All BETON produced PCBs(Incluede Multi-layers PCB, HDI PCB, High frequency PCB, Metal core & Alu PCB, Flexible PCB, Rigid-Flex PCB) will make 100% AOI (Automated Optical Inspection) after doing the circuits production to make sure that all circuits and pads are connected and no open or short happened. 

In addition to this, the final finished samples PCBs also will be tested by the flying probe machine to make sure that all vias are connected, and mass production PCB will tested with test fixture to assure all function OK and no open and short, because this is not visible by the AOI. Single layer PCB do not require this test because there are no vias but boards with 2 layers and above will always be 100% tested with a flying probe and E-test fixture.

So no worries about the PCB function quality issues, as we have implement the 100% E-Test for all PCBs, and all the defect PCBs can be blocked before shipment. and all the PCB deliver to customer side will be the all OK boards, so any doubt about the PCB E-Test or need PCB E-Test fixture please contact us freely for know more, Email address: [email protected]
