Bare Board testing of Electrical test-flying probe testers

At Hopetimepcb we test all bare boards with flying probe testers, avoiding long set up times and high tooling costs for adapters. We test for shorts and opens.Bare Board Testing or Electrical Testing of the non populated circuits board is a test that ensures the working of the circuit of your PCB by testing it to the electrical footprint of your design. It is standard in the PCB production process of Hopetimepcb with exception of the single layer boards where it is optional.

Electrical Test
At the end of the PCB production process we use electrical test to check the interconnectivity of the PCB is correct against the original board data.Using a flying probe tester we check each net to ensure that it is complete (no open circuits) and does not short to any other net.The flying probe testers in our quality control department are easy to set up as they don’t need a test fixture but testing every net is slow.
A faster test method is the Acceler8.  This uses 4000 tiny probes like a brush.  It builds an electronic map of the PCB from a pre-tested good board.  Then it compares each board to be tested with its map.  This cuts test times by 90%.For double sided boards electrical test is an option.
