Principal Manufacturing Engineer (PCBA)

As a Principal Manufacturing Engineer (PCBA) at Impulse, you will be the recognized expert on printed circuit board assemblies (PCBAs) and will provide deep technical expertise on PCBA technology for spaceflight. You will bridge the gap between Design and Manufacturing, ensuring our designs are fully optimized for manufacturability, testability and reliability. 

Responsibilities

• Provide technical leadership across the company as the subject matter expert on PCBAs, including manufacturing process, materials, design for manufacturability, environmental testing and qualification, etc. 
• Develop, qualify and optimize manufacturing processes for PCBAs, including solder rework, SMT, conformal coating, staking, underfill and inspection
• Develop, characterize, and optimize PCBA assembly processes, including: 
  • Hand soldering/solder rework, wave soldering, reflow soldering, selective soldering
• Apply an understanding of soldering physics, including: 
  • Heat transfer and thermal profiles 
  • Wetting, spreading, surface tension, and intermetallic formation 
• Serve as a subject-matter resource for PCBA rework and repair, including: 
  • Component removal and replacement 
  • Pad repair 
  • Solder-joint rework 
  • Localized thermal processes 
  • Damage prevention 
  • Cleaning and inspection 
  • Rework documentation and acceptance criteria 
• Provide technical expertise on environmental testing of PCBAs, including vibration, thermal cycling and thermal vacuum
• Collaborate with design engineers to ensure manufacturability, testability, reliability, drawing review and DFM/DFA of PCBAs
• Serve as technical expert on troubleshooting production issues, identifying root causes, and driving implementation of corrective actions for non-conformances
• Own company specifications on PCBAs
• Stay up-to-date with industry trends, emerging technologies, and best practices in PCBA manufacturing to drive innovation and implementation of lead-edge technology

Minimum Qualifications

• Bachelors' degree in Materials Engineering, Physics, Chemistry, Electrical Engineering, or related field  
• 10+ years of demonstrated manufacturing experience with PCBAs, including SMT, conformal coating, staking, underfill
• 10+ years of demonstrated inspection experience with PCBAs, X-ray/CT, flying probe and AOI. 
• Deep understanding of materials used in PCBs and PCBA manufacturing
• Strong practical knowledge of hand soldering, wave soldering, reflow, selective soldering, component attachment, and terminal soldering
• Experience with soldering physics, fluxes, solder alloys, surface finishes, thermal profiles, solderability, and common soldering defects

Preferred Skills and Experience

• 15+ years of demonstrated manufacturing and inspection experience related PCBAs, 
•  M.S. or Ph.D. in Materials Engineering, Physics, Chemistry, Electrical Engineering, or related field 
• Experience with PCB and PCBA manufacturing for space applications.  
• In-depth understanding of PCBA functional testing, software testing and environmental testing.  
• Experience automated optical inspection (AOI), and X-ray/CT inspection of PCBAs
