Plate circuitry onto new laser-activated PBT.Degussa AG's High Performance Polymers group in Germany has been licensed to use a special laser-activated additive additive In foods, any of various chemical substances added to produce desirable effects. Additives include such substances as artificial or natural colourings and flavourings; stabilizers, emulsifiers, and thickeners; preservatives and humectants (moisture-retainers); and that allows direct electroplating electroplating: see plating. electroplating Process of coating with metal by means of an electric current. Plating metal may be transferred to conductive surfaces (e.g., metals) or to nonconductive surfaces (e.g. of electrical circuitry onto PBT PBT Provider Backbone Transport (networking technology adding determinism to ethernet) PBT Polybutylene Terephthalate PBT Profit Before Tax PBT Paper Based Test (education) . This process permits making 3D molded interconnect devices (MIDs) with circuits selectively plated on their surfaces. Degussa (U.S. office is Degussa Corp. in Parsippany, N.J.) is using the laser-activated additive in its Vestodur CL radiation-crosslinkable PBT compounds formulated for short-term resistance to temperatures of up to 400 C (750 F) for reflow soldering Reflow soldering is the most common means to attach a surface mounted component to a circuit board, and typically consists of applying solder paste, positioning the devices, and reflowing the solder in a conveyorized oven. of electronic components. With the additive technology from German laser supplier LPKF Laser & Electronics AG, producers of MIDs can eliminate production steps and cut cost. A moving laser beam is used to trace the paths of highdensity circuitry on the molded part. Where the laser beam activates the additive, the PBT becomes electroplatable.
