Most through hole DIP ICs come with their pins splayed out. They have to be bent manually (usually against a table or by hand with pliers). If not bent so that they are straight, the ICs can be very hard to insert, or worse, you can bend one of the pins and break it.
I have broken more pins than I can count. This is why we designed our very own tool to prevent this exact problem.
Introducing the DIP CHIP STRAIGHTENER.
With support for both small and large DIP ICs. Simply place your IC in the middle and press firmly from both sides with your hand to straighten your pins. The unit is spring loaded so it will open back up once you are.
Perfectly straight pins that will slide into a socket or PCB with ease have never been easier.
