Press-fit monitoring:
a common operation, an uncommon approach

Pressing or joining is one of the most common manufacturing operations. Press-fit monitors (also called force-distance, assembly press or load cell monitors) measure force versus time, force versus distance and distance versus time to determine whether the process met the set standards.

Because pressing is such a common application, some manufacturers believe that only the most basic systems are required to monitor it. Though these may appear to perform the function on the line, they also have their limitations, as any process engineer with a quality spill or yield target to meet will tell you. These simple systems don’t provide enough information to help a manufacturer take action, whether it’s to optimize test limits to get yield up or to find out why a problem occurred. The limited measurement also means minor defects can be missed at the station but found later downstream when the costs of dealing with them becomes much more significant.

Sciemetric’s competitively priced sigPOD Press solution uses signature analysis to capture, analyze and store all of the data points of the pressing operation. Having the signatures provides distinct advantages: greater test accuracy, the ability to create a range of visual reports, and the built-in ability to dynamically set and manage the test limits.

See some examples of press-fitting and joining in the application notes or review the sigPOD Press datasheet.
