I know a few here have had circuit boards made either as prototypes or small runs but has anyone ever had flexible PCBs made (flexible circuit ribbons) or know of any reliable places that may do this? The reason I ask is that I'm looking into the possibility of making some ribbon isodynamic drivers along the lines of the old Wharfedale Isodynamics. I've found some sources of high energy flexible magnets that can be cut/punched/drilled and formed to shape. If I can get a set of flex PCBs made I'll be good for prototyping the drivers.

I made some ribbon/planar phones using flexible laminates for my ribbons a while back.
Still got my old Wharfdales too!
Getting thin enough laminates in small quantities can be difficult.

You will need to look for the thinnest copper on polymide [adhesive-less] you can find.

I have attached a pic of my driver, though the ribbon i ultimately used has a lot less traces on it.

Good luck , it is a fun project to do.

Try Samtec, i was gonna have some flex circuits done by them for a work project, but it took a different route so never got them made.
I have used a lot of their other products though, which have been very good quality.
No matter who we had quotations off they were all quite expensive unfortunatlly.

Hey setmenu, long time no see

I don't know if you've been following the ortho thread at all but after three long years I finally found a set of Wharfedales. I refurbed them and now they're as good as new. It's great to have them again after all these years! Awesome phones and design too. That's why I want to see if they can be reproduced in any way. It's nice to see you kept up with your ribbon drive, you were the inspiration to try this but I thought you had dropped off the radar long ago.
