These guys are a list of Who's Who of kit builders and designers. I just had to have the AD8307 RF signal probe. I hope there are new kits in the pipe line.
I received my kit two days ago.
This morning I completed installation of the surface mount devices after reading Steve Ratzlaff's review in message #11208.
The pads have some mass so the soldering iron needs to provide some heat. I used a larger than normal SMD tip on my Hakko 936. I also applied flux from a pen before soldering.
The LM358 soldered very nicely. But the AD8307 was a different story. The IC pins were reluctant to take solder. When the flux pen didn't work I added some liquid flux from a bottle with a brush. I finally got contract when I resorted to solder with 2% silver. My normal solder is 63-37 tin-lead.
The 1206 components soldered fine.
I'm building my kit, stock. I'll see how it works before considering Steve's changes.
