SQPCB (Shuoqiang Electronics) is one of the few manufacturers capable of producing Thermo Electric Separation PCBs. With specialized equipment, advanced processes, and deep technical know-how, SQPCB helps customers overcome the limitations of conventional PCB thermal designs.
Let’s begin with thermal conductivity.
Copper has an impressive thermal conductivity of about 360 W/m·K, making it one of the most effective materials for heat transfer.
However, in conventional aluminum-based or copper-based PCBs, there is always an insulating dielectric layer between the copper and the heat-generating device. This insulating layer typically has a thermal conductivity of only 1–2 W/m·K.

This creates a major bottleneck: copper can transfer heat efficiently, but the insulating layer blocks most of this ability.

Thermo Electric Separation PCB solves this problem. By allowing the heat source to come into direct contact with copper, it eliminates the thermal resistance of the insulating layer, leading to faster and more efficient heat dissipation. For industries where every degree matters, this innovation makes a significant difference.
Producing Thermo Electric Separation PCBs is not something every factory can do. The complexity lies in both the process and the precision required:
Complex Structural Design – The PCB must achieve both high thermal conductivity and electrical insulation, while preventing short circuits.
Thermal Expansion and Dimensional Stability – Large copper surfaces tend to expand and contract during thermal processes, creating alignment challenges.
Strict Equipment Demands – Standard exposure machines, drilling machines, forming machines, and testing equipment are often limited by size and accuracy, making it difficult to handle this type of PCB.
SQPCB has made significant investments in advanced equipment to overcome these barriers:
LDI inline automatic exposure machines for circuit imaging.
LDI inline automatic exposure machines for solder mask.
Inline automatic text-spraying printers.
These upgrades eliminate common issues such as film expansion, misalignment, manual handling errors, scratches, and rework. They also guarantee solder mask gloss and improve overall product yield. Additionally, SQPCB operates its own lamination, HASL, and ENIG finishing processes, giving them complete control over quality and delivery timelines.
Thermo Electric Separation PCBs are essential in industries where high-power devices generate significant heat:
LED Lighting: High-power LED chips generate considerable heat. With direct copper contact, Thermo Electric Separation PCBs improve heat transfer, extend product lifespan, and ensure stable brightness.
Power Modules: High-frequency, high-current converters need advanced thermal management to maintain performance.
Automotive Electronics: Electric vehicles rely on power modules and control systems that demand high heat resistance and long-term reliability.
Industrial Equipment: Servo drives, inverters, and automation systems all require stable and efficient heat dissipation.
SQPCB doesn’t just provide PCBs—it delivers reliability through complete in-house process control. Their strengths include:
In-House Lamination – Ensures dimensional accuracy and reduces warpage.
In-House Surface Finishing (HASL & ENIG) – Guarantees long-term performance and solderability.
Advanced LDI Exposure and Inkjet Printing – Enhances product quality while reducing defects and rework.
