Newest/most progressed thinnest way to put ferrite





April 18, 2012

Q. Hi,

I'm Arye Nudelman HW Engineer.

I would to ask you if next paragraphs info is part of your company service.

I'm doing a research and optimization for the Newest/most progressed thinnest way to put ferrite that it will have thinnest layer, lower that 0.1 mm on PCB/flex.
For example to grow it on the copper instead of the solder mask/ cover layer of the circuit that shall cover our PCB/Flex planer coil, or ITO, spin spray, coating, etc.

As first step we would like to manufacture prototypes while final step is mass production of 1-5 million units per year.
Currently implemented ferrite 0.4 mm is with the following parameters:
Saturation flux density: 0.49T
Permeability: 2400u
Operation frequency: 100-500KHz

If you see your company may be suitable for this issue I would be glad to have an initial technical discussion regarding the project.

Example of desired design that shall be even thinner

ferrite layer  ferrite        40    um
Plating Copper 15 um
PTH Copper L1 FCCL 18 um
Polyimide 12 um
Copper L2 18 um
Plating Copper 15 um
total 118 um


Thanks and best regards,
