Who sells RF shield cans?

Apr 03, 2007 51 Replies

Where can one buy those tin-plated RF shields with snap-on lids? The stuff modern TV tuners are using but for circuit board mounting (meaning open frame with solder pins). One to two square inches, no more than



1/2" high (because it must go onto VME boards). If it doesn't have a lid but is permanently closed after soldering that would be sort of ok as well.

Things is, we don't need a million per month so the usual metal shop order is out. Of course I know we could also buy and eat pounds of Altoids to get those cans but I guess that might result in stomach aches.

Joerg,

These parts are custom in all applications where we have used them. Never seen a COTS part of this sort. Have you considered buying and recycling some canned module; RF modulator, tuner, etc?

As a data point, Jameco part 141639 is $1.74 in 10pc, which is rather expensive - I expect you can find it for

(Laird hired an idiot who made a page with JavaScript'd Flash content.)

That's what I was afraid to be the case. Maybe we'll just do a series at the local machine shop and then offer it to Digikey :-)

Thanks, Lewin. It's a bit high for VME, might scrape the neighboring board. Butchering these is almost as much work as rolling my own though. I've done it for the prototype. Nice shiny copper, looks really posh. But we can't do that in the final version, copper thiefs and all that ;-)

Excellent! That's exactamente what I was looking for. Many thanks. In case someone else has a similar need this is the direct link:

Don't know Laird. But when I look at the rapid pace at which major corporate web sites slide down the hill I have the impression that the script kiddies have made it into the corporate cubicles :-(

Maybe it's time that Scott Adams introduces Dotnetbert and Flashbert.

has some. I don't know if they are on the website. I pick these things up from time to time at surplus shops since they are relatively cheap (i.e. a quarter) and once in a while come in handy.

Come to think of it, the ones Halted has are meant for soldering to the PCB.

Joerg: fotofabrication also sells some that are available in flat sheets with score marks for varying heights. You can break off sections for prototypes, but I think they are all 5 sided - no removable lids, and no through-hole solder tabs

If you want custom made (but small orders are not too pricey) take a look at:

It takes a true Usenet idiot to copy someone's sig when quoting.

Thanks, Steve. Seems like you can get them in a size to cover the whole circuit board. Very nice.

Couldn't see any on their web site. We have a Halted here in Sacramento but it's pretty small and I always dread the long drive into town. But it certainly is an option if the others turns us down because of MOQ. First we just have to built some prototypes, a dozen or so.

And an article on shielding, just because it was in the same file.

Let's see ... 12 shields at 25 cents a pop. That $3, oh, but $20 for the gas.

I do like to support Halted just to keep them in business. These surplus stores are becoming extinct thanks to the net and ebay. No more Haltek, RA, Just-In-Time, and maybe one or two more I can't recall.

Ace is still in business (according to the website)

Hey, how did you know I exactly needed that *now*?

Thanks for the link.

Thanks, Fred.

Any of them with any brains at all sell on E-bay as well.

Are these guys any use? They do low-volume stuff as far as I recall.

Oh, please forgive me, master Prong. I humbly implore your indulgence for giving assistance in such an unworthy manner. Perhaps if I had access to the mystical Book of Prong, I would understand my weaknesses and be able to participate correctly in enlightened technical interchange with those so much more knowledgeable than myself.

Most humbly, Steve
