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.

Webcast on Troubleshooting PCB Defects
January 5, 2018 | RBP Chemical TechnologyEstimated reading time: Less than a minute

RBP Chemical Technology will be holding a webcast on January 9, 2018 on troubleshooting printed wiring board defects. Led by Mike Carano, RBP Vice President of Technology and Business Development, this webcast series will explore the most intricate factors of advanced problem solving of printed circuit board defects and how the interrelationship of both up and downstream processes contribute to scrap product.
Defects, such as interconnect separation, delamination, wedge voids, plating folds, microvoids, surface pitting, and hole wall pull-away, carry significant costs. Many are difficult to solve because the root cause may not be readily apparent and multiple factors may contribute.
The webcast will discuss innerlayer surface preparation and imaging, including cleaning, resist lamination, exposure and developing, and fine line etching; lamination and related defects; and drilling issues and the effects on plating quality.
