Can anyone tell me where I can get PCB mount (i.e. thru-hole) copper fingers

Hello,

Not strictly RF/microwave, as it's more EMC, but this is obviously something important in RF/microwave so hopefully someone here will know the answer.

I am looking for a simple way to construct PCB shielding cans. I need the cans to be quite large and tall, and I would rather not cut out copper sheets by hand and fold - done this before and while it works, it is time consuming. My quantities are too few to outsource this as well unfortunately. I was considering attempting to create a die and draw using an arbor press, but I'm not sure how easy this will be and whether it will actually be a good shield. Then I remembered this:

A few ago I was given some Tx/Rx switches that have a simple PCB mounted shield on them. It consists of some board mounted copper fingers, and a single sided piece of copper clad FR4 for the lid. This would be ideal for me, but I cannot find where that stocks the copper fingers. Can anyone help me. Some images below:

This is the Tx/Rx switch - it's a shielded enclosure made from the copper fingers and sides of FR4. The bottom side of the FR4 has a microstrip circuit on the inside.

Here's a close-up of the copper fingers.

Much ta!

Nickle-tin plated brass shields/lids can be purchased in std sizes for PCB's from several suppliers.

I recall many suppliers and also DIY at work using tin plated brass, etch-folded and soldered gaps for proto's.

Consider a tin-dip plated brass box with edge receptacles **broken link removed**

This is just one of many sources.

Thanks. I've used the harwin shield clips before, along with a folded copper box. Was looking into alternatives, otherwise that's what I'll do again as it worked, despite taking some time.
 

Hi.

Don't know if these are any use (maybe the wrong thing or not high/tall enough for your needs), all are tin-plated steel, look easy to implement (drilling two or a few holes in a pcb by the look of it), apparently also "Promotes high yield on reflow soldering":
