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.
What does PCBA Stand for in Electronics?
PCBA stands for Printed Circuit Board Assembly. It refers to the
process of soldering electronic components to a printed circuit
board (PCB) to create a functional circuit. The PCB is essentially
the backbone of electronic devices, providing a solid foundation
for components and facilitating connections between them. The
assembly process involves soldering components to the board, and
this completed assembly is then referred to as PCBA.

How are industrial PCBs different than commercial PCBs?
· 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.
What are some ways engineers design industrial PCB layouts
differently?
Design techniques used for industrial printed circuit boards
include:
- Component derating below absolute maximum levels
- Thermal simulation using finite element models
- Redundant connections and pathways
- Vibration damping edge mount connectors
- Conformal coating for moisture protection
- Thicker power and ground traces
- Double sided boards to withstand shock
- Extensive DFM analysis before release
