I recently ordered a set of “PCBite”. These are special PCB holder as shown in the images in this post. To solder components into PCB I sometimes used one of this many “helping hands” products with two clamps, but they are no real use in most cases.
PCBite seems to solve some of the problems very well. You get a metal plate with a mirror finish and four of this cylinders which have a very strong magnet in the base. The middle part of the cylinder with the grip on is can be moved down and the PCB fastened that way. It is very solid and two would be enough to hold the PCB easily.
The mirror finish makes the bottom side of the PCB easily visible so you can solder on the top side and keep the component in view.
The shown PCB is from my Outmoded Sequencer project.
You can get you own set for $79 here, this includes free shipping. The quality of this PCB holder is outstanding. If you look at the close up photo, you see the perfection how this tool was made. I can really recommend this PCB holder.
Currently I am working on the final assembly of the Outmoded Sequencer, it looks very promising. There will soon be an update with all details about the final device.
Wow I just need one!!
