Current IssueThe Hole Truth: Via Integrity in an HDI World
From the drilled hole to registration across multiple sequential lamination cycles, to the quality of your copper plating, via reliability in an HDI world is becoming an ever-greater challenge. This month we look at “The Hole Truth,” from creating the “perfect” via to how you can assure via quality and reliability, the first time, every time.
In Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.

HDP User Group Launches New High Frequency Measurement Project
November 15, 2016 | PRWEBEstimated reading time: 1 minute
The High-Density Packaging (HDP) User Group, headquartered in the United States, is launching a new project that will focus on understanding the impact of moisture on high-frequency measurements of printed circuit board material.
As electronic products increase in functionality and interconnect speeds approach 40 GB/sec, the need to measure substrate material performance becomes increasingly important and demanding.
This is the third project in this series. Phase one reviewed and compared the different types of high frequency test measurements that are used in the industry for measuring dielectric constant (Dk) and dissipation factor (Df) at higher frequencies. Moisture content was identified as a significant factor in the testing.
Phase 2 was initiated to establish a test protocol for the accurate measurement of Dk, Df, and weight gain. Weight gain is used to measure moisture content. The objective of Phase 2 was only to establish a test protocol to accurately measure weight to 4 decimal places.
Now that the measurement protocol has been verified, Phase 3 of this project proposes to evaluate the effect of moisture on each of the high frequency Dk and Df test methods. During the testing and analysis of the earlier phases of this project, it was determined that differences in moisture content were found to contribute up to a 20 percent difference in the measured Df values of some laminate materials tested. Phase 3 will use several laminates. Some low Df, some mid Df, and some high Df.
Please contact Jack Fisher at fish5er@hdpug.org to be added to project notification list and participation in this investigation. You will be informed of the next project call, tentatively to be held in early November.
