KYZEN Comes Clean For SMTAI
In this interview, KYZEN Executive Vice President Tom Forsythe explains his company’s plans for the upcoming SMTA International show in Minneapolis, Minnesota, Oct. 31-Nov. 3. He discusses KYZEN’s latest aqueous cleaning chemistries and the company’s focus on providing reliable cleaning equipment and accurate data for customers. "This is the latest in that expanded envelope, with better economics, and better environmental health and safety," he says. "It's all part of this trend of always trying to be a better product and deliver better value.
How to Minimize Quoting Time and Increase Accuracy in EMS Production
New product introductions (NPIs) and customization have been increasing rapidly over the past few years—with the results that the already-small profit margins in electronics assembly are shrinking even further. Fifteen years ago, the PCB was the product. Today, most products are a system, with multiple PCBs, cables, and enclosures. Many manufacturers want to provide turn-key products that have multiple BOMs, making the assembly process even more complicated.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
We just wrapped up IPC APEX EXPO 2022, and I think it went better than anyone could have expected. I wasn’t sure the live show would actually take place.

2021: The Year of X = Xc – 1
Throughout 2021, I-Connect007 will focus on our theme, “X = Xc – 1,” in which we will explore continuous improvement in a practical way. Get talking about continuous improvement as a business method and the conversation often hinges around large programs and grand transformations. “Company culture” and “corporate transformation” are terms that often appear in these conversations. Often, it seems, continuous improvement is simply a huge undertaking.
Chapter 1 Excerpt: The Printed Circuit Assembler’s Guide to Process Validation
The original principle underlying the IPC’s ionic cleanliness requirement was that the mobility of surface ions, detectable from SIR measurements, would correlate to a maximum value of detectable ionic elements permissible on the circuit surface. The industry required a test that was both fast and accurate for process control. Thus, a simplified ion chromatograph that was able to detect ionic elements without differentiation was created.
Book Excerpt: The Printed Circuit Assembler’s Guide to Smart Data, Chapter 1
Accurate data is required to adjust processes and to ensure quality over time. This is difficult because not all data is in the same format, and not all sensors perform the same over time. How do you know what the best data to collect is and how to filter out the junk data from useful or smart data? This is not an easy task when the interfaces to data collection sources are complex, and they do not speak the same language, often requiring the vendor’s help to get data out of the machine and then spending time normalizing the data to turn it into something useful. This is a challenge for companies trying to set up a custom data collection system themselves.
Book Excerpt: The Printed Circuit Assembler’s Guide to Process Validation
It is assumed that readers are familiar with manufacturing electronic circuit assemblies in accordance with IPC-J-STD-001 or IEC 61189-1; both are titled “Requirements for Soldered Electrical and Electronic Assemblies.” In October 2018, IPC-J-STD-001 Revision G was amended and released with a new Section 8 of the document titled “Cleaning.” The change was primarily the removal of a “cleanliness” level of 1.56 mg/square cm of NaCl equivalence. This small change has great significance in relation to how companies ensure the electrochemical reliability of their products.

This Month in SMT007 Magazine: Test and Measurement in a Smart Factory
Nolan Johnson spoke with MIRTEC President Brian D’Amico about how the role of test and measurement equipment is changing in the smart factory and how shops can adjust to make use of the new technology. D’Amico shares this insight: “While approximately 90% of U.S. electronics manufacturers recognize the potential of Industry 4.0 to improve productivity, many are slow to adopt smart factory solutions within the manufacturing process.”
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.

Solder in PCBA: Can’t Live Without It... or Can We?
For most of its historical use in electronics, the solder alloy of choice was tin-lead, either an Sn60/Pb40 alloy or the Sn63/ Pb37 eutectic version of the tin-lead alloy. These two alloys were the workhorses of the industry. They were both well understood in terms of their processing and reliability—that is, until the advent of lead-free, a well-meaning but ill-conceived and poorly executed conversion, forced on the industry by the European Union in 2006.

Tips to Improve Soldering Tip Life and Reduce Cost
Whether in production, or repair and rework, the cost of soldering iron tips can be easily overlooked, but with today’s requirement for higher temperatures in lead-free solder applications, the consumption of tips has dramatically increased. This fact, combined with changes in tip design to meet the higher thermal load requirements, has also resulted in escalating tip costs, making tip care a high priority.
Towards a Data-Driven Cleaning Environment
Tom Forsythe, executive vice president at KYZEN, discusses the most critical challenges of the cleaning process, a new approach to testing the cleanliness of PCB assemblies, and how KYZEN is helping customers develop a more data-driven approach to cleaning.
In our conversations, many assemblers said that cleaning is not a value add, that their customers are getting nothing out of it. It also means an added process, and as such, an additional production cost. On top of that, no-clean fluxes have been in the industry for over 20 years now. But still, why clean?
Getting More with Cleaning

Improving SMT Yield and Reducing Defects: A Rauland Case Study
Ever-increasing demand for more complex boards that have higher densities of components means more challenges for SMT assembly operations and yields. Smaller component sizes and more densely packed PCBs lead to more powerful designs in much smaller product packages. These advancements have spurred a new set of challenges in building smaller and more complex assemblies.
PCB Pad Repair Techniques
There are a variety of reasons behind pads getting "lifted" completely or partially from the laminate of a PCB. Per the just revised IPC-A-610 Revision G, a defect for all three classes occurs when the land is lifted up one or more pad thicknesses. Lifted pads can occur when a device has been improperly removed or there is a manufacturing defect in the board construction. In any case, as with any repair, the ultimate decision on the ability to repair the pad lies with the customer.

Using Paste Flux for Rework
When using a hot air or IR rework system where the reflow cycle is mimicking the original SMT reflow profile, and when using flux for re-attachment, paste flux otherwise known as gel or tacky flux is the correct type of flux to use. Due to its high viscosity and tack properties, paste flux prevents components from being moved during hot-air reflow while being able to remain active for the complete time-temperature period.
Assembly Training and Education
Even if your PCB assembly process is optimized, there is always room for improvement. And no matter how successful your company has been in the past, you just can’t rest on your laurels. It is always in your best interest to strive towards a better operations model.
