Key Criteria for Lead-Free Reflow Oven Process
Temperature Control & Uniformity
You need to control the temperature very carefully. Lead-free soldering needs higher heat than leaded soldering. There is less room for mistakes. The process window is often only 8°C wide. If you do not keep the right temperature, you can get defects. You might even damage your boards.
โซนอุณหภูมิ | ช่วงอุณหภูมิ (°C) | Duration (seconds) |
|---|---|---|
Preheating Zone | 140-150 | – |
Constant Temperature Zone | 150-200 | 60-120 |
Reflux Zone | Above 217 | 40-90 |
Cooling Area | Less than 1-4 | – |
It is important to heat everything evenly. If the oven does not heat the same everywhere, you can get problems. You might see solder beads, voids, or weak joints.
