SMALLER, FASTER, CHEAPER

Using Surface Mount Technology to Reduce Size and Cost

EyeSys Vision was interested in reducing the size, cost, and complexity of an instrument for corneal topography that they were producing and marketing. The device had multiple frame grabbers, PC interface circuitry, and VGA image generation circuitry built into a passive PC backplane with multiple cables. Indus helped redesign and repackage all the electronics for the device into a single board.

Shown to the left is a six layer circuit board that makes extensive use of surface mount technology and programmable gate array logic. This board replaced the entire passive backplane assembly, reduced cabling and space requirements and offered better functionality than the earlier device. The manufacturing costs in electronics subassemblies alone dropped from $1200 down to $500.

The final product has been in production for several years and is sold as the Eyesys/Premier System2000. Indus has also assisted Premier Laser with OEM supply of the boards.
