AOI AUTOMATIC
OPTICAL INSPECTION
With an automated camera system, our printed circuit boards are checked component by component for the presence and quality of the soldering.
Certain defects only show up with this test. Some components are not immediately necessary for the primary functioning of a PCB. A functional test will not reveal the absence of such a component.
Of course, all printed circuit boards are visually checked after each step in the process, but especially if there are a large number of components on a printed circuit board, there is always the chance that a missing component or poor soldering is overlooked. The AOI scan identifies such omissions.
MDA MANUFACTURING
DEFECTS ANALYZES
Ready prints are checked using a pin bed with a large number of pin contacts. All contacts are managed, measured and analyzed at a rapid pace.
For almost all prints that we make in any series size, a specific pin bed is built and a program is written that analyzes the print. This test detects defective components or incorrect soldering.
FUNCTIONAL TEST
The functional test inspects whether the print actually does what it is intended for. A functional test can be performed by connecting to the connectors or via the pin bed. A program written for this purpose provides the printed circuit board with all possible signals and thus simulates actual operation. The outputs are checked to see whether the PCB actually emits the correct signals.
