INDIUM NC-SMQ92H
Harmonization Code : 3208.20.90 | Paints and varnishes that are dispersed or dissolved in a non aqueous medium
Main features
- Consistent Fine-Pitch Deposition
- Extended Stencil and Tack Life
- Low-Spatter Halogen-Free Reflow
Product Description
Indium NC-SMQ92H No-Clean Solder Paste is a halogen-free, air-reflow solder paste formulated for fine-pitch deposition with low flux spatter. It combines consistent printing, more than 12 hours of stencil life under the stated conditions, and a hard, clear residue after reflow. The ROL0 flux system shows typical tackiness of 32 g and a typical viscosity of 1,400 poise for the specified Sn63 Type 3 configuration. NC-SMQ92H is supplied for both stencil printing and dispensing formats and can be processed in air or nitrogen. Applications include fine-pitch SMT printing, dispensing, and reflow using supported SnPb alloy configurations.
Key features
- Fine-Pitch Deposition: Consistent printing and a minimum 1.5 aperture aspect ratio support fine-feature stencil release.
- Extended Stencil Life: Stencil life exceeds 12 hours at 22 to 28 deg C and 30 to 60% RH.
- Low-Spatter No-Clean Flux: Halogen-free ROL0 flux is formulated for low spatter and air reflow.
Applications / Suitable for
- Fine-pitch SMT printing
- Solder paste dispensing
- SnPb air or nitrogen reflow
