Abstract

In today’s world, people are surrounded by diverse electronic devices. Their integral parts are electronic components. In recent years, an increasing incidence of counterfeit electronic components has appeared which may compromise reliability, functionality and other related purposes. The aim of the paper is to determine whether Raman spectroscopy is a suitable method for assessing the authenticity of electronic components on the basis of material analysis. Raman spectroscopy is a powerful method for material identification offering specific information on molecular level. The focus of measurements was on materials of packages and the markings. The polymer-based and ceramic-based electronic components were analysed as well as the paints of the markings. The results of this preliminary study positively indicate the potential to distinguish different materials of electronic components by Raman spectroscopy.

Highlights

The incidence of counterfeit electronic components is an increasingly common phenomenon in our modern world
There are several types of counterfeit electronic components on the market, to a lesser extent empty cases without any functionality, and sophisticated counterfeits that are hardly recognizable from the original
Counterfeit electronic components are most prevalent in mainland China [2]

Summary

Introduction

The incidence of counterfeit electronic components is an increasingly common phenomenon in our modern world. In the field of electronics, it is fakes of complex products of established companies, and the number of counterfeits of electronic components themselves that are growing dramatically. These are both, passive components (e.g. capacitors, precision resistors) as well as active components (integrated circuits of various complexity, transistors, etc.) [1]. There are several factors influencing the penetration of counterfeit components into product sets. Counterfeit electronic components are most prevalent in mainland China [2]. Types of counterfeit can be classified into several categories, such as recycled, remarked, defective, cloned, etc. Types of counterfeit can be classified into several categories, such as recycled, remarked, defective, cloned, etc. [3]
