Simple PCB vise

This one almost got relegated to a links post, but [Ken’s] simple PCB vise (PDF) is just so useful we had to give it a standalone feature. It works so well because he made every design feature count.

For instance, the groove the holds the PCB (almost impossible to see here but look at the diagrams in the PDF linked above) is cut with a dovetail bit, rather than just being a square rabbit. The clamping force is provided by that blue rubber band which simply hooks on a metal shelf peg on each side of the clamping plates. Those plates are machined out of polyethylene and slide nicely along the two nylon rods which keep them aligned. There’s really nothing to break or wear out here, except the rubber band with is easily replaceable. The rubber feet keep it from sliding across the bench as you work.

This is great for soldering, and would go right along with those diy smd parts clamps you made. It’s also a great way to hold onto your prototype boards when you’re working out the firmware.

Surface mount solder assitant

Make sure those tiny parts know their place by using this surface mount solder assistant (translated). It’s like a clamp for small packages; gravity and a needle to hold them in place while you do some hand soldering. [Red Devil] started the built by soldering together some brass rails into a hinged frame with a clamp to accept the needle tip. Next, a pair of tubes were added to accept LEDs which light the work area (we think that’s a fantastic touch). Finally, the assembly was mounted to the corner of a square base that makes up the work surface.

This is basically a complex version of a simple gravity clamp. But if you’re doing some assembly line soldering this would be indispensable. For this kind of work, custom jigs are often built. That would still be the case, but this armature removes the need of building something into each jig to hold the SMD components in place.

DIY clamp helps with surface mount soldering

Hackaday writer [Gerrit Coetzee] built a simple clamp to aid in surface mount component soldering. This cheap, easily made device uses gravity to hold tiny components in place. The tip of the bolt is pointed, but gently like a ballpoint pen so as not to harm the components with a sharp tip. Roughly position your component, rest the tip of the clamp on its center, then nudge for final positioning. [Gerrit] also points out that this acts as a heat sink, helping to prevent damage to the component if you’re too lethargic with the soldering iron.

It seems like this device has been around in one form or another for quite a long time. But the best ideas do keep on popping up. Another nice tip to go along with this one is the use of a dowel when ironing during toner transfer for your PCBs.
