Flying-probe test systems support oversized test areas up to 40 by 60 inches
Wertheim, Germany. atg Luther & Maelzer GmbH announced it has extended its range of flying-probe test systems by launching a line that can accommodate test areas of up to 40 inches in width. The oversized systems complement the standard line, which can test boards with sizes of up to 27 inches in width.
Special network technology and aerospace applications are driving the demand for high test coverage and 4-wire testing (Kelvin test) for large PCBs, the company said. However, 4- or 8-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 GmbH launched the 16-, 20-, and 24-head machines with test areas of up to 40 inches in width. Depending on the number of test heads, the resulting maximum test area sizes are 40 x 40 inches, 40 x 50 inches, or 40 x 60 inches.
Peter Brandt, atg Luther & Maelzer sales director for Europe and responsible product manager, said, “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.”
