TQFP Replacement

[wasssup1990]

Thanks for the video. I'll need to make a very compact circuit board for a remote control that I'm making. It's getting clearer that I should now use surface mount devices. Wish me luck!

Do you have any recomendations on how I should go about making an SMD PCB?

does your iron has a thin tip? I mean, do your replace the original for a thinner tip? Because I have to solder a tqfp 100 IC so I'm gathering some information about what iron should I buy...

Thanks and good job!

mine doeshave a small top but the best way to tackle a tqfp 100 would be to put a lot of flux on the board and then use a very wide tip to drag a lot of solder over all the pins on one side at a time.

The flux should cause the solder to ball/bead on each pin and not to bridge or short between pins.

it might be helpful to solder 1 pin on each side .

first with a small tip and then drag the large amounts of solder over the rest of the pins

how did you remove the old chip?

Hot air?

See my other video. Hot air would have been a brilliant way to go unfortunately I made a great example of how not to tackle SMD removal.

thx

Damn, I've always had trouble with surface mounting on PCB's, but yoiu make it look so easy. And nice removal of the solder bridge! ^_^

so what.did it work???

good job
