AEROSPACE

AS9100 Rev D goes beyond ISO 9001 by adding aerospace-specific requirements for risk management, configuration control, and product safety. It mandates documented process accountability at every production stage, from procurement through final acceptance. Calpak USA maintains AS9100 Rev D certification at our Hawthorne, California facility, meaning every aerospace assembly we produce is governed by formalized procedures for first-article inspection per AS9102, nonconformance disposition, and customer-flowdown requirements. For engineers and procurement managers evaluating contract manufacturers, this certification confirms that Calpak USA operates within a quality management system purpose-built for the zero-defect expectations of flight hardware, satellite subsystems, and avionics programs where field failure is not an acceptable outcome.

IPC Class 3 represents the highest tier of IPC-A-610 acceptability criteria, requiring tighter tolerances on solder joint formation, conductor spacing, and plated through-hole fill than Class 1 or Class 2 workmanship. At Calpak USA, every aerospace PCB assembly is built and inspected to these Class 3 requirements, which include minimum 75 percent vertical solder fill on through-hole joints, zero allowance for certain defect categories, and stricter annular ring specifications. Our IPC-certified operators and inspectors in Hawthorne, California are trained annually on Class 3 criteria. This level of workmanship is essential for assemblies exposed to high-vibration, thermal-cycling, and vacuum conditions found in launch vehicles, orbital platforms, and flight-critical avionics where long-term solder joint integrity directly affects mission success.

Calpak USA enforces full forward and backward traceability on every aerospace assembly, linking each finished unit to specific component lot codes, date codes, supplier certificates of conformance, and operator records. This traceability is maintained through our MES and ERP systems, capturing data at incoming inspection, SMT placement, reflow profiling, hand soldering, and test. Per AS9100 Rev D and customer-specific flowdown requirements, Calpak USA retains complete documentation packages including material certifications, X-ray images, and functional test results. When a procurement manager requires a deviation report or failure analysis months after delivery, our Hawthorne facility can trace any component or process step back to its origin within minutes, satisfying the documentation expectations set by prime aerospace contractors and government oversight agencies.

Calpak USA performs environmental stress screening tailored to each program's requirements, commonly including thermal cycling across military and aerospace temperature ranges such as minus 55 to plus 125 degrees Celsius, random vibration testing per MIL-STD-810 profiles, and powered burn-in to identify infant mortality failures. These screens precipitate latent defects in solder joints, component bonds, and PCB vias before assemblies reach the field. Our Hawthorne, California facility coordinates with accredited third-party test labs for HALT and HASS protocols when customer specifications demand them. Calpak USA engineers review screening data and provide detailed reports with pass-fail disposition, ensuring that only assemblies meeting the full acceptance criteria ship to the customer. This disciplined approach supports the reliability expectations of flight hardware and mission-critical avionics subsystems.

Calpak USA structures its aerospace manufacturing operations to handle the full program lifecycle, from initial engineering prototypes through low-rate production and into sustained full-rate manufacturing. During prototyping, our engineering team in Hawthorne, California provides DFM and DFT feedback, helping designers optimize pad geometries, component selections, and test access points before committing to production tooling. As programs transition to production, Calpak USA locks down validated solder profiles, establishes statistical process controls, and builds custom test fixtures for ICT and functional verification. This approach eliminates the costly re-qualification often encountered when companies use separate prototype and production vendors. With AS9100 Rev D governing every phase, Calpak USA delivers configuration-controlled assemblies that satisfy first-article inspection requirements and maintain consistent quality across lot sizes ranging from ten units to several thousand.
