Re: Opinions on surface mounting

2002-05-08 by osthelder

Hello all!

Installing surface mount devices of the type Paul is suggesting is 
really no more difficult than many of the mods we make to existing 
pcb's.  With the pads of the pcb pre-tinned, one simply aligns the IC 
and holds it in place with gentle pressure from a tool like a tweezer 
or small screwdriver.  This just keeps your fat fingers away from the 
soldering iron.  Heat one corner leg of the device until the solder 
melts-just a tack joint.  Then do the leg on the opposite corner.  
Lastly, heat each joint while maintaining a light downward pressure 
and you're done.

A simple tool can be made to apply downward force while leaving both 
hands free.  I read about it some months ago in QST (the radio 
amateur's magazine) and I will post the article if I find it and 
there's interest.  It resembles a tonearm for a record player (those 
too young to remember records should do a search on the 'net!)and 
should be adaptable to any work station.

Paul, if you design it-they will come...
