Large Component/Wafer Scale Assembly

Customers in sensor production, medical technologies, automotive, etc. are frequently presented with the challenge to introduce high-accuracy assembly processes for large components or wafers.

Panels with sizes up to 6" x 8" (ie. IR sensors, TFT flat panel detectors, nanofluid flow chambers, micro fluid systems, parallel-plate flow chambers, micro reactors, color and multispectral filters, etc.) require assembly equipment with a specific set of skills. The same holds true for components which are bonded at wafer level in order to optimize process times and decrease average cost per unit (i.e. micro optics, wafer-scale CCD and CMOS, stacked memory, 3D packages, etc.).

A viable equipment solution should provide a post-bond accuracy of 3 µm or better. This is achieved by combining a high-resolution vision alignment system, large substrate heating options with uniform heat distribution, elevated bonding forces for high bump count, a reliable coplanarity control and the ability to integrate multi point alignment for components exceeding the field of view.
