Testing is one of the most crucial steps in electronics production. Its objective? To validate your product’s features. By drawing on the experience of our experts, we have developed a bespoke testing strategy to meet your needs.
Our testing strategy is based on 4 key criteria:
This information enables engineers at LACROIX Electronics to determine the testing resources needed to achieve your objectives.
At LACROIX Electronics we favour a collaborative relationship with our customers. This is why certain steps in the testing strategy can be carried out directly at home. This overall vision of comprehensive testing coverage combines customers and suppliers for optimal results.
In order to be ever more efficient and to monitor your requested quality level at the right price, LACROIX Electronics provides you with Design for Test (DFT) techniques. This expertise enables our specialists to integrate test-based constraints into your products’ development processes as early as possible in order to achieve the level of quality required during mass production. Thus, the test coverage you require is optimised and we are able to achieve the required quality level through optimisation.
DFT is also a necessary step before a partial or full automation step of the testing phase can be considered.

First, the “Solder Paste Inspection” (SPI) control checks the quality of the solder paste deposit in 3-D before component placement. Taking place alongside the crucial reflow stage, the Automatic Optical Inspection (AOI) control checks the placement and soldering quality of visible welds in accordance with occupational criteria.
These tests are automated and directly integrated into our “Surface-Mounted Components” (SMC) lines, which results in increased repeatability and efficiency, particularly in the case of large production volumes.
This second type of test ensures that the right components are installed in the right locations. Making the correction of potential errors simpler and less costly is a crucial step. Depending on your volumes, our experts will determine whether to use manual, semi-automatic or fully automated test equipment. The tests performed are generic, and may involve the following:
Once the product has been assembled, our team validates the functioning of the finished product. To do this, as part of our DfT: Design for Test approach, we design the tailor-made functional testing equipment in-house. This is all thanks to the work carried out in our test development centres located at the heart of our factories.
