Measuring Wedge bond & Ball bond

HC-AZ is a visual measurement/inspection device which has X, Y, and Z axes. It can measure wedge/ball bond width automatically and measure loop height semiautomatically. It can store statistics data and screenshots automatically that used to be performed manually (Manual measurement / writing down measurement data / PC data entry) so that this device will set you free from daunting tasks.

Bond width auto-measurement

HC-AZ measures bond width automatically with automatic image processing system at the programmed measuring locations. It can execute nonstop measurement for all programmed locations as well as one-by-one measurement that enables an operator to conduct quality check at every single measurement point. You can reconfirm measurement results and re-measure bond width after all auto-measurements.

Loop height semi-auto-measurement

HC-AZ measures loop height way faster than manual measurement. The XY table moves to programmed measuring locations then focuses on bottom surface positions and loop top positions automatically. An operator decides whether he/she executes loop height measurement or makes fine focus adjustments due to height variation. The fine focus adjustment is done by using the trackball. The linear scale is mounted on Z lens axis for accurate focusing.

Statistics data and Screenshots

Measurement results and measurement screenshots can be sorted and stored by date or measurement locations. Measurement data is graphed automatically so that measurement results can be easily confirmed. Measurement data can be exported in csv files.

Measurement result output

Bond width auto-measurement data and loop height semi-measurement data can be exported in csv files so that this function is very useful to summarize measurement results. Users can output measurement data by measurement date and specific measurement locations.

Why HC-AZ?

Measurement time reduction

Highly sophisticated HC-AZ saves tremendous amount of time for quality check. It also eliminates measurement result variation that is caused by operators.

Example 1:Bond width measurement time in comparison

測定時間の短縮

  • Product A:29 wires
  • Number of measurement locations:58

Over 60% reduction in test duration!

Example 2:Loop height measurement time in comparison

測定時間の短縮②

  • Product A:29 wires
  • Number of measurement locations:29

Over 30% reduction in test duration!

Measurement stabilization

Each operator’s bond width measurement results vary. Even the same operator measures the same bond width, measurement result is not always the same. HC-AZ eliminates measurement errors remarkably but achieves stable measurement results at every single measurement.

Various user-friendly functions

Mapping system

The mapping system shows which area is being displayed on video screen when a program is being edited and actual measurement is being performed. The camera will move to the position where you click on the position in the map.
