Only if you're using a process involving some sort of reflow oven. Some DIY projects use toaster ovens for this. I tried it a few times but wasn't happy with the results. > and a mask (to prevent the paste from going all over the board). The mask is the "clean" way to do it, but some people even just put little drops of solder paste on the pads before their DIY board goes into the oven. > How does this method work? For most things, I just apply flux, place the component, then solder it with an iron: - for things like resistors, I put a tiny bit of solder on the tip of the iron, hold the component down with tweezers, then dab the solder on one the terminals. - for things like QFN, I do pretty much the same but then do one or more rounds of applying flux and melting the solder again. This is to make sure I really solder all the contacts. There were two exceptions: the crystal and the QFN center pad that requires a ground connection. For these I used solder paste. Since my hot air pump broke and I don't like hot air too much anyway, I just used the soldering iron to melt the solder paste. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
