What tests do chargers that meet safety standards need to go through?

For 19 years, it has only made safety power supply, with rich production experience and independent R & D capability, and is the benchmark of the power supply industry.Today, Xiaobian will explain to you what tests are needed for power adapters that meet safety standards?

IQC incoming inspection

Inspection purpose: to eliminate the delay in delivery due to poor material manufacturing process caused by poor materials on the line

Inspection standard: raw material inspection specification

Inspection equipment: withstand voltage meter, transistor tester, bridge, DC current, leakage current tester, environmental protection tester, swing tester, salt spray tester, flame retardant tester, etc

SMT first article inspection

Inspection purpose: to ensure that the components attached to the production model are completely consistent with the customer's assembly drawing and bill of materials, and prevent bad flow into the next process

Inspection standards: Refer to Bom, gerber data, measure and test each material of the first board

Inspection equipment: TH2817B, TH2830A, magnifying glass

IPQC process control

Inspection purpose: to ensure the quality of the power adapter formation process

Inspection standards: refer to BOM, product specifications, product test specifications, IPC-A-610E, product reliability verification specifications, etc

Inspection equipment: ATE, electronic load, high voltage meter, ripple tester, leakage current tester, etc

Semi-finished product testing

Inspection purpose: to ensure the quality of semi-finished products in the process of formation

Inspection standards: refer to BOM, product specifications, product test specifications, IPC-A-610E, etc

Inspection equipment: ATE, electronic load, ripple tester, etc

Finished product aging test

Inspection purpose: to ensure the service life of the power adapter

Inspection standards: product specifications, product test specifications, etc

Inspection equipment: computer automatic aging system

QA spot checks

Inspection purpose: to ensure the quality of power shipment

Inspection standards: refer to BOM, product specifications, product test specifications, product reliability verification specifications, finished product appearance inspection specifications, etc

Inspection equipment: ATE, high voltage meter, ripple tester, leakage current tester, etc

EMC/EMI spot check verification

Inspection purpose: to ensure that the power adapter meets the electromagnetic compatibility requirements

Inspection standards: refer to EN55032, EN55024, EN55020, etc
