Reflow discoloration is generally resistant plastic stand about 270 degrees C temperature, where you can reflow-resistant plastic, such as PPA, etc.
According to the experience of our factory, we adopt HTN2GF30 this material reflow temperature is set at 260-270 degrees, no significant discoloration.
The main reason is not discolored plastic to withstand high temperatures, oxidation at high temperatures, so the color will turn yellow, or black.

回流焊变色一般是塑料耐受不了270度左右的温度,这里你可以采用耐回流焊的塑料,如PPA等
根据我们厂的经验,采用HTN2GF30这款材料我们回流焊温度设定为260-270度,未有明显变色。
变色的主要原因是塑料不耐受高温,在高温下氧化了,所以颜色会变黄,或变黑。
