1. Overview of Vietnam's Electronics Industry Market

According to the General Statistics Office, as of September 2024, Vietnam's exports of electronics, computers, and components reached $52.8 billion. On the global technology map, Vietnam ranks 5th in computer and component exports and 2nd in mobile phone exports.

Electronics manufacturing plants, with investments ranging from tens of millions to billions of dollars from major corporations and enterprises from South Korea, the U.S., and other countries, have played a pivotal role in helping Vietnam maintain an annual technology export turnover exceeding $100 billion in recent years.

The primary export markets for Vietnam's electronics sector include the U.S., Europe, China, and South Korea. In the past year alone, exports of computers, electronic components, and mobile phones to Europe and the Americas totaled $56.9 billion, accounting for nearly 45% of total export revenue.

With the presence of multinational manufacturers such as Samsung, Foxconn, and Intel, along with commitments to expand production, Vietnam continues to attract interest from global corporations exploring investment opportunities. This signals a promising future, positioning Vietnam for transformation, acceleration, and breakthrough growth.

Amid the evolving electronics manufacturing landscape and the rapidly increasing production demand, manufacturers in Vietnam face significant challenges related to machinery and production equipment. There is a growing need for reliable suppliers that can provide timely equipment, spare parts, and maintenance solutions to support seamless and efficient production.

2. The Importance of Encoders in the Electronics Industry

In the electronics industry, encoders play a crucial role in automation systems by enabling precise control and monitoring of equipment operations. According to a report by Markets and Markets, the global encoder market is projected to reach $3.7 billion by 2026, growing at a CAGR of 8.6% per year.

Within electronic device manufacturing, encoders support robotic systems, fixed arms, conveyor belts, and quality control systems. Advances in motion and measurement technology have laid the foundation for further innovations, including the miniaturization of components. This includes smaller semiconductor molds in front-end manufacturing, increased chip complexity in back-end processing, and higher component density on printed circuit boards (PCBs), all of which have propelled the electronics industry forward.

3. Types of Encoders for the Electronics Industry

There are two main types of encoders: Incremental Encoders and Absolute Encoders. Each type has its own distinct characteristics, an absolute encoder stores the absolute position value even when power is lost. When power is restored, it can immediately provide the exact position without needing to recalibrate the reference point. In contrast, an incremental encoder generates pulse signals to measure speed and direction of rotation, commonly used in motor control and motion monitoring applications.

These two encoder types exist in two physical forms:

  • Rotary Encoder: Used in robotic systems and conveyor belts.

  • Linear Encoder: Supports precise position measurement.

Depending on operational requirements and machinery compatibility, electronics manufacturers can select the most suitable encoder type. Today, the market offers a wide range of encoders with diverse specifications from leading brands such as RSF, Heidenhain and more, ensuring optimal solutions for industrial automation.

4. When to Replace an Encoder?

Unexpected machinery component failures can disrupt production efficiency. Therefore, plant engineers should be aware of common encoder issues to proactively maintain or replace faulty components, ensuring seamless operations.

Here are some common encoder failures:

  • Encoder Malfunction: This occurs when internal components fail to generate or transmit accurate waveforms. In such cases, replacing the encoder or repairing internal components is necessary.

  • Connection Issues - Faulty Cables: One of the most frequent causes of encoder failures, especially during maintenance. If cables are exposed, short-circuited, or have poor contact, they should be replaced immediately. Additionally, ensure cables are not overly tight, as this can loosen or break solder joints. Secure connections properly to maintain stable operation.

  • Power Supply Issues: If the supplied voltage is too low or exceeds the encoder's resistance threshold (which varies by brand and model), the encoder may become unstable. This can result from weak power sources or excessive transmission loss through cables. Inspect and repair the power supply or replace faulty cables if needed.

  • Improper Installation: If the encoder is not securely mounted, positional accuracy may be compromised, leading to severe misalignment. Regularly check and tighten the encoder to ensure secure installation.

  • Other factors may also cause encoder failures, sometimes requiring a full replacement. If you encounter any issues, AMS's experienced engineers are ready to assist you. Contact us at 028 3868 3738 for support!
