RUSH PCB Unveils 10-Layer HDI Design and Manufacture Capabilities
May 1, 2018 | RUSH PCBEstimated reading time: 1 minute
Rush PCB Inc. now offers the design and manufacturing of multilayer HDI PCBs of 10 layers and more.
In making the announcement, CEO Akber Roy stated, “To achieve very high-density interconnection, designers at Rush PCB Inc. use what we know as Every Layer Interconnect (ELIC) technology. This is a method wherein each layer has its own copper-filled laser-drilled microvias. When stacked up, it provides the opportunity for dynamic connections between any two layers in the PCB. Not only does this offer an increased level of flexibility, but it also maximizes circuit density.”
Roy adds that RUSH designers have taken up the additional complex challenges in routing with via-in-pad (VIP) and by employing blind and buried vias. They laser-drill via holes and filled them with conductive copper paste.
“Before finalizing the design of multi-layer PCBs, our designers confirm the structure of the circuit board primarily based on the scale, physical size, and the requirements of electromagnetic compatibility (EMC)," said Roy. "Our designers use 10 layers of material, and in this stack-up design have decided that the placement of the innerlayer and the manner of distribution of different signals in these layers of the multilayer PCB. This careful planning and determination of the stack-up design beforehand save the user much time and effort in wiring and production later.”
Roy added, “Apart from very fine traces in the foil pattern, HDI requires sequential build-up (SBU) and microvias drilled with lasers. SBU technology is used to fabricate HDI boards. The HDI layers are usually built up from a traditionally manufactured double-sided core board or multilayer PCBs.”

Trouble in Your Tank: Implementing Direct Metallization in Advanced Substrate Packaging
09/15/2025 | Michael Carano -- Column: Trouble in Your TankDirect metallization systems based on conductive graphite are gaining popularity throughout the world. The environmental and productivity gains achievable with this process are outstanding. Direct metallization reduces the costs of compliance, waste treatment, and legal issues related to chemical exposure. A graphite-based direct plate system has been devised to address these needs.
Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
