We just use stare titanium stiffeners from the wave soldering area. Titanium is probably over-kill for your needs, but will work. Sources for titanium stiffeners are: * APT 603.622.1211 Tom Dimagio * New Era Technology 603.669.77971 Jessie Ward * B

We use the epoxy gold finger gloves. They are cheap and can be cut to length. We get them from; Stevens Products, Inc 973-672-2140

Hi Folk's, a quick and easy? question. Got a card with PTH edge stiffeners fitted to it so we need to flow solder them. Having problems getting hole fill, mainly I think due to 2 things, poor pin to hole ratio and also a bit of oxide. The question i

A bit of gray area for you. consider the application over the specmanship. Why are the stiffeners there in the first place? Is the rigidity requirement a high function i.e. very necessary due to potential shock and vibration , etc.? The soldering is

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

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

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
