Manufacturing products and solutions that integrate electronic, electrical and mechanical systems is no easy task. Today’s design engineers must address multiple challenges, from integrating advanced core technologies in an optimum manner to managing complex supply chain issues. Using a comprehensive and coordinated design and development methodology goes a long way towards success in this disruptive marketplace. Here, Robert John Webber, European Applications Manager at specialist distributor for hi-rel connectors, Powell Electronics outlines 10 design tips and techniques to help remove unnecessary time pressures, avoid delays and increase time-to-market…
Team organization is key
The first task for any company or organization involved in the design, development and manufacture of devices and products is to establish a good team and set it up well. Typically, a project manager will lead a multidisciplinary team of engineers who possess the different specialist skills required, which might include software, electronic, mechanical or PCB design, manufacturing, test and quality assurance. Proper team organization is especially important when dealing with large teams or those with members working remotely.
A good analogy is a sports team. Regardless of the sport, the coach (think project manager) must help set up and coordinate a team of individuals with diverse skill sets, roles and responsibilities. They must keep these various talents – all of whom typically know their job well – on track to get the best out of them and deliver on the goals of the project. A team lacking the right mix of skills and talent – or with the wrong coach – will ultimately struggle.
Handling adversity
The last few years have been tough for everyone in industry, with multiple challenges making it more and more difficult to conduct business – from Brexit and US-China trade tensions to the COVID-19 pandemic and the Russia-Ukraine war. Even before these disruptions, manufacturing supply chains were under pressure from the demands of new technologies, ever-tighter development cycles and “just-in-time” production.
Some manufacturers suffered during the first months of the COVID pandemic because their processes weren’t flexible or resilient enough to handle the multiple disruptions presented, with some suppliers shutting down or refusing orders. Between workplace challenges, disrupted and dispersed workforces, and critical supply chain issues, some companies couldn’t maintain their business and either went into hibernation or folded.
You can’t build a house without bricks
Supply chain and procurement issues have risen to the top of the challenges a manufacturer must address, since even the best team can’t make a product without parts. One of the first questions you need to ask yourself is: when do you need the component stock? Do you need it for production, or for prototypes? When and how many are needed is a critical path, because while you can often get parts for a prototype, you may not be able to source those parts in volume quantities.
Understanding and managing lead times is an important element of manufacturing today. It is vital to ensure that the lead times needed for parts are properly accounted for in your development plan and timeline. Pre-COVID, you could usually count on parts being delivered in four to six weeks, but today some of these lead times can now be anything from 26 weeks to more than a year, depending on the component.
Extended delivery times (or worse, lack of availability) can derail a project. In a normal pre-COVID development flow, after the initial concept phase, sample parts might be used in prototype design and development, through to initial testing. Findings may then be integrated back into design and redevelopment, before formal testing is performed for application needs and standards compliance. At this stage, parts are ordered in bulk and production begins.
Today, each step should take procurement into consideration. The initial development should be done using a DFM (“design for manufacture”) methodology, with specifications based on part availability, as well as performance. Alternative parts options should already be in consideration at every step, especially for components known to be in tight supply. This is where it is vital to engage with a trusted development partner, with a healthy knowledge of and experience in supply chain management.
For example, a knowledgeable development partner can help you with parts selection by helping determine which parts can be substituted with little or no technical disadvantage. Keeping in close communication with your partner is also key, as you can communicate critical product deadlines throughout the development process. And it’s important to leverage your assets to keep your Bill of Materials (BoM) flexible in order to manage any changes in design.
10 tips for success
Powell maintains strong partnerships with a wide range of manufacturers and suppliers. But in the current climate of component shortages and lengthy lead times, the company has looked to expand its linecard with alternatives that can offer shorter lead times across various product categories. These include KEC for EMC interconnect backshells, Corning for specialist RF connectors, Hi-G for relays, Altran Magnetics for DC Contactors, and East Coast Microwave for custom RF cable assemblies. At the same time, the company has increased investment for in-demand items with existing partners, for instance in piece part stock with Amphenol and heatshrink boots with Glenair.
Looking forward
Surviving and thriving in today’s disruptive geopolitical and manufacturing environment requires effective management of both your team and the supply chain. Establishing the optimum team composition can help address issues before they start, ensuring the right people are in the right roles and are able to communicate effectively. In procurement, you should select components according to how they solve the design problem technically, how parts availability matches your various project milestone dates, and the manufacturability of the solution to be created. Working with a trusted and knowledgeable development partner can address all these factors, helping mitigate supply chain challenges and issues.
