These pins have a retaining dimple that keeps the pins
from falling out of the fixture (see illustration). they are capable of
testing SMD products on centers of: .050, .040, .025, and as low as .010
mil. they also allow testing of high density boards with the standard .100
mil. grid. It is possible to fan the pins up to .400 inches off center,
and still maintain excellent contact. The use of a three plate system is
recommended.
Custom designs can also be supplied.
