The Social Rewind for April 14, 2014

Are you subscribed to multiple social media networks like we are? Do you find it difficult it to keep up with all of the updates from the people you follow? Do you feel like you’re missing a lot of good information?

“The Social Rewind,” is a weekly blog digest of what we thought were the most interesting social media posts of the previous week. Q Source follows some really fascinating companies and individuals on Twitter, Facebook & Google+ and we want to share the best of what they have to say.

Leading off this week, Workrite Ergonomics shared this story that made us wonder about the relationship between office workers and inmates:


TE Connectivity’s series of Engineering Cheat Sheets come in very handy. This post focuses on Strength of Material:


Implanted electrical devices are changing people’s lives in a number of ways. Laboratory Equipment magazine’s post looks at their use with spinal cord injuries and paralysis:




Neil Armstrong’s one of the coolest nerdy engineers ever. In this post, Laughing Squid shares this animated video of Neil speaking to that subject:




WB Engineering’s post begs the question: Is a 3D-printed chocolate bust the ultimate selfie?:



And we close out this week’s column with our own post promoting another interesting guest blog by ACL Staticide’s Steve Allen: Why Clean "No Cleans?" Printed Circuit Board Flux Removal:



There you have it…another quick look at a few of last week’s most interesting social media posts. We hope you enjoyed this week’s Social Rewind. We’d love it if you shared other interesting blog posts with us. Keep on reading! We’re look forward to continuing The Social Rewind through 2014. This is an exciting year for us as we celebrate our 30th anniversary. Keep your eyes open for new features, promotions, interviews, and more. See you next week!

Why Clean "No Cleans?" Printed Circuit Board Flux Removal – Guest Blog

by Steve Allen, VP Marketing and Innovation, ACL Staticide

Steve Allen, our guest blogger from ACL, returns with this article about cleaning “no-clean” fluxes.

Today, nearly half of all printed circuit boards (PCBs) are assembled with no-clean solder paste. The development of no-clean solder paste was initiated to eliminate the need for further post-solder cleaning of circuit boards. Yet, many electronics assemblers are still struggling with the process of adequately and effectively removing no-clean flux materials.

No-clean fluxes are now the most popular fluxes to clean in electronics manufacturing. Most manufacturers have designed and dialed in their assembly lines to run no-clean paste. And, they only clean the boards they want to clean, not always the boards they perhaps need to clean. Additionally, the flux residues left behind by no-clean pastes are more difficult to remove from PCBs than other fluxes. Since they are formulated not to be cleaned, the residues from no-clean products can be left on the board in unwanted areas with detrimental effects on the PCB. That creates a cleaning challenge if you need to clean off a residue that was not designed to be removed.

No-clean flux and solder residue on the board depends on the amount of solids in the material, the type of gelling agents, and various activators in the flux. The fluxes in most of today's no-clean pastes contain up to 60% solids. The lower the total solids, the fewer residues on the board. No cleans, in theory, contain lower total solids so as not to need removal/cleaning. Following the reflow process, the flux leaves a small amount of residue around the various solder joints.

There are several reasons to remove no-clean flux residues from PCBs. Historically, no-clean fluxes were developed as tacky resins, which inherently coated and stuck to all surfaces. The residue would gradually build up on the test pins. Manufacturers began cleaning no-clean fluxes when problems emerged with in-circuit testing. The latest technologies of no cleans are improved and no longer tacky, but still can interfere with signal transmission in most instances.

Also, no-clean fluxes can inhibit proper adhesion of conformal coatings. No-clean flux residues can absorb moisture in process. In any further curing processes, the release of any moisture can cause the coating to be separated from the board and incomplete conformal adhesion can occur. This can allow corrosive materials, carbon dust build-up, or moisture to penetrate under the assembly and cause corrosion, signal transmission problems, and component failure.

Today, no-clean paste manufacturers are aware that end-users are cleaning no cleans from board surfaces. The type of flux chemistry chosen can have significant impact on the cleaning process. To effectively clean and remove no-clean solder pastes and no-clean flux residues, a polar solvent or a solution of water and saponifier is necessary. Most no-clean pastes require an organic saponifier for effective flux removal, but some can be cleaned with inorganic saponifiers. No-clean fluxes that contain halides leave the most residue and are easier to clean. However, halide-free no-clean fluxes produce less residue, yet are more difficult to remove. In general, no-clean fluxes can be extremely difficult to clean, particularly following any reflow processes, as they can be baked on and tough to remove.

It can be vitally important to resolve any issues with no-clean technologies and their subsequent cleaning challenges at the forefront of the device design process especially with high-reliability products such as avionics or medical devices. In applications where cleanliness is critical, it is important to consult cleaning experts like ACL for the most effective, board-safe cleaning technology.
