In defense systems, a single solder joint failure can disable an entire platform. That’s why IPC J-STD-001E is the global benchmark for soldering processes in mission-critical electronics.
Electromet integrates this standard into every enclosure that includes internal electrical assemblies or supports embedded OEM systems. This blog explains the role of IPC J-STD-001E, its Class 3 requirements, and how Electromet ensures solder quality throughout production.
Overview of IPC J-STD-001E
Published by the IPC Association, this standard outlines workmanship and quality benchmarks for soldered electrical and electronic assemblies.
Applications
- Surface mount and through-hole soldering
- Cable assemblies and wire harnesses
- Printed wiring assembly (PWA) terminations
For military applications, Class 3 is the highest quality grade—intended for products where continued performance is critical.
Class 3 Requirements
Class 3 enclosures and subassemblies must:
- Withstand vibration, temperature, and corrosion
- Exhibit perfect solder joints—no voids, bridging, or insufficient wetting
- Be traceable and inspectable per IPC-A-610 Class 3 criteria
Electromet ensures compliance through:
- Process control (solder paste storage, stencil cleaning, reflow profile verification)
- ESD-safe assembly environments
- Trained IPC-certified solder technicians
Material and Process Traceability
Our builds incorporate:
- SN63/Pb37 and SAC305 solder types depending on project spec
- RoHS and leaded processes as required
- Cleaning verification (ionic contamination testing)
All assemblies are supported with inspection reports, operator certs, and serial-level traceability.
Integration into Rugged Enclosures
Electromet often integrates soldered subassemblies into rackmount units and field enclosures. IPC J-STD-001E ensures these subsystems perform reliably inside environments qualified to:
- MIL-STD-810F (temperature, humidity, dust)
- MIL-STD-167-1A (vibration)
- MIL-DTL-901E (shock)
When solder integrity is a matter of mission success, IPC J-STD-001E is the standard Electromet trusts.
