Deformable Conductive Bondline Spacers – Silver-Coated PMMA Microspheres

PMPMS AG 1 5 125 150um 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)…

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…

Monodisperse – Spacer Grade Microspheres

Scientists are constantly looking for narrower particle size distributions (monodispersed) of microspheres to help increase the consistency and correlation between theoretical models and verification experiments.? In an effort to fill the increasing demand for these particles Cospheric has launched a new line of spacer grade microspheres. Monodisperse microspheres are currently offered in diameters of:?? 21-24um, 23-26um, 25-28um, 27-30um, 29-32um,…

Technical Properties of PMMA Microspheres

PMMA Microspheres - Technical Specifications

In this article we will discuss the applications and technical properties of PMMA microspheres. What are PMMA Microspheres? PMMA micropsheres are also known as Poly(methyl methacrylate) or acrylic microspheres. PMMA, an ester of methacrylic acid (CH2=CCO2H), is a synthetic resin produced from the polymerization of methyl methacrylate. Ever since PMMA resin was discovered and first commercialized in 1930s, it…
