Twisting the stranded wire with your fingers in preparation for tinning and / or welding is almost a reflection of the person making the electronic components. But what if the wire is too close and your fingers can’t be wound, or you have sumo wrestler’s fingers? Diydsp provides you with a solution (see the video below), which can be easily made from the rolling barbecue strings in your kitchen drawer. [diydsp] the reason why we want to twist such closely spaced wires is to weld the 0.1-inch O.C. stranded ribbon cable directly to the PCB pin head pattern.
The method is very simple. Drill a long hole in the flat end cut at the factory, and then use a countersunk drill to form a conical taper to guide the wire in. [diydsp] found that a 1 / 16 inch (1.6 mm) drill bit was too large to grasp the type of wire he was using, and finally decided to use a 0.6 mm drill bit. If you’re using larger wires, you should try to get the right size, or just make wires of different diameters, because they’re easy to make – just mark them clearly so you don’t accidentally use them to roast kebabs during barbecue.
The resulting tools are no different from the business end of hand-held winding tools, but the working principle is different, accounting for only a small part of the cost. If you use twisted wires for any number of interconnect wiring, you should check this video and quickly make two of them and throw them into the toolbox.
