Protecting Your PCBs with Professional Conformal Coating Services

As electronic devices become smaller, more complex, and more widely used across harsh environments, protecting the internal circuitry becomes essential. Conformal coating is one of the most effective ways to safeguard printed circuit boards from moisture, corrosion, dust, vibration, and chemical exposure. At Board Assembly, our conformal coating services provide long-lasting environmental protection for PCBs used in industrial, medical, commercial, and aerospace applications.

Conformal coating is applied as a thin polymer layer—usually acrylic, silicone, epoxy, or polyurethane—designed to “conform” to the PCB’s shape and provide a protective barrier. Even a microns-thin coating can significantly extend the life of electronics, making it ideal for equipment exposed to fluctuating temperatures, humidity, chemicals, or outdoor environments.

conformal coating pcbOur process begins with thorough PCB cleaning, ensuring no contaminants interfere with adhesion. Depending on the project, we apply coatings using automated selective coating systems, brushing, spraying, or dipping. Complex assemblies with connectors, switches, or areas requiring masking are handled precisely, preventing material from covering critical contact points.

Different coating materials offer unique benefits. Acrylic coatings provide excellent moisture resistance and are easily repairable. Silicone coatings offer high-temperature stability and flexibility, making them ideal for automotive and aerospace electronics. Polyurethane coatings offer strong chemical and abrasion resistance. Epoxy coatings provide rigid, highly durable protection for severe industrial environments.

After application, boards are cured under controlled conditions. Our team verifies coating thickness, coverage, UV traceability, and masking accuracy to ensure full compliance with IPC-CC-830 standards. For assemblies requiring additional protection, conformal coating can be paired with potting and encapsulation services for deeper environmental sealing.

Conformal coating is especially valuable for industries such as renewable energy, automotive, marine, and industrial automation, where electronics face constant stress. By protecting circuits from corrosion and premature failure, companies reduce maintenance costs, extend equipment lifespan, and increase product reliability.

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.

electronic circuit board smtOnce the assembly begins, solder paste is applied using tightly controlled stencil printing methods. This ensures proper solder volume, which is critical for component adhesion and long-term performance. Our automated reflow ovens use multi-zone temperature profiling to ensure consistent solder joints across every PCB. Whether your project requires leaded or RoHS-compliant lead-free soldering, Board Assembly adheres to strict temperature controls that guarantee reliability.

Quality assurance is a core part of our SMT assembly workflow. Every PCB undergoes AOI inspection, verifying solder joints, polarity, bridging, component alignment, and placement accuracy. For boards with hidden joints like BGAs, we perform X-ray inspection to evaluate internal connections. These extra steps ensure long-term durability and minimize field failure risks.

Whether you are developing medical devices, IoT solutions, consumer products, industrial equipment, or aerospace electronics, our SMT assembly capabilities support a wide range of applications. Combined with our additional services—such as conformal coating, box build assembly, and potting & encapsulation—we offer complete turnkey solutions to support your entire production lifecycle.

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.

Before you invest in mass production, invest in certainty. Contact us today to schedule your trial run and protect your next big product.
