Current IssueInner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.
Alternate Metallization Processes
Traditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop.

Comparing Apples to Apples
by Sandra Ruroede
Recently, I went to a store to try on wedding dresses. I tried on eight dresses that were all the same size. Of the eight dresses, six fit and the other two did not. In fact, I would say that one of the dresses was approximately two "sizes" too small, yet the size on the tag was identical to the other seven dresses. The sales associate explained that wedding dresses tend to run smaller than regular clothes. Hmmm. That didn't explain why two of the dresses didn't fit while the other six did. And it brought up another question: Why are there no standard clothes sizes?
Why do wedding dresses "tend to run smaller"? Smaller than what? If there are no industry-accepted standards, how can the customer shop in a time-effective and cost-effective manner?
Why do I bring up clothes standards in an electronics magazine? Simple: Right now there are no accepted industry standards for placement machines, reflow ovens, inspection machines, etc. Customers are not obtaining all of the information needed to make educated decisions. And most customers pay a lot more for SMT capital equipment than they do for clothing.
