Reflow welder will not heat the cause of the failure analysis, touch screen and OLED forum
Reflow soldering products are adjusted according to the temperature curve of reflow soldering to achieve better reflow soldering effect. Reflow soldering temperature curve can directly reflect the soldering temperature change process of circuit board in reflow soldering furnace. It is easy to weld according to the reflow temperature curve. Cause a lot of bad reflow soldering products J2 B3 T( l$ NThe reflow welding machine will not give a heating fault alarm.
