Environmental Testing

Simulated test environments are all about preparing products for real-world use. This is accomplished by gaining as much testing experience and performance data as early as possible during the products’ lifecycles. Simulated environmental testing usually involves creating artificial environments for test items to determine their expected resilience to their anticipated environments. Environmental testing sounds simple enough in theory, but there are some real challenges when trying to design a product for its environment.

There are several good reasons for your company to perform environmental simulation testing, and it’s especially important to the overall success of your business. These reasons include:

  • Testing to specific standards and requirements is almost always a requirement of doing business.
  • Providing them with a distinct competitive advantage.
  • All major Test Standards require environmental testing.
  • Simulated environment testing can expose many design flaws early in the design process.

Resolving Electronic Data Processing Unit Failures through PCB Redesign

Introduction

This case study explores a significant challenge faced by our team when repeated failures plagued our electronic data processing unit (EDPU). Through diligent analysis and recommending for a comprehensive redesign of the printed circuit board (PCB) layout, we overcame the issue, ensuring the system’s reliability and longevity. In the fast-paced world of electronics, ensuring the reliability and stability of data processing units is of utmost importance.

The electronic data processing unit had been experiencing persistent failures during the testing. Whatever action taken to overcome the issue was yielding no results as the moment test chamber temperature increases, EDPU would stop functioning. The team reached the impasse. The reliability and performance were compromised, and it was crucial to identify and address the root cause of these failures. The customer requested us for any help. Our team started analysing the problem and started looking into each and every aspect on how thermal management of the PCB board carried out. We used the Infrared thermal camera to see how the heat dissipation happening in the board and do we have to increase the heat dissipation. But what caught us at that moment was the totally something else which no one had even imagined.

Climatic simulation

With thorough analysis and diagnostic testing, we identified that the root of the problem lay in the IC converter, a critical component of the EDPU. IC converter electrical devices that convert the voltage from alternating current (AC) to direct current (DC) which is used to detect amplitude modulated radio signals; supply polarized voltage etc. usually they have very poor current overload capacity, if not managed properly will yield affecting results. This IC converter was not receiving adequate power due to the improper selection and placement of the power supply system. Moreover, during temperature variations, the IC converter was overheating, leading to its premature failure. It became evident that the improper power supply system design and IC converter placement were the core issues.

The Investigation

Our team started a rigorous investigation to pinpoint the issues causing these failures. In the process we subjected the EDPU to various environmental conditions and scenarios to recreate the failures systematically. This helped in understanding the exact conditions under which the failures occurred. Our engineers scrutinized the IC converter and power supply system, paying special attention to their placement, heat dissipation, and performance under temperature fluctuations. We collaborated with both in-house experts and external consultants to gain insights into the details of power supply systems and thermal dynamics.

The Resolution

Upon uncovering the root causes of the EDPU failures, we initiated a comprehensive solution which primarily was redesigning PCB Layout. The key to resolving the issue was a complete redesign of the PCB layout. We recommended to reconfigure the placement of the IC converter and improved its power routing capabilities. This not only resolved the overheating issue but also ensured that it received adequate power, thus preventing failures due to power supply. We further asked to upgrade the power supply system to provide more stable and regulated power to the IC converter, addressing the initial issue of inadequate power supply. Once they are done, we carried out extensive testing to ensure the effectiveness of our redesign, we subjected the revised EDPU to rigorous testing under various conditions, including temperature extremes and real-world usage scenarios.

The Results: The results of our efforts were highly satisfying. Following the redesign of the PCB layout, the electronic data processing unit demonstrated a remarkable improvement in reliability and stability. Failures were not observed, and functional operations could proceed smoothly without the disruptions we had previously experienced.

This case study underscores the significance of meticulous analysis and innovative problem-solving in the world of electronics. It also emphasizes the value of continuous improvement and the dedication to delivering dependable and robust systems to our clients. Through our unwavering commitment to quality, we transformed a persistent challenge into a success story, ensuring the longevity and reliability of our electronic data processing unit.
