EMC ANALYSIS
Adding Automated EMC Analysis to PCB Layout

There is a perception that EMC analysis during layout can be a time-consuming task that is challenging to set up and properly configure, with difficult-to-interpret results. But conducting EMC analysis at appropriate points prior to fabrication can mitigate the need for redesigns.

PLATING
Black Pad Revisited

Black pad is often the root cause of solderability issues. How do you differentiate it from other soldering defects?  And why should you care?

DfM
Guidelines for Improving PCB Design Manufacturability

Running PCB assembly lines without operators for an extended period of time is the holy grail of manufacturing. A look at the state-of-the-art technologies to put that goal within a robot’s reach.
by Ranko Vujosevic, Ph.D.

3D PRINTING
Elements of Additive Manufacturing for Functional Printed Electronics

The next leap for prototyping and additive manufacturing gets us closer to the “factory-in-a-box.” What elements are involved in this coming tsunami of additive manufacturing?

NTI-100
Automotive Driving Fabricator Gains

For fabricators whose major customers were Apple and Samsung, growth was hard to come by in 2016. But suppliers to the auto sector were revving up.

SALARY SURVEY
Among Designers, Compensation, Job Satisfaction on the Rise

If PCD&F’s latest data are any indication, more than half of today’s PCB designers plan to work in the field for no more than the next 10 years. The good news: Salaries are at their highest point yet – and so is job satisfaction.

PCB DESIGN
Methodology for Calculating Electrical Parameters of PCB Transmission Lines for High-Performance Computing Devices

Intensive research on problems related to multilayer PCB transmission line simulation hasn’t solved everything yet. Analysis and synthesis of lines in the subnanosecond time range, including special switched meander delay line structures, remain hurdles. There are, however, new hardware and software tools for debugging microprocessor systems and programs.

3D PRINTING
Improving PCB Design Methods to Complement 3D Printer Technology

3D printers are revolutionizing prototyping and disrupting age-old design methods. A new generation of EDA solutions supports 3D printing by providing unique design rules to support the specific conductive materials used and optimizing the data.

PARTS PLANNING
Optimizing Component Selection by Connecting the Designer to the Supply Chain

A new generation of connected design platforms, called engineering data management (EDM) systems, addresses issues of extended product development cycles by continually synchronizing supply-chain information with PCB design libraries, and alerting engineers to changes and conflicts.

DfX
PCB Designers Hold Smart Factories Ransom

Many companies have ended up “just living with” multiple, repeated PCB fabrication and assembly issues for years, regarding them as a given. If smart factories are to work, however, this has to change. Here’s how..

ADDITIVE PROCESSING
Savings and Efficiencies with Printed Silver Flexible Circuits

Historically, a designer’s only recourse as electronics packaging became denser was to incorporate flexible PCBs to route traces around 3D structures. Innovations in printing and component attach are seeing light, flexible printed silver circuitry in high-density applications where more costly traditional etched copper circuits were once exclusive.

DfM
Managing Rule Checks

The DfM validation challenge has increased over the past decade, thanks to the proliferation of new technologies such as flex boards, rigid-flex, chip-on-board, embedded components, and others. A new generation of design for manufacturing tools makes it possible to validate the design against design rules of all technologies and manufacturers that will be involved with the product in the early stages of the product development process.

SIMULATION
Algorithm for Constructing the Transient Process in a Meander Delay Line in PCBs

A graphic-analytical method for simulation of the transient process, as described by the authors, allows users to identify the basic mechanisms of pulse distortion in a meander delay line, and obtain the analytical dependencies for calculation of the efficient delay of signals at any predetermined level of receiver.

EMS TOP 50
Automotive and Automation

In a year of stalled outsourcing – even mighty Foxconn took a step back – two sectors continued to drive EMS forward. Who were 2016’s individual winners and losers?
