I've just completed my first reflow board and I'm very happy with the results. It's just a small board with 3 TSSOPS and half a dozen 0603 caps. I used a hotplate with a piece of 3/8" aluminum plate to spread the heat. All went well but I did end up with three tiny bridges. Two on one chip and one on another. I used a 4mil steel stencil from OSH Stencils.
So what's the best way to remedy these? Exacto knife? Hot air rework? The knife I have, rework tools I don't (yet).
And what's the best way to prevent bridges in future projects? Placing the components isn't easy for me and I wonder if my hands aren't steady enough. Could I be smearing the paste trying to get the chips in place? The next project uses QFN parts and I'm worried that bridging will be more difficult to correct.
Any advice, tips or tricks would be greatly appreciated!
