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.

Inner Layer Precision & Yields Explored in December 2024 Issue of PCB007 Magazine
December 16, 2024 | I-Connect007 Editorial TeamEstimated reading time: Less than a minute

Inner Layer Precision & Yields
As technology advances, the cost of a finished circuit board can amount to some very big numbers. Building accuracy into your inner layers as well as being able to assess their pass/fail status as early as possible is critical. Thus, whether automation cuts down on handling issues, additional in-process testing identifies defects earlier than final test, or you replace an old line with a superior process that improves product quality, increasing the accuracy in your inner layer production is essential for all PCB fabricators. Not doing so will ensure that, eventually, you will no longer be in this game. In this month’s PCB007 Magazine, we take a close look at building precision into your inner layers.
