  • Dynamic EMS Goes from DFM to MFD


    The low-volume environment is challenging, all the industry processes, tools, equipment and even the materials are targeted at the high-volume market. Choosing the correct processes is critical and getting it wrong can be costly.

    For example, when you look at higher volume markets, machine set-ups use up sample cards to adjust parameters and optimise the line for the best yield. Sample sizes vary, from ten or so to in some cases running a few hundred. 

    Low-volume producers, however, have to develop methods and processes that best match a particular product with virtually no sample cards. From a manufacturer’s standpoint, being given a small handful of cards for manufacture demands a special team of folks with extensive experience and knowledge to steer a new unknown product through the processes with no losses. The ability to do this well takes an exceptional set of skills.

    We all know about Design for Manufacture (DFM), but what happens when you observe designs that will impact producibility? Do you produce, then rework, then ask for a redesign that will delay the product? Or do you accommodate these design-limiting issues through innovative tools and methods that you develop in-house to mitigate these yield-impacting designs?

    At Dynamic EMS we understand that no two customers are the same.  Their products, their supply chains and their markets all differ.  This is why Dynamic EMS offers tailor-made, customised electronics manufacturing services to customers with complex, highly diversified businesses.

    Dynamic EMS are constantly innovating different methods and tools to make our processes as robust and efficient as possible. Once we identify issues through our DFM, we use a process we call Manufacture for Design (MFD). MFD is Dynamic’s unique ability, based upon years of experience, to utilise tools and methods that foresee and mitigate potential DFM issues. We are constantly evolving these tools, constantly challenging ourselves to serve our customers better. 

    Here are a few examples of Dynamic’s MFD in action:

    Stencil design
    Stencil design is a valuable area in MFD – we have managed to overcome some awkward issues with clever paste patterns including solder float and voiding issues.

    Placement also plays a role – sometimes, to accommodate some connector issues or poor pad design, we offset placement.

    With reflow, we strive to keep the profile as low as practical, matching the peak package temperatures to minimise flux exhaustion, especially when we have to extend the soak to minimise voiding.


     We also try to avoid unplanned maintenance, but even then sometimes the machines play up. For high-mix product lines, keeping on top of machine maintenance is a top priority.

     Special processes
    Then there are the special processes like conformal coating, or fixtures requiring certain fasteners or batteries.  Final box builds can also bring new challenges and solutions.

    The opportunity for surprises sneaking up and biting you is always there – we have a watch-out-for list, which in the high-mix environment is quite extensive. This is why we always recommend that our clients run the designs past us so we can capture the “watch out fors” before they hit the shop floor.

    At Dynamic EMS, we see ourselves as solution architects who are constantly challenged, if we don’t have an off-the-shelf solution that fits our customers’ needs, we will design and build our own. Since we are our own management team and not confined by corporate restrictions, we can do exactly that.

    We are the solution architects for your low-volume, high-mix environment. With over 25 years of manufacturing expertise, we deliver value to our end customers because we offer electronics outsourcing right through to a finished goods model, delivered with an experienced, innovative perspective that considers all the elements of a new product’s use. From design to distribution, we enable our customers to be more competitive by bringing innovative solutions to market faster, with a commitment to quality in everything we do.
