Week 21 Quality Report



Since 2009, White Horse Laboratories has been publishing our Weekly Quality Reports, which is a listing of the devices that have had over 5% lot failure in electrical testing or the buyer has rejected the lot following results of inspection methods

While this list is not exhaustive (for example, a 5% failure rate may be too high or some buyers may accept devices in a physical condition that others would not), it is intended to an indicator as to what is going on in the market and is a reminder to be aware of the risks of sourcing without adequate quality control measures in place.
