Main features
- PTFE filled
- No bleed
- Lower modulus than QMI536NB
Product Description
LOCTITE ABLESTIK QMI538NB is a PTFE filled non-conductive die attach paste designed for applications which require very low stress and robust mechanical properties. This low modulus (100MPa) product is used for MEMS and die stacking, with NB standing for No Bleed.
LOCTITE ABLESTIK QMI538NB is a hydrophobic BMI Hybrid product that offers low viscosity and reduced resin bleed, along with stability at higher temperatures. With its excellent adhesive strength and good popcorning resistance after solder reflow temperatures it is typically used on solder resist, flexible tapes and on bare siliconE and die passivation.
