IGBT modules are the pressure contact ones without base plates.
Peak pressure, contact area and force time integral were measured using the Pedar insole system.
The objective is to assess the four methods based on calculated contact pressure, contact patch size and penetration depth.
The effects of temperature, pressure, contact time and feed conditions are examined.
The contact pressure, contact region and indentation are calculated for various indenters by solving the equations numerically.
A closed-form membrane analysis with Hertz-type contact is developed to describe the relationship between pressure, contact radius and contact force.
The advanced pressure contact design eliminates the base plate together with the base plate solder and the terminal solder interconnections and thus enhances the thermal cycling capability.
A closed-form membrane analysis is developed for the JKR, DMT and Maugis regimes, which describes the relationships between adhesion energy, pressure, contact radius and contact force.
A new model is presented of a cellulosic cylinder which thermally degrades, because of a high pressure contact of its bottom side against a hot spinning disk.
The measurement of SC-240 Tanita is based on the pressure contact on the footpad electrodes with a single frequency of 50 60 kHz.
