199X98X38 MM

Q:What defines the physical structure of 199×98×38mm Package?

A:Key features include:
- Large PCB footprint: Optimized for high-power/high-current applications (199×98 mm base area).
- Integrated thermal management: Full-coverage metal baseplate (98×38 mm central region) for heat dissipation.
- Robust mechanical design: 38mm height with reinforced sidewalls for structural rigidity.
- Modular pin layout: Configurable multi-pin arrays (e.g., 50-pin dual-row edge connectors).

Q:Why choose 199×98×38mm Package over alternatives?

A:Critical advantages:
- High power handling: 30% greater current capacity vs. standard 150×80mm packages.
- Thermal Performance: Direct-attach baseplate reduces thermal resistance by 40% (vs. screw-mounted heatsinks).
- Electrical Benefits: Low-inductance busbar integration for <1nH parasitic inductance.
- Reliability: Hermetic sealing (IP67) for harsh environments.

Q:What are common technical specs?

A:Standard configurations (consult datasheets):
- Body Size: 199×98 mm (L×W).
- Height: 38 mm (including baseplate).
- Pin Pitch: 5.0 mm (customizable to 2.5 mm).
- Material: Aluminum alloy base with FR4/PI hybrid substrate.
- Temp Range: -40°C to +150°C (operational).

Q:Where is 199×98×38mm Package typically applied?

A:Dominant use cases:
- Industrial power systems: High-current motor drives (e.g., 500A inverters).
- Renewable energy: Solar/wind converter modules (e.g., 1MW PV inverters).
- Transportation: EV battery management systems (e.g., 800V charging modules).

Q:What are critical assembly guidelines?

A:Key recommendations:
- PCB Design: 2oz copper layers + thermal vias (≥20 vias/cm² under baseplate).
- Solder Paste: High-temperature SAC305 (Type 5 for fine-pitch components).
- Reflow Profile: Ramp rate ≤2°C/s, peak 250°C (baseplate pre-heat to 180°C).
- Inspection: Post-assembly thermal cycling (-40°C/+125°C, 500 cycles) + AXI.
