What are bondline spacers? Microspheres are widely used as bond line spacers because today’s technological advancements are demanding tighter and tighter tolerances. Assembly of many instruments, especially in electronics, optics, biotechnology, calibration, and medical devices, requires holding precise spacing between parts. Depending on the requirements of the application, a rigid non-flexible bond line may be … Read more
Electrically conductive microspheres are produced by applying a metallic silver coating to the surface of the microspheres, thus giving the advantages of a metal particle with the additional properties of the core microsphere. Typically hollow glass microspheres are silver coated as this offers the combination of a low density filler and a conductive particle. Coatings with EMI shielding of greater than 45db have been produced by adding as little as 20% by weight of M-18 silver coated microspheres.
