AETRIUM TK CONTACTORS

Aetrium’s TK series true kelvin contactors are ideally suited for high volume production testing of leadless and leaded packages, and are adaptable to meet a variety of test arrays and handler types.  The unique construction methods enable very high inter-lead resistance as well as superior pin placement accuracy.  This results in more consistent measurements and as a result, higher yields.
