For automatic handler at customer site

Every handler has a set of guide wheels and a sealing base to adjust the cover tape's position and make the cover tape move smoothly before sealing. The cover tape's road map is shown below.

Guide reel and sealing base detail position on handler

When UCT runs on the handler as per the above road map, UCT moves intermittently because its PSA adhesive sticks to the surface of the guide wheel and sealing base.

This may result in:
1.
Debris Pollution: PSA adhesive remains on the surface of the guide wheels and sealing base plate

2.Poor sealing: PSA adhesive is damaged during indexing so sealing trace is intermittent

3."Open tape" and "broken tape" occurences

Action

1.Change the guide wheels that contact the UCT's adhesive directly with protuberant design wheel.
