Expert Printed Circuit Board Thermal Management and Metal Cladding
Electronic Interconnect – The PCB Experts
Electronic Interconnect is a reliable manufacturer of high quality PCBs – up to Class 3. We specialize in and focus on the design and manufacture of PC boards.With nearly 30 years of experience, our customers have benefited from our unique technical advancements and distinct advantages, such as thermal management, use of metal cladding, heavy copper and outstanding solder-ability.
Effective Use of Thermal Management
Today, many PCB materials, constructions, and configurations for electronic assemblies require special thermal management to ensure continued operation without excessive heat issues, such as- Hot spots
- CTE mismatch
- Solder joint stress
- Thermal fatigue failure
- Shock and vibration issues
While thermal management is important for any electronic assembly that is smaller, faster and stronger, it has become a critical part of PCB design for:
- High-power devices
- RF and wireless applications
- LED lighting boards
- DC/DC converters
- Electric motor controls
Thermal Management Expertise
As PCB specialists, we have become experts in the use of metals and Thermal Management. As a result, our PCBs exhibit faster heat dissipation, longer life and reduced energy needs. Our heat management capabilities include UL-certified metal-clad PCBs with various thicknesses of dielectrics and metal bases, such as aluminum and copper.Materials Expertise
The combination of our knowledge and dedication to thermal management in PCBs, our expert processes and the use of many thermal laminates, allow us to optimize the performance and reliability of metal clad PCBs and provide the best solution to our customers. We manufacture boards with optional metal bases, provide metal cladding and use heavy copper weights.Electronic Interconnect offers design counseling services to support the Thermal Management program.

PowerLink PCBs (PLPCBs) with Heavy Copper
There are multiple benefits of PLPCBs, ranging from smaller PCB size to extended life. They utilize a minimum of two copper weights on the same layer for the buss bar application.- UL approved up to 6 oz.; capabilities to 20 oz.
- Use of multiple copper weights on same FR4 plane
- Prevents circuit failure
- Reduces number of connectors required
- Increases mechanical strength
- Higher current carrying capacity
- Use of high temperature dielectric material
