Deformable Silver Coated PMMA Microsphere Spacers

PMPMS AG 1 5 125 150um 480x480 Deformable Silver Coated PMMA Microsphere Spacers

Silver Coated Glass Microspheres work well for increasing the conductivity of bond lines, but they lack the capability to deform when compressed to give increased conductive contact between the surfaces of the bond line.? These newly released Silver Coated PMMA Microspheres offer the low weight deformable pmma cores, and 250nm thick silver coating for high conductivity. Conductivity of this…

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…
