IC PIN Straightening Tool for DIL (DIP) Integrated Circuit

Updated 08/30/2026 Part List Links

Hi

Appearing in this format in the 60's, many of the integrated circuits that we are still called to use are still in the good old DIL (or DIP, CERDIP, SPDIP,..) package.

We use them in this form because in the case for example optocouplers or transceivers, they are placed on support and their replacement is easy.

A small circuit easy to make on a prototype board will be even more if the components are in the traditional format.

Unfortunately, the storage of these components is delicate and often we have a hard job to do, straighten all the legs of the component we want to use.

So I designed this tool that allows in a split second to straighten all the pins of these precious components.

Here are the cheapest bearings...

and some washers adaped

Just add 4x 3M rubber foots on the bottom face

...and you will get a professional product

All I ask in return if you like this design is to post your achievement, I will be happy to see your print and to know how this tool is useful for you.

Happy printing !
