trailer tape length

trailer tape length | 3 June, 1999

Has anyone had a problem with the trailer tape length being too short and causing placement machine to stop for parts exhaust (SMT parts)? I realize the EIA spec. is set for this length but would like to know what issues you have had. Thanks

Hi DWR,

Have had that problem before. My solution was to purchase a tape splicer which enabled operators to join the old exhausted and new part reels without down time. Tape splicer is available through Top-Line. Hope this helps.

However, impossible for moveing table feeder machines (high speed). If feeder down time is an issue consider: 1. alternate pickup location 2. pre-load all heavy users. swap out when necessary

Generally, a feeder change should take less than 30 seconds. In my shop I have demonstrated feeder swap out techniques which take 10 seconds. Incidentally some machines have part counters and pre-warn sensors. Great if you got-em! Sorry if ya' don't.

Prepare for it.
