Thermal Test Chip

The thermal test chip a 2.5 x 2.5mm silicon semiconductor die enclosed in a 15.24 x 31.5mm ceramic 24 pin DIP package. DIP packages have 0.10” (2.54mm) pin pitch. The die contains several heat generating elements including two deposited metal film resistors and four diodes. Small amounts of power can be applied to one or more of the resistors or diodes resulting in temperature increases on each element of fractions of a degree. The thermal test chip can be very useful when training system users to perform tests such as Lock-in Thermography.
