Atomic layer deposition (ALD) is a process of creating coatings on a molecular layer by layer basis. Using an iterated sequence of self-saturating deposition cycles that are self-terminating, a single layer can be deposited at a time, allowing for highly uniform films with complete conformality. The composition of the film typically used for coating printed wiring boards (PWBs) is a high alumina (Al2O3) sequential deposition of alumina and titania capped with a corrosion protective titanium aluminate layer, most notably ALD-Cap from Sundew Technologies, LLC. Rework is a process of restoring an electronics assembly to full functionality to prolong equipment life and reduce the amount of scrap. The process typically involves:

Is it possible to coat electronic assemblies with a thin, uniform in thickness, pinhole-free, moisture impervious, truly hermetic (by the MIL-STD-883 definition) film of ceramic material that is far more affordable than placing the same electronic assemblies in the currently used glass-to-metal sealed, thick, heavy, metal-and-ceramic-based hermetic enclosures? Since the coating (called a “conformal coating”) would be both hermetic (moisture proof) and hundreds or thousands of times thinner than the currently used enclosures, it would be both less expensive, lighter, and still just as effective in excluding moisture (hermetic) as the current heavy, bulky, expensive electronic enclosures are.

Conformal coatings are applied to Printed Circuit Board Assemblies(PCBAs) using a variety of different methods. There are six main methods of applying conformal coatings: manual spraying, automated spraying, dipping, brushing, selective coating, and vacuum deposition.

Solder paste dispensing is usually considered a slow process. Due to the speed advantages, screen printing is used to apply solder paste whenever possible. However, screen printing is not always an option. Leveraging the high speed of piezo drive technology opens the door to a broad range of solder paste dispensing applications. The ability to dispense dots under 300-μm diameter, even as small as 125 μm, enables BGA rework, small geometry deposits for miniaturized passive components, electrical connections in recessed cavities, and RF shield attach for handheld devices.

Nordson ASYMTEK introduces the new Helios™ SD-960 Series Automated Dispensing System for medium and bulk volume deposits of single- (1K) and two-component (2K) materials in electronics manufacturing and printed circuit board assembly. The Helios system is ideal to deposit volumes greater than 1cc, and line widths and dots that exceed 1mm, but it can deposit volumes down to 0.3cc and line widths as narrow as 0.3mm. The system supports highly abrasive thermal interface materials (TIM), silicones, epoxies, and grease for applications such as potting, sealing, gasketing, and structural adhesives.
