Embossed carrier cover tape is pulled to measure its peel (bonding) strength for quality evaluation. It enables testing according to the corresponding part of IEC and JIS standard.

In this video, operating point of tactile switch is detected by the mark-on function of our force-displacement test unit. By using a customized cable, force and displacement values at the operating point of the switch are automatically recorded and shown on the graph drawn by our data graphing software.

Operating force of a switch is measured with a manual test stand in this video. This type of measurement is also called switch feeling test and describes easiness of pressing switches or click feeling in numerical values. By setting Peak Drops(decreasing values) on the force gauge, the force at the moment when the switch gets on is recorded as the first peak value. Displacement value to turn the switch on can be measured using the test stand with displacement input function.

IMADA's force-displacement tester determines click sensation (feeling) of tactile switches. In the video, the tester presses a switch, measuring the resistance force and graphing the measurement. In other words, to determine the click sensation, you need to measure displacement as well as force. Then, the tester graphs force transition with reference to displacement, helping identify the hysteresis (zero reversion). Thus, the force-displacement tester handles various characteristic evaluation other than click sensation of switches. The remarkable thing is that the tester automatically detects contact point of the sample and presses switches by pre-set displacement, which improves repeatability and test-efficiency.
