Multi-Seals has released Nano-forms epoxy preforms to provide precision seals on microelectronics. The preforms have an outside diameter of 0.035inch and an inside diameter of 0.011inch. They allow repeatable placement of minute amounts of epoxy with high precision. The preforms' dimensional tolerances are as close as ±0.0005inch for critical applications. They can control epoxy volume to within 0.00002cc for a typical configuration.
The repeatability is also promoted with closely controlled pre-mixed ratios of resin to catalyst. The preforms are not affected by pot life, hence the epoxy viscosity is consistent from beginning to the end of production batch. They are suitable for sealing fiber-optics and subminiature switches, capacitors, diodes, and LEDs. The epoxy preforms are pre-shaped, and when heated they melt and cure to form a consistent seal that protects components from dust, moisture, oil, flux, solvents, and conformal coatings.
