High throughput for testing oversized PCBs

Special network technology and aerospace applications are driving the demand for high test coverage and four wire testing (Kelvin test) for large PCBs. However, four or eight head solutions are not satisfying customer requirements for speed and throughput.

The architecture of the atg Luther & Maelzer flying probe systems makes it possible to use a higher number of probes per test area resulting in faster test time and lower cost of test. To meet these requirements atg Luther & Maelzer launched the 16, 20 and 24 head machines with test areas of up to 40” width. Depending on the number of test heads, the resulting maximum test area sizes are 40x40”, 40x50” or 40x60”.

atg Luther & Maelzer Sales Director for Europe and Product Manager, Peter Brandt, stated: “The new systems make our high end test methods now also available for the test of oversized PCBs. When considering that the 24 head version allows up to 15,000 contacts per minute, it is a significant leap forward for our customers.”
