Tight-Tolerance Crystal Resonator for Two-Way Radios
Crystal reliability tests: free fall six times from75cm onto a2cm-thick rubber board, with post-drop frequency deviation≤4ppm. Vibration:10–55Hz,0.75mm amplitude,30minutes per XYZ axis; frequency change≤±20ppm. Lead strength: hold body and apply0.9kg axial pull for30±5s without lead pullout/breakage. Sealing: immerse in alcohol at stated pressure5kg/cm for5minutes, then lead-to-base insulation>500MΩ at DC100V. Temperature cycling retains the stated sequence “2–3min, -20℃…+70℃,30min,30min”; after three cycles, no damage and vibration-equivalent performance. Solderability: immerse leads at2–3.0mm from the stated end/base position in230±5℃ solder for2±0.5s, coverage>95%, with vibration-equivalent performance. Solder-heat resistance:2–2.5mm position,350±10℃ for3.5±0.5s, no abnormal appearance and vibration-equivalent performance. Low temperature:-25±3℃ for2hours, then2hours recovery at room temperature. The high-temperature-resistance test is stated as-70±2℃ for2hours, then2hours recovery. Both use vibration-equivalent performance. Damp heat:40±3℃,RH93%±2%,48hours, then2hours recovery, no abnormal appearance and vibration-equivalent performance. Aging:80±2℃ for72hours,2hours room-temperature recovery, frequency change≤±5ppm and resistance change≤±15Ω.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.
Driven by the rapid upgrading of intelligent vehicles, optoelectronic sensing technologies represented by laser sensing and infrared thermal imaging have become core pillars for high-level autonomous driving and smart cockpit iteration. Leveraging automotive-grade optoelectronic R&D advantages, Pilot Technology Group launches the VITAL intelligent vehicle solution. By integrating high-power VCSEL laser chips and vehicle infrared night-vision thermal imagers, the system comprehensively enhances vehicle environmental perception and realizes safer, smarter and more comfortable driving experiences.
