Dip was the first microelectronic package to support the plastic body and it was the top choice for packaging in the industry for many years 43 44 an example of a dip can be seen in fig. Including plastic surface mount packages hermetic packages and advanced designs such as flip chip chip on board and multi chip models. The thermal resistance of an ic package is the measure of the package s ability to transfer heat generated by the ic die to the circuit board or the ambient.

Integrated circuit packaging overview. Ic or integrated circuit packaging refers literally to the material that contains a semiconductor device. For plastic and ceramic materials refer to. In calculations thermal resistance is identified as theta derived from the greek word for heat thermos it is thermal resistance that particularly interests us.

The earliest integrated circuits were packaged in ceramic flat packs which the military used for many years for their reliability and small size. The package is a case that surrounds the circuit material to protect it from corrosion or physical damage and to allow for mounting of the electrical contacts connecting it to the pcb. List of common integrated circuit packagesthe data in table 1 list the typical range of junction to ambient thermal resistance θ ja observed for some common integrated circuit packages as a method of comparing and describing the thermal performance of the packages the standard thermal resistances as defined by jedec are used 1. Integrated circuit packaging and thermal design danilo manstretta microlab unipv it.

May 25 2016 anysilicon. An insulating packaging such as ceramic or plastic allows this insulation and protection while permitting heat dissipation through controlled paths such as integrated heat sinks or heat sink tabs in some packages or just through the pins in others. Ceramic plate test cpt for evaluating the solderability of ic devices. An integrated circuit package has the sole purpose of protecting and maintaining one or more integrated circuits.

The integrated circuit packaging process. What started as a simple means of housing semiconductor components has evolved to the point where packaging is used as a way to improve the performance of end devices. The other type of packaging used in the 1970s called the icp integrated circuit package was the ceramic package sometime round as the transistor package with the conductors on one side co axially with the package axe.
