first guide plate, a second guide plate, and a third guide plate is disclosed. The probe may include an upper portion, a lower portion, and a stopper structure positioned between the upper and lower portions of the first probe. The first, second, and third guide plates may be formed from a non-conductive substrate and separated by one or more spacers. The first, second, and third guide plates may also include a first, second, and third hole, respectively. The first, second, and third holes may be vertically aligned. The probe may be positioned within the first, second, and third holes such that the upper portion extends through the first hole, the lower portion extends through the second and third holes, and the stopper structure contacts a surface of the second guide plate that faces the first guide plate.
