Is there a way for a hobbiest to use surface mount chips? I get these chips sent to me pretty regularly and I would love to be able to check out some of them, but I don't know what to do with them. For instance, I just got several Allegro a3967slb chips, which I could really use, but they are in the surface mount package (2 X 12 pins)
Forgive me if this is a stupid question, but I have never used anythinb but dip packaged chips.
you can buy various SMD to DIP adapters for use in breadboards, etc.
alternatively, if you etch your own circuit boards, you can use surface mount parts easily. You can check out the tutorial on my page if you are interested. (link in sig)
The trick with soldering SMD chips, is to hold them in place with a spot of glue, and using a fine tipped soldering iron and very fine solder, solder one corner first, then the diagonally opposite corner, then the rest of the pins. A magnifying glass may sometimes help.
I find it easier to put a small blob of solder on one of the pads on the board, then set the part in place while melting that blob. you can move the part around as you need by re-melting the blob, and when you get it where you want it you can do the rest of the pins. It saves you the hassle of having to have glue handy.
