電気試験

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.

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.

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.

An in-circuit test (ICT) is a method of electrical testing that checks the components mounted on a PCB individually for shorts, opens.

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.
