Navigating the Labyrinth of Space-Grade Hardware Manufacturing
A Comprehensive Exploration of the Key Elements in Building a Lean, Quality-Driven Manufacturing Environment
Embarking on the journey of space-grade hardware manufacturing involves multiple factors to consider, from supplier management to quality control. Here, we dig deep into these components, emphasizing lean operations, adherence to quality, and fostering a robust startup culture.
Purchasing and Supplier Management
Electronic Components
Suppliers like Digi-Key and Mouser Electronics are reliable sources for a wide array of electronic components.
PCB Assembly
For assembling Printed Circuit Boards (PCBs), options include both turn-key services and consignment:
Turn-Key: Service providers handle everything from sourcing components to assembling the PCBs. Pros include simplicity and time savings. Cons might include a lack of control over component procurement and potentially higher costs. Examples of such services are PCBCart and Advanced Circuits.
Consignment: You provide the necessary components and the service provider assembles them. Pros include better control over component quality and potentially lower costs. Cons might include the extra time required to manage component procurement.
Mechanical and Machined Components
For mechanical components and machined parts, services like 3DHubs and Fictiv provide accurate and efficient machining services.
Consumables: Adhesives and Thermal Interface Materials (TIM)
Adhesives and TIMs are crucial in space manufacturing for their roles in assembly and thermal management. Industry-standard adhesives include 3M's Thermally Conductive Adhesives and Henkel's LOCTITE®, renowned for their superior bonding strength and durability.
Facility Setup and Tools
Optimizing your facility layout for efficiency and safety is crucial. Essential tools for various tasks can be purchased from suppliers like MSC Industrial Supply or Grainger.
Integration and Assembly
Detailed work instructions are vital for ensuring an efficient assembly process. Implementing a robust configuration management process to control and document changes is key.
Testing
In-process and final testing strategies need to be developed, incorporating techniques like 'Bed-of-Nails' for PCB testing, and Thermal Vacuum (TVAC) and Vibration (VIBE) testing for the final Acceptance Test Procedures (ATP).
Quality Assurance and Defect Handling
Implementing a Material Review Board (MRB) process that adheres to NASA's quality standards is vital for handling defects and ensuring the highest quality standards.
Shipping
When preparing for shipping, consider programs like UPS's CubeSat Launch initiative or FedEx's Space Solutions. Proper packaging is essential to avoid any damage during transit.
Software Recommendations
Software solutions like SOLIDWORKS for design control, Arena Solutions for manufacturing execution, and Fishbowl Inventory for inventory control can streamline your manufacturing process.
Following these strategies will put your space-grade hardware manufacturing startup on a solid path, fostering a culture of high quality and efficient operations.
