Dear Martin,

A main reason we asked your company to perform wave solder process training for our facility in China was due to the tremendous, positive impact your program had at our Mexico facility. I'm pleased to tell you that the training and troubleshooting performed at our China facility has been equally extraordinary.

Success is the uncommon application of common knowledge. Once you conveyed the basics, you showed us how easy it is to eliminate wave solder defects, implement specific daily process guidelines to prevent their recurrence, and take complete advantage of the critical data provided by our Optimizer.

We are especially grateful for your tackling a bridging problem on the bottom-side QFP's of our mixed technology boards, and setting the record straight on the relationship between fluxer performance, flux chemistry and the assessment of flux application.

It is a clear disadvantage to wave solder without the benefits of daily Optimizer data and procedures. Now, I thank you for taking us many giant steps ahead, to having a clear advantage from your training program to improve our board quality and lower our manufacturing costs.

Best Regards,
