PCB Fault Detectors

PCB fault detection and board comparison are key steps while servicing equipment.

We have partnered up with Prot Ar-Ge, who designs and manufactures electronic-based projects such as FAult Detector and PC OScilloscope which are cost-effective and efficient tools that give in-depth knowledge about the various technical specifications of the board you intend to work on and further they determine and troubleshoot faults at all type electronic circuit boards. They are basically computer-based VI testers.

There are three products in this category – the FADOS7F1, FADOS9F1 and FADOS MUX

V-I testing in troubleshooting Populated Printed Circuit Boards (PPCBs) offers several advantages

V-I testing offers numerous advantages in troubleshooting PCBs, including comprehensive analysis, localized fault detection, quantitative data, real-time monitoring, non-invasiveness, versatility, cost-effectiveness, and support for predictive maintenance strategies. These benefits make it an invaluable tool for ensuring the reliability, performance, and longevity of electronic systems.

Comprehensive Analysis

V-I testing allows for the simultaneous measurement of voltage and current across various points in the circuit. This provides a comprehensive view of the electrical behavior of the PCB, aiding in the identification of abnormalities and faults.

Localized Fault Detection

By analyzing voltage and current at specific points on the PCB, V-I testing enables the localization of faults to specific components or sections of the circuit. This targeted approach streamlines the troubleshooting process, reducing the time and effort required to identify and rectify issues.

Quantitative Data

V-I testing provides quantitative data regarding voltage and current levels, allowing for precise analysis of electrical characteristics such as voltage drops, current spikes, and power consumption. This data facilitates a deeper understanding of the PCB’s performance and helps in diagnosing underlying problems accurately.

Real-Time Monitoring

V-I testing can be conducted in real-time, enabling continuous monitoring of the PCB’s electrical behavior during operation. This real-time feedback allows for immediate detection of anomalies or deviations from expected values, facilitating prompt corrective action to prevent damage or system failure.

Non-Invasive

V-I testing is generally non-destructive and non-invasive, meaning it can be performed without physically altering or damaging the PCB. This preserves the integrity of the circuit and minimizes the risk of causing additional problems during troubleshooting.

Versatility

V-I testing techniques can be adapted to various types of PCBs, including those with complex designs or multiple layers. Whether testing simple circuits or intricate electronic systems, V-I testing remains a versatile diagnostic tool for identifying faults and optimizing performance.

Cost-Effectiveness

While specialized equipment may be required for V-I testing, the cost is often justified by the efficiency and accuracy it brings to the troubleshooting process. By quickly pinpointing faults and minimizing downtime, V-I testing can ultimately save time and money in repair and maintenance operations.

Predictive Maintenance

Through periodic V-I testing, trends in voltage and current behavior can be analyzed over time to predict potential failures or degradation in performance. This proactive approach to maintenance helps prevent unexpected downtime and extends the lifespan of PCBs and associated equipment.

FAQ’s

FADOS, which stands for Fault Detector & Oscilloscope, is designed to enhance efficiency, accuracy, and sustainability in electronics testing and PCB troubleshooting processes. It facilitates accelerated fault detection.

FADOS utilizes Windows software to perform real-time V-I (voltage-current) comparisons without powering the Device Under Test (DUT). It can store V-I data from working boards for comparison even when a working board isn’t available.

FADOS is applicable across various industries and systems, including Automotive, Aerospace, Industrial Automation, Home Appliances, Electronic Devices, Medical Devices, Textile Industry, and Power Systems.
