PCB Test

atg Luther & Maelzer

Leading Supplier of Bare Board PCB Test Systems

Bare board PCB test systems are used to test pre-assembly printed circuit boards. Our PCB test systems include flying probe testers, which are used to test low-volume, highly complex circuit boards and do not require the use of a separate test fixture, as well as universal grid testers, which require the use of a separate test fixture and are well suited to test circuit boards in high volume manufacturing.

atg-Luther & Maelzer, is a company of Cohu and  is the leading supplier of electrical testing solutions for the Printed Circuit Board industry with solutions for every application regardless of product type, batch size or technology deployed. atg Luther & Maelzer offers Flying Probe Testers and Universal Grid Testers.
