Using ANSYS-based thermal and CFD simulation, engineers can evaluate heat generation, conduction, convection, airflow, component temperatures, and cooling performance across electronic assemblies.
At SolidTrust Technologies, thermal and multiphysics simulation can support electronics design, cooling optimization, and simulation-driven product validation.
What Is PCB Thermal Analysis?
PCB Thermal Analysis is a simulation-based engineering method used to predict how heat is generated, transferred, and dissipated across a printed circuit board and its electronic components.
Electronic components such as processors, integrated circuits, power regulators, LEDs, MOSFETs, memory devices, and power modules generate heat during operation. Therefore, engineers need to understand how that heat moves through the PCB, components, thermal interfaces, heat sinks, and surrounding air.
PCB thermal simulation can evaluate:
- PCB temperature distribution
- Component temperature
- Thermal hotspots
- Heat flux
- Heat transfer
- Airflow
- Natural convection
- Forced convection
- Heat sink performance
- Thermal interface performance
- Cooling efficiency
- Transient temperature behavior
- Thermal stress and deformation
Consequently, PCB thermal analysis provides engineers with valuable information for improving electronic product reliability and cooling performance.
Why Are PCB Thermal Analysis Services Important?
As electronic products become smaller and more powerful, heat generation can increase significantly within a limited physical space.
Therefore, thermal analysis should become part of the design and verification process.
1. Identify Thermal Hotspots
Thermal simulation helps identify components or PCB regions where excessive temperatures develop.
As a result, engineers can modify component placement, cooling paths, copper distribution, or heat sink configurations.
2. Improve PCB Cooling
Thermal analysis helps determine how efficiently heat moves from high-power components into the PCB and surrounding cooling system.
3. Optimize Component Placement
Component arrangement can strongly influence thermal performance. Simulation allows engineers to compare different PCB layouts and identify better thermal configurations.
4. Improve Electronic Reliability
Excessive temperature can negatively affect electronic component performance and durability. Therefore, identifying thermal problems early can support more reliable product development.
5. Reduce Prototype Iterations
Instead of depending entirely on physical prototypes, engineers can evaluate multiple thermal designs virtually before manufacturing.
6. Support Design Validation
Thermal simulation can complement structural, CFD, and multiphysics analysis during product development and design verification.

However, simulation and testing work best together. Simulation can guide the design, while physical testing can validate the final hardware.
PCB Thermal Hotspot Analysis
Thermal hotspots are one of the most important issues in high-density PCB designs.
For example, processors, power regulators, MOSFETs, LEDs, and power modules may generate significant localized heat.
Thermal simulation can show exactly where these temperatures develop.
Engineers can then investigate solutions such as:
- Moving high-power components
- Improving copper heat spreading
- Adding thermal vias
- Increasing heat sink capacity
- Improving thermal interface materials
- Adding airflow
- Changing fan placement
- Improving enclosure ventilation
Therefore, PCB thermal analysis can support both board-level and system-level thermal optimization.
PCB Thermal Design Optimization
Thermal analysis becomes even more valuable when engineers use simulation to compare multiple design configurations.
Important design variables may include:
- Component placement
- Copper distribution
- Thermal vias
- PCB material
- Heat sink geometry
- Fan flow rate
- Fan position
- Vent locations
- Thermal interface materials
- Enclosure geometry
By comparing these variables, engineers can identify a design that balances thermal performance, size, weight, cost, and manufacturing requirements.
Multiphysics PCB Thermal Analysis
Modern electronic products often involve multiple physical effects.
For example, electrical power generates heat. Then, heat moves through the PCB and components. At the same time, airflow removes heat from the system.
Furthermore, temperature changes can cause thermal expansion and structural deformation.
Therefore, multiphysics simulation can provide deeper insight into complex electronic systems by considering thermal, fluid, structural, and other interacting effects.
