Flexible HMLV PCBA Production for Complex Product Mixes

In today’s fast-paced innovation landscape, not every product requires mass production, but every product does demand quality, consistency, and agility. High mix, low volume (HMLV) production is essential for manufacturers building a diverse range of electronic assemblies in smaller quantities. Whether it’s a lineup of product variants, frequent design iterations, or low-demand specialized PCB assemblies, HMLV enables flexibility without sacrificing production standards.

Foxtronics EMS excels in managing complexity, change, and customization. From handling diverse BOMs and varying circuit board layouts to accommodating mixed-technology assembly, we streamline every stage of HMLV PCBA production. Our engineering and production teams are experienced in balancing short-run agility with rigorous quality control, ensuring each unit is built to spec, regardless of how unique the build is.

With the combined strength of our group companies—Accutron, OSDA, CCK Automations, and Argo EMS—we offer purpose-built facilities, robust traceability, and highly responsive PCBA production capabilities. Whether you’re building 10 units or 1,000 across multiple configurations, we keep your project moving efficiently with scalable, repeatable results.

High Mix, Low Volume (HMLV) Electronics Manufacturing

In electronics manufacturing, one size rarely fits all. Many manufacturers need to produce multiple configurations, limited-run prototypes, or specialized PCB assemblies without committing to high volumes.

High mix, low volume (HMLV) production meets this demand with flexibility, speed, and quality, making it a strategic advantage across industries.

HMLV advantages go far beyond flexibility

  • Faster design iterations
    Ideal for prototyping, pilot runs, and evolving product designs.
  • Reduced inventory risk
    Lower batch sizes minimize excess stock and improve responsiveness.
  • Support for complex builds
    Easily accommodates mixed-technology PCBs and specialized component requirements.
  • Adaptability to market shifts
    Helps OEMs respond to changing demand without retooling for mass production.
  • Lower NRE/tooling costs
    Eliminates the need for a high initial investment for low-quantity runs.
  • Stronger product differentiation
    Enables the creation of multiple variants tailored to niche markets.

Agile HMLV Production with Fast Changeovers

Manufacturing a wide mix of products in low volumes demands speed, adaptability, and precision. Our HMLV model support rapid changeovers, accommodating diverse product variants and small batches while ensuring consistent quality across every build.

Foxtronics EMS enables efficient high mix, low volume (HMLV) PCBA manufacturing with quick setup changeovers and real-time process adjustments. Our configurable work cells, smart programming, and advanced process controls ensure seamless transitions between builds, maintaining speed, flexibility, and quality across short runs and complex assemblies.

Fast Setup & Changeovers

Our production lines are optimized for quick transitions using modular fixtures, quick-change stencils, and flexible feeders, minimizing downtime between builds.

Mixed Technology Expertise (SMT + Through-Hole)

We run hybrid lines capable of handling assemblies that combine SMT and through-hole processes, making us ideal for varied BOMs and complex product configurations.

Efficient Component Management

Close coordination between our supply chain and production teams enables streamlined handling of multiple SKUs. Through centralized sourcing and VMI programs, we reduce delays and ensure part availability, even for short runs.

Quality Consistency Across Builds

Every unit, regardless of volume or variant, follows the same rigorous quality protocols, from first-article inspection (FAI) to Inline Automated Optical Inspection (AOI) and Functional Circuit Testing (FCT), ensuring consistent performance and full traceability.
