Conformal Coating Spray

Adding Acrylic Conformal Coating to Your Printed Circuit Boards

Acrylic resins (AR) are single component materials. To specify, they are preformed acrylic polymers that are dissolved in a solvent to be applied to surfaces. One main benefit of using an Acrylic conformal coating service on your electronics is it provides an excellent barrier to moisture/humidity and have good fungus resistance. They also have minimal chemical resistance which makes it ideal for reworking and removability.

Acrylic Conformal Coating can be easily applied with a brush, sprayed or by dipping.  For smaller batch productions, such as prototyping, hand brushing is commonly.  For those large batch groups, spraying the coating on is best because it gives you an accurate control of coating. Dipping is achieved by placing the assembly into a vat of the coating.  This procedure is also well suited for small batches.

No matter where your electronic device is meant to be used, chances are high that there is at least one major atmospheric threat that can harm the delicate circuit boards within.  Conformal coatings made of acrylic resin (AR) are very popular choice because it protects printed circuit boards (PCBs) and other electronics from corrosion, dirt, dust, fungus, moisture, and thermal shocks.

Acrylic conformal coating currently makes up 80% of the market. The purpose of conformal coating is to protect the sensitive circuits in your device so that it can live longer and work better. What kind of threats does conformal coating protect against?

Moisture and Humidity

Moisture is a printed circuit board’s worst enemy. It can easily fry the circuit board, rendering it inoperable. Conformal coating may not be able to protect your device from a torrential downpour or a drop in the toilet, but it can resist humidity and condensation.

Dust

Dust can easily clog up a printed circuit board, especially due to electrostatic attraction. Conformal coating shields the inner workings of a circuit board from dust.

Heat and Cold

If your electronic device is meant to be used outside, then it will have to be able to withstand the sizzling highs and bone chilling lows of the environment. Conformal coating can protect against temperature extremes.

BGA inspection

How BGA Assembly Improves Performance in Modern Electronics

In the world of modern electronics, achieving optimal performance, reliability, and miniaturization is essential. Ball Grid Array (BGA) Assembly has emerged as a key technology in printed circuit board (PCB) manufacturing, enabling high-speed performance and superior durability. As industries continue to push for more compact and efficient devices, BGA Assembly plays a critical role in ensuring electronic components meet rigorous demands.

What Is BGA Assembly?

Processor with ball BGA pinsBGA (Ball Grid Array) is a surface-mount packaging technology that enhances electrical and thermal performance in PCBs. Unlike traditional dual in-line or quad flat packages, BGA uses an array of solder balls beneath the component rather than protruding pins. These solder balls establish electrical connections to the PCB, offering better heat dissipation, signal integrity, and mechanical stability.

Key Advantages of BGA Assembly

1. Higher Performance and Reliability

With shorter electrical pathways, BGA assembly improves signal transmission speeds and reduces interference. This design ensures lower inductance and resistance, making it ideal for high-frequency applications such as processors, graphics cards, and networking devices.

2. Better Heat Dissipation

Excessive heat is a major concern in compact electronic devices. The BGA package efficiently dissipates heat due to its larger contact area and direct connection to the PCB. This improved thermal performance extends the lifespan of components, reducing the risk of overheating failures.

3. Enhanced Miniaturization

Modern electronics demand smaller yet more powerful components. BGA Assembly allows for higher pin counts in a compact space, enabling manufacturers to fit more functionality into smaller devices. This is crucial in mobile phones, wearables, and high-performance computing systems.

4. Stronger Mechanical Connections

Unlike traditional leaded packages, BGA solder joints are less prone to mechanical stress and vibration-related failures. The spherical solder connections provide better adhesion, enhancing the overall durability of the PCB.

Applications of BGA Assembly in Modern Electronics

BGA technology is widely used across various industries, including:

  • Consumer Electronics – Smartphones, tablets, laptops, and gaming consoles rely on BGA packaging for their processors and memory chips.
  • Automotive Electronics – Advanced driver-assistance systems (ADAS) and infotainment systems benefit from BGA’s superior reliability in harsh conditions.
  • Medical Devices – Wearable health monitors and imaging equipment require compact and high-performance PCBs.
  • Telecommunications & Networking – Routers, 5G infrastructure, and high-speed networking equipment utilize BGA Assembly for improved signal integrity.

Ensuring Quality in BGA Assembly

BGA-boardsWhile BGA Assembly offers numerous benefits, ensuring flawless soldering and defect-free connections is crucial. Advanced techniques like X-ray inspection and reflow soldering help detect hidden defects and guarantee the highest level of precision.

At Board Assembly, we specialize in high-quality BGA Assembly with state-of-the-art manufacturing techniques. Whether you need custom PCB solutions, rework services, or advanced testing, our expert team ensures reliable and high-performance electronic assemblies.

Conformal Coating Service

Why apply conformal coating?

Printed Circuit Boards (PCB) is the core of everyday life as most electrical devices can not function without one. From everyday life to military and medical situations, a PCB must be able to withstand the wear and tear of time and other elements. Conformal coating is designed to protect Printed Circuit Board (PCB), and related equipment from their environment. Typically applied at 0.001 inches to 0.003 inches on the PCB. It is a protective nonconductive dielectric layer that is applied to the assembled printed circuit boards to protect the electronic product from damage due to contamination, salt spray, moisture, fungus, dust, and corrosion caused by the harsh or extreme environment.

Solder Mask on Printed Circuit BoardsACME PCB Assembly happens to offer three different kinds of conformal coating for our valuable customers. The acrylic conformal coating is a low viscosity coating that is cured through drying and isn’t too resistant to chemicals but hardens quickly. The Urethane conformal coating is also a low viscosity coating, however, is cured through crosslinking with strong resistances to chemicals. Silicone conformal coating is a very viscous coating that is applied through swirl technology with high chemical resistances.
