Application Overview
Purpose
- A fixture for soldering PC board.
Points for use
- Operating procedure
- The PC board is held down by the fixtures cover.
- User can perform soldering work on the first side of the PC board.
- After soldering the first side, lift up the cover, then remove and refit the PC board to its opposite side.
- Fold down the fixture cover again and begin soldering work on the 2nd side of the PC board.
Target workpiece
- PC board
- Dims.: W70 x D45 x t1 (Also compatible with PCB W40 x D80 x t1)
Design Specifications
Operating Conditions or Design Requirements
- External dims.: W120 x D120 x H30
- Magnet; 7.84N
Required accuracy · Load
- Cover retaining force: 5.9N
Selection Criteria for Main Components
- Magnet
- Magnetic hold down force should be sufficient to keep the PCB in place during soldering, and yet minimal enough for easy lifting of the cover when soldering is complete.
- As an example, select magnets with attraction force of approximately 5.9N.
Design Evaluation
Verification of main components
- Consider adding handle or hex posts for lifting of cover and overall handling of the fixture.
- When reversing, load applicable on the magnets: Cover + Hex posts + PCB = 45g + 10g + 5g ＝ 60g ＝ 0.59N
- Distance between the magnets and magnetic material: 2mm (Magnetic material: 4137 Alloy Steel, screw head)
- Assumed decay: 0.1
- Attraction to prevent cover opening: 0.59 / 0.1 = 5.9N
- Magnetic attraction can vary based on distance, temperature, material and size of magnetic body. Selection is to be made upon actual measurements.
Other Design Consideration
- Since soldering is applied on reversed sides, hex posts are provided as feet on the cover side. The posts are also used as handles for cover open/close.
- Locating pins are used to locate the cover.
- Add notches as needed to avoid wire harness, etc.
- The hex socket screw heads are used as attracted member since the main body and the cover are made of non-magnetically permeable material.
