WebReflow oven zone temperature is a set point where the heat element will be heated to reach this temperature set point. This is a closed loop control process using a modern PID control concept. The data of hot air temperature around this particular heat element will be fed back to controller, which decide to turn on or off the heat energy. WebThe process of hot air reflow soldering is essentially a heat transfer process. Before starting to “cook” the target board, the reflow oven zone temperature needs to be set up. Reflow …
WebThe rate of temperature rise (ramp rate) will determine the duration of reflow from start to finish. This is directly proportional to the input temperatures set on the profile. In this case the ramp rate is 0.5 C per second. Graph of ramp rate at 0.5 C/Sec Total time to achieve reflow 20 seconds Solder temperature Liquid 217 C T 10 C Solid WebYou will need: 1. Reflow source (reflow oven, hot air system, IR system) 2. Paste flux (water soluable is preferred) 3. Soldering iron w/blade tip 4. Braid/Wick 5. Kim wipes 6. Water and soft brush for cleaning 7.
