Understanding PCB Manufacturing: Odd Layer PCB Boards

Our cookbook of PCB recipes includes an assortment of odd layer PCBs. About 8% of PCB boards we are asked to produce are comprised of an odd number of layers. But unless you have a specific requirement, it is usually best to design a multilayer board with an even number of layers. Reducing an even layered board by one layer may seem like a cost-saving move, but from a PCB perspective it is not. It may actually increase the cost as well as lead-time and leave you with a warped PCB board which may not meet your expectations. Let's look at »»

A Quality Tragedy about a Chicken Dance and a PCB Board

One common sense business rule is: Sound economic decision making is a requirement for any company intent on succeeding. This rule applies to all aspects of the business, including the quality department. The following is a series of events from my past with firms who require aliases. The supplier (who will be referred to simply as Fowlmouth) and the customer (who we will call Foghorn) are located within a thirty minute drive of each other and it’s very, very important to note neither is a government agency. I have had the good fortune to work with a few outstanding organizations whose »»

What You Should Know About Immersion White Tin PCB Manufacturing

If you work with printed circuit boards and PCB manufacturing in your business, then you have probably already heard of immersion white tin, but may have questions about how it actually works and whether it's a process that you should care about. Given that we are leaders in immersion white tin PCB fabrication here at Omni, it goes without saying that we are heavily in favor of its use. To understand why, you first have to understand the reason behind our preference for white tin in the first place. Traditionally, circuit boards have been finished with a coating of material, usually containing »»

How to Avoid PCB Board Delays in CAM

CAM (computer-aided manufacturing) is the art of translating a PCB board designer’s creative CAD (computer-aided design) output into information required in our manufacturing processes. Our processes require your computer generated files to be converted into phototooling films and drill/router files which will allow us, the printed circuit board manufacturing facility, to produce a custom PCB to your specifications. Our challenge is we rarely know your design intent and in PCB manufacturing, as in life, Murphys Law applies. Your CAD data must completely and unambiguously specify the PCB you want; otherwise, we will make something else. Being human, mistakes happen. We would »»
