Application Requirements
Reliable fixture performance begins with the manufacturing process rather than a generic material claim. LH Stone reviews the thermal profile, PCB design, protected components, solder exposure, mechanical load, ESD needs and expected production volume before recommending a material or machining route.
Common Application Areas
- SMT production, PCB support plates and reflow carriers
- Wave solder pallets, selective solder fixtures and component protection tooling
- Semiconductor testing, precision positioning and electronics inspection fixtures
- Automotive electronics and new-energy vehicle electronic assemblies
- 5G communication equipment, industrial automation and optoelectronics
- Machine equipment, welding fixtures and high-temperature insulation components

Typical Production Challenges
- PCB bending or warpage during reflow or wave soldering.
- Fixture distortion after repeated thermal cycles.
- Electrostatic risk around sensitive ICs and electronic components.
- Wear, chemical exposure or cleaning damage during repeated production use.
- Inconsistent dimensions across replacement fixtures or repeat orders.
Recommended Workflow
