PCB Design Best Practices: Tips from the Experts

PCB Assembly service in Los AngelesPrinted Circuit Boards (PCBs) are the backbone of modern electronic devices. From smartphones to industrial machinery, PCBs ensure that electrical components are connected and function properly. Whether you’re developing a small prototype or scaling up production, good PCB design practices are critical to success. Here are some expert tips to help you design efficient, high-quality PCBs.

1. Plan Your Layout Strategically

The layout of your PCB can make or break your design. Start by organizing components based on their function and proximity to each other. Grouping similar components minimizes the length of signal paths, which helps reduce electromagnetic interference (EMI) and improves overall signal integrity. Additionally, ensure that your printed circuit boards have enough space to accommodate each component without overcrowding.

Visit our PCB Layout Services to learn how we can assist with optimizing your design layout.

2. Prioritize Signal Integrity

Signal integrity is essential to the reliable performance of your circuit. To maintain high signal quality, route sensitive traces such as clock signals away from high-current traces. Consider using differential pairs for high-speed signals to minimize noise. Proper grounding and shielding techniques can also help reduce noise and improve signal integrity.

Discover how our PCB Assembly Services can help ensure the highest levels of signal integrity in your projects.

3. Optimize Power Distribution

Power distribution is often overlooked but is crucial for maintaining the stability of your PCB. Design a robust power distribution network with ample decoupling capacitors placed near power pins to minimize voltage fluctuations. Use wide traces for power and ground planes to reduce resistance and ensure reliable power delivery.

Learn more about our PCB Power Distribution Solutions that can help you build a reliable power network for your design.

4. Minimize Crosstalk

Crosstalk occurs when signals on nearby traces interfere with each other, leading to performance issues or even complete system failure. To minimize crosstalk, increase the spacing between parallel signal traces or route them perpendicularly across different layers. You can also add ground planes between signal layers to shield traces from interference.

For more expert insights on reducing crosstalk, check out our PCB Expert Advice.

5. Use Design for Manufacturability (DFM) Principles

DFM ensures that your PCB design is optimized for easy and cost-effective manufacturing. This involves following industry standards for trace widths, hole sizes, and pad dimensions, as well as minimizing the use of unnecessary vias. Working closely with your manufacturer during the design phase will help avoid costly errors and delays later in production.

For expert guidance on DFM, contact our team at Board Assembly.

6. Test and Simulate Early and Often

Testing is a critical part of the PCB design process. Use simulation tools to verify the performance of your PCB design before manufacturing. Early testing helps identify potential issues such as signal interference, power integrity problems, or thermal issues, allowing you to make adjustments without incurring costly rework.

Cable Harness Assembly

ACME PCB Assembly Offers Cable Harness Services

Cable Assemblies include one or more wires that run together in a single sleeve with a connector or plug on each end.  Cable assemblies could be groups of wires or cables bundled together.  They are wrapped in a thermoplastic or vinyl sleeve, cable assemblies are ideal for directing groups of wires and cables around obstacles.

Cable assemblies are designed to perform specific functions that is determined by the plugs, terminals, and connectors that are found on each end.  They are used in most electronic applications, everything from flat panel displays to the automotive electronic system to integrated cockpit systems to simple LED lighted clothing, costumes and accessories.

What Do You Use Cable Assemblies For?

Cable assemblies intersect or interconnect different circuits or electrical paths, so they work together to transmit signals or power.  They usually only have two ends to connect point A to point B.

Ethernet Cable HarnessFor example, ethernet cable assemblies are designed to provide service supporting bandwidth speeds up to 10 Gigabit Ethernet, such as large data centers, military field units, and medical facilities.  For those applications that require a lightweight, smaller assembly that can transmit clearly and rapidly over great distances, support greater bandwidths, with high voltage isolation, then fiber optic cable assemblies would meet those needs.  A few of the industries that utilize fiber optic cable assemblies, include aerospace, automotive, industrial, medical, and military applications.

Cable harnesses are more complex in nature and may require different machinery and tools to be consistent with production. Creating slits and windows in cables demand specialized equipment to handle the various conductors within the insulation.  We

Conformal Coating Spray

The Growing Importance of Conformal Coating in PCB Protection

Printed Circuit Boards (PCBs) are at the heart of modern electronics—but as devices become smaller, more powerful, and more widely used in harsh environments, protecting these sensitive components has become more critical than ever. That’s where conformal coating in PCB protection steps in as a game-changer.

Whether it’s a consumer product exposed to daily wear or a military-grade device deployed in extreme climates, PCBs need an added layer of protection. Conformal coating provides exactly that: a thin, durable film that safeguards electronics from moisture, dust, chemicals, and temperature extremes without compromising performance or size.

Solder Mask on Printed Circuit BoardsWhat Is Conformal Coating?

conformal coating maskingconformal coating maskingConformal coating is a protective chemical layer applied to the surface of a PCB to create a barrier against environmental contaminants. It’s “conformal” because it conforms to the shape of the board and its components, coating even hard-to-reach areas without needing bulky enclosures.

At Board Assembly, we apply conformal coatings using precise, industry-approved techniques that ensure full coverage without interfering with the function or accessibility of electronic parts.

Why Is Conformal Coating Becoming More Important?

As electronics continue to expand into sectors like automotive, aerospace, defense, and IoT devices, the environments these PCBs operate in are becoming more unpredictable and challenging.

Here are a few key reasons conformal coating is gaining traction:

  • Moisture & Corrosion Resistance: In humid or marine environments, moisture can cause corrosion, short-circuits, and long-term failure. Conformal coatings seal off the PCB surface, keeping moisture at bay.

  • Chemical Protection: In industrial settings, exposure to cleaning agents, fuels, or harsh chemicals is common. A conformal coating acts as a shield, preventing chemical damage.

  • Dust & Debris Protection: For electronics in outdoor or manufacturing environments, dust accumulation can hinder performance. Coatings protect against particulate buildup.

  • Extended Product Life: By protecting the PCB from environmental damage, conformal coatings significantly increase product reliability and longevity—essential for industries where equipment failure is not an option.

Applications Across Industries

From automotive control units to aerospace avionics, and from wearable medical devices to outdoor smart home systems, conformal coating in PCB protection is now a standard best practice in many industries. As miniaturization and high-performance demands increase, protective coatings are no longer optional—they’re essential.

Why Work With Board Assembly?

At Board Assembly, we offer advanced PCB assembly solutions that include precision-applied conformal coatings to ensure your product performs reliably in any environment. Whether you need protection from moisture, vibration, chemicals, or dust, our team ensures your PCB is ready for real-world conditions.
