3:22 : so regular soldering temperatures of around 200 °C far exheed FR-4's glass transition temperature. How come regular soldering and hot air reflow don't impact PCB quality?
The glass transition temperature (Tg) of FR-4 is indeed lower than typical soldering temperatures. However, the short duration of the soldering process, combined with the thermal mass of the PCB, prevents significant damage to the FR-4 material.
so much like and thank you for the time 👌👍💯💯💯

@@PCBWay thank you for the explanation
🙏👍🙋♂💐

I do like the video tho ;D
