Optical inspection

Find faults easily using visual inspection of components and PCBs

Ersascope2 Optical BGA CSP QFP InspectionComplex electronic assemblies using advanced miniaturised component packages such as Ball Grid Array (BGA), Chip Scale Package (CSP), Quad Flat Pack / Quad Flat Pack No-Leads (QFP / QFN) and flip chips can be very difficult to diagnose when problems occur. This makes populated PCB inspection and testing highly challenging. That’s when advanced BGA and PCB inspection microscopes can make your life a whole lot easier.

Optical Measurement MicroscopeWe offer a range of different instruments to allow you to examine almost any aspect of a PCB or electronics assembly. Our Ersascope 2 uses a fibre optic stem and prism which bends the image by 90° so you can see sideways underneath a component already soldered onto the PCB. Our Hawk systems allow you either a high magnification stereo view of an assembly from almost any angle or the ability to measure things like copper plating thickness, fillet height or component dimensions to very high levels of accuracy.

All our visual inspection and measurement systems include video capture for reports, to allow comparison against previous samples or to track changes over time.

Optical inspection solutions

Inspect under BGAs, CSPs and QFNs using the Ersascope 2’s fibre optic stem and prism which bends the image by 90°. Its optical system enables inspections to take place in accordance with the IPC Inspection Standards (e.g. IPC J-Std and 610) for not only BGA, but also for the hidden, interior joints on surface mount devices and through-hole components. IPC and other industry experts acknowledge the importance of using such technology for inspection purposes.

In addition the system can be used with other lens systems to obtain close up photos of faults and anomalies. Included is a video camera connected to image processing software so that pictures can be stored, emailed or used as a reference source. Further software can assist with fault diagnosis and offers pictures of a range of typical faults and guidance for their rectification.

The Ersascope system enables defects to be found that may go undetected by other inspection methods; as such it offers the perfect complement to Electronics Yorkshire’s other scopes and X-ray system.

Check copper plating thickness, fillet height, component dimensions, etc, after microsectioning using our extremely accurate three-dimension, microscope-based, Hawk measurement system. This measures in three axes, to a resolution of 1 micron, with a wide range of advanced trigonometric functions and photographic capability. Magnification is from 50 times to 500 times.

The Hawk inspection system includes a video camera connected to image processing software so that pictures can be stored, emailed or used as a reference source.

From simple manual, single-feature operation to complex component part measurement, Vision’s Hawk offers a modular and flexible solution to meet a wide range of metrology requirements.

Accurate measurement of complex components is achieved using the high contrast, high resolution optical image, enabling enhanced surface definition for fast and simple measurement. Critical parts can be measured with confidence.


  • High repeatable accuracy, 3-axis (X, Y, Z) measurements
  • Optical image clearly defines edges, offering superb resolution and contrast
  • Powerful and intuitive microprocessor delivers simple, fast results
  • High precision measuring stage options
  • Camera image capture

The Hawk has both high precision and large capacity measuring stage options, making it ideal for high accuracy 3-axis measurement of tight tolerance, precision components, or difficult-to-view parts, such as low contrast plastics. Data processing is performed by a powerful multi-function microprocessor and has been designed with ease of operation in mind.

Optical equipment hire

Customers can use the equipment themselves at our Leeds facility. Time on the equipment can be hired by the hour or by the day, and will include training on the use of the equipment where required.


Optical investigation services

Alternatively, samples can be sent to the Electronics Yorkshire Technology Centre along with a clear description of the problem and the investigation needed, and our trained and skilled team will conduct the investigation on your behalf. If there is any uncertainty or if unexpected issues are discovered then the team will involve you by phone. Once the investigation is complete a report will be prepared, usually including images from the optical microscopes, which will be sent to you with the returned sample.


Hiring equipment

Call us for a personalised quotation for either time on our equipment or our investigation and report services. Discounts can also be offered for block bookings of equipment time or investigation services.

To arrange to hire equipment at Electronics Yorkshire, call 0800 610 1602 or email: info@electronicsyorkshire.org.uk; if you require Electronics Yorkshire to carry out work please contact us to check availability.
