Le Small Circuit Board Welding Fixture is a precision-engineered workholding solution designed to meet the rigorous demands of micro-electronics assembly. When working with small-scale PCBs, heat dissipation, component alignment, and board stability are the three biggest challenges; this fixture addresses all of them. By providing a rigid, adjustable frame, it eliminates “board flex” and prevents shifting during the soldering or welding process. This is particularly critical for surface mount technology (SMT) and fine-pitch components where even a fraction of a millimeter of movement can result in a short circuit or a failed joint.

By downloading this professional dessin, you gain access to a design that prioritizes both functionality and safety. The CAD data includes specifications for ESD-safe (electrostatic discharge) contact points to protect sensitive integrated circuits from static damage. The layout features adjustable “X” and “Y” axis sliders, allowing the fixture to accommodate various board shapes and sizes, from tiny wearable tech modules to standard industrial controllers. Furthermore, the design incorporates strategic thermal relief zones beneath the board to prevent the fixture from acting as a heat sink, ensuring that your welding iron or hot air station reaches the necessary temperature efficiently. Integrate this fixture into your production line to achieve cleaner solder joints and a significantly lower defect rate.

Caractéristiques principales :

  • Universal Size Adjustment: Features a sliding rail system with locking thumb screws to securely grip boards of varying widths.
  • ESD-Safe Material Specifications: The drawing includes callouts for conductive coatings or materials to prevent static buildup.
  • Low-Profile Design: Engineered to provide maximum clearance for soldering irons, hot air nozzles, and microscope lenses.
  • High-Temperature Resistance: Designed using materials that can withstand accidental contact with high-heat tools without deforming.
  • Non-Slip Weighted Base: Provides a stable center of gravity to prevent the fixture from sliding across the workbench during delicate operations.
