| Project Background

IPC-A-610 is a globally recognized acceptance standard for electronic assembly, used to regulate the quality of electronic products. It covers all aspects of electronic assembly and provides guidelines to ensure product performance and reliability.

| Project Overview

Physical property testing of printed boards (usually referring to printed circuit boards, PCBs) refers to various tests on their physical properties and material characteristics. These tests are crucial for ensuring the quality, reliability of PCBs and meeting specific application requirements. The following are some key physical property testing items and their significance:

Board peel strength: Measures the bonding strength between the copper foil and the substrate. The test is usually conducted under normal conditions, after thermal stress (such as after dip soldering), or after chemical treatment.

Moisture absorption rate: Measures the degree to which the material absorbs moisture. A high moisture absorption rate may lead to board popping (delamination) during soldering, a decrease in electrical performance (such as an increase in the loss tangent), and reliability issues.

Bending strength/flexibility: Evaluates the bending resistance of rigid boards; evaluates the bending life of flexible boards.

Adhesion test: Tests the bonding strength between the solder mask ink, character ink and the substrate or copper surface (usually using the tape method).

| Test Objective

1. Ensure reliability: Predict the long-term lifespan and failure risks of PCBs in the usage environment (temperature, humidity, vibration, chemicals, etc.) of the final product.

2. Meet process requirements: Ensure that PCBs can withstand subsequent assembly processes (such as SMT reflow soldering and wave soldering) without damage.

3. Comply with specifications and standards: Meet customer requirements, industry standards (such as IPC standards), and safety certifications (such as UL).

4. Quality control: Serve as a key quality control point in the production process.

5. Problem diagnosis: When a PCB fails, physical property testing is an important means to analyze the root cause.
