Electronic Inspection Systems
Intego's knowhow even makes it possible to identify challenging defects that may be located under the surface. One system is the inspection of chips by means of lock-in thermography, which visually represents the IR radiation intensity signal of electronics. Special lasers and flash lamps generate a very short heat impulse (10 ms) on the chip, which generates a measurable heat flow. In most cases, a resolution of < 1 μm can be achieved.
