| RF can apertures - RF Cafe Forums | ||||||
|
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. matt Post subject: RF can apertures Unread postPosted: Tue Jan 18, 2005 8:39 am I would like to calculate the maximum aperture size in a RF can to prevent RF energy @2.4GHz radiating through the can. The can material is brass nickle plate fixed to a FR4 pcb. I currently have apertures of 0.3mm X 2.5mm spaced along the bottom wall edges to thermally relieve the pcb contacts of the can. Is this OK? I have been told aperture dimensions should not exceed 0.6mm square before RF @2.4GHz sees the "gap" - in which case my existing can would fail to block the RF. Can anyone please advise?
