PCB Holder

thingiverse

If you're one of those people who like electronics, then you know how frustrating it can be when you need to hold a PCB for soldering a component. That was my case when I decided to make a stand PCB. First I was looking at what was available in the market (Weller by example), in order to have some reference on which to base my design. Finally, I decided on a type of support that allows to turn the PCB in order to be able to have easy access to both sides of it. The hardest part was to design the clamping mechanism. In the end I think I found a good solution, based on three springs that allow the PCB firmly secure but at the same time release with little effort, to rotate if necessary. BOM & Instructions BILL OF MATERIALS (BOM) ROD LOCKERS: 4x M3 Nuts 4x M3 Bolts of 25 mm LEFT HAND: 1x M3 Nut 1x M3 Nut with auto-lock 1x M3 Bolt of 25 mm 1x Spring of 0,8 mm Wire diameter x 12mm Length x 13 mm inside diameter aprox. RIGHT HAND: 5x M3 Nuts with auto-lock 4x M3 Bolts of 20 mm 1x M3 Bolt of 25 mm 1x M3 Washer 2x Springs of 0,35 mm Wire diameter x 12 mm Length x 8 mm inside diameter aprox. 1x Spring of 1,5 mm Wire diameter x 36 Length x 14 mm inside diameter aprox. The RODS I am using in this unit are recycled from an inkjet printer. You need two of 8 mm of diameter by 400 mm of length. Also I am making some type of video tutorial to do more easy the steps needed to assembling this thing ;) PCBHolder Part 1/3 (Left Hand) PCBHolder Part 2/3 (Right Hand) PCBHolder Part 3/3 (Finished) Project: PCB Holder Project Name PCB Holder. Overview & Background By doing this project you can learn to use software like: FreeCAD, InkScape, KiCAD, Cura, Slicer, Repetier. Objectives The main objective is learn to use 3D design software and how students can be able to make their own Tools, also to recycle non used material (be green student!) Audiences: This project can be carried out by any enthusiast. Subjects No special. Skills Learned (Standards) 3D Design, Vectorial drawing Tools design. Lesson/Activity FreeCAD software Inkscape software 3D Printer software (Cura, Repetier, Slicer, etc.) Duration It is a relative question but if the teacher only make use the main features of the software, they could be able to do this thing/project in lest than some hours. Preparation If they only want to do this project, they only must to know how to print this thing in a 3D printer! References No special references. Rubric & Assessment They should have learned how to use 3D design software, vectorial drawing software. Handouts & Assets
