Chip Encapsulant endures bending and flexing at -20°C.

Press Release Summary:




DYMAX 9008 chip encapsulant forms transparent layer that protects components and leads from moisture, dust, and other contaminants. Coating cures in 10-30 seconds under 200-1,200 mW/cm² intensity lights, enabling thicknesses to 1.5 mm to cure in UV conveyor belts at speeds of 2-4 ft/min. Cure depths to ¼ in. are possible. Coating adheres to variety of surfaces including glass-filled epoxy, metal and ceramic surfaces, as well as polyimide and other flex materials.



Original Press Release:



New UV Chip Encapsulant 9008 Passes Polyimide Bend Test; Even at -20°C



Curing in seconds upon exposure to UV/visible light, DYMAX 9008 chip encapsulant exhibits excellent adhesion to polyimide and endures bending and flexing even at extremes of thermal cycling to -20ºC. The cured coating forms a transparent layer, which protects components and leads from moisture, dust and other contaminants. DYMAX 9008 is formulated to dispense consistently through precision dispensing systems. Controlled placement optimizes the process and minimizes resin consumption. The flow characteristics of DYMAX 9008 are designed to assure coverage of leads of even large surface mount components, without running to areas where protection is not needed.

9008 flexible coating cures in 10 to 30 seconds under standard longwave, moderate or high intensity lights (200 - 1200 mW/cm²). The length of exposure depends upon the light used and thickness of the coating. However, thicknesses to 60 mils (1.5mm) can be cured in UV conveyor belts at speeds of 2 to 4 feet per minute or under spot lamps in a few seconds. Cure depths to ¼" are possible.

Like other DYMAX coatings, 9008 is a tough, durable resin with excellent electrical properties. It has high ionic purity as well as the ability to withstand harsh environmental conditions. Coatings form protective surfaces and exhibit adhesion to a wide variety of surfaces including glass-filled epoxy, metal and ceramic surfaces as well as polyimide and other flex materials. Because 9008 is highly flexible, even at very low temperatures, the encapsulant provides superior protection where rugged conditions are the rule.
