High-Precision SMT Assembly Services for Reliable Electronics Manufacturing

Surface Mount Technology (SMT) has become the backbone of modern electronics manufacturing, enabling compact designs, higher component density, and superior electrical performance. At Board Assembly, we provide advanced SMT assembly services designed for prototype development, small-batch runs, and full-scale production. Our expertise, state-of-the-art equipment, and commitment to quality ensure your printed circuit boards meet the highest industry standards.

SMT assembly involves placing miniature components directly onto the PCB surface without the need for drilled holes. This allows for faster manufacturing, reduced board size, and the ability to integrate complex circuitry into smaller devices. At Board Assembly, our automated pick-and-place SMT machines provide exceptional accuracy, ensuring precise positioning of even the smallest components such as micro-BGAs, 01005 packages, and high-pin-count ICs.

For every project, we begin with a thorough design and documentation review to ensure manufacturability. Our engineering team evaluates your Gerber files, BOM, and assembly drawings to verify compatibility with our SMT processes. This helps prevent redesign costs, minimize delays, and ensure seamless transition from prototype to production.

Why Running a Trial Run First is Important in PCB Assembly

Do you have a new PCB idea that you’re excited to bring to life? Once your design is finalized and ready for production, it’s tempting to jump straight into a large manufacturing order—especially if you believe the product will sell quickly. But before committing to thousands of units, there’s a far more important question to ask: Will the PCB actually work the way you expect once produced in large quantities?

This is exactly why PCB Assembly strongly recommends performing a trial run before entering mass production. A trial run ensures that your design functions properly, that the build process is stable, and that potential problems are identified early—before they become costly and time-consuming.

What Is a Trial Run in PCB Manufacturing?

A trial run, also known as a pilot run or pre-production build, is essentially a mini mass-production cycle. Instead of producing all 6,000 units immediately, the trial run starts with a much smaller batch, typically around 200 units.

If that initial batch performs well, the order is scaled up to 1,000 units, allowing the engineering and manufacturing teams to:

  • Verify component integrity

  • Validate soldering processes

  • Confirm assembly consistency

  • Identify design or manufacturing flaws

  • Test the product under realistic conditions

Only after the 200- and 1,000-unit runs are successful do we move forward with the full order—such as the complete 6,000-piece production you originally planned.

This method reduces financial risk and ensures that your PCB performs flawlessly before mass production begins.

Why You Should Never Skip the Trial Run

Electronic circuit boardUnfortunately, many companies—especially those importing parts or outsourcing overseas—skip the trial run because they are pressed for time or eager to deliver products to their customers. However, bypassing this stage can result in:

  • Costly redesigns

  • Wasted materials

  • Delayed shipments

  • Failed PCBs

  • Customer dissatisfaction

  • Damage to your brand

A trial run acts as a quality gate, ensuring that your idea translates into a stable, functional, and manufacturable product. It provides the opportunity to confirm that the production line is operating correctly, that the PCB layout translates properly, and that the assembly team can reproduce your design consistently.

Trial Runs Protect Your Investment

Producing thousands of PCBs without first validating the process is a major financial risk. A trial run prevents:

  • Large-scale defects

  • Incorrect component placement

  • Soldering issues

  • Tolerance mismatches

  • Unforeseen board failures

Catching these issues early can save you tens of thousands of dollars and prevent product launch delays.

Start Smart—Test Before You Scale

Whether you’re launching your first PCB design or preparing to scale an existing one, a trial run is one of the most important early steps in the manufacturing process. PCB Assembly is here to guide you through each phase—from prototype to pilot run to full production—ensuring your product works the way it should.

PCB Fabrication and Assembly

Proud to Be a Lead-Free PCB Assembly Provider

There is a very good reason why the United States no longer allows lead in paint, plumbing, gasoline, toys, and many household products. Although lead is naturally occurring, it is also a highly toxic metal with serious health consequences. Research has linked lead exposure to behavior and learning difficulties, reduced IQ, slowed growth, anemia, cardiovascular problems, and, in extreme cases, coma or death. Children and pregnant women are especially vulnerable, and even minimal exposure can create long-term neurological and developmental harm.

