Quiet Power: An Evolution in PCB Design Costs

09/04/2024 | Istvan Novak -- Column: Quiet Power
In this column, I want to cover my experiences, particularly where costs are concerned, with printed circuit boards from the 1960s to the present day. I grew up in an apartment building in downtown Budapest, where I began doing hobby projects building circuits from our kitchen table. Now, I’m lecturing about the most recent advances in signal integrity at Oxford University. We’ve come a long way. Over the decades, new technologies allowed users to have more layers, lower-loss dielectrics, fine-pitch surface connections, blind and buried vias, and HDI and HDI+ board constructions that allow us to design higher-performing systems. I expect this trend to continue.

Connect the Dots: Designing for Reality—Electroless Copper

08/28/2024 | Matt Stevenson -- Column: Connect the Dots
Roll up your sleeves because it's time to get messy. In a recent episode of I-Connect007’s On the Line with… podcast, we discussed electroless copper deposition. This process deposits a copper layer into the through-holes and vias of what will eventually be a PCB. Electroless copper deposition feels like a black box to many people. It sort of looks like a black box, too. The boards go in one side, come out the other, and emerge differently. So, let's crack open that black box and look inside.

Elementary, Mr. Watson: Debunking Misconceptions in PCB Design

08/22/2024 | John Watson -- Column: Elementary, Mr. Watson
PCB design can be likened to the poem, “The Blind Man and the Elephant” by John Godfrey Saxe. In the poem, six blind men of Indostan “to learning much inclined,” went to see the elephant “that each by observation, might satisfy the mind.” The first man fell against the elephant and concluded it was like touching a wall. The second man felt the elephant’s tusk and exclaimed, "It is very like a spear." The third blind man, feeling the vast and squirming trunk, decided it was a snake. The fourth man felt the elephant's leg and said the elephant “is very like a tree." The fifth man touched the massive ears and decided an elephant is very like a fan. Finally, the sixth blind man, feeling the elephant’s swinging tail, proudly proclaimed, "I see, the elephant is very like a rope."

Cost-optimize Your PCB Design and Specifications

08/20/2024 | Erik Pedersen and Richard Koensgen, ICAPE Group
Knowledge is the key to identifying the small details that makes the big cost difference for your printed circuit board. There are many types of printed circuit boards and multiple choices between the development of schematic and BOM to PCB technology selection, electronic PCB design, mechanical and physical properties, and PCB specification.
