LPKF ProtoPaint LDS

LDS Coating of 3D-Molded Interconnect Devices

You are here: Products > Rapid PCB Prototyping > LDS Prototyping > ProtoPaint LDS
 
Description
The laser direct structuring (LDS) process is well known as a key factor in the production of smartphone and tablet antennas, but it is also becoming a significant player in LED lighting and the automotive arena. Now with LPKF ProtoPaint LDS, a new paint is available that turns a variety of spatial base bodies into three-dimensional molded interconnect devices.

Strip Conductors from a Spray Can

In series production, a non-machined part is used that is made from a plastic provided with an LDS additive in single-component injection molding. LPKF ProtoPaint LDS is an easy-to-apply paint that produces a functional coating, even without expensive injection molding tools. The LDS process then creates the structures on the paint coat.

LDS Prototypes in One Day
ProtoPaint LDS enables users to quickly and inexpensively create 3D-molded interconnect device prototypes. The components created can be structured with the laser, like conventional LDS components. Electronic components can be applied by means of conductive adhesives for assembled prototypes.
