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…
Calculating microspheres per gram
During scientific experiment design and analysis it is common to need to know the number of spheres per gram of dry material. We have put together the table below to help speed up the process.
Monodisperse Silica Nanospheres and Microspheres – Dry Powder
Silica nanoparticles and nanospheres are now available in distributions of less than 10% CV in the sizes of 0.25 micron, 0.5micron, 0.75 micron, 1.0 micron, 4 micron and 8 micron.
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…
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
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…
