METHOD OF MANUFACTURING A SYSTEM IN PACKAGE
First Claim
1. A method of manufacturing a system in package, comprising:
- providing a substrate;
mounting a test controller on the substrate;
mounting a first die on the substrate, the first die being conductively coupled to the test controller;
testing the first die by providing the test controller with a plurality of test signals and communicating at least a subset of the test signals between the test controller and the first die;
mounting a second die on the substrate, the second die being conductively coupled to the test controllers; and
testing the second die by providing the test controller with a first further plurality of test signals and communicating at least a subset of the first further plurality of test signals between the test controller and the second die.

Abstract
A system in package (10) has a, preferably wireless, test controller (20) for testing each die (30) after it has bee mounted onto the substrate of the system in package (10), and a faulty die (30) is repaired before a next die (30) is mounted onto the substrate (15). This way, the system in package (10) can be tested during the intermediate stages of its manufacturing, thus ensuring that all dies (30) function correctly before sealing the dies in the single package. Consequently, a method for manufacturing a system in package (10) is obtained that has an improved yield compared to known manufacturing methods.
