84 DESIGN007 MAGAZINE I JUNE 2019 1 The Shaughnessy Report: Get Smart! E It sounds so perfect—"smart" manufacturing. That must be what we've needed all along! We've had enough of this "average intelligence" manufacturing. Yes, we've heard quite a bit of chatter about smart manufacturing over the past few years. Whatever "smart" means to you, ev - eryone involved in designing, fabricating, and assembling PCBs wants to get on board. 2 Automation and the Smart Factory: Introduction to Industry 4.0 E There's a lot of talk about au- tomation, but I find that there is very little available on au- tomation planning. This is one of my specialties. I start- ed by studying for an MSEE in control theory, which went well with my bachelor's degree in chemical en- gineering because I specialized in process con- trol and IC manufacturing. 3 Lightning Speed Laminates: How Copper Properties Impact PCB RF and High-speed Digital Performance E The circuit is a microstrip with a signal conductor on the top copper plane and a ground plane on the bot- tom of the circuit. Addi- tionally, the concept of skin depth and wave propagation should be considered. Skin depth is the depth within the cross-sectional area of the copper where the majority of the RF current resides and is dependent on frequency. 4 iCD Releases Impedance Goal-seeking Functionality E In-Circuit Design Pty Ltd (iCD), Australia has released a new target Impedance Goal Seeking Algorithm to add to the Stackup Planner func- tionality. This release will be rolled out to all iCD support customers as an update to their current software. Editor Picks from PCBDesign007 John Coonrod Happy Holden
