HONGMAO's industrial snap domes combine patented venting technology with laser-welded contacts for vibration-resistant performance. Key features:
MIL-STD-202G compliant shock/vibration resistance
8kV ESD protection (IEC 61000-4-2 Level 4)
Optional conductive adhesive backings for SMT compatibility
Custom force gradients within single arrays
Our 12,000㎡ production facility houses 18 automated stamping lines with ±0.02mm dimensional accuracy. Snap domes undergo rigorous salt spray (500+ hours) and thermal cycling tests (-55°C/+150°C). Technical support includes ANSYS simulation for optimal PCB layout integration.
Our 50-point QC process includes:
Contact resistance (<20mΩ)
Adhesion peel strength (≥3N/mm)
8-hour salt spray testing
X-ray weld inspection
HONGMAO's patented progressive die technology achieves 98% material utilization. Automated AOI systems maintain <0.1% defect rates while reducing production costs by 30%.
Military-grade snap domes feature:
• IP69K waterproof sealing
• -55°C to 150°C operational range
• 500VAC dielectric withstand
HONGMAO engineers bespoke snap dome arrays with:
Chemical-resistant PET/PC substrates
EMI shielding coatings
Multi-stage force gradients
All solutions undergo 500-cycle pre-testing and thermal shock validation.
