Our ISO & IPC-compliant processes ensure high yield, reliability, and fast delivery from prototypes to volume production.
What Is BGA (Ball Grid Array) and Why It Matters for Your PCB?
A ball grid array (BGA) is a high-density surface-mount package that uses an array of solder balls on the underside of the component instead of traditional leads. It is widely used in advanced electronics such as processors, FPGAs, ASICs, memory, and high-speed communication devices where compact size and high I/O counts are required.
- Higher I/O density in a smaller footprint compared to QFP and other leaded packages.
- Improved electrical performance and signal integrity for high-speed, high-frequency designs.
- Better thermal performance and heat dissipation through the solder ball array.
- Increased mechanical reliability with controlled reflow and proper BGA PCB design.
Today, BGA PCB assemblies are standard in smartphones, networking equipment, automotive control units, and industrial automation. Choosing the right manufacturing partner ensures long-term reliability and consistent yield.

BGA PCB Manufacturing & Assembly Process
Our controlled end-to-end process ensures reliable BGA PCB solder joints and consistent production yield from DFM review to final inspection.
1. Engineering Review & DFM Check
We review Gerber, BOM, and placement files to optimize BGA pad design, fan-out, via-in-pad, and thermal layout for manufacturability and reliability.
2. HDI PCB Fabrication
Multilayer and HDI BGA PCB production with tight registration, microvias, and premium surface finishes for consistent solderability.
3. Solder Paste Printing & BGA Placement
High-precision stencil printing and automated placement with ±25 µm accuracy for fine-pitch devices.
4. Reflow Soldering
Customized thermal profiles prevent head-in-pillow, voids, and bridging for stable BGA PCB joints.
5. 100% X-Ray & AOI Inspection
Full X-ray inspection of hidden solder joints; 3D AOI verifies placement and visible solder quality.
6. Testing & Shipping
ICT, flying-probe, and functional testing available; ESD-safe packaging for global delivery.
BGA PCB Design & DFM Guidelines
Optimize your layout for BGA PCB assembly success with our proven design rules to avoid respins and assembly failures.
- Use NSMD pads for better solder joint reliability and consistent dimensions.
- Apply dog-bone fan-out for ≥0.65 mm pitch; via-in-pad for ≤0.4 mm ultra-fine pitch.
- Fill and cap vias on BGA pads to prevent solder wicking and voids.
- Maintain proper solder mask clearance to avoid bridging.
- Add thermal vias under high-power BGAs to improve heat dissipation.
- Keep clearance around BGAs for X-ray inspection and rework access.
BGA PCB Quality Control & Inspection
Quality is critical for BGA PCB because solder joints are hidden. Our inspection system eliminates latent defects.
100% X-Ray Inspection
Detects voids, opens, shorts, misalignment, and head-in-pillow defects invisible to optical tools.
3D AOI & Process Control
Validates component placement, polarity, and solder fillets; real-time reflow profile monitoring ensures consistency.
Electrical & Reliability Testing
ICT, flying-probe, functional test, burn-in, and environmental screening available for high-reliability BGA PCB projects.
