Electrical Testing
In electronic manufacturing, electrical testing is a critical step to verify the integrity and functionality of Printed Circuit Board Assemblies (PCBAs). This pivotal phase in the meticulous testing and quality assurance process ensures that the assembled boards meet the required specifications and perform as intended, emphasizing the evaluation of electrical performance and safety across components, subsystems, and complete devices.
We rigorously examine the functionality of electrical components to verify that they perform as intended. This includes assessing power supply, signal integrity, and the overall electrical behavior under varying conditions.
Ensuring the safety of electronic devices is paramount. Our testing protocols adhere to international safety standards, covering aspects such as insulation resistance, grounding, and protection against electrical hazards.
We go beyond surface-level assessments. Our electrical testing covers a spectrum of parameters, providing a comprehensive evaluation of your electronic devices and identifying potential weaknesses that could impact performance.
- Application of voltage to net.
- Holding voltage for dwell time to be able to detect any stray current.
- Move to the next pair.
Types of electrical testing include: Continuity Testing: Checks for open circuits. Insulation Resistance Testing: Measures the resistance between conductive parts and the ground or between two conductive parts. High Potential (Hi-Pot) Testing: Applies high voltage to ensure insulation integrity. Electrical Function Testing: Verifies the operational functionality of a device.
Electrical testing is crucial for: Ensuring the safety and reliability of electrical systems and components. Detecting manufacturing defects and preventing product failures. Complying with industry standards and regulations.
An in-circuit test (ICT) is a method of electrical testing that checks the components mounted on a PCB individually for shorts, opens.
An electrical function test evaluates an electronic assembly, such as a PCB, to ensure it performs its intended electrical functions correctly. This involves applying power to the assembly and simulating operational conditions to verify functionality and compliance with design specifications.
In-Circuit Testing (ICT): Tests each component on a PCB for shorts, opens, values, and functionality. Flying Probe Testing: Uses movable probes to test components and connections on small batch PCBs without a custom fixture. Functional Testing: Simulates the operational environment and verifies the PCB performs as intended.
A flying probe test uses movable test probes to make contact with components and test points on a PCB. It's flexible and does not require a custom test fixture, making it ideal for prototyping and low-volume production.
