電気試験

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 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.