For many years, lead was widely used in the electronics industry—particularly in soldering printed circuit boards (PCBs). Tin-lead solder was reliable, affordable, and easy to work with, which helped make it the long-standing industry standard. However, as global awareness of lead’s dangers increased, regulators and manufacturers began transitioning toward safer, more environmentally responsible lead-free alternatives.

At ACME PCB Assembly, we are proud to be part of this movement. Our full commitment to lead-free PCB assembly ensures a safer environment for employees and a safer end product for our customers. Switching to lead-free soldering is much more complex than simply changing materials. Lead-free solders melt at higher temperatures, which affects the entire assembly process, equipment requirements, and inspection standards.

Printed Circuit Board FabricationTo meet these demands, we invested in upgraded machinery, re-engineered our soldering and reflow processes, and strengthened temperature control systems to ensure long-term reliability. Just as important, our technicians underwent extensive retraining to understand the different properties, behaviors, and inspection details of lead-free solders. This comprehensive approach allows us to maintain exceptional quality while eliminating a major health and environmental hazard.

Although the transition required time, investment, and new expertise, it was absolutely worth it. Removing lead from our operations gives us a cleaner, healthier workplace and aligns our manufacturing processes with global standards such as RoHS (Restriction of Hazardous Substances). It also gives our customers confidence that their boards are produced using safe, compliant, and environmentally conscious materials.

Today, ACME PCB Assembly proudly operates as a fully lead-free PCB assembly provider, delivering high-quality, reliable PCBs for industries that demand safety, consistency, and performance.

Forward-thinking companies like Board Assembly are embracing eco-conscious manufacturing practices to reduce environmental impact while maintaining the highest quality standards.

Why Sustainability Matters More Than Ever

rework your pcbPCB production is traditionally resource-intensive. It requires large amounts of raw materials, water, energy, and chemical processing. Without proactive sustainability efforts, these processes can contribute to carbon emissions, hazardous waste, and long-term environmental damage. At the same time, many OEMs and end users now demand greener supply chains. Regulatory pressure is increasing, and corporate responsibility expectations are higher than ever. Sustainable PCB manufacturing is now essential to long-term business success and global environmental stewardship.

Key Sustainable Practices in Modern PCB Manufacturing

Material Optimization

One of the most important steps toward sustainability starts with material selection. Today’s manufacturers increasingly rely on lead-free solders, halogen-free laminates, and RoHS-compliant components to reduce toxic exposure and improve recyclability. In addition, unused material from fabrication runs is now more frequently recovered and reused to minimize waste.

Energy Efficiency

Energy consumption remains one of the largest contributors to a PCB manufacturer’s carbon footprint. In 2025, many facilities are modernizing with high-efficiency SMT equipment, LED lighting, and optimized production workflows. Some manufacturers are also incorporating renewable energy sources such as solar power, significantly lowering overall emissions.

Advanced Chemical Management

Etching, plating, and surface finishing require chemicals that must be handled responsibly. Sustainable facilities invest in closed-loop chemical recycling systems, solvent recovery programs, and state-of-the-art wastewater treatment to prevent harmful discharge into the environment. These systems protect both the environment and worker safety.

Design for Sustainability

Engineers now play a direct role in environmental impact reduction through design for sustainability (DfS). Smaller PCB layouts, HDI designs, and optimized trace routing reduce material usage while increasing electrical performance. Multi-functional boards reduce the need for multiple assemblies, helping lower both manufacturing waste and energy consumption.

Recycling and End-of-Life Recovery

Electronic waste is one of the fastest-growing waste streams in the world. Sustainable PCB manufacturers now support recycling programs that recover valuable metals such as gold, copper, and silver from old circuit boards. This circular economy approach reduces demand for new mining while keeping harmful materials out of landfills.

The Business Advantages of Sustainable Manufacturing

Sustainability is not only good for the environment—it also makes strong business sense. Companies that adopt green manufacturing practices benefit from:

  • Lower long-term operational costs

  • Reduced regulatory risk

  • Stronger brand reputation

  • Increased appeal to environmentally conscious customers

  • Improved supply chain stability

In today’s competitive electronics market, sustainability is now a differentiator that directly influences purchasing decisions.
