SOLUTION

Electronics Test Solutions

ESCATEC provides electronics test solutions for OEMs that need reliable PCBAs and assemblies from prototype through to production. Our test capability combines flying probe, in-circuit test, boundary scan, and functional test to help identify defects early, improve yield, and confirm products perform to specification before shipment.  

Test solutions with ESCATEC

Testing is an integral part of the manufacturing process, ensuring that defects are identified and resolved before a product reaches a customer. It is the only way to achieve optimal processes that result in products with as close to a zero percent failure rate as possible.

Our test solutions and expertise are especially relevant for companies that need fixtureless options for high-mix builds, on-site ICT for repeatable volume manufacture, or custom functional test and diagnostics integrated into the manufacturing process.

Key facts at a glance

  • Flying probe testing with fast programme creation direct from CAD files, no bed-of-nails fixture, suitable for low- to medium-volume, high-mix, and prototype applications.
  • In-circuit test (ICT) performed on-site, including analogue, digital, and vectorless tests, with fixtures and programmes also produced on-site.
  • Boundary scan using XTAG capabilities to debug and programme complex digital circuits, including structural fault location beneath BGAs without mechanical access.
  • Functional test solutions developed in-house by ESCATEC’s engineers or implemented from customer-supplied solutions, supported by engineering diagnostics.
  • Documented test plans and results to support troubleshooting and traceability, with controlled change management support for regulated programmes.

What test solutions does ESCATEC provide?

ESCATEC provides four core test solution types: flying-probe testing, in-circuit testing, boundary-scan testing, and functional testing. Together, these methods help identify faults earlier in the product lifecycle, reduce debug effort, and increase confidence that boards and assemblies meet their intended specifications before delivery. 

Flying probe testing

Flying probe testing is a strong option when batch sizes are small, board mix is high, or fixed-probe access is limited or impractical. Because it uses precision-movable probes to access test points, vias, pads, interconnections, and fine-pitch parts directly, it eliminates the need for dedicated fixturing while still achieving coverage similar to ICT.

  • Fast initial test programme creation direct from CAD files.
  • No bed-of-nails fixture required.
  • Suitable for easy inspection of PCB assemblies across low and medium volumes, as well as high-mix prototype work. 

In-circuit test (ICT)

ESCATEC offers on-site ICT covering analogue and digital tests, including vectorless tests. ICT fixtures and programmes are also produced on-site, meaning we own both the hardware and the test implementation for our customers.

  • Full on-site ICT capability.
  • Analogue, digital, and vectorless test options.
  • Valuable for slightly larger volumes.
  • Useful precursor to functional test to reduce debug time and improve functional test yield.

Boundary scan

Boundary scan is a rapid, non-intrusive test method for complex digital circuits. ESCATEC specifically leverages X-JTAG technology, paired with board-edge access, robust diagnostics, and the ability to identify structural faults beneath BGAs without mechanical access to the circuit.

  • Rapid debug and programming of complex digital circuits.
  • In-circuit levels of coverage and diagnostics for suitable boards.
  • Particularly useful where modern devices and bus technologies create extensive virtual test access.

Functional test

Functional testing is where ESCATEC moves from structural verification into proving that PCBs perform as intended in their real application environment. We can develop in-house functional test solutions or work with those supplied by our customers, and our extensive engineering diagnostics support compliance with customer-provided specifications.

  • Functional testing is used to verify board functionality against specification.
  • Solutions can be engineered by ESCATEC or implemented from customer-provided test methods.
  • Diagnostic support helps with troubleshooting and confident product release.

Which test method is right for your product, access, and volume?

The right test method depends on your product’s complexity, the level of access to the circuit, expected volume, and the diagnostic depth you need.

Flying-probe testing is a good choice for fixtureless flexibility and lower-volume/high-mix work; ICT is best for repeatable, higher-volume PCBAs; boundary-scan testing supports complex digital boards with limited physical access; and functional testing helps prove performance in the intended use case.

Whether you need a fixtureless flying probe, dedicated ICT fixtures and programmes, or a specific functional test setup, ESCATEC can support the test approach aligned to your product, volumes, and diagnostic requirements.

CASE STUDY

De-risking clinical readiness with integrated test solutions

CASE STUDY

De-risking clinical readiness with integrated test solutions

A Silicon Valley pharmaceutical company needed a device that met usability, sustainability, and manufacturing-readiness requirements while supporting FDA and ISO 13485 requirements. ESCATEC applied DfX, system integration, and precision control expertise to simplify the design and improve the user experience. The final design supported a smoother ramp-up toward an initial production phase.

Reducing risk throughout the manufacturing lifecycle

Testing works best when it is planned early, which is why ESCATEC’s testing capability spans the full manufacturing lifecycle, not just end-of-line activity.

By connecting the test strategy with DfX, prototyping, and NPI, ESCATEC helps customers identify faults sooner, avoid unnecessary rework, and industrialise products with greater confidence—reducing risk, cost, and time-to-market. 

Supporting quality, traceability, and regulated industries

For regulated and high-reliability programmes, ESCATEC supports documented testing, traceability, and controlled change management within a quality framework aligned to internationally recognised standards.

Our group certifications include ISO 9001, ISO 13485, ISO 14001, ISO 27001, and IATF 16949. We are also FDA-regulated and support ATEX projects in accordance with ISO/IEC 80079-34, while our manufacturing activities are carried out according to IPC-A-610 class 2 or class 3 levels.

What industries and product types does ESCATEC support?

ESCATEC supports OEMs operating in Industrial, Medical, and Transportation markets, with our test capability integrated into our broader PCBA, box build, mechatronics, and system-level manufacturing environments.

For Industrial sector customers, we offer high-mix, precision-engineered manufacturing, for Medical customers, ISO 13485-compliant manufacturing with traceability and proactive risk management, and for Transportation customers, ISO- and IATF-certified quality and scalable manufacturing support.

Test solutions FAQs

What electronics test options does ESCATEC provide?

ESCATEC provides flying probe, in-circuit test (ICT), boundary scan, and functional test solutions. For PCB assemblies and systems, test plans, limits, and results are documented to support troubleshooting and traceability. 

Can ESCATEC work with a customer’s existing functional test solution?

Yes. ESCATEC’s expert test engineers can develop in-house functional test solutions for you or work with customer-provided solutions. 

Do all test approaches require a dedicated fixture?

No. Flying probe, for example, eliminates the requirement for dedicated fixturing, while ICT fixtures and programmes are produced on-site across our global facilities where the method is required and appropriate. 

What are ESCATEC’s standard lead times for developing a test solution?

Timing will depend on the product and chosen method. For example, flying probe supports fast programme creation from CAD files, while ICT may involve on-site fixture and programme development, and functional test may be engineered by ESCATEC or provided by the customer, all resulting in varied testing lead times. Rest assured, ESCATEC’s end-to-end manufacturing support includes testing throughout the manufacturing process, resulting in shorter time-to-market. 

Can ESCATEC support regulated or high-reliability programmes?

Yes. The ESCATEC group holds various industry quality certifications, including ISO 9001, ISO 13485, ISO 14001, ISO 27001, and IATF 16949, suitable for highly-regulated Industrial, Medical, and Transportation programmes.
