high quality with good price and service, the package comes quickly

The supplier provided affordable prices for their sputtering targets, and they delivered them quickly and on schedule, just as promised. However, one of the targets completely cracked, another melted/ deformed during the deposition process, and the third one, the Cu back bonding, failed and melted as well. I'm unable to determine whether the issue stemmed from the quality and manufacturing of the target or from our lack of experience in working with such targets.
