Measuring of Organic Components in Fiberglass Using the TOC-5000A Solid Sample TOC Analysis System

Introduction

Even though we do not come into visual contact with them, printed circuit boards equipped with IC and LSI - the hearts of electric equipment - are true pillars of our society as they are an integral part of our lives being used in a variety of electric and electronic products. On the whole, such printed circuit boards are made of fiberglass impregnated with thermosetting resins such as phenol resin, epoxy resin, polyimide (PI). However, as organic components affect the mechanical features such as strength and hardness and electric conductivity, ultra-efficient supervision is required to prevent poor product quality.
