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!
