  • Productivity High-accuracy step-tester for universal and dedicated fixture designs
  • Stability 2 cameras for top/bottom offset compensation
  • Flexibility Advanced 4-wire, µShort and voltage drop measurement methods


The LM1000 is a highly precise compact step tester for the electrical test of HDI bare boards in mass production.

The solid granite frame provides the highest accuracy. Two high-resolution cameras (top and bottom) scan the PCB and enable the automatic micro-adjustment of the fixtures. 

The dual shuttle and a dual vacuum grabber – driven by fast linear motors – provide high throughput multi-tasking product handling. The machine runs either with universal fixtures up to 6.4″ x 9.6″ test area or with a dedicated fixture.

This gives the customer the possibility to choose the best price-performance technology for the specific application without being limited by the equipment.
