Review pricing with current and outside suppliers to confirm you are paying the going rate.
“We don’t have the bandwidth to move business.”
That's what a printed circuit board buyer told me recently.
Let’s unpack that because it could be a shortsighted attitude.
When an EMS firm puts a PCB supplier on its AVL, it often asks only for pricing on new projects. When it comes to existing work, the response is often, “We don’t move boards once they are placed,” or, “we don’t have time to rebid those,” or, “it takes too much effort to move to another vendor.”
Even in the face of rising board costs, many buyers and procurement managers resist moving production away from suppliers they’ve used for years.
Will it be able to handle unforeseen events better than its predecessor?
Many are excited and working diligently toward enabling Factory (Industry or Tech) 4.0 to dramatically change their manufacturing and business environment, but maybe we should focus instead on Supply Chain 4.0, as that may change the manufacturing and business environment more – and not in a good way!
Businesses are currently operating within Supply Chain 3.0. Supply Chain 3.0 has taken decades to refine into a highly efficient, cost-effective, global supply chain. We know how we got here. Companies sought lower-cost skilled labor and a cost-friendly operating environment in which to build manufacturing facilities. As manufacturing shifted to these lower-cost areas, governments invested in infrastructure and education to attract ancillary businesses to invest there as well. Shipping and logistics improved thanks to the advent of containerships, larger aircraft, better roads and rail, and countries opening their borders to trade. The result was a global supply chain in which components and parts are made almost everywhere and transported “just in time” to assembly sites, before finished products are shipped to customers.
The proliferation of satellites and the "orbital economy" have exciting implications for Earth – but not without challenges.
An exciting market is developing 300km above Earth. New Space promises to revolutionize the delivery of internet services and create new opportunities for Earth observation that could help us improve crop yields, anticipate natural disasters, and manage our impact on the environment. There are also opportunities for manufacturing in space, taking advantage of microgravity to produce high-purity optical fibers and materials such as graphene, semiconductors, and superconductors. The in-space, or orbital, economy is already being debated.
This commercial development of New Space, which defines low Earth orbits (LEO) in the 300km-2000km altitude range, has become possible through the ongoing democratization of rocket and satellite technology over the last few years. Until recently, space missions were mostly the preserve of government-backed organizations. Today, however, the responsibility for launching satellites, as well as taking people and supplies to the International Space Station, has become substantially outsourced to private enterprises.
The size of satellites themselves is also becoming smaller, while supporting increasingly sophisticated capabilities, allowing greater value at lower cost. Small satellites, or SmallSats, are generally considered to be less than 180kg and, in fact, have been in use since NASA’s pre-Voyager missions of the early 1970s. The category is now more subdivided than ever and contains nanosatellites less than 10kg, picosatellites in the 0.1-1.0kg range, and femtosatellites of 10-100gm, although these limits are not rigidly defined. And, of course, there are CubeSats: the scalable proposal based on a standard 10 x 10 x 10cm basic building block. These are accessible to academic groups, including schools, as well as small commercial organizations.
Buy PCBs with your brain, not your heart.
“Pray for me. I buy circuit boards.”
That was a saying posted on the wall of a prospect I visited some 25 years ago. It’s funny, of course, but it also speaks to an unchanging truth about PCB buying: It’s often an emotional experience, especially when it comes to the bare board.
The PCB is the foundation of your products. It represents a good chunk – about 8 to 12% – of the cost of the bill of materials. While it is the first item needed to begin the assembly, it is usually the last item ordered. That alone can make buying boards stressful.
In my years selling boards and training companies how to buy PCBs, I’ve found it’s not a lack of knowledge about circuit boards that prevents buyers from leveraging their annual spend most efficiently; it’s misplaced loyalty or an aversion to risk.
Strategic conversations are key to sustaining existing business.
The current business environment is creating two significant challenges for mid-tier electronics manufacturing services companies at a strategic planning level. The first is program management workload. Material exceptions have become the norm, and program teams have become highly reactive to respond to changing program variables. Second, material constraints are causing OEMs to keep projects at their current suppliers and push out launch plans on new products. Taken together, planning for account growth beyond what is automatically going in the pipeline based on spikes in existing demand may not be a great use of program management time.
While it is unlikely a significant number of projects will be awarded in the short term, a lot of dynamics in the background make strategically assessing larger accounts an important activity right now. These include:
Given the current workload, the next challenge is determining how this type of analysis can fit into busy schedules. Strategically analyzing larger accounts relative to the dynamics mentioned doesn’t need huge effort.
When a program manager is prepared, discussions on ways to align solutions more closely with short- and long-term customer needs become easier. Analyzing accounts for opportunities is one way to counter the continuous bad news on the materials front. This type of analysis also helps identify potential vulnerabilities and either address the issue or build the assumption of eventual business loss into the forecast. In the current high-inventory business environment, it is always a good idea to understand which accounts have growth potential and which are quietly planning an exit.

A Robust Process for Account Acquisition in Electronics Manufacturing Services;Protecting modern-day, complex stencils requires a mechanism overhaul.
Ahh, understencil cleaning: a necessary – but challenging – aspect of the stencil printing process. I’ve certainly discussed cleaning in this space before, as the topic bears revisiting when things change. Now is one of those times. As a subprocess of the overall printing operation, understencil cleaning is employed at specific intervals – after “x” number of prints, as determined by the process and the product details – to clear the aperture area of solder paste. Left unchecked, there is a high probability any smear around the aperture will cause defects. This is especially true if printing anything close to microelectronics-level dimensions such as 0402s, fine-pitch BGAs, etc. With these conditions, the likelihood of bridging, solder balling or some form of defect is relatively high without a robust understencil cleaning regimen. To maintain a centered, high-yield process, thorough cleaning of the underside of the stencil between prints “as and when” is required. (There is no standard, “right” number.)
These facts have not changed in many years. What has changed are PCB designs, dimensions and electronics assemblers’ expectations. As we are all aware, miniaturization has driven stencil thicknesses down to an almost unbelievable 60µm for today’s mobile products. That’s thin! Modern-day stencils are highly complex tooling components with many tens – if not hundreds – of thousands of apertures cut into a paper-thin piece of stainless steel. The material is delicate, to say the least. With these actualities, it is time to reconsider the mechanisms for ensuring thorough, repeatable understencil cleaning that do not damage the stencil, introduce instability into the process or take too long to perform routine tasks. The industry should rethink the understencil cleaning system needed to manage current and future assembly realities. Aspects to consider include:
