Hi, We are placing a Surface Mount connector on a flex circuit, we are planing on using SMT carriers to support the flex through the SMT process. Underneath the connector a stiffener needs to be adhere, I'm not sure if we should have the flex manu

To me the most challenge would be the printing step. If you can print it, you should able to run it with SMT. We ran similar thickness flex boards before. But it's long flex with small stiffener at both ends, and it was 10up array. You need fixture

Is the stiffener a piece of FR4, or a component that needs to be installed? We've done a number of flex assemblies taht have a rigid stiffener, generally a piece of rigid flex, or FR4 that has the components mounted on it. This type of stiffener

Absolutely I will share the solution with you if I find something. Thomas, thank you for your help. Have a great weekend!

Good Afternoon, How is the stiffener adheared? If it is laminated to the flex, it may help you with the surface planarity through reflow. If it put on with PSA, it may cause more problems then it would solve. PSA gets soft through the reflow. It may

I am sorry to hear that they are unable to help you out too. If you do came up with the doable solution later, be sure to let me know about it too. I would like to learn new trick or knowing which house that can handle such task.

Is there any special machines/equipment which are able to install FBGA parts on the very thin flex boards for Printing, Pick & Place, and Reflow ? Q2> Is there any Fixture house who can offer fixtures to enable SMT processes for those assemblies ? Q

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
