Design Rules / materials 

The standard Design Rules for 3D technology summarise all the important key parameters you need to make your project a success and to apply this dependable technology.

Materials 

  • Flex material: polyimide 50µm    
  • material: FR4 cores, FR4 prepreg 
  • Adhesive: acrylic adhesive or epoxy no-flow 

Covering the flex area

  • 1F/2F/4F: flexible solder-stop foil 
  • 1F-xRi: flexible solder-mask (partial) 
  • xRi-2F-xRi: cover layer (polyimide/adhesive) 

Generally, all IPC-2223A Class A (flex-to-install) designs are possible.
