Low-Volume PCB Assembly Lots

The Highest Manufacturing Quality with Flexible Services

VSE icons-23

The success of an electronic product depends on manufacturing high-quality circuit boards built on time and within their budgets, and especially at the earliest point of manufacturing, quality trumps quantity. Original equipment manufacturers (OEMs) must meet schedule commitments and can’t afford delays from a vendor. Unfortunately, some PCB contract manufacturers (CMs) can’t fulfill orders as promised; we at VSE understand these concerns and aim to raise the bar on low-volume PCB assembly. We provide the highest levels of quality possible from a premier circuit board assembly facility while retaining the flexibility of a low-volume manufacturer.

Quality in Low-Volume PCB Assembly With Expert Engineering

The key to a successful low-volume build is understanding all the details before production begins to avoid unplanned disruptions. We meet with clients before manufacturing to understand project requirements. We’ll identify the design and layout constraints you have set and review critical milestone goals. Engineering staff then conducts a thorough evaluation of the design:

BOM Analysis:

  • Components at the end of their life cycle that are obsolete or not recommended for new designs (EOL/OBS/NRND).
  • Components that are cost-prohibitive or are unavailable for production.
  • Provide recommendations for alternative components or design changes.

Design for Manufacturability (DFM):

  • Devise component placement that complements an automated assembly process.
  • Accessibility of critical functional areas of the board for test and debugging.
  • Part locations to ensure that connectors, switches, and other interface devices are easily accessible.


  • Develop a test plan that will meet your project’s needs.
  • Enhance an existing test fixture or design a new one.
  • Optimize the test software for the circuit board.

Procurement Paves the Way For Seamless Production

The next step in low-volume PCB assembly is to procure the parts and materials necessary for production. This critical step requires quick purchasing to keep manufacturing on schedule. At VSE, our procurement team has years of experience optimizing procurement for both cost and availability while developing a robust structure and process to ensure that all of our customer’s projects meet stated deadlines:

  • Supplier network – Our procurement team has developed a vast network of component manufacturers, distributors, and brokers to stay on top of the PCB component supply chain.
  • Component research – Using part searching tools within the network, procurement specialists will find the best prices and availability of form, fit, and functional replacements.
  • Develop an open AVL – In collaboration with designers, the procurement team will develop an approved vendor list, giving us greater flexibility in sourcing parts.
