Industrial electronics operate in environments that consumer and commercial gear never faces. A PLC on a factory floor may run continuously for 5-10 years without a power cycle — through temperature swings from -40°C to +85°C, constant vibration from nearby machinery, airborne contaminants, and voltage transients from heavy equipment switching.
This demands a fundamentally different approach to PCB design and manufacturing. Industrial boards require heavy copper (up to 12 oz) for high-current power distribution, high-Tg laminates (170-180°C) for thermal reliability, conformal coating against moisture and dust, and reinforced isolation barriers between high-voltage and low-voltage domains. Every design decision — from creepage distances to CTI ratings — must account for the reality that these boards cannot fail.
Component lifecycle management is equally critical. Unlike consumer products with 18-month refresh cycles, industrial equipment often stays in production for 10-15 years. Superb Automation actively manages EOL notifications, last-time-buy windows, and alternative sourcing to ensure your BOM remains viable throughout the product's service life.
