PCB Inspection Services
Advanced 2D and 3D AOI and X-ray inspection for optimum performance
Detect anomalies early for peak PCB performance
Why PCB inspection matters
PCB inspection is a crucial part of our assembly process here at ETEMCO because it ensures that every board is built to perform reliably and meets quality standards. In addition to inspecting all boards, we offer testing on an as-needed basis to confirm proper functionality and long-term durability.
Ensure solder joint integrity & component accuracy and presence
Solder joints are the foundation of any PCB since they form the connections between components and the board. This, in turn, ensures proper electrical flow and mechanical stability.
Our inspection processes verify that all solder joints are strong, free from defects, and accurately formed for optimal performance.
Prevent costly failures
Even minor defects like poor solder joints, misaligned components, or cracks can lead to failure in the field and translate into costly repairs. Our thorough inspection techniques catch any issues early before they become larger problems so your boards are ready for real-world performance.
Verify electrical & mechanical functionality
Another part of our inspection process is measuring the functionality, both electrically and mechanically, of the board. In terms of electrical functionality, we’ll check the following:
- Components are placed and oriented correctly
- Detect shorts, opens, or missing parts
On the mechanical side, we’ll look for:
- Lead alignment, pin height, and proper insertion
- Physical defects like cracks and warping
Exceed industry standards
With every printed circuit board inspection and testing, we strive to go beyond industry requirements. A slew of industries rely on our comprehensive services to keep their products performing at their best.
When your business and product reputation are on the line, trust us to protect them with the highest standards of quality.
ETEMCO’s PCB inspection capabilities
As electronic components continue to get smaller and smaller and assemblies continue to become more complex, the ability of the human eye to visually inspect workmanship becomes more difficult. We have addressed this challenge by adding 2D and 3D Automated Optical Inspection (AOI) and X-Ray capabilities.
Tailored solutions
We’re fully equipped to handle projects of all scopes, delivering quality results every step of the way. We’ll evaluate your project and offer recommendations on what type of inspection makes sense, depending on its complexity.
If we determine that your product needs testing, we’ll carry it out with the same precision as our other services.
2D and 3D Automated optical inspection (AOI)
Achieve high-speed, high-precision verification
Our Mirtec MV-3L 2D AOI system features five 10 Megapixel cameras, multiple lighting options, laser-based co-planarity inspection, and leading edge algorithms.
The Mirtec MV-6 Omni 3D AOI system takes inspection to the next level, incorporating 12 projection moire 3D inspection technology, 8 phase coaxial color light, 18 mega pixal cameras, Optical Character Recognition, and ultra-high-resolution camera and lens for small component inspection. What does this mean for the customer? It means high reliability and high-quality printed circuit board assemblies.
X-ray inspection
Ensure solder joint integrity on bottom terminated devices (BGAs, QFNs, DFNs, LGAs)
The Scienscope X-Scope 1800, in standard or oblique view, allows our operators to inspect BGA soldering to verify IPC compliance. The machine's analysis tools evaluate solder joints for proper reflow, voiding, and circularity.
Common questions about PCB testing & inspection
What defects can AOI and X-ray inspection detect?
Our Automated Optical Inspection equipment can detect a wide range of defects including missing components, misaligned or lifted components, solder issues (bridges, shorts, insufficient/excessive solder), component polarity issues, wrong component, and foreign material. The cutting edge technology used by the AOI and X-ray equipment, allow for detection of defects that are very difficult or impossible to detect with the human eye.
Why is X-ray inspection necessary for BGA and QFN components?
X-ray inspection is necessary for BGA and QFN components, or most bottom terminated parts, because their solder joints are typically hidden beneath the package and are difficult to inspect using traditional visual methods. X-ray allows for non-destructive examination of these components to reveal any issues with the solder joints, ensuring the quality and integrity of the connections.
How does functional testing improve PCB reliability?
Regardless of the technology used to inspect the assembly, be it automated optical or visual inspection, ensuring the performance of the product with a functional test is optimal. The functional test will significantly reduce the probability of a defective assembly escape.
What industry standards does ETEMCO follow for PCB testing?
All of our assembly personnel are certified to IPA-A-610 by our in-house Certified IPC Trainer.
Can ETEMCO test PCBs that were manufactured in-house?
If a customer desires for their product to be tested as part of our services, ETEMCO’s production team will work with the customer to develop a functional test procedure to meet their requirements.
