Re: SMD and hams
That is really sound advice, Ruud.
I know that regular resistors and capacitors have an uncanny knack of hiding themselves in pile carpets, but SMD must have other issues.
At least regular components often stick to magnets, so a magnet under the ESD-mat can keep control of some of them.
Thanks for the tip. Very best regards from HARRY - SM0VPO

Re: SMD and hams
A good (and serious) advice: don't sneeze when you are working with SMD components!
It happened to me more than once...

Hello Ivan,
I have been thinking about using SMD components, but my eyes are not as good as they used to be.
I though about doing exactly as you suggest - soldering leads to the chips and using them as regular components. About a month ago I bought a head-mounted stereo microscope so I can work on small stuff once more. They are like the magnifyiers you see surgeons using in TV movies. It has inter-changeable lenses. I am expecting delivery any day now.
I saw that several companies offer "SMD-Kits" where you can solder an SMD IC on the header-board and fit legs so that they can plug into a normal IC socket. As you pointed out, 2.5mm component spacing will still accept an SMD component. But as always it is just to try and see what you can do.

Hi,

There is no need to make dedicated PCBs for SMD chips. Small reduction PCBs for one SMD case can be obtained for cheap e.g. here. You solder the chip on and solder pins or wires into the holes around. You can then use it like a common DIP. The stray capacitances may increase a bit.
I recommend a hot air pen like this for soldering SMDs. It is smaller and cheaper than a reflow device etc. A magnifier glass, a syringe of soldering tin paste and a pair of tweezers is all other equipment needed.
