Case Studies
Frequently Asked Questions
A: Yes, MCPCB is also known as IMS (Insulated Metal Substrate). They are essentially the same, with different naming conventions.
A: Common materials include aluminum and copper. Aluminum is the most widely used due to its balance of cost and performance, while copper is suitable for higher power density applications. In some special cases, stainless steel or customized metal alloys may also be used, though less common.
A: Metal core typically refers to a PCB structure that includes a metal base within the board, while metal-backed PCB usually refers to a structure where an additional metal layer is attached to the back of the PCB for heat dissipation.
A: Thermal performance mainly depends on the dielectric layer. Standard aluminum-based MCPCBs typically offer thermal conductivity of about 1–4 W/m·K, while copper-based solutions can reach approximately 3–5 W/m·K.
A: For mechanical drilling, the minimum hole size on metal substrates is typically around 0.2 mm. Smaller holes require laser drilling, which is more challenging due to the presence of the metal layer and must be evaluated based on the specific design.
A: Current-carrying capacity depends on copper thickness, trace width, and thermal design. Thick copper structures (such as 10 oz and above), combined with proper layout, can support high-current applications such as power modules and power electronics systems.
A: Yes. This is typically achieved using a metal-backed structure combined with high-frequency materials such as Rogers or Taconic, enabling both effective heat dissipation and RF performance in a hybrid design.
A: MCPCB manufacturing is more complex, especially in drilling metal layers, which leads to higher tool wear and longer processing time. In addition, material costs and yield control requirements are higher.
A: Yes, we offer one-stop services from bare board manufacturing to full PCBA assembly. Whether it is consigned assembly or turnkey solutions, we can support based on your project requirements.
A: Yes. At the early stage of the project, our engineering team can provide DFM analysis, thermal design optimization suggestions, and material selection support to reduce risks and improve reliability.
A: Yes, we have the capability to manufacture thick copper MCPCBs, supporting up to 33 oz copper thickness, suitable for high-current and high-power applications.
A: Due to the complexity of MCPCB manufacturing, lead time depends on the design structure and process requirements. For urgent projects, expedited services are available upon evaluation.
A: Simply provide Gerber files, BOM list, or technical requirements. Our team will quickly complete engineering evaluation and provide a quotation along with optimization suggestions.
