Automated Optical Inspection (AOI)

Automated optical inspection is used to detect any surface-level defects, such as missing components, incorrect component placement, or solder bridging. This technology enables RAYMING to quickly and accurately identify potential issues and take corrective action.

Electrical Testing

Electrical testing is performed to verify the functionality and performance of the assembled PCB. This includes:

1. Continuity testing
2. Insulation resistance testing
3. Voltage testing
4. Functional testing

These tests ensure that the PCB meets the required electrical specifications and functions as intended.

Environmental Testing

Environmental testing is conducted to evaluate the PCB’s ability to withstand various environmental conditions, such as:

1. Temperature cycling
2. Humidity exposure
3. Vibration and shock

This testing helps to ensure that the PCB will perform reliably in its intended operating environment.

Compliance with Industry Standards

IPC Standards

RAYMING adheres to the following IPC standards in their PCB production:

Standard	Description
