Quality by Design
The design team’s files and the accompanying documentation is the real-world implementation plan to turn the OEM’s concepts and marketing research into a viable, physical, competitive product. Unless manufacturing defies the build instructions from the designers, the product will only be as manufacturable as the design files themselves.

Here's a recap of the events and presentations at the symposium.
IPC’s PCB Tech Trends Study Highlights Issues Impacting Fabricators
The 2018 survey results indicated the need for speed and low loss as critical functions of the materials chosen. This is the digital age, and with the Internet of Things, virtual and augmented reality, vehicle-to-vehicle communication, etc., the need for low-loss and ultra-low-loss materials continues to grow as a percentage of circuit boards fabricated.

Are Regional Differences in PCB Technology as Great as We Think?
We keep hearing that Asia is all consumer and automotive electronics and North America and Europe are all high reliability/long life. The findings in IPC’s PCB Technology Trends 2018 study show that these regions are not as different as expected, and the differences we do see are interesting.
XNC Format: Gerber Takes Data Into the Future
The problem is that so many NC files are of deplorable quality because the NC format was never designed as a data transfer format. It has always been a machine driver and contains all sorts of information that a drilling machine needs, but that is irrelevant and confusing for data exchange.
Technically Appropriate Material Choices are Key to Design Success
Materials are no longer a passive part of the design; they play an active role in the manufacturability, reliability, and speed of a PCB. I-Connect007’s Nolan Johnson and Mike Creeden, founder of San Diego PCB Design, discuss several key characteristics that designers should consider in their material selection process.
Learning to Be More Flexible: Case Studies on Improving FPC Design
As miniaturization requirements force manufacturers to pack more functionality into ever-smaller packages, it becomes more difficult to conform to IPC construction recommendations. Achieving robust FPCs requires frequent, iterative interaction internally among the mechanical, electrical, and PCB design teams, as well as with the fabricators and assemblers. The sooner in the design cycle you can engage the supplier and assembler, the better.
Vertical Conductive Structures, Part 1: Rethinking Sequential Lamination
Sequential lamination, as it is used today in high density interconnect (HDI) and derivative technologies, is constrained by the fact that one cannot plate a blind hole deeper than the diameter of the hole. A larger hole allows processes to plate deeper. In fact, this manufacturing constraint has made it a challenge even to reliably plate and process blind holes up to a 1:1 aspect ratio.
Averatek on the Future of Additive and Semi-additive Processing

The Quest for Perfect Design Data Packages
There’s an ongoing problem in the PCB industry: fabrication shops are receiving incomplete or inadequate design data packages, leaving manufacturers scrambling to fill in the blanks. For a quick-turn prototype shop like Washington-based Prototron, with over 5,000 customers and up to 60% of orders coming from new customers each month, that can add up to a lot of wasted time and effort just in the quoting stage. Dave Ryder, Prototron president, and Mark Thompson, engineering support, delve into this continuing issue and more.
