Zero defect tolerance: HD-Camera enforced Tape & Reel ICs on PSV 7000 from Data I/O / V-Tek belt system


Damage, incorrect positioning of ICs or gapped blister belts cost industrial companies a lot of money annually. To ensure that customers of the Lindhorster EMS service provider, cps Programmier-Service GmbH, are protected against these risks and can expect only flawlessly equipped blister belts, the company has developed a special camera monitoring system for one of its belting machines.

 

The biggest challenges in the development were the testing of the ICs at the tape out within the belt pocket as well as the very limited space available. The result should be crisp images of the ICs before the heat seal of the belt pouches and so the camera station was installed directly in front of the tape out in a confined space. A further problem presented various foreign influences of the production hall, which threatened uniformly good imaging quality. As a result, the camera has been housed in a specially designed, opaque housing to ensure that camera technology and lens deliver high-resolution exposures with the highest measurement accuracy and a special lighting geometry and color. The combination of the camera with the technically advanced image processing software Vision Q.400 reliably detects components with an incorrect rotation position or damage to the pins. It was also essential that the camera station is coupled to the automatic belting device and triggers the immediate stop of the machine at the smallest noticeable, for example, a minute lint on the IC or component. For the subsequent visual inspection and removal of the defective IC, the camera housing can be pushed upwards with just one handgrip.

 

The heart of the system is the image processing system Vision Q.400 from Q.VITEC, which reliably handles stable test applications with up to 12 cameras at high speeds. The image processing software works with sophisticated algorithms and uses, among other things, geometry tests via contour comparisons and edge detection.

 

These functions ensure a perfect object recognition as well as position information and consequently the 100% storage tightness of absolutely undamaged pins. The length measurement of all PINs takes place with a tolerance of +/- 0.2 mm. A clear plus for the customers is that without exception all ICs have the same rotation position, no damage or material tears at the PINs and the complete blister belt is completely equipped, ie without empty pockets.

 

Cps developed the technically sophisticated system in close cooperation with the Wunstorfer companies PRAUTEC and its sister company Q.VITEC. With these companies, cps had partners who are specialized in the fields of mechanics, image processing and system integration and work together with renowned companies and universities worldwide.

 

In addition, this new camera system is compatible with tape-out machines from all manufacturers, such as V TEK or AMTEC.PRO, and can be easily installed. This new camera system can also be used with component programming units such as the PSV7000 from Data I / O or its predecessor versions for seamless quality assurance. This high-tech camera is marketed by cps-group in Lindhorst and PRAUTEC GmbH in Wunstorf.
