BGA or CGA: When Is It Right for You?

May 25, 2015 | Barry Matties, I-Connect007

In this interview with TopLine President and Founder Martin Hart, I-Connect007 Publisher Barry Matties focuses on column grid array (CGA) and how CGA can solve delamination problems. CGAs, also known as CCGA, are not necessarily new but are making a strong comeback in the high reliability market.


Learning the Curve

Beyond Design by Barry Olney
Currently, power integrity is just entering the mainstream market phase of the technology adoption life cycle. The early market is dominated by innovators and visionaries who will pay top dollar for new technology, allowing complex and expensive competitive tools to thrive. However, the mainstream market waits for the technology to be proven before jumping in. Power distribution network (PDN) planning was previously overlooked during the design process, but it is now becoming an essential part of PCB design. But what about the learning curve? The mainstream market demands out-of-the-box, ready-to-use tools.

The Utility Belt

Tim's Takeaways by Tim Haag
The utility belt is a great thing to have. Batman would be long dead without his, and Tim “The Tool Man” Taylor would be useless without his. But for a circuit board designer, a utility belt is equally important. All of us at one time or another will have questions about the CAD system we use, and one essential tool to have in your utility belt is a list of people you can go to for help. At the top of this list should be your CAD system’s friendly customer support staff (like me).

RF Power Capabilities of High-Frequency PCBs

Lightning Speed Laminates by John Coonrod
I often hear this question: “How much RF power can be applied to a high-frequency PCB?” My answer sometimes surprises engineers. I tell them that they can put as much RF power into the PCB as they want, with the assumption that the PCB does not exceed its maximum operating temperature (MOT). MOT refers to the maximum temperature to which a circuit can be exposed without degradation of critical properties.
