Gikfun DIY SMD SMT Welding Practice Soldering Skill Training Board Ek7028

Although I think this could be cheaper I think it gets the job done for learning new skills or brushing up on old ones. I bought this to brush up on some soldering after some time leaving university doing electronics. I thought it was a good quality board. Easy enough to do with some patience. I used 0.6mm diameter solder with a thin tip iron and a pair of helping hands. I say easy enough to do I have bought 3 of these since the first two I messed up. Put the polarity of some components the wrong way round and second one put the battery the wrong way round... Best to check to be sure to save yourself money. Instructions arent as easy to follow as they could be but all works one you finished.

Excellent for practicing soldering SMD 2-pole components. There are some 3-pole transistors and a couple of 8-14 pin ICs as well but only one of each, in one size, so not as much opportunity to practise those.

Useful, given different types of smd to solder. Not known if it actually constructs something. Instructions scant.

Nicely packed and PCB is good quality.

I got this to practice my soldering skills but found 75% of the components too small to be comfortable. If you want a challenge and can handle items less than 1mm in size, with appropiate tools then you will enjoy this kit. Sadly for me, I need something with regular sized capacitors and resistors.

I didn’t get any instructions with the kit just the board and parts so unsure where to start

While a bit expensive it will provide a good ammount of training. Not for beginners in electronics. This is SMT only, without an microscope is quite demanding, especially for the 0402. In the instructions said soldering iron and 0.6mm solder wire but for the 0603 and 0402 i did it with solder paste and hot air while keeping them in place with ceramic tweezers. The left and right side of the board have the components connected so a quick test on the multimeter should say if everything is well. The reverse of the board is usefull as template for sizes but also for straightening pins to the right pitch. Waiting for some BGA training from Gikfun, stencils and all.

Good fun build. The instructions are quite limited and assume a reasonable amount of electronics knowledge. The components are not clearly marked leading to a lot of detective work to work out what's what. The battery lead is not included. Also the instructions don't specify an input voltage (works fine with 9v).

This little board is laid out in a way that makes surface‑mount practice feel approachable, even if you’re just getting comfortable with smaller components. The instructions are easy to follow, the pads take solder well, and the mix of part sizes gives you a nice progression as you work through it. It’s a quick, low‑stress project that helps build confidence with SMD techniques and offers a satisfying result when finished. A solid choice for sharpening fine‑detail soldering skills

È buono ma potevano essere 5 stelle ma no si capisce gli smd da montare non sono spigati i valori e come montarli

I was very positively surprised by the quality of the included PCB. It's relatively thick, feels very solid, and has very good quality solder mask applied to it. The components themselves came in the usual stripes cut from reels. For most component types, few more were provided then needed, making things easier if one of the SMD components gets lost. The kit comes with a small printed manual, written in English language, which provides basic information on how to do surface-mount soldering, and has several illustrations explaining the steps needed to solder the components, how to identify the correct orientation of the included integrated circuits and diodes, and includes the schematic of the LED Blinker located in the middle of the PCB. The back side of the PCB has several rulers, in centimeters and in 1/10ths and 1/100ths of an inch, as well as examples of several popular PCB trace widths, and popular component footprints. As for the bad sides, there are few small points: The manual seems to be translated from Chinese. In general, grammar of the translation is very good, and manual is easy to understand, however few technical terms have been incorrectly translated: The manual always refers to the procedure as welding, instead of soldering, and it refers to the transistors as triodes. The direction of the SMD LEDs is not shown on the silkscreen, so it needs to be manually determined by following the traces on the board and using the included circuit schematic. Additionally, the measurement unit of 1/1000 of an inch is misspelled as mli instead of mil on the back side of the PCB. All in all, this is a great kit, but it does require some very basic knowledge of electronics.

I solder for over 50 years by now - now way less these days, but I felt for small repairs you need to work with SMD's, and so far I guess I was lucky. As the saying goes, practice makes perfect, and I can see my solder joints improve with every new component, and I can work out what works for me in placing and holding, etc. One issue with THIS kit I received, the 402 components are missing, annoying but I am not sure if I could freehand solder them anyway - but it would have been good to try. Had the kit for a few months before I spent time with it, so I did not complain to the vendor, who knows, they may have rectified it if I had. Update: when building the rest of the kit i found the 402 components in the other sealed bag.

Te dan un montón de cositas para soldar pero no te dicen que son ni están marcadas para que las coloques donde van
