Abstract

Disclosed is a method to determine the legitimacy of electronic parts. The solution is to use spectrum analysis of individual parts before or after installation to certify the origin of electronic components. Defusing certain identifiable compounds into electronic parts during manufacturing, and then recording each of the spectrums for each electronic component, allows this information to be used to identify the part later.

Item Security via Spectrum Analysis with Pre -Defused "ID" into Semiconductor

Counterfeit electronic parts are becoming a concern. A method is needed to determine whether electronic parts are legitimate.

Radio Frequency Identification (RFID) tags are too expensive and too big to be attached to the smallest electronic parts. For example, how would an RFID tag be attached to a 0201 sized chip resistor or capacitor (0.99 mm x 0.51 mm)? Or, if a lot number, a custom brand, or other symbol is to be printed on a part this small, how would this be printed, and how would it be easily read either before it is installed in an electronic assembly or after it is installed in an electronic assembly?

The solution is to use spectrum analysis of individual parts before or after installation to certify the origin of electronic components. Defusing certain identifiable compounds into electronic parts during manufacturing, and then recording each of the spectrums for each electronic component, allows this information to be used to identify the part later.

This disclosure is one way to solve the counterfeiting problem, as each part's spectrum "DNA" is diffused into each part during the manufacturing cycle, and then read or sampled later for a large lot of parts by spectrum analysis. This provides accurate identification of the electronic parts.

During the manufacturing process of even the smallest of electronic components, a unique compound is diffused into the part to be sampled l...
