Hi Thomas, Thank you for your posting and I agree with you that Printing is the most difficult one. BTW, after you ran the one side (let's say Bottom side), my engineer worries about the distortion of flex board because of the thickness. In that ca

A good set of fixtures are what you need to get it done right. Since we are in the same area, I would recommend give ATD (Advance Tooling Design)a try, they located in San Jose. We been using fixtures from them for years. We build thousands of Fle

Hi Thomas, Thank you for your advice. BTW, unfortunately, I received negative answer from the Fixture house same as below. =========== We have an issue here. Your board is too thin. It is fine to make the fixture for first side. But when you run

We run stiffeners on all of our product through our wave solder process and most of our product through our reflow and adhesive cure oven. The problem is we continually put on and take off stiffeners because of poor reliability of stiffeners staying

Hi, 1. I will run the board on the mesh if single sided. 2. For double sided board, I will try stiffeners. 3. If stiffeners don't work, then you have to create a handling fixture(holds the board and has enough openings to let the air flow to the PC
