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.

Technic’s Non-Cyanide Gold Process Eliminates Discoloration of White Solder Mask
August 20, 2015 | TechnicEstimated reading time: 1 minute

Techni IM Gold AT8000, Technic’s new non-cyanide gold process released earlier this year, eliminates discoloration of white solder mask when using ENIG as a final finish.
Technic has conducted extensive research to determine and eliminate the cause of discoloration of white solder mask which occurs during ENIG processing. It has been established that this discoloration is directly related to the chemistry of the immersion gold processes commonly used for these applications. Materials in these processes react with the titanium dioxide in the solder mask pigmentation and produce the red or pink discoloration after SMT reflow.
Techni IM Gold AT8000 eliminates the compounds found in the typical cyanide based immersion gold processes which react with the titanium dioxide to produce this discoloration, thereby preserving a bright white solder mask after SMT reflow.
“With a marked increase in the number of LED applications requiring white solder mask, it is critical that a high level of reflectivity be achieved under a variety of conditions. Techni IM Gold AT8000 has performed exceptionally well in being able to address the white solder mask discoloration issue. Technic remains dedicated to the ongoing research required to solve industry issues and deliver the highest performing products,” said Eric Stafstrom - Global Product Manager.
