Happy’s DIY Solution to Chemical Control

I confess. I am a control nerd and highly analytical. My second degree is in EE control theory, and I see the world in terms of feedback loops and black boxes. Early in my career, I was volunteered for the technical programs for the California Circuits Association (CCA), which was created by my mentor Clyde Coombs. In discussions with fellow process engineers, it was clear that the chemical process controls that HP could afford and allow me to put in place were not able to be duplicated by much smaller PWB shops.

Chapter 1 Excerpt from the Book ‘Thermal Management: A Fabricator's Perspective’

Heat cannot be efficiently exchanged with stagnant air surrounding a hot device; however, it can be transferred away from the electronic component to the PCB using thermal vias. A thermal via is a good conductor of heat that runs between the top layer and bottom layer of the PCB, dissipating heat through simple conduction. In simple terms, thermal vias are plated holes located under, or electrically connected to, a surface-mounted heat source on a PCB that allows heat transfer through the hole.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

This past week, we published a variety of articles, interviews, and columns—and readers definitely made their favorites known. There was good news about hiring and staffing. (In case you were wondering, there are quite a few open positions in this industry right now.) We touched base with a pair of young engineers to get their thoughts on what it’s like for recent grads working in the PCB manufacturing community. We learned about a company’s new program that can help take some of the stress out of NPI. We also launched a new chapter in our “Just Ask” series, this time starring columnist Tara Dunn.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

Welcome to the Halloween issue of the I-Connect007 Top Five Editor’s Picks! This year’s Halloween lands on a doozy of a day. Astronomers among us will, undoubtedly, already have noticed that not only does the spooky holiday fall on a Saturday night, but it also falls exactly on a full moon—and a Blue Moon, at that! The last time a Halloween Blue Moon occurred in all time zones was in 1941. As if there weren’t enough “ghoulishness” already, 2020 delivers yet another rare occurrence.

Reducing Flux Splatter in Sensors and Camera Modules

With the increased use of electronics in new technology areas, flux formulations are being developed to address the new and existing requirements.

IPC Standards Development: Business Challenges and an Inside View

With increasing frequency, standardising the standards, such as ISO 9201, imposes certain rules that must be met to ensure “fair play” amongst the supply chain. There will be those familiar with hearing about “false positives/negatives” and “never trust the salesman,” so mitigating these is no easy task. However, there is the chance for each 5-30 Task Group to review industry requirements and set out the work program for the ensuing period. With that in mind, much of what follows is based on comments we learn about from our industry around the world, many of whom are not yet IPC members. Yes, this is a membership recruitment drive, unashamedly, as well as a search for volunteers willing to help create the standards of tomorrow.

How to Benefit From Robotic Soldering Processes

Webinars are in vogue! But in Pete Starkey's experience, the master of the technical webinar with many years’ experience of delivering first-rate events is Bob Willis—electronics assembly specialist, soldering expert, and provider of training and consultancy in electronics manufacture. Here, Pete recaps Bob’s presentation on the upcoming robotic soldering experience.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

Trade shows and technical conferences haven’t died; they’ve just moved online. The trade show season continues in virtual full force this week, and event coverage dominates the top five this week. Surprisingly, I don’t see events as this week’s theme. No, this week’s theme is “pundits.” We have Walt Custer’s industry outlook, seven experts on additive electronics, a designers conference keynote, and the IPC’s government relations expert. Don’t get me wrong: These folks are asked to speak to the industry for a good reason. They know their subject matter, and they present it skillfully. This week’s top five picks are worth reading.

This Month in PCB007 Magazine: The Acceleration or Deceleration of Change

Things have changed a lot in the last year, especially in the realm of technology. Just a year ago, 5G networks were on a smooth path to unquestioned rapid growth dominance. Today, while there has been much progress, and while there are some 5G capable devices available, it is far from universal. In some areas, such as near schools and residential areas, people were putting up roadblocks to 5G towers. Overall, there has been much progress, but the pace seems slower than was expected just a year ago. Some limitations are being identified, and there is already talk of 6G becoming available well before the end of the decade.

I-Connect007 Editor's Choice: Five Must-Reads for the Week

Most all the action this week involved the STMA International Conference and Exposition. I-Connect007’s Real Time with… video interviews generally led the way for views and clicks. In each item, the intent was to make things better in some fashion. Whether it was pivoting on trade show delivery, optimizing the metalization process in the fab, adding more AI to manufacturing capital equipment, unifying and furthering the concept of the digital twin concept, or responding to company growth by upgrading systems with the help the equipment manufacturers, all these news items speak to being adaptable and forward-thinking.

Stop Relating Trace Temperature to Current Density

Many design engineers and even many software suppliers make the significant mistake of equating changes in trace or via temperature with current density. This is incorrect at best and dangerous at worst. There is little if any correlation between temperature and current density. Current and trace dimensions (among other things) are the relevant variables, but current density is not. I hope by the end of this article you will see why. Here are four illustrations that will help you understand this.
