RBB Systems experts in High-Mix, Low Volume
In the Electronics Manufacturing Services (EMS) industry, the term high-mix, low-volume (HMLV) refers to contract manufacturers (CMs) or original equipment manufacturers (OEMs) that frequently switch production between assemblies and processes. This contrasts sharply with low-mix, high-volume (LMHV) operations, where production runs can last weeks or even months between changeovers. HMLV shops are known for their agility, rapidly converting production lines to different assemblies—sometimes in a matter of hours or minutes—and doing so frequently, often several times a week or even within a single shift. LMHV, on the other hand, is a completely different beast, focusing on long, uninterrupted production runs..
Both business models are well-established in the industry, each serving its own purpose. However, for growing clients who face unpredictable demand and require a fast, flexible provider for their printed circuit board assemblies (PCBAs) and control panels, a third alternative has emerged: RBB.
RBB is like an HMLV shop on steroids. We build hundreds of unique assemblies annually, and it’s not uncommon for us to introduce multiple new assemblies in a single week. Rarely do we run a batch large enough to consume an entire shift of production time. But when we do, we “swarm to the need,” reconfiguring our workforce on the fly to keep things moving efficiently. No matter the size or complexity of the order, we take it in stride, ensuring that every client receives the same level of attention and care.
At RBB, we thrive on creatively responding to market uncertainties, rush orders, expedited requests, and pushouts. Our ability to adapt quickly and efficiently has earned us recognition, including Technology, Customer Service and Best Overall Awards for our company size from Circuit Assembly Magazine for the past three years. The more jobs we have in the hopper, the better—it allows us to solve client challenges daily, delivering solutions that go beyond the ordinary
Let’s take a closer look at how RBB compares to traditional HMLV and LMHV models:
Traditional HMLV Shops: Many of these operations view success as growing into an LMHV model or being absorbed by one. Their goal is often to outgrow the high-service business, seeing new opportunities as attractive only if they align with that path.
RBB: We pursue growth differently. Instead of aiming for high-volume production, we focus on serving a broader range of clients and assemblies, regardless of batch size. This approach provides a rare and much-needed value to the industry. Many clients and new applications cannot predict if or when they’ll reach a high-volume tipping point. They need a highly responsive and flexible CM partner to support them until that stage—and that’s where RBB excels.
This dynamic benefits everyone involved. OEM clients have more choices, with CMs specializing in areas that suit their unique needs. RBB stays true to its strengths, continuously improving its ability to handle diverse, low-volume projects. HMLV firms can build their customer base and grow with clients into higher-volume production. Meanwhile, LMHV businesses can focus on their core competencies, knowing that smaller customers are well cared for by providers like RBB. In this ecosystem, everybody wins.
