YIHUA 929D-V Electric Desoldering Soldering Iron Solder Sucker Desoldering Pump with Shorter Charging Handle and Desoldering Nozzles 1.0mm 1.2mm for Through-Hole Desoldering

Satisfied with this solder sucker. Heat level is sufficient, heats up quickly, not too large so it is easy to hold, pump vacuum seems fine, effectively removes solder, nozzles unscrew easily.

My step-son's Switch controller needed a new joystick. As an amateur electronics kit builder, I figured, "no problem", but there were 14 pins needing to be un-soldered. I've used a solder-sucker before, but this looked like it might be too much work for what I had. This tool served as both the soldering iron and sucker at the same time, so no switching back-and-forth. For this reason, it would be worth the price if I expected to use it often. For me, it will probably get used only very occasionally, but it's nice to keep with the other DIY electronic tools just in case. It was easy to clean out the bits, and at came with three extra tips, though I haven't needed any others than the one installed. It had enough power to melt the solder on both sides of the PCB, and sucked it right through the hole, needing to be re-applied on only a few of the 14 pins. It's handle was very ergonomic, fitting my hand well, making it easy to de-solder and trigger the suction with one hand. The only problem that took getting used to was holding the tip against the PCB. The spring action of the piston tended to make the tip bounce off of the board, preventing the suction from working. Some careful pressure solved that problem with a few tries.

The good: Very easy to use, heats and liquifies existing joints quickly, metal tip doesn't burn or melt like the teflon-tipped suckers, easy to clean, does not clog easily. At $40, it is priced in between expensive desoldering guns (which cost $200+) and the cheap spring-loaded "solder suckers" that can be had for $10, and it's performance and quality are appropriate for that middle price. --- The not-so-good: While this thing works much better than the unheated vacuum plunger style solder sucker, it does not have the suction I thought it would. On 2-lead through-hole components, it can usually pull all the solder out in one shot. But sometimes you need press the plunger and repeat the process. This is fully through-plated holes, I'm talking about (which everything I work on has). It just cannot draw all the solder out of the hole so that both sides of the plated hole are free of solder and the component lead is no longer stuck. On heavier 3-lead components, like a TO-220 power transistor, I had to sometimes to 5 or more cycles of pressing it firmly over the lead, letting it melt the solder, push the trigger, let it suck SOME of the solder out. Holding it over the lead for a longer time helps, because it more thoroughtly liquifies the solder all the way through the hole. But you need to keep a wet sponge or other heat sink on the compon ent if you do this or the heat will destroy it. I had no trouble getting the hole in the top to fit over all the leads I tested it on, and I did this on everything from little 1/8w through-hole resistors up to larger 3-lead power transistors, 4 amp diodes, and medium sized (2000 uF or so) electrolytic capacitors. It works much better on 2-lead components, because as soon as the solder softens, the lead tends to move toward the center of the hole, and thus when the solder is drawn out, even if it isn't perfect, it isn't stuck to the lead. On a 3-lead device, there are always 2 leads still soldered when you are opening the first hole, so nothing moves, the lead stays against the side of the hole, and any tiny dot of solder will keep it stuck there. Like I said, overall, much better than a plain unheated sucker tool, but not the powerful vacuum I was hoping for, so 4 stars is all it gets.

I'm in the process of deconstructing an old radio for restoration. This solder sucker works perfectly on printed circuit boards and leave the circuit board traces intact. It also works for point to point wiring. Cleaning it is easy and it is a good value...it may just save having to repair a circuit board from a bad desoldering attempt. The size is small enough to get into fairly tight spaces. The spring mechanism is a little stout to use but the amount of suction provided is really good. There is no temperature control, so you do have to be careful on some parts like diodes, transistors and IC's

Great desoldering tool! I used it to repair joysticks on a PS5 edge controller. Worked perfectly!

The Yihua 9290-V Electric Desoldering Iron offers a significant improvement over copper braid (wick) and manual, non heated solder suction methods. As an experienced electronic bench technician, I have often had problems removing all of the solder from the legs of transistors, capacitors, resistors and other devices mounted via through-holes in circuit boards. I have found that there is often no substitute for a heated solder sucking device such at the Yihua unit. Heat output is very good, even for melting and removing larger solder blobs. If removing solder from very fine or extremely heat sensitive devices, there are outboard, plug-in adjustable power reduction devices, similar to light dimmers, that can be used to reduce the tip temperature of the desoldering unit as needed. Also, having a removable, replaceable tip is a definite advantage. The solder sucker portion is easily removed from the heating section of the iron and emptied. Invest in some silicon oil to keep the O-ring and inside barrel of the solder sucker lubricated. This will optimize the sucking action of the unit by reducing internal friction, and it will greatly extend its useful life. As other reviews have mentioned, the Yihua Desoldering Iron puts out a notable quantity of smoke when it is first powered up. Place it outside in non-flammable surroundings when first powering it up for ten minutes or so or until the unit no longer smokes (and don't breathe in the smoke, just to be safe). Once this is done, the unit should no longer smoke when you plug it in, later. The Yihua 9290-V Desoldering Iron has been working well for me. Recommended.

I use this when needed, works well.

Hasta el momento a sido de gran ayuda. Facilidad al desoldar componentes electrónicos.. Muy práctico funciona bien. Ahorra tiempo....👍
