The Chemical Connection: Getting the Best from Your Cupric Chloride Etchant

12/04/2024 | Don Ball -- Column: The Chemical Connection
Over the past several months, we have received a lot of questions from our customers about cupric chloride etching—mostly about how to improve etch quality, but also about process problems. Most of them were easily dealt with, but the questions arose because the people involved in running the etching process were not aware of the finer nuances involved in using cupric chloride as the primary etchant. (They don’t have courses on etching in most colleges and trade schools.) I thought this might be a good time to summarize some things I have learned in my 50 years of experience with cupric chloride etching and clear up some of the confusion.

Standard of Excellence: Hiring for Quality Positions in Manufacturing, Engineering, and Management

11/26/2024 | Anaya Vardya -- Column: Standard of Excellence
In continuing my series on finding, signing, and keeping good people for your company, this month we discuss hiring good people for your quality department. Even when hiring was easier, hiring for the quality department has always been especially challenging. It takes a special kind of person: someone with attention to detail, someone ready to stand for his or her convictions, and someone who can stand up under pressure when the company needs to ship product and the quality manager refuses to because it is not up to par. The quality department is the very soul of any manufacturing company.
