The leading supplier of bare board test systems
PCB and substrate test systems
We offer a wide range of different test technologies starting from prototype testing up to mass production test.
Under the atg and Luther & Maelzer brands, we offer a wide range of different test technologies for the test of unpopulated PCB starting from prototype testing up to mass production tests.
atg’s Flying Probe Systems feature a unique multi-rail concept, which allows test systems with up to 24 test heads. It guarantees an outstanding throughput in the process of electrical testing, especially when combining the tester with an automated handling system.
High throughput
Although automated Flying Probe solutions nowadays can be applied economically even for mid-size production volumes, high-volume production often requires fixture-based test solutions. Under the Luther & Maelzer brand we offer Universal Grid Test Systems with grids ranging from double density to octal density (35mil), test areas up to 325 mm x 244 mm (12.8″ x 9.6″) and PCB sizes up to 400 mm x 300 mm.
These combine easy and fast fixture building, simple operation and high throughput. Optical alignment and micro adjustment provide the functionality required for testing small pad sizes and dense structures. The option to use alternatively Dedicated fixtures e.g. for Kelvin test of HDI PCB on the same systems lets our customers always choose the most cost-efficient technology.
