Laminating Precision Parts

When a dielectric is required to maintain accurate finger spacing or for insulation, Tech-Etch, Plymouth, PA, can laminate materials such as polyimide. Polyimide can be die-cut and directly bonded in place or full sheet laminated and then photo etched for extremely accurate positioning. Parts can be formed after lamination of insulation. The company also photo etches polyimide film into flat parts including nonconductive washers, screens, gaskets, insulation layers, and liners, as well as haptics for intraocular lenses used in cataract surgery. For flexible circuits, the coverlay is the insulating layer of polyimide placed over the exposed conductors.

Wire Coating

Raumedic, Hembrects, Germany, has developed a wire coating process that produces a complete, even, and highly durable surface that can be made up of a range of polymeric materials. Under controlled clean room conditions, the VariCoat® process extrudes the melted polymer directly onto the wire, braid, or fiber in cutting-edge microextrusion technology. In this single-step process, the coating and the substrate are subjected to strain just once. The process produces a homogeneous pin-hole-free layer and extremely smooth surface structures. Features include concentric coating of the substrate, uniform layer thicknesses, no material flaking, and a customized degree of bond strength.

Light Engine

Lumencor, Beaverton, OR, offers new light engines that produce powerful outputs based on an array of solid state light sources. The SOLA SE UV-nlR and SOLA SE V-nIR light engines turn on and off in unison producing white light that replicates the spectral output traditionally obtained from mercury lamps. The UV output centers on 365 nm and the violet (V) centers on 395 nm. They each efficiently excite nuclear dyes like DAPI and Hoechst. At the other end of the spectrum, a near infrared source at ~735 nm now excites Cy7 and ICG. The 500–600 nm output of the SOLA light engine, obtained from the application of the company's proprietary light pipe technology, excites fluors in the visible (VIS) spectral region such as mCherry, TRITC, and Texas Red.
