Roy,
Didn't know if I passed this info along. Sounds better than $ 40k automation!

Hey Ya'll!
Have any of you ever worked with one of V-Tek's "Economax" series of tape and
reel machines? One of the biggest things I'm curious about is the type of
cover tape that these machines use. It's something they call P.S.A. (Pressure
Sensitive Adhesive) cover tape. I've probably have used it in on my pick and
place machines in the past on some taped components, but wasn't aware of it.
The carrier tape you use on these machines can be of any type you want.
The cover tape is a little more expensive than heat sealed tape, but there's
a few good points about it that I know of: 1. I know with heat sealed tape,
if your reel sits on a hot shelf in the stockroom for a length of time, the
peel force will increase.
And 2.; I was told by V-tek that say if you discover that you accidently have
the polarity backwards on a few components in the middle of the reel, you can
peel up that section where the components are, put them back into the pockets
the right way, and then use your thumbnail to re-seal the tape back down.
The model that I'm looking at is one they call the "3 in 1 Economax". It's
basically a manual type of taping machine. You set the tape speed at whatever
speed you can keep up with, and feed the components into the pockets
manually. They say you can do anywhere from 500-4000 components and hour
depending on the type of component and how good your operator is at doing
this.
The 3 in 1 also is capable of being used as a reel counter, and has a peel
force tester incorporated into it. The other model that I'm looking at is
what they call their "ComPak Taper". Basically the same machine as the 3 in
1, but without the peel force tester and no counter. The ballpark prices
quoted to me were $7,000 for the "ComPak", and the "3 in 1" was $13,000. Not
too shabby, if they work good.
I've worked with both a Systemation ST-50 and ST-60 which are both heat-seal
types of tape and reelers...and I know that you're gonna pay a heck of lot
more for a Systemation than the V-Tek machines. But the Systemation machines
are also quite set-up intensive. From experience, I know a bad set-up can
cause you some major headaches...
We're not looking at this machine to get into the tape and reel business, but
just to have something inexpensive to do the one or two values in a job that
came to us in a stick...we're gonna push our customers real hard to give us
EVERYTHING on tape and reel in the first place.
I just wanna know if any of you have ever used V-Tek tape and reelers, what
you think about them, and also find out a little more about this P.S.A. cover
tape.
Thanks guys!
