3.2. Soldering Profile
Solder paste : Sn/Ag/Cu:96.5/3.0/0.5
This product is designed for reflow soldering only. Do not use flow (wave)
soldering.
① Use non-activated flux (Cl content 0.2% max.)
② Follow the recommended soldering conditions to avoid damage.
③ Reflow-cycle is max. 3 times.
MAIN CHIP ANTENNA
4. Manual pattern tuning
FR4 is used for this antenna. The frequency of the antenna is shifted by the tolerance of FR4
thickness and dielectric constant, so manual pattern tuning is needed for frequency matching.
