Celebrating our 35th year! Unidec provides support of cGMP validated equipment utilized in the pharmaceutical industry. We specialize in extending the lifecycle of validated equipment well beyond the typical OEM support cycle. We help keep you GAMP compliant and offer a host of reliability engineering services including repair, failure analysis, root cause failure analysis (RCFA) and corrective action preventative action (CAPA) support to help you analyze complex failures, extend the equipment life cycle and improve the performance of your production equipment and systems.

Circuit Failure Analysis

Unidec was founded in 1987 by John Fisher to satisfy a pent-up demand for electronics repair of industrial automation electronics. Unidec answered part of the repair need by quickly becoming a valuable supplier to hundreds of electronics manufacturers in a period of just three years. In the same period, Unidec developed repair for hundreds of electronic assemblies employed in the majority of through-hole and SMT equipment produced by Original Equipment Manufacturers (OEMs) such as Fuji, Philips and Universal Instruments.

Unidec offers repair on thousands of industrial controls and systems. Check out our product image library here. or the images here. We also offer evaluations and support for just about any industrial control system components – even when they are no longer supported by the manufacturer.

Unidec Lab Organization

While Unidec initially provided services direct to manufacturing facilities, Unidec also offered repair services direct to the OEMs. For example, Unidec helped both Philips and Fuji initially support their North American clients by becoming their primary repair source for many of the electronic components used on their equipment. Unidec tracks all documentation, repair processes, test setups, and electronic parts.

Over 50,000 Electronic Parts on-hand

Unidec continues today with support agreements to equipment makers and third-party firms to help service and source key-products. Unidec currently supports over 2,800 industrial and commercial electronic controls and systems and typically adds one new service offering each week.

Test Technologies

Unidec over the past twenty years has created and leveraged a new technology which combines functional test (FT) with traditional in-circuit-test (ICT) to solve a difficult problem when testing and repairing circuit boards. Unidec’s Tacit Expert System leverages rapid test development (RTD) software libraries to create deterministic functional diagnostic tests. In other words, functional test software that is re-usable between various products.


Our Tacit ES system leverages In-Circuit-Test (ICT) vector capture and compare heuristics to find subtle circuit failures other ICT equipment often miss, This proprietary Tacit-ES technology is similar to today’s antivirus software that looks at patterns of data (heuristics) that are correct during a board’s function. Then, the combination of knowledge base information and expert knowledge learned in the process helps determine which device is causing a functional test to fail. Our Tacit-ES proprietary technology is designed to take the guesswork out of circuit board test and troubleshooting. The technology also dramatically improves quality by looking at the heuristic “finger-print” of each device during the functional test and this feature dramatically reduces the likelihood of a faulty circuit board from being put back into service.

Microprocessor Emulator

Unidec’s also excels at Built-In-Self-Test (BIST) techniques as part of any comprehensive functional test methodology. Unidec has decades of experience in developing on-board assembly language based diagnostic utilities that are designed to run on the target processor of an embedded system.

Microprocessor Emulator Socket

We designed our BIST diagnostics to test a board or systems functionality at full processor speed which helps ensure that the unit will be fully functional when installed in the field. Unidec will develop BIST diagnostics in addition to other functional and in circuit testing whenever necessary.

How we do it:

When our product support is developed, we design a functional test strategy, specific test functionality, build test interfaces and harnesses, we even reverse engineer when necessary. The support package is properly documented, the hardware setups are created, and high failure rate electrical parts are pre-ordered. We then organize all of our projects, test setups, documentation and spare parts in our custom storage system and enter information into our database system to keep track of the complexity.
