Emergency DIP Pin Repair For Anyone

Who has not at some point in their lives experienced the horror of a pin on a DIP package breaking off? It’s generally game over, but what if you don’t have another chip handy to substitute? It’s time to carefully grind away some of the epoxy and solder on a new pin, as [Zafer Yildiz] has done in the video below the break.

The technique relies on the pins continuing horizontally inside the package , such that they provide a flat surface. He’s grinding with the disk on a rotary tool, we have to say we’d use one of the more delicate grinding heads for something more akin to a miniature die grinder.

Once the flat metal surface is exposed, the chip is placed in a socket, and a new pin is cut from the leg of a TO-220 power device. This is carefully bent over, inserted in the socket, and soldered into place. The whole socket and chip arrangement is then used in place of the chip, making for something a little bulky but one infinitely preferable to having to junk the device.

There are many useful skills to be learned when it comes to reworking, and we’ve covered a few in our time. Most recently we saw a guide to lifting SMD pins.

Lift Those Pins With Ease

Reworking is one of the regular tasks of anyone who is involved in an electronic design process, because try as we might, it’s rare to get a design perfectly right the first time. Some reworking tasks are more difficult than others though, and we have to admit that lifting an IC pin doesn’t always result in success. But with this video from [Mr. SolderFix] there’s hope for conquering the technique, as he takes us through the best pin-raising technique on a variety of packages.

The trick it seems is to lift the pin first without attempting to disengage it from the molten solder, then returning to it with some copper braid to remove the solder and leave it raised. Once the secret is revealed it’s so easy, something a Hackaday scribe should be able to do. He does sound a note of caution though, as some packages are prone to disintegrating when stressed. A broken SOT-23 is not something anyone likes to see through their magnifier.

His channel is full of such no-nonsense soldering advice, and should be a fascinating browse for many readers. Meanwhile we’ve covered quite a bit of rework technique ourselves, such as last year when we looked at BGA work.
