Test apparatus for testing operation of a printed circuit board

摘要

A test apparatus includes lower and upper spacer discs for sandwiching and securing a printed circuit board therebetween, lower and upper plates, and a two-step driving mechanism. The lower and upper spacer discs are spaced apart from the lower and upper plates. Activation of the test apparatus in a first step results in relative movement between the spacer discs to sandwich the circuit board therebetween. Activation of the test apparatus in a second step results in relative movement between the lower and upper plates to sandwich the upper and lower spacer discs therebetween.
