I've been reading about FR-4 TG-135, TG-150 and TG-170 if those codes stands for 135°C, 150°C and 170°C while operating, my doubt is, when it's time to reflow the temperature could be somewhere between 200-260°C, so does PCBs release halogen gases during reflow time?

My concern it's because I plan to reflow some boards in my house instead order PCBA.
