Defining Industrial PCBs
Industrial PCBs differentiate on:
Operating Environments – Made for extreme industrial settings with
wider temperature (-40°C to 105+°C), shock/vibration, humidity and
other environmental demands.
Lifespan – Designed for high reliability over long product field
life, often 10-15+ years of near continuous operations.
Criticality – High availability, functionality and safety
criticality if the PCB fails. Whole industrial systems may rely on
them.
Some examples of electronics using specially designed industrial
class PCBs include:
Ruggedness, extended lifespan and high reliability distinguish
industrial PCBs even though they may resemble commercial boards
upon visual inspection. Their unique constraints lead to various
design and manufacturing rules.
Substrates
| Material | Properties | Applications |
| FR-4 Glass Epoxy | Low cost, moderate performance | Mild environments |
| High Tg FR-4 | Increased heat resistance | Power electronics |
| Polyimide | Extreme temperature range | Downhole, space, aviation |
| IMS | Thermal conductivity | LEDs, power devices |
| Ceramic | High frequency, temperature | RF/microwave, harsh |
| Metal Core | Heat dissipation | Power, LED |
How are industrial PCBs different than commercial PCBs?
Industrial PCBs differentiate by:
· Supporting wider operating temperatures (-65°C to +150°C)
· Longer field deployment lifetimes (10-20 years)
· Required survival through harsh vibration, shock, moisture
conditions
· High availability and uptime (>99%)
· Rigorous product testing and qualification
· Precision manufacturing process controls
· Traceability documentation Which exceeds commercial PCB
environmental and lifespan demands.
Why is FR-4 still commonly used if industrial PCBs face extreme
temperatures?
While special substrates like polyimides and ceramics handle wider
temperature swings, FR-4 laminates have evolved “high Tg” versions
usable to 150°C+ along with lower cost and better fabricator
familiarity. So FR-4 remains an option for many industrial
applications not hitting extreme temps.
IPC Class 3
Issued under IPC-2221 standards, it covers generic performance
requirements for industrial electronics printed boards especially
related to:
- Temperature cycling (-65°C to 150°C)
- Vibration (10-500Hz at 10G+)
- Mechanical shock of 100-1500G
- Moisture resistance
- Other environmental stresses
Additionally covers recommended test methods, quality conformance
criteria and inspection details useful for qualifying Class 3
boards. It represents a minimum level for most industrial
applications.
