Deformable Conductive Bondline Spacers – Silver-Coated PMMA Microspheres

PMPMS AG 1 5 125 150um Deformable Conductive Bondline Spacers - Silver-Coated PMMA Microspheres

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 required. In these circumstances…

Advantages of Borosilicate Glass Microspheres in 0.03mm to 0.2mm sizing

Borosilicate glass offers advantages over standard soda lime glass microbeads.

  • Roundness is >90% (Soda lime >85%)
  • Density is the lowest of most glasses at 2.2g/cc (Soda Lime 2.5g/cc)
  • Very low thermal expansion coefficient 32×10-7/?C (for 30-300?C) (Soda Lime: 90×10-7/?C)

The high roundness, and low thermal expansion make…
