Overview
Pearson Manufacturing connects OEMs and defense contractors with precision electronic housings, chassis, and enclosures designed for harsh environments. We fulfill orders through our in-house shop or a network of certified Canadian partners — managing sourcing, ruggedization details, and inspection so your assemblies are deployment-ready.

Quick Specs
Workstream | Best For | Speed | Notes |
---|---|---|---|
Prototype / EVT | Fit/thermal/EMI exploration | Fast | Quick-turn enclosures, heatsinks, and fixtures with DFM feedback |
DVT / Pre-Qual | Design verification & test jigs | Medium | Tightened tolerances, gasket features, selective finishing |
Qualification / QTP | Formal environmental/EMI qual | Medium | Traceable docs, special processes, witness samples |
Production / Sustainment | Rate builds & spares | Medium | Kanban/VMI, serialization, inspection packs, packaging specs |
Capabilities We Provide Access To
- Precision CNC machining of rugged enclosures, heat sinks, and backplanes
- Shielded sheet-metal fabrication (laser/brake) with captive hardware
- RF/EMI features: gasket grooves, labyrinth joints, shield cans, grounding bosses
- PCB test jigs/fixtures, connector panel machining, press-fit prep
- Conformal coating/potting coordination; thermal interface prep (TIM pockets, flatness)
- Cable harness integration, light electromechanical assembly, and kitting
- Environmental & functional testing coordination with accredited labs
DFM & Compliance Guidance
- Define a clear A-B-C datum scheme; apply GD&T only to CTQs (EMI seals, mating faces, connector positions).
- Add gasket groove standards (width/depth/compression) and fastener spacing to meet shielding targets.
- Prefer chem film on mating/grounding faces for conductivity; use selective anodize or mask critical areas.
- Provide flatness targets for heat-spreading bases; specify TIM thickness/area and screw torque specs.
- Call out thread classes/gauging (e.g., 2B/3B; go/no-go); consider helicoils in soft alloys for repeat service.
- Include labeling/marking, serialization, and packaging requirements (ESD, humidity indicators, foam density).
We’ll review your model/drawing, sealing and EMI requirements, finish/masking notes, and packaging to confirm the right routing (in-house or partner) and achievable tolerances before kickoff.
Why Partner with Pearson?
- Hybrid fulfillment: in-house machining plus certified Canadian partners for scale and specialties
- Ruggedization know-how: thermal, EMI/EMC, vibration, and sealing features baked into DFM
- Documentation ready: FAI/FAIRs, traceability, and test coordination under one QA umbrella
- Prototype-to-production continuity: fixtures, programs, and process controls carried forward
- Single point of contact from RFQ through inspection and logistics
Equipment Used In-House or By Our Partners
- 5-axis & multi-axis CNC mills; small-tool capability for fine fins/slots
- High-precision press brakes; laser/waterjet cutting (by routing)
- Conformal coating & potting systems (by routing) with masking fixtures
- Cable harness crimping/labeling tools; light assembly cells
- Environmental chambers (thermal/vibe) and EMI test coordination
- CMMs, optical inspection, and laser scanning for geometry & flatness
Typical Applications
- Avionics LRUs: ruggedized enclosures, bezels, and connector panels
- Thermal management: heat-sink plates, spreaders, and cold plates
- Shielded backplanes, RF cans, and conductive gasket interfaces
- Sensor/antenna modules and sealed electronics chassis
- Ground vehicle power distribution & bus bar assemblies
- Test fixtures, docking plates, and cable/harness panels
Defense Electronics FAQs
Are assemblies built in-house or through partners?
Both. We operate a hybrid model. Some machining and light assembly occur at our Ontario facility; other steps (e.g., coating, larger runs, specialized testing) are fulfilled through certified Canadian partners under Pearson QA.
Do you support MIL-STD or DO-160 testing?
Yes. We coordinate environmental and EMI/EMC testing through accredited labs and provide the documentation package (test reports, FAIRs, CoCs, photos) with your shipment.
Can you support ITAR/CGP-restricted programs?
We comply with applicable export controls and can route ITAR/CGP-restricted work via qualified partners. Share your compliance needs with the RFQ for correct routing.
What tolerances and flatness are typical for enclosures?
As a baseline, ±0.001–0.002″ on CTQs for metals; flatness targets for heat-spreader faces commonly 0.001–0.003″ depending on size and process. We’ll confirm after review.
What should I include with my RFQ?
CAD + PDF with GD&T, BOM/AVL, finish/masking notes, gasket spec, serialization/packaging needs, expected test/qualification scope, target quantities, and schedule. Start your defense/avionics quote — include finish/masking, gasket spec, serialization, test scope, and schedule.
