Dispenser for contamination-sensitive applications

S-920N-C certified for Class 100 cleanroom use

The S-920N-C stainless steel dispensing system from Nordson Asymtek, a US supplier of dispensing, coating and jetting technologies, is certified for Class 100 cleanroom use. It is for applications that are sensitive to contamination by submicron-sized particles, such as wafer-level packaging and disk drive assembly. Film-frame or bare-wafer handling can be added for integrated material loading and unloading.

The S-920N-C system's stainless steel enclosure has a passivated finish for easy wipe-down. Its high-flex electrical cables are enclosed in a cleanroom-certified jacket that reduces particulation and outgassing. The HEPA filter provides a downward particle-free air column within the dispense area, and the machine interior is positively pressurised. All pneumatic valves are exhausted to a duct for connection to a house vacuum to avoid particle emissions into the cleanroom.

The S-920N-C features technologically advanced and integrated software and hardware control to reduce process variation, increase yield, and reduce cost. Calibrated Process Jetting (CPJ) automatically maintains volumetric repeatability during long production runs, while Controlled Process Heat (CpH) adds recipe-controlled heat management for improved thermal efficiency with faster temperature increase.

A digital vision system with dual-colour, adjustable on-axis lighting offers fast and reliable image acquisition for increased throughput. Adding the Fids-on-the-Fly option accelerates fiducial capture, and laser height sensing further reduces time spent on non-dispense routines.

The scalable S-920N-C can be configured with single or dual lanes and up to six heat stations with the dual lane configuration.

Headquartered in Westlake, Ohio, Nordson has direct operations and sales support offices in more than 30 countries.
