I'd don't believe that the reels need to be ESD protective material. The carrier and cover tape have resistivity and materials specifications. Start with EIA-481. In past threads on SMTnet, we have discussed problems in picking components that wer

We currently use Kapton tape to cover a display. The only real purpose for this tape is to cosmetically protect it thoughout the process. The display gets hand soldered and washed, so the idea of the tape being high temperture isn't a factor. Becaus

Potential causes are: * Static charge [get a deionizing fan] * Adhesive on the inside of the cover tape [fix your supplier]

Agree with Davef. Smaller the chip, more the static charge. I used to see this even with normal chips. Get an ionizer blow. It should solve your problem. May be switch to antistatic tape if affordable.Regards. GV

The carrier tape and cover tape of static sensitive components are either conductive or dissipative. as for the P&P machine, as long as they are made of metal and grounded, static buildup is not an issue. All PCB conveyors I've seen have static condu

Big problem. Certain LED from certain manufacturer sticks to the tape and reel cover tape. Peel back the cover tape and every LED lifts out of the embossed pocket and sticks to the cover tape. I believe this is from static and not any sort of adhe

Never assume static is static. We recently encountered something similar to what you describe. It turned out to be microscopic threads of glue (PSA from ther cover tape) over the pocket.

Usually Static in the tape will cause the component to stick to the cover tape as opposed to staying in the pocket. It sounds like you have another problem. But anyway, here is what we do when we "think" we have an ESA problem. We place the compone

you can check several things here: 1.Is this original tape or it is tape and reel service? 2. Is the cover tape that sticky, to lift component a little bit(sometimes might get the hole component). 3. Hole too loose, allow it to move too much 4. Fee

We have seen the same thing on small parts (8mm tape) and what we did is sprayed some ESD mat cleaner on a lint free towel and wiped the cover and carrier tape down. Since the cleaner is static dissipative the issue went away and we were able to get
