atg Luther & Maelzer GmbH extended its range of flying probe systems by launching a line for test areas of up to 40 ’’ width. The oversized test systems complement the standard line which can load boards with sizes of up to 27 ’’ width.

Special network technology and aerospace applications are driving the demand for high test coverage and 4-wire testing (Kelvin test) for large PCBs. However, 4– or 8-head solutions are not satisfying customer requirements for speed and throughput. The unique and industry architecture of the flying probe system 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, the company 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 40 ’’ x 40 ’’, 40 ’’ x 50 ’’ or 40 ’’ x 60 ’’.

The Sales Director for Europe and responsible Product Manager, Peter Brandt, highlights: “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.”
