'IR receivers and their reflective containers?'

Hi,
I have a project that I am currently using a Liteon IR receiver in a little
metal can,
similar to the one we all se in consumer electronics.  I am short on front panel
space and am considering mounting the IR reciever on the PC board with the
associated IC.  Can someone tell me how critical the can is?

Thanks,

They used to be very critical, but I forget the reason!

One big reason is electrostatic/electromagnetic shielding. Without a shield
the circuit is next to useless.

The gain in the amp is quite high. Have you ever noticed how easy
it is to trigger a cheap commercial passive infrared detecter with a
powerful radio transmitter? The can acts as a shield against this.
