surface mounting DIP/DIL package?

[dalmation]

Does anyone have a tried and tested technique for surface mounting DIP/DIL packaged IC's?

I was gonna bend the pins out or under and give it a try. I might even bend then over and mount the chip upside down for one particular circuit where the pinout would be much better 'mirror image'. I know it sounds daft, but I have my reasons.

Anyone had any experience of this madness?

Thanks in advance.

I have used DIP ic's with legs bent at right angles, works fine.
You can crop the pins/legs to shorten them if space is tight.

Never used the method for upside/down mounting.

CAUTION: the legs will break off, if repeatedly bent to and fro.

I'll experiment tonight (with the cheapest IC's I can find).

I'll also try converting some of my sockets into SMD.

The upside down thing might be a bit ambitious, but I'm gonna try it anyway.

I'll post pictures if I get good results.

I've bent the legs under the DIP package with success. You need to trim the leads back a bit so they don't touch any traces running under the IC.

It worked good for me.

I had a wee go there.

Bent the bottom half of the legs outwards (90 degrees), then trimmed them back with snips (using a credit card as a spacer to leave a 1mm 'foot'.

Looks just like a SOIC chip now. It makes the chip footprint quite wide, so I'll try bending under the chip as well.
