| Project Background

Foreign matter refers to substances other than the target item that are mixed into raw materials or products.

During the production and use process, the product surface is often prone to be contaminated, corroded, or oxidized. Or due to production defects, negligence and other reasons, foreign matter is introduced and formed, which increases the product defect rate and has a great impact on the product's performance. There are many reasons for the generation of foreign matter, such as impure raw materials, by-products in the reaction, non-standard process control, or immature process formulas.

| Project Overview

This project analyzes foreign matter to obtain the elements and chemical components it contains. Combining with the manufacturer's understanding of the product and process, the real cause of the foreign matter can be found. Then, through the improvement and adjustment of the formula and process by the manufacturer, the generation of foreign matter can be avoided.

This technology is specifically designed for the analysis of tiny embedded foreign matter, surface pollutants, and exudates on products. For example, it can conduct qualitative analysis on abnormal substances such as particles embedded in or exuded from the surface, small-molecule migrants, spots, oily substances, foggy substances, and rubber blooming, to find the pollution source or incompatible components in the formula. It is one of the most commonly used analysis methods for product improvement.

| Test Objective

① Quickly determine the components of foreign matter or impurities, analyze the causes of their generation, and make rectifications to improve the product yield;

② Improve the formula through the analysis of abnormal substances;

③ Eliminate production hazards;

④ Ensure the stability of production.

| Service Products / Fields

Widely used in chemical products, aviation products and their components, automotive products and their components, LCM series products, PCB&PCBA, electronic components, semiconductor products, etc.

| Main Analysis Methods

If there is any contamination or embedded foreign matter in your product, it is urgent to conduct a foreign matter analysis. Otherwise, it may seriously lead to product failure. The analysis engineers at MTT analyze the foreign matter in the product to determine the composition of the foreign matter and the reasons for its formation, and help you solve the problem from the source!

| Surface Foreign Matter Analysis Project

1. Organic foreign matter analysis

A kind of analytical method that, for the organic foreign matter on the product surface, selects specific instruments according to the differences in the form, detection depth, and detection area of the foreign matter, analyzes its organic components, determines its main components, and thus obtains information about the foreign matter.

Under magnified observation, organic foreign matter often shows characteristics such as being relatively transparent and soft.

2. Analysis of inorganic foreign matter

A kind of analytical method that, for the inorganic foreign matter on the product surface, selects specific instruments according to the differences in the form, detection depth, and detection area of the foreign matter, analyzes its inorganic components, determines the elemental composition and content therein, and then analyzes the composition.

Compared with organic foreign matter, inorganic foreign matter shows characteristics such as being harder in texture, having darker and more diverse colors, some having obvious crystal forms, and being less transparent.

3. Analysis of unknown foreign matter

It is mainly a comprehensive analysis carried out when it is difficult to distinguish the type of foreign matter, mainly combining the methods of organic foreign matter analysis and inorganic foreign matter analysis.

For example: embedded foreign matter or abnormal spots in electronic products; surface contaminants, precipitates, oily substances, foggy substances; rubber blooming; yellowing and blackening of industrial products; impurities and by-products of chemical products, etc.

4. Comparative analysis of product abnormal phenomena

The comparative analysis of product abnormal phenomena uses the molecular spectrum characteristics of materials to formulate a rapid consistency detection method to determine the consistency of product materials, thereby analyzing the causes of product abnormal phenomena.
