Focus Tech Announces New Website and Product Showcase
March 28, 2023 | Focus TechEstimated reading time: 1 minute
Tempe, Arizona based Focus Tech announces a new website that focuses on its offering in specialty chemical and process control system manufacturing for the printed circuit board and general metal finishing industries. Focus Tech is the only supplier to the PCB industry that designs and manufactures both process chemicals and control systems.
“Focus Tech is proud to roll-out a new company website this week,” commented Scott Campbell, Focus Tech founder and president. “The site www.focustechchem.com features over 50 product pages for a variety of chemicals we manufacture for a variety of applications. In two clicks, viewers will find technical information on what we offer. We designed it from the ground up to make it easy to access and navigate all our information.”
Focus Tech product lines include anti-foam, anti-tarnish, copper cleaners, etch chemicals, developers, strippers, as well as others commonly used in the manufacture of printed circuit boards and general metal finishing. Focus Tech also manufactures process control equipment and offers a variety of services to PCB fabricators.
Focus Tech is known for responding quickly to customer needs and evolving technology by providing custom chemical formulations and controller designs tailored to the specific requirements of a given process.
Campbell added, “Last year, we moved to a new 47,000 square-foot facility with significant capital investment to improve and streamline all operational, research & development, and manufacturing processes. This has allowed Focus Tech to expand its capabilities particularly in toll blending capabilities. One click on the website will take viewers to a robust overview of what we can do in chemical blendings, custom process controls, and services.
“Our new R&D laboratory allows various types of testing including wet titration, atomic absorption and UV/VIS spectroscopy, and cross sections. Our access to a scanning electron microscope and energy dispersive x-ray analysis equipment round out our test services.”
A part of The Redfern Companies, Focus Tech’s products, equipment, and services are distributed by Insulectro leveraging the distributor’s sales team and 11 stocking locations in North America.

Book Excerpt: The Printed Circuit Designer’s Guide to... DFM Essentials, Ch. 1
10/25/2024 | I-Connect007The guidelines offered in this book are based on both ASC recommendations and IPC standards with the understanding that some may require adjustment based on the material set, fabricator processes, and other design constraints. This chapter details high-frequency materials, copper foil types, metal core PCBs, and the benefits of embedded capacitance and resistor materials in multilayer PCBs.
The Cost-Benefit Analysis of Direct Metallization
10/21/2024 | Carmichael Gugliotti, MacDermid AlphaCarmichael Gugliotti of MacDermid Alpha discusses the innovative realm of direct metallization technology, its numerous applications, and significant advantages over traditional processes. Carmichael offers an in-depth look at how direct metallization, through developments such as Blackhole and Shadow, is revolutionizing PCB manufacturing by enhancing efficiency, sustainability, and cost-effectiveness. From its origins in the 1980s to its application in cutting-edge, high-density interconnects and its pivotal role in sustainability, this discussion sheds light on how direct metallization shapes the future of PCB manufacturing across various industries, including automotive, consumer electronics, and beyond.
Connect the Dots: Designing for Reality—Pattern Plating
10/16/2024 | Matt Stevenson -- Column: Connect the DotsIn the previous episode of I-Connect007’s On the Line with… podcast, we painted the picture of the outer layer imaging process. Now we are ready for pattern plating, where fabrication can get tricky. The board is now ready to receive the copper traces, pads, and other elements specified in the original CAD design. This article will lay out the pattern plating process and discuss constraints in the chemistries that must be properly managed to meet the customer's exacting manufacturing tolerances.
PCB007 Magazine October 2024: Alternate Metallization Processes
10/16/2024 | I-Connect007 Editorial TeamTraditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop taking us into new directions. In this issue of PCB007 Magazine, we examine the impact of alternate metallization methods giving a glimpse into how and when we will arrive at 'destination metallization'.
Partial HDI: A Complete Solution
10/10/2024 | I-Connect007 Editorial TeamWe recently spoke with IPC instructor Kris Moyer about partial HDI, a process that’s recently been growing in popularity. Partial HDI allows designers to escape route out from tight-pitch BGAs on one layer, where a mechanically drilled plated through-hole is not an option, while avoiding the complexity and expense of sequential lamination cycles. As Kris explains, this process doesn’t add much to the cost, and it’s fairly straightforward. But there are some competing signal integrity and fabrication requirements to contend with. We asked Kris to walk us through this process.
