Re: Transmitter Mods

Last night I gave a presentation to our club about using SMD parts in projects. One of the things I discussed was the use of a decent solder station, like this one:

which sells for $62 (eBay 381253195679). I have one and it works well. The nice thing about a hot air gun is that the kind of thing you're talking about is pretty easy since both ends of the SMD are heated at the same time. (See the hot air nozzle choices.) This one even has a small variable PS with it which sometimes is handy when breadboarding. The microscope I want to get is different than what I have. This is the one I want to get: eBay #123142757131 for about $60.

Because my club has a fairly active knot of members who enjoy building "stuff", I'm going to propose that the club purchase both items as part of our Tool Chest, which our members can sign out.

The teepee was the hardest part for me.  My first thought was to heat one side and try to lift it, but that didn't work as the other side still held tough.  Next I wicked both ends and then tried the same thing again and got some movement.  Finally, I just applied pressure to the side and heat and slid it off the pad completely and started the tee pee fresh.  My inductor is a squat little thing so I soldered it down as a tower on one pad and then re-applied the resistor as a bridge.

My biggest concern was either a) destroying the resistor with heat, or b) flicking it off and sending it into the ether while trying to desolder.  I have a SMD resistor sampler pack and I think I read it as being a 102 (1k ohm), so I had that as a fallback and maybe made me a bit braver on my application of heat and force.

Hi Rob

Doing these mods this evening.  Much appreciated Howard's parts.

For the tee pee - let me know how you did it.

I am going to gently put the solder iron on right side and try to lift it as soon as solder start to give.  Any suggestions will be appreciated.
