Frequently Asked Questions
What is an Insulated Metal Base Printed Circuit Board (IMS PCB)?
An Insulated Metal Base PCB (IMS) is a thermal management board featuring an aluminium or copper substrate base. It is bonded to the circuit layer using a specialized thermal dielectric pre-preg or resin system, allowing for superior heat dissipation compared to traditional FR4 boards.
What are the thermal conductivity options for AREX IMS PCBs?
AREX offers highly efficient thermal solutions with a thermal conductivity range of 1 to 12 W/m/K, depending on the dielectric materials and application requirements.
What materials and layer counts are available for these metal core PCBs?
We manufacture IMS PCBs with 1 to 4 layers. The primary base materials include high-quality aluminium and copper plates, combined with FR-4, PTFE, and high-performance thermal dielectrics.
What are the typical applications for IMS PCBs?
Due to their excellent mechanical strength and heat dissipation, they are widely used in computer brushless DC motors, high-performance floppy disk drives, automatic camera motors, and advanced military technology products.
What surface finishes and profiling options do you support?
Available surface finishes include HASL, Lead-Free HASL, OSP, ENIG, Immersion Tin, and Immersion Silver. For profiling, we support both punching and liquid-cooled routing methods.
