Modular Fixture Plates Perfect For Small Production Runs

If you’ve ever done any small production runs of anything that needs a bit of assembly, you know that jigs and fixtures are a huge time saver. However, these usually need to be mounted, which means you end up drilling holes in your workbench or making one-off mounting plates. [Jim Smith] is no stranger to this problem, and created the Pact Plate, an affordable modular fixture plate and is running a Kickstarter campaign to get it produced.

Each plate 150 mm × 150 mm in size with a 25 × 25 mm grid of holes with M4 threaded inserts. This allows quickly and easily mounted to and removed from the plate without the need to drill additional holes. Plates can be bolted together to form larger plates. The demo video shows him using a variety of 3D printed jigs, toggle clamps, PCB and part holders (available for download) and even a robot to quickly set up small assembly stations. This could also save a lot of time during the prototyping and development phases to hold parts in place.

[Jim]’s prototypes are all 3D printed, but want’s to get tooling made to produce the plates using injection moulding. He doesn’t say what material he intends to use, but it’s likely some type of fibre reinforced plastic. He claims the rigidity is close to that of die-cast aluminium. One addition we would like to see is some plugs for the unused hole to prevent small components from falling into them.

The Obscure Electronics Tools You Didn’t Know You Needed

The right tool for the job can turn a total headache into a 30-second operation. This is all the more important when you’re trying to streamline an assembly process, and the reason why you’ll find so many strange and wonderful purpose-built tools on any production line. With a nod to that old adage, [EvilMadScientist] have collected the tools you didn’t know you needed – until now.

If you’re wiring big through-hole boards all day, you’ve probably bemoaned the uneven bends on all your resistors. How did the big companies get it right way back when? They used a tool to set the distance of the resistor legs just right. What about DIP ICs? It’s a total pain trying to take them fresh out of the tube and get them to seat in a socket, but there’s a tool to do that too. It’s actually a two-part series, and while we’re sure you’ve all seen a solder sucker before, the fresh take on helping hands is pretty ingenious.

Overall, it’s a combination of little things that, with a bit of cash or a day’s work, you can have in your own lab and once you’ve got them, you won’t ever want to go back. Be sure to tell us about your favourite obscure tools in the comments.

Now that you’ve got your tools to hand, why not wrap them all up in a handy workstation?
