Model 3500-II Automatic Component Assembly Cell

The Model 3500-II is designed for fully automatic, high speed, precision microelectronics assembly. The flexible, computer controlled workcell performs adhesive dispense, component placement and flip chip operations over a spacious 700 sq.in. work area. The machine base, a honeycomb core optical table, provides vibration damping and thermal settling response superior to granite.

Submicron axis resolution yields typical placement accuracies of ±0.5 mil (12.7 µm). The cantilever design permits unobstructed, open access on three sides for setup, and an infrared light curtain ensures operator safety during production. Soft touchdown, or non-contact laser height sensing mechanisms assist in precise pickup and placement of fragile devices such as GaAs. An 8-position, bi-directional turret head can rapidly change tools on the fly without a space-consuming tool dock.

An advanced Cognex gray-scale pattern recognition system locates randomly oriented device features under a wide variety of background conditions and lighting. The PR system includes auto focus and programmable magnification and light intensity.

Operating in a true Microsoft® Windows™-based environment, the Model 3500-ll brings unparalleled software versatility, power and ease of use to microelectronics assembly. The graphical, user-friendly interface assists in bonding setup, operation, diagnostics, and calibration.

Model 3500-ll options include equipment for fully automatic substrate handling: input, preheat, eutectic heating stage, cool down and transfer. Many other options are available to meet special application requirements for custom cells and in-line systems:
