The creation of integrated circuitry on plastic can be accomplished through several different processes. The two main processes are 2-shot injection molding and Laser Direct Structuring (LDS).

  • The creation of a 2-shot injection mold can be very expensive and once the mold is created, your circuitry pattern is set. Should you later decide to change the circuit pattern, a new mold must be created. It is imperative that you prototype and set your circuit pattern prior to creating your mold.
  • LDS can be used as a prototyping tool for your high volume 2-shot component. Parts can be made via a fused deposition process (3D printing). Furthermore, circuitry can be designed and tested prior to the creation of the mold.This saves both time and money.

The biggest advantage of LDS over 2-shot is the separation of the processes. In 2-shot molding, the electrical design is tied to the mold itself. Once the mold is done you can’t change anything unless you change to a different mold. However with LDS, the standard molding of the part doesn’t impact the circuit structure. LDS allows you to move the design phase of the electrical to much later in the process, thereby providing the opportunity to fine tune the part.

Furthermore, you LDS mitigates potential problems or tolerances in the molding that could not be anticipated at the start. The electrical design can be adjusted to meet mechanical requirements and compensate for unforeseen issues.

SelectConnect Technologies manufactures 3-dimensional molded interconnects using the LPKF-LDS process to laser scribe circuitry on injection molded components, as well as selectively plates circuits integrated into components produced by the 2-shot injection molding process. We are the only contract provider of LDS 3D-MID services in North America and work on projects from early phase prototypes and scale up to high-volume production. Learn more.
