Excel Precision Company Profile
Excel Precision Corporation is a leading designer,
manufacturer and marketer of precision measurement
systems. The company's systems include interferometers
and optical sensors to provide measurement solutions
for its customers. Headquartered in Santa Clara,
California, Excel has 3 foreign sales offices
Excel has demonstrated its ability to innovate
by bringing the following products to market:
" High speed interferometer for DRAM manufacturing,
" Innovative technique for absolute metrology
" Laser-guided servowriting device for
high capacity hard disk drive,
" Weather station for air turbulence measurement
" System for simultaneous calibration of
all axes of a machine tool or CMM.
Excel is headed by President John Tsai who has
led the company from its founding in 1986. Dr
Tsai has focused Excel Precision's resources
on meeting key customer needs for precision
measurement solutions by using innovative technology.
The business breaks into the 3 key areas of
Semiconductor, manufacturing, and hard drive
The semiconductor market consists of equipment
to precisely measure the position of a stage
often holding a wafer in some stage of processing.
Excel Precision has become expert at providing
extreme precision and measuring speeds for fast
throughput and high yields in this market. Excel
Precision also markets its interferometer-based
systems for Scanning Electron Microscopes that
are often used in the semiconductor market.
Excel has long provided calibration equipment
used to optimize CNC machines and Coordinate
Measuring Machines (CMM). While extremely accurate,
these calibration kits require hours of valuable
machine time to complete the calibration. Excel
Precision's latest technology called 6 DOF will
measure all critical machine parameters in only
two passes with only one simple setup. The resulting
increase in machine "up time" and
in accuracy due to a better understanding of
the measurement interactions promise to be dramatic.
Computer hard drive
Excel has invented and patented a non-contact
laser technique that "writes" the
tracks on a computer hard disk. This technique
increases the storage density and improves manufacturing
yield compared to existing mechanical techniques.
