FIELD SERVICE BULLETIN

FSB Number: LVCCFSB2004-0035
Author: Leo Ramos
Date: February 18, 2004
Total No. of Pages: 2
Subject: Bluetooth Headset No Power Up
Model Affected: All HS810 Bluetooth Headset (SYN9826A)
Level of repair: 1

Scope

Units are being returned from the field with a high OOB failure rate for units that will not power up after
charging.

Problem

When units are taken out of the box and plugged into a power supply to charge, the blue charging light
illuminates and turns off in approximately 90 minutes signaling that the battery has charged. However,
units will not power up after the charge cycle is complete.

The issue first surfaced in late November. The root cause is a quality problem with the PCB fab which
was improved in Wk 49, 2003. The failure analysis shows cracked micro-vias connecting the BC2 chip
with the flash memory. The micro-via failure occurs after the manufacturing process and could not have
been detected with normal production testing.

Solution

PCB process improvements were implemented in WK 49. All suspect units are being returned to the
manufacturer for screening.

Additional corrective or preventative actions may be put in place pending results from the ongoing
analysis
