The Pulse: Commonsense Cost Cutting

08/29/2024 | Martyn Gaudion -- Column: The Pulse
One difference between engineering and pure science is that engineers (in most situations) are looking for cost-effectiveness. They do so by designing the most appropriate level of technology to maximize profitability with acceptable levels of application functionality. One area that is often overlooked is the energy cost of PCB production. At a recent EIPC conference, Dr. Maarten Cauwe of IMEC in Belgium presented a combined study of the lifecycle impact (LCI) of electronics systems and subassemblies. The study looked at the supply chain as well as the energy impact of HDIs.

Asymmetric Hybrid Printed Circuit Board Design: Warpage Considerations

The printed circuit board (PCB) accounts for a significant portion of the PCBA’s (printed circuit board assembly) BOM (bill of material) cost. Designs with hybrid PCB stackup are adopted to reduce the cost of the PCB by using less expensive laminate materials in layers that do not have routings for high-speed signals (e.g., power and ground layers). The conventional hybrid PCB stackup design is symmetrical in the middle. This engineering technique has been employed in the data center industry for quite some time. To extend the idea and optimize the purpose of hybrid PCB stackup design, the feasibility of an asymmetric hybrid stackup is currently being studied.

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."
