Backplanes: atg Luther & Maelzer releases the A7-20
atg Luther & Maelzer a company of Xcerra Corporation, announces the release and the first installations of the new A7-20 flying probe test system. Specifically designed for the demands of large format, high layer count backplanes, the A7-20 combines the flexibility typical for flying probe testers with accuracy and speed. The A7-20 significantly reduces test time and test cost.
The market segment for the A7-20 are large server and back panel designs for the telecommunication industry. These kinds of designs have up to 72 layers with a product weight of up to 30 kg (66 Ibs). 100.000 test points are very common on formats of up to 1.25 m (50 inches). In combination with higher density electrical test comes challenging. Traditional test solutions such as four-head probe systems or multiple oversized test fixtures for grid systems cannot fully meet the requirements in terms of speed and cost.
