Hi All.

Need some immidiate help. I need to know any / all basic info regarding Teflon PCBs. Any special requirements for assembly on SMT and thru-hole lines, like profiles, placemnt , wave etc. Will there be some basic / big differences in comparision to FR4 ?

Thanks.

What material are you using? There are a great deal of different Teflons (in the family of Teflons) material....is it from Gore or Rodgers???? Does it have aluminum backing??

More information necessary,

Kevin

Depending on the type of teflon material, thickness, and reflow profile requirements, these will have a direct bearing on your maximum process allowable PCB pallet size.

You'll want to be careful on how big the PCB or pallet is. Larger teflon PCBs processed in a reflow oven on rails will tend to flex in a standard Sn63 profile unless properly supported or fixturized.

More specific info is needed about your machines and PCB attributes in order to provide appropriate responses.
