• How to use vision system to measure the key dimensions of carrier tape Online

Carrier tape drawing will help improve the accuracy of online measurement

The practical application project of vision system in industrial production focuses on the improvement of component online dimension measurement system and related algorithms.

The inspection object is the key dimension of IC auxiliary product carrier.

After the chip packaging and testing process is completed, each IC should be put into the carrier tape, sealed into a roll, and then applied to the PCB welding in the next stage. Large IC, such as CPU, will generally be put into the tray. The size of these tray is relatively large, and the big brother IC can be easily put in because of the large gap in the tray pocket.

Some small SMD components, such as resistors, capacitors, inductors and MOS tubes, are placed in the carrier and packaged in rolls. Usually, the dimensions of these components are accurately matched, otherwise it will greatly affect the coil quality of the product in the whole process stage and the application in the next stage

This is Junan company in China, supply kinds of carrier tape for customer all of the World
