At HTC, we believe quality and reliability are paramount to our customer's success. With this belief in mind, we 100% test our products twice. We do an in process test before we send a production run to encapsulation/labeling and then perform a final test to ensure the quality has not been compromised. We use state of the art equipment and follow guidelines set by our customer or international standard such as UL. All test results can be provided and stored per customer request.
