Machine Capability Analysis (MCA) testing helps improve yields and reduce soldering and missing-component defects by improving dispense accuracy. By running a capability test, the basic settings and functions of the dispenser are checked (clamping, sensors, nozzles, camera, robot, etc.) so that the dispenser is once again operating within the manufacturer’s specifications.

Machine capability for an automated dispenser of adhesives or solder pastes is measured by dispensing dots of material onto a patterned glass test plate and then evaluating it in CeTaQ’s CmController5, which measures the positional accuracy of the dots. The glass plate minimizes the dimensional errors associated with an FR-4 board, for accurate, relevant measurements.

The controller measures the positioning accuracy (x,y) of the dispense gantry, and evaluates deposit accuracy as well as diameter consistency. Measurements are calculated, taking into consideration the impact of placement order, type of head, single dot versus double dot, needle configuration and other parameters.

Provides measurement technology for equipment and process capability analysis for dispensers and other production equipment; the data and measurement results obtained provide the base for stable and controlled dispensing and processing. Special vision algorithms, accurate glass plates and components allow for independent measurement of Cp and Cpk indices on production equipment. All brands and models of SMT printers, dispensers, placement and semiconductor machines are validated. Certification reports validate performance. Does not require a controlled cleanroom environment.
