REFLOW PROFILE GUIDELINE

Communicate with the sincere and open world!!

Notes:

1. Reflow profile guideline is designed for SnAgCulead-free solder paste.

2. Reflow temperature is defined at the solder ball of package/or the lead of package.

3. MTK would recommend customer following the solder paste vendor’s guideline to design a profile

appropriate your line and products.

4. Appropriate N2 atmosphere is recommended since it would widen the process window and mitigate

the risk for having solder open issues.

users

2) This device and its antenna(s) must not be co‐located with any other transmitters except
in accordance with FCC multi‐transmitter product procedures. Referring to the multi‐
transmitter policy, multiple‐transmitter(s) and module(s) can be operated simultaneously
without C2P.

3) For all products market in US, OEM has to limit the operation channels in CH1 to CH11
for 2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info
to the end‐user regarding to Regulatory Domain change.

USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at
least 20cm separation with the antenna while this end product is installed and operated.

The end user has to be informed that the FCC radio‐frequency exposure guidelines for an
uncontrolled environment can be satisfied. The end user has to also be informed that any

changes or modifications not expressly approved by the manufacturer could void the user's
