Reduced Sub-Surface Damage
Strasbaugh's innovative nTellect Grinder incorporates near-frictionless, force-sensitive infeed mechanics with an intelligent control system. Rather than force-feeding the grinding wheels at fixed feed rates, nTellect's force adaptive, infeed system design allows the grinding wheel dynamics to determine the precise stock removal rate. This increases wafer strength and reduces wafer breakage.

Improved Surface Finish
nTellect's ultra-stiff air bearing spindles, sub-micron feed rates and rigid tool construction make mirror finishes possible. Combine this with Strasbaugh's complete selection of advanced diamond wheels, and users can achieve the surface finish required for their specific process.

Repeatable Thickness Control
nTellect's in-situ digital measurement probes provide real time thickness measurements to the intelligent control system. The effects of thermal expansion and diamond wheel wear are eliminated, thus ensuring accurate, consistent wafer thicknesses, which eliminates costly re-work.

Linear Traversing Grind Spindles
The unique linear traversing grind spindles alternate between coarse grinding, dual grinding, and fine grinding. The grind spindles move on precise, preloaded roller bearings that provide smooth, rapid motion. The wafer remains on the same work spindle during grinding to reduce wafer handling and optimize throughput.

State-of-the-Art Technologies
nTellect is now offered with two new technologies: Tapeless Backgrinding and ultra-fine grit grind wheels. Tapeless Backgrinding eliminates the need for tape and dramatically reduces grinding costs. The ultra-fine grit grind wheels enhance die strength and improve surface finish, making them well-suited for the most demanding thin wafer applications.

Select Coat® SL-940E

Powerful Process Control for Conformal Coating

Asymtek’s Select Coat® 940 Series conformal coating system is designed to provide the highest quality and productivity for automated coating processes.
The SL-940E is a high-speed, high-accuracy coating system with integrated, closed-loop process control that ensures superior coating quality. Process parameters are recorded and traceable through Easy Coat® (ECXP) software running on Windows® XP operating system.
Fluid and air pressure are set and monitored through software-controlled electronic regulators. A complete process history can be maintained in ECXP log files for these critical parameters.
A wide range of process parameters can be monitored for statistical process control, including Asymtek’s Laser Fan Width Control, Viscosity Control System, Bar Code System, and Flow Monitoring. The processes are automatically maintained within limits and process status is logged for traceability. This information can be exchanged with customer-specific Factory Information Systems (FIS).


ECXP software, together with an optional vision system, makes teaching your coating program much easier. Pattern recognition software is also available.
Productivity is maximized with ECXP software and machine design. The SL-940E system operates at 1g peak accelerations, is capable of velocities of 1 meter per second, and can accommodate product sizes up to 500 mm.
The SL-940E system has been independently tested and certified for compliance with relevant safety standards including CE and SEMI.
