Re: [electronics101] Test Probes Wash 0402 LED strips

There are also tweezer test probes that have tiny metal tips connected to a pair of test leads.

They are convenient for measuring loose SMT parts on the work bench.

There are also tiny “pen-style” capacitance / resistance DMM with built in tweezers.

I use a stereo microscope when working on tiny parts.  It works extremely well!  My eyes are old too.

For probing 0402 parts, personally I think a small fixture with both probes glued to it, would not be a bad idea.  They should be the right spacing for 0402 sized components.  I have enough trouble getting one probe in the right place (ancient eyes), so getting two of them to both "stay put" where I want them can be a near impossibility.  Having to hold only one fixture with the right probe spacing, helps with that.

 

I was a little surprised that you could solder to sewing needles, but honestly I never tried it.  It might depend on the brand of needle, and the heat of your iron, especially if the needle is clamped in a vise for soldering.
