They sell those as coin microscopes. I use a LAN-based CCTV camera. I can place it far enough from the pcb (the software has a nice zoom function) to be able to do SMT soldering with it... -- Paul

Here's my $20 recommendation and some sample photos made with it: http://ae5x.blogspot.com/2018/11/microphotography-for-20.html John AE5X

How many sets of the Sierra components are available? How do I buy a set? Can I use PayPal? Bob Macklin Seattle, Wa

Besides agreeing with others on technique, I use bamboo skewers (for cooking) to hold the parts down, move them around. 72 - Ron - AG1P

Mark, What is the brand and model number of your microscope? One of these days I am going to get one. Al, N8WQ

One thing to be careful with using solder paste is it tends to create very small solder balls that you can't see without a microscope. Even a good cleaning in alcohol and toothbrush won't remove them.

I've done that and it does work well. However, if you're really going to work with SMD parts, nothing beats solder paste and a hot air gun. I use a dental pick to put the paste on, drop the SMD in

Hi Joe, Is that the same hole where the socks go when they are missing from the laundry? 73, Bill KU8H -- bark less - wag more

A few months back our local club had a speaker who talked about SMD soldering and he had some excellent suggestions (he is a retired EE who did PCB design for a telecom's company). The most useful

If I may, I have a monthly live-stream building projects. Vast majority of them are SMD. Here's the N2PK VNA: https://youtu.be/V7cjk41LTEI Here's QRPGuys Digital Field Strength Meter:

How about 0603 parts? I use the tweezer technique but the problem is seeing. I recently got a $22 digital microscope from eBay and it works great.

Folks, Thanks for the research work on the XTAL sources. I am not sure how many have seen the prices for the boards offered by Dirk, et al, but I received a response (below) from Dirk, DH4YM, that may

Just for the record, I do not use tape or tweezers or any other tool for that mater. I use my left index finger to hold down the part...1206 size or larger Tack solder the part on one side/corner...

Agreed. Also, if you use the Tweezer Approach to hold an SMD, know that they can become hypersonic Tiddlywinks and end up in Near-Earth orbit, also never to be seen again. Jack, W8TEE

Wolfgang, I keep being bothered by the fact that most, if not all, of the waveforms you show in your photos look correct, but just not the right amplitude.? Is it possible that your scope probe is

I agree that SMD parts are easier to solder than through-hole parts but the main problem I have is finding the SMD parts and getting them on the board!! (grin). And don’t ever drop an SMD part…it
