Our design consists of general principles related to shielding, grounding, by passing, and keeping conductive material from the iPhone antenna area. We have also taken special consideration to ensure that all our electronic products built for the iPhone are custom shielded to eliminate TDMA noise when in used.

Our PCB and electronic wiring are shielded with special cooper wrap to help eliminate RF interference from the iPhone. A special integrated chip (IC) is used in conjunction with the audio pin outs to lower the TDMA noise on all iPhone speakers and sync and charge dock products.
