General purpose Bluetooth systems requiring an
on-chip audio CODEC
BlueCore6-Audio ROM has been designed to reduce
the number of external components required which
ensures production costs are minimised.
BlueCore6-Audio ROM includes AuriStream, which
offers significant power reduction over the CVSD
based system when used at both ends of the link.
The device incorporates auto-calibration and
built-in
self-test
(BIST) routines to simplify development, type
approval and production test. All hardware and device
firmware is fully compliant with the Bluetooth v2.1 +
EDR specification (all mandatory features).

2.4 PCB Design and Assembly Considerations
The following list details the recommendations to achieve maximum board-level reliability for BlueCore6-Audio ROM:
■
Non-solder mask defined
(NSMD) lands (lands smaller than the solder mask aperture) are preferred,
because of the greater accuracy of the metal definition process compared to the solder mask process. With
solder mask defined pads, the overlap of the solder mask on the land creates a step in the solder at the
land interface, which can cause stress concentration and act as a point for crack initiation.
■
PCB land width should be 0.3mm and PCB land length should be 0.9mm to achieve maximum reliability.
■
Solder paste must be used during the assembly process.
2.5 Typical Solder Reflow Profile
See
Typical Solder Reflow Profile for Lead-free Device
for information.
