SD Card Reader Hot Air Removal ST 350

This is a short demonstration on how to remove an SD Card Reader from a Galaxy S5 (Not an S6!) circuit board using Hot Air and Secondary Heating. The PCB contains an array of heat sinking and shielding components that make an otherwise simple removal, much more challenging.
The procedure was as follows:
1. Install the PCB into the ST 350 board holder. For minimal interference, use the special clamps to hold the board in place.
2. With an ST 400 Preheater, preheat the board on 150-180C for 3 to 4 minutes.
3. Once the board is hot to the touch or exceeds 100C, input a profile to ST 350. Ideal parameters are: 100-120 Seconds, Blower Speed 7-9, Temp of 750-775C.
4. Before starting the heating cycle, place a generous amount of liquid flux on the component. The more the better! Tacky flux would also be acceptable for this process.
5. Lower the nozzle to the component as close as possible, but not touching.
6. Commence the cycle. NOTE Due to this component's particular dimensions, the vacuum cup inside the nozzle head may fail in picking up the component once reflowed. Be sure to align the component to the vacuum cup as best you can. If not, use the handheld vacuum pick as demonstrated in this video.
7a. At the end of the cycle, the vacuum pick will engage automatically and grab the component. At this point, raise the heater head from the board.
7b. If the vacuum pick fails to pick up the component, use the handheld Vacuum Pick to lift the component from the board.
8. Once cool, remove the board from the board holder and clean off any flux residue before removing excess solder from the pads.
Thank You.

How about I have the st 350 work machine and I would like to see a complete video tutorial of Sun, you explained it well if you can

775 F? Are u sure? Amazing temp

What is the name of the flux that your used here?

I'm sure a lot of subtle features from this system would stop working quite soon. The vacuum pick is already defective while it's still in the factory. Why include features that won't last. Why not keep it the old school way and let things work for a long time?

4.12 you push down your PCB. Hmmm not that good way to rework...

I tried to give the vacuum pick another chance at grabbing the component. Should of just gone straight to the handheld pick.

YOU PUSHED DOWN.
