Mechanical Reliability Evaluation System

By anticipating changes in the market trends, a new evaluation method was developed.

The products which require quality reliability evaluation are evolving daily due to the popularization of portable equipment, improvement of connection technologies which connects units, and advancement of LSI packages such as LGA and connection technologies. In order to anticipate changes in technologies and the market trends quickly and to provide the best solutions to our customers, ETAC strives to develop new evaluation methods, systems (products), and related software.

Development of new "mechanical reliability evaluation method" and its commercialization
ETAC developed a new mechanical reliability evaluation system which differs from our traditional reliability evaluation systems that apply environmental load factors, and commercialized it.
The mechanical reliability evaluation method allows testing under close-to-actual usage conditions, and the data can be collected in a short time.

Repeated Bending Reliability Evaluation System "RBS 01" and "RBS 06"

This evaluation system monitors the electrical resistance behavior while a fixed bending load is repeatedly applied to the PCBA that is used for mobile phones and other devices. Two models, RBS 01 for 1 channel specification and RBS 06 for 6 channel specifications are available.

Basic Functions
  • By entering assumed displacement (mm), the displacement which corresponds to the target distortion rate can be obtained.
  • By entering the maximum and minimum displacement values gained from the above displacement, the distortion/displacement curve can be obtained.
  • Based on the distortion/displacement curve, the desired displacement amount (mm) is entered for the bending cycle test. The displacement/life curve can be obtained through tests using any displacement amount (mm).
Main Applications
  • Mobile phones PCBA
  • LGA package
  • Circuit board for PCs, etc.

Basic Functions
  • Test force (Max./Min.), displacement (Max./Min.), energy (connection/disconnection), hysteresis, and contact resistance (at connection) can be measured.
  • Two types of measurement modes are available.
    Measurement mode 1: Measured at every connection/disconnection starting point and halfway mark for every cycle.
    Measurement mode 2: Measured at every connection/disconnection starting point and halfway mark for every cycle.
  • Measured contact resistant values are compared with the absolute value and relative value.
Main Applications
  • Various connectors
  • Various sockets
  • Durability tests for plated parts of terminals
