Flying probe test system handles oversized pcbs

The range of Flying Probe test systems at atg Luther & Maelzer has been extended with a line for test areas of up to 40in. width. The oversized systems complement the standard line which can load boards with sizes of up to 27in. 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 architecture of the 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 40in. width.

Depending on the number of test heads, the resulting maximum test area sizes are 40in.x40in., 40in.x50in. or 40in.x60in.
