Using the evaluation sequence shown in Section 3.3:
c12x2
= c12 * Tadc
= 0.00086665 * 513
= 0.44459
a1
= b1 + c12x2 = -2.49512 + 0.44459
= -2.05052
a1x1
y1
a2x2
= a1 * Padc
= a0 + a1x1
= b2 * Tadc
= -2.05052 * 415
= 2107.875 + (-850.96785)
= -1.02069 * 513
= -850.96785
= 1256.90715
= -523.61444
PComp = y1 + a2x2
= 1256.90715 + (-523.61444) = 733.29270

Solder Recommendations
Use SAC solder alloy (i.e., Sn-Ag-Cu) with a melting point of about 217°C. It is recommended to use SAC305
(i.e., Sn-3.0 wt.% Ag-0.5 wt.% Cu).
Reflow
?
?
?
?
?
?
Ramp up rate: 2 to 3°C/s.
Preheat flat (soak): 110 to 130s.
Reflow peak temperature: 250 ° C to 260°C (depends on exact SAC alloy composition).
Time above 217°C: 40 to 90s (depends on board type, thermal mass of the board/quantities in the reflow).
Ramp down: 5 to 6°C/s.
Using an inert reflow environment (with O 2 level about 5 to 15 ppm).
NOTE: The stress level and signal offset of the device also depends on the board type, board core material, board thickness
and metal finishing of the board.
