Solder Profile

The soldering profile depends on various parameters necessitating a set up for each application. The data here is given only for guidance on solder re-flow. There are four zones:
1. Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-2.5°C/s.
2. Equilibrium Zone - This zone brings the board to a uniform temperature and also activates the flux.
The duration in this zone (typically 2 -3 minutes) will need to be adjusted to optimize the out gassing of the flux.
3. Reflow Zone - The peak temperature should be high enough to achieve good wetting but not so high as to cause component discoloration or damage. Excessive soldering time can lead to inter-metallic growth which can result in a brittle joint.
4. Cooling Zone - The cooling rate should be fast, to keep the solder grains small which will give a longer lasting joint. Typical rates will be 2-5°C/s.

General Description

The BT 44 – 147 is a general purpose Bluetooth module incorporating an on-board
meandering line antenna designed to be incorporated into an end product. The BC04
Bluetooth Module is a Class 2 Bluetooth module using BlueCore4-External chipset from Cambridge
Silicon Radio, a leading Bluetooth chipset supplier. It provides a fully compliant Bluetooth system
for data and voice communications. Interfaces with a host via UART (USB optional) and supports
EDR data rate up to 3Mbps modulation modes. The module and device firmware is fully compliant
with the Bluetooth specification V2.0.
