Coplanarity Check with ChipControl

POSTED 05/09/2012

le quality is always a primary concern, it is even more important in the electronic production. It has an indispensable part in the production and controlling, as high quality measures at the industrial production of SMD components are essential for an economic production and the quality of the soldering result. An important criteria here is the coplanarity measurement, which gives the gap between the pins of a chip and the bearing surface. If this gap is too wide, the components can not be soldered accurately.

The software package ChipControl, which is based on the EyeVision software, was especially developed for the electronic industry and measures the correct coplanarity from components with pins as well as BGAs and therefore reduces the possibility of poor solder connections.

With the ChipControl command set a system has been developed, which can be integrated into the production process and which measures the coplanarity with high accuracy. Of course by using cameras with higher resolution, such as e.g. the EyeSpector smart cameras, the accuracy can be increased even further.
Additionally to the ChipControl command set the user also has the complete EyeVision software commands at his disposal. Therewith it is also possible - besides the measurement of the coplanarity - to detect the imprint on the Chip and determine the quality of the imprint. This novel design allows thereby the realisation of coplanarity measurement and optical character recognition with only one camera.

ChipControl offers special commands, so that the user only has to select the appropriate command, insert the parameters for the component, which he wants to inspect and the inspection will run autonomously on the testing facility.

For different component shapes, such as THT, SMD, QFT, SOT, BGA, SOIC, SOP, TSOP, TSSOP, the ChipControl command set is equipped perfectly and with the drag-and-drop programming function of the software the configuration can be carried out fast and easy.

The graphical commands for the different applications allows an easy parametrisation and the inspection program is ready for operation in only a few mouse clicks.
