I ordered a bulk quantity of components for experimentation and they were shipped in a cut tape format.

I've been removing components individually from the tape but it requires a large amount of labor, removal of tape residue from the leads, etc.

Is there a better method?

  • \$\begingroup\$ Ah, through hole components in tape. What a pain. How many components are we talking about? Can't be many if it's for experimentation. \$\endgroup\$ – Samuel Mar 17 '15 at 23:05
  • \$\begingroup\$ What kind of component have you got? A picture of the tape with components could help here. \$\endgroup\$ – Nick Alexeev Mar 17 '15 at 23:06
  • \$\begingroup\$ If it's a radial electrolytic capacitor like that, you can make leads slightly different length as you cut them. That way you will have an extra bit of polarity coding. \$\endgroup\$ – Nick Alexeev Mar 18 '15 at 4:53

The top tape should just peel back, and should allow you to dump the components on the table. I have never heard of tape residue on the leads.

If there is such residue, you could either bathe them in an electronic cleaning solution (3M Novec comes to mind) or just cut the residue parts off, if the leads are long enough.

EDIT: I just realized you are talking about through hole components. Most of the time, I have never needed to clean them, as we cut the leads after they are soldered into the board, and you can just let the residue part be. An easy way to prep the components is when you are about to solder, apply some flux from a flux pen, and that should clean the surface so that you can solder it. 3M Novec would also work too on this as well.

For reference to others, this is what I believe that you are referring to. enter image description here

  • \$\begingroup\$ That is exactly what I am dealing with. I expected I could just peel the tape or pull the components out but the tape was so secure that I had to score the leads with a knife in order to remove a few and that left the residue. \$\endgroup\$ – jamesallman Mar 17 '15 at 23:36

    \$\begingroup\$ Wow, talk about poor packaging. Soak the tape in a (non conducting) liquid then pull the components out? \$\endgroup\$ – Reid Mar 17 '15 at 23:44

For leaded components on tape, I'd just cut the component leads at the tape - you very rarely need the full lead length.

    \$\begingroup\$ That's so obvious I would have never thought of doing it the easy way! \$\endgroup\$ – jamesallman Mar 17 '15 at 23:38

    \$\begingroup\$ You can often use scissors rather than diagonal cutters, so you don't have to cut one lead at a time. \$\endgroup\$ – Jeanne Pindar Mar 18 '15 at 3:39
  • \$\begingroup\$ This works but loses the polarisation information in different lead lengths (seen in the top image), so only suitable for when you're immediately inserting it into a board. \$\endgroup\$ – pjc50 Mar 18 '15 at 10:57

    \$\begingroup\$ Those electrolytic caps have a polarization marking on the part. I don't know of any parts where polarization is shown only by the length of the leads. \$\endgroup\$ – Jeanne Pindar Mar 18 '15 at 13:04

I get a lot of transistors, and resistors that are on tape. Goof off softens the tape nicely and vinegar helps to get rid of the glue. Old stock components are harder and require overnight soaking, so I use 2 parts water to 1 part windex for that
