Ball Grid Array (BGA) Assembly: High-Density SMT Solutions from ACME PCB

A Ball Grid Array (BGA) is a type of Surface Mount Technology (SMT) packaging widely used for integrated circuits (ICs) that require a large number of interconnects. BGA packaging allows for a compact, high-density design, enabling the integration of more functions on a single chip module—making it an essential component in today’s modern electronics.

What Makes BGA Technology So Effective?

BGAInstead of using pins like traditional packages, a BGA uses an array of solder balls on the underside of the component. These balls create electrical connections during reflow soldering, improving both thermal conductivity and electrical performance. The result is a more robust, space-efficient, and reliable PCB assembly.

Key advantages of BGA packaging include:

  • Reduced board thickness – ideal for smartphones, tablets, and compact electronics

  • Enhanced mechanical durability – no fragile pins to bend or break

  • Improved thermal and electrical performance – essential for high-speed systems

  • Minimal maintenance requirements

  • Excellent compatibility with high-efficiency system designs

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

Ball Grid Array (BGA) Assembly Inspections

ACME PCB Assembly has provided (Ball Grid Array) BGA assembly, BGA rework, and BGA reballing service for Printed Circuit Boards since 1994. Having 20+ years experience behind us, we have extensive knowledge on how to assemble high quality (Ball Grid Array) BGAs. We have experience with everything from Micro BGAs to large size BGAs (55 mm), and ceramic BGAs to plastic BGAs.

BGA-boardsBGA assembly is a type of SMT process, which is used for Printed Circuit Boards. It allows for the customer to have more room for the PCB layout.  Ball Grid Array (BGA) packaging is a method for reducing package size and integrating a greater number of functions on a single chip module. BGA (Ball Grid Array) also replaces solder balls on the component underside for SMT mounting.

ACME PCB Assembly has a quality system for BGA assembly, the BGA will be received and inspected, and kept in a 40-degree Celsius storage with a 1% humility baking oven to make sure the BGA is good condition before assembly.  We inspect the BGA with a 3D X-ray, and make sure the void is under 25% of the total solder ball diameter. By using the X-Ray inspection process, we can eliminate the soldering problem on the board, such as solder bridging and insufficient ball melting.

We also add an additional layer inspection after the X-Ray inspection is done; using the ERSA scope to inspect the solder ball on the underside of the BGA so that we are sure the profile is correct; we assure you excellent quality during the BGA assembly process.  Some BGA assembly boards have VIA connect to the BGA pad, the best condition for that is have a VIA epoxy plug, and have the solder mask on the trace, so that solder is not wicked to the VIA and cause the solder to function insufficiently during the BGA assembly process.

By having ACME PCB Assembly do the BGA assembly prototype with or without Stencil will save you as the customer on assembly costs.
