I've started down the path of working with Surface Mount Devices.
[Look, these newer radios are using them throughout! If I want to
modify my TS-2000, I have now gained the equipment and skills to do so!]
Obtained a USB 20X to 800X Microscope.
I also obtained a Hot Air Rework Station.
I've been looking at the Microwave Arena.
Quite frankly, the "better" known folks do NOT use ROHS solder either!
Dr. Gerald N. Johnson, K0CQ, highly recommends 60/40 solder due to
better plasticity time to work with. He has a presentation,
In this is the differences in the ROHS vs. Sn/Pb solders.
I've been working with it for a few months now.
I use 0.015" Multicore SN60/40 solder.
It can be a bit tedious, but the hands are still steady enough.
Transparency blanks for printers make good stencils for masking the
components locations to prep the boards.
Then you need a "good" metal framed magnifier lamp. Not the plastic
junk ones from Harbor Freight. Although you can use one before you
decide to get serious.
So far so good!
