Soldering Practice Kit,3 Kits SMD SMT Weldering Skills Training Board(Soldering-All)

The media could not be loaded. I mostly soldered all of the boards by hand, which was great practice/learning. I did use solder paste and hot air for the 0402s - they are simply so small to handle. I did do a couple by hand and it is possible, but I also wanted to practice some with the solder pasted - worked well.Some tips, mostly on the large board:** Tape the qfps down on two sides (one piece of tape). I just cut some thin masking tape. Tape it down, solder the two sides, remove the tape, solder the rest.** The electrolytic capacitors - the leads are very small and they don't hardly extend on the solder pads - just barely. I tinned the pads first, then put down the caps, but it was iffy. When cleaning the board I popped one off and replaced it with a regular cap instead, with real leads.** The board requires 9V AC power to test and see if it works. I had a doorbell transformer set to 10V AC that I used, and that worked. You will need to locate an adapter, AC to AC to test it.** Use some extra flux if soldering by hand. I used flux-core leaded solder and also extra flux - it worked well.** Use a fine-tip solder iron, some fine tweezers, and good reading glasses. I had my iron set at 625F.** I used the tweezers to hold the component in place, and with a dab of solder on my tip, I tacked the component down on one side to hold it, then finished soldering - worked well.These are some challenging and satisfying boards to do. Whatever your skill level, after you finish these boards correctly, you will definitely have moved up a couple of notches in your soldering skills. I've done some through-hole projects and a couple of small smds prior to these. I saw the big board and wanted to tackle that - I'm glad I did. I would not suggest this project to a beginner. Get some easier through-hole projects first, a couple of easier smds, and then maybe try this - there are a lot of things that can go wrong and if one part is not done right, the board will not work... Enjoy and good luck.

If this was something that you needed to function, the lack of documentation is a major problem.The quality of the PCB and parts isn't very high, but good enough to practice with. I bought this for an intern at work. She has to constantly ask where the different parts go. More documentation would be gread.

instructions ok...sometimes things are missing. I have ordered these a couple of times when I was just getting started and it has improved my skill in smd work. recommend getting a magnifier or scope before you try to do these.

Exactly what I was looking for. Quality seems great.

The kit was short an item and the seller contacted me and quickly resolved the problem to my liking. I would buy from again. He is a great seller

These work as you would expect. Directions are a little hard to follow. I installed the LEDs backwards and had to buy extra LEDs to finish the kits.

I've been doing all my soldering with a bulky pencil type iron I bought at Radio Shack 30 years ago. I treated myself to a hot air rework station during last year's Amazon Day sale. I'd never done any SMD work with hot air, so I bought these to gain some skills. It took me a hot minute (pun intended) to figure out the Engrish instructions that came with the kits. Once I got it figured out, though, it was a lot of fun assembling the boards. They were even thoughtful enough to include extras of the very small components. I definitely fat fingered some of the packages and sent tiny parts into orbit, never to be seen again. Everything lit up beautifully when I finished and applied power. I'm thinking about adding the smallest as a project for the engineering classes I teach at the local university. I was already a skilled at soldering, but I was better by the time I finished.

There are many parts but only a few actually comprise the functional circuit. The describe the functional and solder practice only clearly. The lighted circuit works delightfully, a reward for using sparing amounts of solder paste! The red board is a good start. Then the green. Blue last since it is way more involved.Did the second board (green pcb) same circuit but corner LED's are blue. Good schematic but resistance values do not match the parts! Where it says 330 Ω use 1kΩ, just like the red board. Where it says 2MΩ, use 10 meg, just like the red board. The red board had little +'s for LED and the 1N4148 diodes. The green board did not. No matter, the plus end of the diodes all were connected to a resistor.
