No help to Haim, but I'ld like to find a reliable method of splicing leader
tape onto reels. Our manufacturing is done in very small batches, and
attrition at the start of a run can amount to 1100%. We're trying to get
our assembly house to remember to leave some empty tape at the beginning of
the reel after a run, but they often forget and cut off all empty tape
resulting in another dose of attrition next time.
Any news of a means of attaching leader tape would be most welcome.

Hi all,
We supply components in Tape & Reel (typically in quantities of 500 parts
per Reel), and often we are left with meters of Carrier Tape at the end of
a
roll, not long enough for a full quantity Reel.
Another $B!H (Bproblem $B!I (B we occasionally have is when a customer orders a non
standard quantity in Tape & Reel, say 200 parts instead of the standard 500
parts per reel. Currently, to supply this 200 piece Reel, we will either
cut 200 pieces off a full 500 piece Reel, or take remnants of previously
cut
reels and Re-Tape the 200 pieces on new Carrier Tape. When feasible, we
will give the customer a usable Leader and Trailer for their feeders.
To avoid the Carrier Tape wastage and Re-Taping, we would like to be able
to
splice Carrier and Cover Tape as needed. Some companies make splicing tools
intended for use by the chip shooter operators, to reduce the machine idle
time due to Reel changes.
I have the EIA-481 standards, but they do not specifically mention
splicing.
Do other component suppliers have this problem, how are you handling it.
How do the people on the assembly side see this, would it be acceptable to
get a Reel with splices?
Does someone out there make a generally acceptable splicing tool, that can
give us a reliable splice on Tapes with widths up to 32 mm?
Thanks,
Haim Halpert
