| I am looking for information on reflow temps for a flex board. There is only one 6 pin IC but the board has a 3M double sided tape. | Is it possible to reflow without damaging the tape. Any suggestions? Do you have a profiler for your reflow oven?

Some additional comments from a paper may be of interest. Baking Printed Circuit Boards - Why and How Baking printed boards prior to conventional and surface mount assembly should not be necessary. Often boards are baked for historical reasons; in

Does anyone have any data pertaining to contaminates baking out of a fiberglass resin pallets used for processing flex circuits? If so does this phenomena increase over time? Thanks,

Mike: We have provided many carriers for flex circuit applications to facilitate processing through screen print, pick-and-place and reflow and, in many cases, eliminating the need for taping the flex circuit to the carrier. Please contact me and w

At a previous job I had been taught that when reflow soldering polyimide flex circuits, it was necessary to pre-bake them before reflow soldering to prevent delamination. Our procedures said that there must be a 1hr bake prior to reflow, and the flex

IPC-FA-251 recommends 121*C for 30-60 minutes for 1 and 2 flex layer circuits. A rigid flex can take easily an hour per layer depending on the construction.

I think that the IPC spec only apply to the MSD. I had a paper from Lucent and forwarded by Francois Monette, please aware that the first 2 hours, the moisture doesn't bake out from the assembly/component and result show that it is increase the weigh

I have used conductive adhesives for some time now on thickfilm. Does anyone know of a really good conductive adhesive to attach flip chips to flex circuits? I would like to stencil print the adhesive to the substrate and then place the flips chips
