How To Reflow Solder With A Heat Gun

Dumb question whats a preheater.

How to reflow solder with a heat gun. If I sent it off to be done for 400 I was concerned the problem would happen again down the road. And might not be possible depending on the hiardrier. Often times people heat up the chip without removing it and still seem to successfully reflow.

Well not likely -you would damage the chip before you get solder balls to melt - even when removing old solder you should not stay in one place with your soldering gun for longyou should move it constantlyChip will be damaged 220 C and melting point is 213-217C so when using heatgun still pre-heat the board approx-100C use flux and bake board before reflow. A 6 pin WLP like that is easy relatively to solder to with some spare wire as there would be no overlapping. So my question is.

After solder mixture process preheat the board close to 200C and continue with hot air station. Is this a safe substitute to a reflow oven for a one time job. There are other solutions you could try like a toaster oven converted for soldering or a pan etc etc but if you need to do multiple a proper hot air soldering station is used.

After this I slowly back out in the same procedure as before. I figured I had nothing to lose to try to reflow the board myself. Hot air reflow work must be carried out with b.

A real reflow oven. Clearing Bridges from Pins 1-8 and 9-16 of New U1. To add a single new component to the board first place some solder paste on the component.

Youll find a decent write up about a good procedure right here. Another consideration is the air stream from a heat gun is heavily laden with ions from the heating coil which can cause electrostatic discharge damage to your components regardless of whether adequate temperatures can be reached. It would take forever.
