3M 的 ECM 规格书

Utilize a Proven Solution
• A UL certified and RoHS2 compliant laminate with high capacitance
density that can be embedded into PCBs and chip packages as either a
power ground plane or a discrete capacitor
• Consists of a very thin layer of ceramic-filled epoxy sandwiched between
two layers of copper foil
• Compatible with a large range of PCB material sets and with standard
PCB fabrication and assembly processes, including lead-free
• Halogen-free3 versions available along with a variety of panel sizes and
copper thicknesses
• In production in telecom, computer, test and measurement, military/
aerospace, medical and consumer electronics applications
Simplify Design while Amplifying Performance
• Increases usable board area by allowing for the removal of many, if not
all, capacitors equal to or below 0.1 µF and their associated solder joints
and vias
• Improves power integrity by reducing power bus noise and PCB
impedance
• Reduces EMI by decreasing resonance that causes EMI
• Dissipates heat better than thin FR-4 due to high thermal conductivity
and low thermal impedance
Enable Product Roadmaps
• Simplify board layout and routing
• Reduce PCB size, thickness and weight
• Add functionality on fixed form factors
• Lower spreading inductance
• Decrease need for EMC measures such as metal shells, tapes, etc.
• Reduce interference from digital circuits to analog/RF circuits in mixed
signal applications
• Add PCB layers while maintaining similar PCB thickness
• Reduce design spins by solving noise issues early in the design cycle
• Improve PCB panel utilization
• Improve assembly yields and board reliability due to fewer components
