| Yes, just wish I could figure out how they are controlling the heaters. In standard mode you need the top and bottom TC's, so is it maintaining temps for you? The graph seems to somewhat try to run the profile. This machine may actually be idiot proof, yeah I wish. On one practice run the componets started dropping off the bottom of the board. Never had that issue with the RE7500.
So my main question, which Jovy hasn't answered, is do you start the profile with the upper heater lowered? Seems that is how it works since there is no prompt to move the heater like with the RE7500. Then the follow up question is do you leave the upper heater in place until the profile finishes?
If the RE8500 just runs an entire profile while you just mount the board and lower the upper heater, that would make it sort of an automatic process for a simple reflow. But then that doesn't take into account when you have to remove a BGA. What do you do then? set the alarm to the liquidus temp them get the upper heater out of the way then pull the chip and then what? Cancel the profile and turn the fan on?
See my point on so many unknowns! |
