Meteorwave 1000NF

High Speed / Very Low Loss No Flow Prepreg
Part Number: Meteorwave 1000 P

Nelco Meteorwave® 1000NF (“no flow”) is based on the Meteorwave 1000 resin system. It is a high speed/very low loss digital electronic material offering very advanced electrical performance and very high reliability. Meteorwave 1000NF prepreg is designed for bonding flex circuitry and bonding heat sinks to rigid circuit boards. This prepreg adheres well to most substrates. It’s minimal and consistent, flow is controlled through precise rheological and prepreg process control. Meteorwave 1000NF prepreg is designed for multiple high temperature lead-free assemblies and high layer count printed circuit board designs which require very high levels of reliability.
