Importance of Acid Value Determination

The acid value of a soldering flux is a crucial parameter that affects the performance and reliability of solder joints. It is a measure of the amount of acid present in the flux, which can influence the flux's ability to remove oxides from metal surfaces and promote wetting. Accurate determination of the acid value is essential for:

• Ensuring optimal soldering performance
• Maintaining the integrity of electronic components
• Preventing corrosion and other long-term reliability issues

Test Methods Included

The standard provides two primary methods for determining the acid value:

1. Potentiometric Titration Method

This method involves the use of a potentiometer to measure the potential difference between two electrodes in a solution. It is a precise and reliable technique that provides accurate results, making it ideal for applications where high precision is required.

2. Visual Titration Method

The visual titration method is a more traditional approach that involves the use of indicators to determine the endpoint of a titration. This method is straightforward and cost-effective, suitable for situations where quick assessments are needed.

Who Should Use This Standard?

The BS EN ISO 9455-3:2020 standard is designed for a wide range of professionals, including:

• Quality control engineers in electronics manufacturing
