Fixture Types The industry uses several standard tester platforms HP307x, GenRad 227x, Zenthel, Spectrum … Most common Fixture actuations Vacuum: In ICT application Vacuum actuation is the most used technic Pneumatic: For fixtures with a very large amount of probes pneumatic actuation is used. Mechanical: Mostly used in Functional applications. Most common hold-down mechanisms or Fixture Types are Backer Gate Vacuum Cover (Box) ZSK – Clamshell Mechanical/Linear Fixture Wired and Wireless (no wires) Fixtures 17 Traditional ICT Fixtures are wired from Test Probes to the Interface Panel. Sometimes a ICT Fixture is required in Wireless-Technology which means no wires are involved for transferring signals from the test points to the Tester. In this case there are double-ended test probes utilized in conjunction with a Transfer Board or Translator Board. The fixture stack-up is different to a traditionally wired fixture. There is no fixture pan involved like with a wired fixture. www.rns-usa.com
ICT vs. FCT ICT is board level test (component placement and value) 18 Lot of test probes Most board failures can be repaired In-circuit Test detects: Missing components Disorientation of components Improper value FCT is a functional test (performance test) Less test probes After board assembly is completed If performed without ICT, board failures can result in loss of complete assembly www.rns-usa.com
