GPS Tracker PCBA: Comprehensive Guide to Manufacturing Process & Material Selection

 

Product Overview & Core Advantages

GPS Tracker PCBA (Printed Circuit Board Assembly) serves as the core component of modern tracking devices, integrating GPS modules, communication chips, microprocessors, and sensors. Our professional manufacturing delivers high-quality, reliable solutions for vehicle monitoring, asset tracking, and personal safety applications.


Key Features:

  • High-precision positioning: Multi-mode GPS/GLONASS/BeiDou chips with 2.5m CEP accuracy
  • Low-power design: Optimized power management with standby current as low as 5μA
  • Robust construction: FR-4 high-Tg materials (-40℃ to +85℃ operating range)
  • Compact size: 25×25mm achievable through multilayer stacking
  • Rich interfaces: UART, I2C, SPI, USB for seamless integration

Material Selection


1.Substrate: FR-4 high-Tg (≥170℃) for thermal stability, Rogers RO4350B for RF circuits (εr=3.48, tanδ=0.0037)

2.Copper foil: Reverse-treated foil (Rz 3-5μm) with 1oz standard thickness (2oz for high-current paths)

3.Surface finishes:

  • ENIG (0.05-0.15μm Au) for high reliability
  • Immersion Silver for cost-effective solutions
  • OSP for rapid production
  • Hard gold plating for connectors

Manufacturing Process
  • Multilayer lamination: 4-8 layer sequential build-up with ≤50μm layer alignment
  • Drilling: UV laser (0.1-0.15mm micro-vias) + mechanical drilling (0.2mm bits at 180Krpm)
  • Circuit patterning: LDI for 25μm line/space, alkaline etching (50±2℃)
  • Solder mask: LPI (15-25μm) with 6H hardness after curing

Critical Controls
Impedance: 50Ω RF traces controlled via TDR testing

Soldering: SAC305 alloy, peak temp 235-245℃ (40-60s above 217℃)

Reliability testing:
  • Thermal cycling (-40℃~+85℃, 100 cycles)
  • Humidity (85℃/85%RH, 96hrs)
  • Vibration (10-500Hz, 3-axis)

Quality Assurance

  • AOI (99.5% defect detection)
  • SPI (CPK>1.67 for solder paste)
  • Flying probe electrical testing
  • Functional GPS signal simulation

Support Services

 

  • Design review (SI/PI/EMC analysis)
  • Flexible production (prototype to 500K/month)
  • Application-specific solutions:
  • Automotive (AEC-Q100 compliant
  • Industrial (conformal coating options)
  • Wearables (rigid-flex designs)

FAQ Highlights

  • Lead time: 20 days standard (10-day expedited available)
  • Size minimization: 20×30mm achievable with HDI technology
  • Outdoor protection: UV-resistant solder mask + IP68 connectors
  • Power optimization: PSM mode + dynamic GPS refresh rates
