| 01 EV platforms introduce additional complexity—fast-switching SiC inverters, high-current HV buses, dense BMS monitoring, and mixed-signal electronics that must survive a decade (or more) of thermal cycling. | |
| 02 Automotive electronics operate under conditions that normal consumer hardware will never experience —heat, cold, vibration, high voltage, electrical transients, long duty cycles, and strict safety expectations. |

The exact engineering checks we perform for each project include:
|
|
|
|---|---|---|
ISO 7637-2 transient & load-dump vulnerability | Reviewing input protection (TVS), filtering, grounding, and return paths | Prevents resets, latent damage, and field failures during vehicle transients |
HV isolation gaps and routing in compact layouts | Validating creepage/clearance, slots/keepouts, coating strategy, CTI/material limits | Reduces arcing risk and supports functional safety and HV compliance |
Partial discharge risk in HV nodes and edges | Flagging sharp copper edges, void-prone structures, spacing at HV transitions | Avoids insulation degradation that shows up after thermal cycling |
Thermal hotspots in high-current paths (inverters, DC-DC, busbars) | Assessing copper weight, current density, via stitching, heat spreading and sinking paths | Prevents overheating, delamination, and accelerated aging |
EMI coupling from power stages into sensing/communication | Calling out noisy return paths, switching loops, partitioning, and shielding opportunities | Improves CISPR 25 margin and reduces intermittent performance issues |
Vibration-driven fatigue at connectors and heavy components | Stress-checking anchor points, pad/trace reinforcement, teardrops, stiffeners, and stackup rigidity | Reduces cracked joints and intermittent opens under vibration profiles |
Corrosion susceptibility in harsh environments (salt fog, moisture) | Reviewing surface finish, edge plating needs, conformal coating coverage, and leakage paths | Prevents leakage, dendrites, and long-term reliability drift |
SI integrity on automotive high-speed links (CAN FD / Ethernet) | Reviewing impedance targets, pair routing, reference continuity, skew, and stubs | Avoids late-stage link instability and EMI surprises |
