Anyone here done an integrated planar transformer before? By integrated, I mean that all the windings are on your main PCB, instead of having a separate PCB for windings. My PCB is already going to have 8-10 layers, so this seems like an effective way to minimize cost and size. Also the core materials I'm interested in using tend to be in planar shapes, as opposed to RM sizes.
The issue is mass assembly. I can find practically no resources on how this is done for integrated transformers. The type of cores I want to use (EQ25) don't even offer spring clamps/clips from the manufacturers. Most suggestions I find are either "just glue the things together," or suggest clamping it with custom mechanics. Both sound labor intensive (and introduce possibility for poor yield), and the latter introduces additional costs. I'm concerned about vibration in my application as well, and can't find any real discussion of this.
Anyone have any experience to share on this?
