3.7 Recommended Guideline for PCB Assembly
z Recommended vender and type for Pb-free solder paste
1. Almit LFM-48W TM-HP
2. Senju M705-GRN360-K
z IR Reflow Soldering Profile:
Temperature profile is the most important control in reflow soldering. It must be fine tuned to
establish a robust process. The typical recommended IR reflow profile is showed in figure 8
below.
IR Reflow Profile
Reflow Profile :
1. Average Ramp-up Rate (30°C to preheat zone): 1.5~ 2.5 Degree C/ Sec
2. Preheat zone:
2.1
Temp ramp from 170~ 200 degree C
2.2
Exposure time: 90 +/- 30 sec
