Deformable Conductive Bondline Spacers – Silver-Coated PMMA Microspheres
What are deformable conductive bondline spacers? Deformable conductive bondline spacers are ideal when some deflection of the particles is preferred while maintaining conductivity and compliance. Poly(methyl methacrylate), also known as PMMA or acrylic, micropshere cores can be combined with a conductive silver coating to create deformable conductive bondline spacers. Deformable conductive spacers offer benefits for Ansiotropic Conductive Film (ACF)…
Microspheres as Bond Line Spacers in Epoxies
Spacer Grade Glass Microspheres are presently used in gas plasma displays, automotive mirrors, electronic displays, flip chip technology, filters, sporting goods equipment, calibration standards and transformer manufacturing. Every day engineers are finding new and innovative uses for bond line spacers.
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…
