Hi fellow problem solvers,... We suspect a planarity problem with our 6 mil wide flex circuit pads having height variance of up to 2 mils after print and reflow. This is contributing to a placement skew with our TAB bonder... Has anyone had any succe

Hi, I would not be too concerned about what the shape of your wirebonding fiducial is. Cross, Square, Diamond, Circle, will all work well for you. I use a "+" and a diamond. Your machine magnification will be great, so don't make the fiducials to
