Easy-Cheap-DIY-SMD mounting guide.

A little something I threw together.


NOTE: The cheap Radio Scrap Iron is as a second to be used with your main 1 for heating the SMD component from both sides simultaneously. This is ONLY to aid in removing many components. It is not used for assembly.

This is where you use the tweezers.

Sometime ago I say a description of a hot air pencil made from Radio shack parts. Have you any experience/familiarity with this device?

THanx

for a novice it helps.

Look for the 25$ heated soldier pump.

Remove the pump. Add a fish tank air pump on a separate footswitch & voila. I run mine at 240v with a little step up transformer, the extra heat removes the need for a heated soldier table.

For a heated SMD soldier table, get a 10$ mini 1 stove top cooker & a 1 rectangular near all flat frying pan.

These are other extra cheap DIY methods.

This is exactly for whom the document was written. Novice engineers / experimenters who never worked with SMD before may not realize some of these simple steps which make good flat SMD work with a normal iron possible. Or, that the purchases items on page 1 would last for a few thousand 2-3 pin components. Over 500 8 pin, or 14 pin SMD ICs.

I've never used multiple irons to remove a two "lead" device. I always use the method of building up a little extra solder on one side, then quickly switching the iron to the opposite side and "pushing" the component off the pad. Works like a charm. I've never ruined a component this way, even ceramic caps.

This is usually what I do too, but if you have 10 or more to change, having that 5$ second iron & using the 2 like a heated tweeser to pick off all the resistors is really less messy & the removed resistors are really clean for future use.
