Test Programming and Calibration
Process controls during manufacturing are critical to quality, but thorough testing is the ultimate validation of those processes. Testing PCBs, Assemblies, Cables, and Harnesses ensure the products you receive are right every time.
LPI provides numerous test capabilities through its extensive technical staff, team of manufacturing engineers, and partnership with Tecnova (LPI's sister engineering firm at our Gurnee campus).
Consider what Test Methods are best for your product...
ICT Testing
- PCB only testing
- Ensures the placement of components (values, orientation)
- Checks for shorts and opens in the board
- Does not apply power to board, test functionality,
or validate firmware
- Best when used for medium to high volume production
and for PCBs that will be functionally tested at a high level,
electro-mechanical assembly stage
Bed-of-Nails Functional Testing
- PCB only testing; custom build fixtures with and
without PC software/interface
- Applies power and validates PCB functionality 100%
- Best when complete testing is required before complicated
top-level assembly and where products ship directly to
end users
Bench Testing
- PCB, sub-assembly, or top-level assembly
- Simplified "ad-hoc” type fixture to test functionality
- For PCBs, fixture tooling is typically lower but testing
can be less reliable than a bed-of-nails fixture
- For assemblies, this may be the only method to fully
test a finished product before it ships to the end user.
Continuity Testing
- Cable Assembly and Harnesses
- Ensures continuity between connections
- Validates pin placement on connectors.

|  | Do your products have Programming
and Calibration requirements?
LPI can provide programming services for a wide array of Microprocessors, PICs, Flash Components, EEPROMs, and more using our in-house programmers, vendor sourced parts, or in-circuit adapters.
Additionally, LPI performs custom Calibration on numerous products for its customers. This includes documented procedures, calibration records, and traceability.
