Abstract:
A device and method for manufacturing integrated circuit packaging using a mold plunger with position compensation in a manufacturing setting. In an embodiment, a compensating mold plunger, which may be used during the manufacture of an integrated circuit package, engages a die set on a carrier and within a bushing. This may be done to inject a mold compound on top of the die/carrier. If the bushing that is housing the die/carrier tandem is misaligned with the plunger in any lateral direction, the amount of pressure may be compromised. A compensating mold plunger includes a flexible portion that allows for the head of the plunger to properly engage the die/carrier despite any possible misalignments. Further, different die/carrier combinations may also be used with a compensating mold plunger because the pressure and force applied may be uniform inside a bushing despite the contents of the bushing.
