Approximately once every month, a defect was being found. Instruction regarding the proper procedure was being given, but there were some deviations in the way, it was being carried out depending on the operator.

- The rate of defect occurrence improved dramatically.
We typically set our parts in a multi-rack vacuum plasma equipment for cleaning. At a frequency of about once per month, we were finding a defect, either due to an equipment setting failure or possibly as the result of incomplete cleaning. Although we have a set operation procedure, each operator was executing this procedure with a slightly different level of motivation and awareness. Accordingly, it was difficult to avoid the occurrence of such defects completely. Our aim was to find a simple and straightforward method for improving our quality management.
We found PLAZMARK™ at an exposition we attended. When we used the free sample they gave us, it showed clear changes in color, which made it very easy to check if the treatment had been carried out properly, or whether the settings had been correct. Impressed with the simplicity, we opened discussions with our Quality Management Department and decided to introduce PLAZMARK™ right away. We installed a PLAZMARK™ card for each shelf of the equipment where our parts were set. Now, when cleaning is completed, we compare the color of each card with the color sample to make sure that all the parts have been properly cleaned.
Outcome: Defect occurrence was decreased dramatically. Thanks to its cost-friendliness, overseas plants were also able to purchase the product easily, without an approval of the headquarter. The simple visual evaluation it allows for has been perfect for local employees to ensure quality management.
