[Case Study] The Importance of Electrical Testing in EMS Companies

basic information

**Benefits of Introducing Flying Probe Testers** Responsiveness to Specification Changes: By utilizing a fixture-less (no fixture required) tester, it is possible to quickly respond to design changes. This allows for a smooth progression from prototype to mass production. High-Quality Manufacturing: By pursuing high quality from the prototype stage, the defect rate during mass production can be reduced. It is possible to verify the appropriateness of processes such as solder printing and reflow, where temperature management is crucial. Cost Reduction: Reduces the costs and time associated with re-manufacturing fixtures. By pre-checking and verifying mass production data, it reduces the costs related to defects during mass production. Mistake Prevention: Early detection of mistakes or wiring defects during the rework process when replacing components. Electrically verifies whether various profiles (temperature, electrical characteristics, etc.) in the prototype and mass production processes conform to specifications.

**Effects of Implementation** Rapid problem-solving during the prototype stage: Even when design changes or component changes occur, real-time electrical inspections are conducted to quickly identify issues. Stabilization of mass production processes: By confirming the compatibility of processes and components before mass production, the occurrence of defective products is prevented in advance. Improvement of customer satisfaction: By consistently supplying high-quality products, customer trust is gained. **Application Examples** After-sales service: Checking and reconfirming electrical characteristics during circuit board repairs.
