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.
