Does anybody have a slick way to hold down large inductors? Like 2 to 3 inches in diameter. There must be something better than ty-wraps and RTV.

Possibly a retention clip that would snap into the board?

We already tried that. The sugar seems to have a bad reaction with the varnish on the Inductors. Do they make a sugar-free version?? Can you send me some samples??

SMT adhesive? Might be able to cure in wave process?

It is quite common for this to be done with an activator cured acrylic adhesive (eg, Dymax, Loctite, Permabond). This method took over from mechanical clips and epoxy some years ago because using: * Mechanical clips changes the magnetic circuit. * Epoxies and other adhesives with a large polymerised molecule creates gaps in the magnetic circuit, thereby reducing the inductance.

DaveF, would the adhesive be strong enough to keep the part from vibrating free over time? DO you know any part numbers? These inductors have quite a high mass. I would profer to lay them down on thier side but there is not enough room.

The materials suppliers mentioned above (eg, Dymax, Loctite, Permabond) have applications types that will recommend products to meet your requirements.

Can I get a sample of the Bubble Yum? Do you have several varieties?
