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.”

Connect the Dots: Stop Killing Your Yield—The Hidden Cost of Design Oversights
04/03/2025 | Matt Stevenson -- Column: Connect the DotsI’ve been in this industry long enough to recognize red flags in PCB designs. When designers send over PCBs that look great on the computer screen but have hidden flaws, it can lead to manufacturing problems. I have seen this happen too often: manufacturing delays, yield losses, and designers asking, “Why didn’t anyone tell me sooner?” Here’s the thing: Minor design improvements can greatly impact manufacturing yield, and design oversights can lead to expensive bottlenecks. Here’s how to find the hidden flaws in a design and avoid disaster.
