Microphone IC COB
DESCRIPTION
BESIL 9442 Semiconductor Protective Coating are high purity, one-part,solventless silicone elastomers. They provide excellent self-priming adhesion to most device surfaces resulting in high-voltage isolation and moisture protection. These materials cure to a medium durometer elastomer in applications where a dry, non-tacky surface is desired.BESIL 9442 is black in thin and thick films.
FEATURES
Significant features of BESIL 9442 include:
• High purity
• Excellent self-priming adhesion to common electronic device and circuit
substrates with superior moisture resistance
• Flexibility at high and low temperatures
• Excellent electrical properties over a wide operating temperature range
• Protection from moisture, dirt and other atmospheric contaminants
• Blockage for light-sensitive devices
