Doltronics will provide you with final assembly processing for small or large quantity
runs of your electronic product. Whether it is a custom PCB design, cable assembly, or a complete box build,
we can assemble and test your complete product. If desired, we can assemble, package
and ship the final product directly to your customers! Other clients require that their
sub-assemblies be shipped back to them for completion or final integration into their systems.
Either way we are here to support you in whatever manner you require.
Functional testing emulates actual product operation as designed. Functional tests are usually
conducted using calibrated test equipment or custom designed test fixtures. Test fixtures and test
plans can be provided by the customer or designed and devloped by Doltronics. Functional
testing is more effective than in-circuit testing, requires less tooling capital and is ideal for
smaller production runs.
In-circuit testing uses large capacity, generic test systems that are programmed to test selected
circuits or nodes on a printed circuit board. The tester is connected to the circuit board using
multiple test leads or a custom interface fixture. Software in the tester is programmed to measure
the expected characteristics of the circuitry between nodes. Failures are localized to a small
group of components between nodes.
In-circuit testing does not actually operate or functionally test the board. A board can pass
in-circuit testing and fail a functional test. In-circuit testing is designed to verify that
sub-circuitry meets individual specifications, and that the various interconnections are present.
In-circuit testing is very fast and suited for high volume work. Fixtures and software can be very
expensive and can cost from ten thousand to over one hundred thousand dollars.
