Routing High Density Inteconnects with Reliable Microvias-Cover

As electronics have become miniaturized, the technologies used to route interconnects have been pushed to their limits, and new modes of designing PCBs with high reliability have become standard. HDI PCBs take a particular approach to routing interconnects through multiple layers to ensure reliability during fabrication, assembly, and operation. The critical structure that enables this is microvias, which are prone to failure if not designed properly. Some simple design decisions will have a major impact on reliability and solvability in an HDI PCB layout.

In this e-book, readers will receive an initial look at the reasons microvia reliability has come into the spotlight and why HDI PCB designers put reliability first when routing through microvias. Covered topics include:

Warnings from the IPC regarding reliability of via structures in HDI PCBs
How to design microvias to ensure reliability
How to create a PCB stackup for a high density circuit board
How to set up design rules for layout and routing in HDI PCB design

Microvia Technology and Beyond for HDI Design

Microvia Technology and Beyond for HDI Design HDI PCBs, ultra-HDI, packaging, substrate-like PCBs, and highly advanced chip-on-board can all require microvia structures once electrical connections become very dense. In these designs, higher density chipsets and packages have driven the demand for more advanced fabrication capacity that can support microvias into advanced stackups. But in addition to microvias in standardized HDI stack ups, there are more advanced interconnects available for Read Article

HDI Quality and Acceptability Requirements

HDI Quality and Acceptability Requirements The very nature of microvias’ small size makes the acceptability criteria difficult to define. Most HDI Quality and Acceptability requirements are still OEM defined. The IPC has IPC-6016 as part of the IPC-6012, the generic QUALIFICATION AND PERFORMANCE SPECIFICATIONS (6010 SERIES). These specifications only cover the build-up HDI layers and not the core, which is covered by their own IPC specifications. IPC-6016 Qualification and Performance Read Article

Select the Right Microvia Aspect Ratio in Your HDI PCB

Select the Right Microvia Aspect Ratio in Your HDI PCB If you’re not familiar with PCB design or electronics in general, you probably wonder how newer electronics can pack so much functionality into progressively smaller devices. It takes more than just Moore’s Law, it takes creative PCB design methods to pack all that functionality into a single device. This gave birth to HDI design for densely packed circuit boards and small electronics, like smartphones and small form factor embedded systems. Vias Read Article
