I have done recaps on motherboards before and had no issues. A few years ago I "upgraded" my soldering equipment. I had an old Radio Shack iron. Upgraded to the digital station and a new hand held iron. Now I have nothing but issues. No matter what I try, I cant seem to get the caps to budge on some boards. Last one was a dell motherboard. Caps refused to budge, even with a large solder gun. Wondering what solder station would be best for this? Only want to spend around $100. Looking at a Trakpower TK950 or a Hakko Digital FX888D. I am hoping this will help to solve my issues. Never had an issue until using these newer irons.

Re: Motherboard recap issue
Depending on when you are talking about it may not be just that irons are not as good, it could be some years ago you were working on boards with leaded solder whereas if you are now working on newer boards they will have unleaded solder which has a higher melting point. Also at some point I believe they started making boards a little bit thinner then had to add metallic lines to make them stronger.
This leeches away the heat. Now when using the iron I work in a warm room and pre heat the board with a hairdryer.
Its great in winter

Re: Motherboard recap issue
I have used an FX-888D to recap motherboards. It works fine with the right tip, e.g. T18-D32 which is a 3.2mm chisel tip. A smaller tip (such as the T18-D16 1.6mm chisel tip that comes with it) may have a harder time moving enough heat. Of course, you also need to keep the tip clean enough and tinned properly to move any heat at all.Last edited by Uniballer; 01-11-2014, 07:47 PM.Comment

Re: Motherboard recap issue
I am using the radio shack digital soldering station. Properly cleaned and tinned the tip. Just seems to lack enough heating power even turned up all the way. My old radio shack iron was much better. Will more than likely go with the FX-888d. May need to start pre-heating the board. I do have a heat gun.Comment

Re: Motherboard recap issue
the guy who had time to teach me a few things about electronics had one, before i came to him and i was around him about 4-5 years.
i can tell you this. he always kept it on. that was bad because he bought alot of tips.
just before i came he bought a new iron cuz the old one was going on for a couple of years.
I got a crap 60W to main wall iron about 15-25 GBP and a gordak station( i can put a small tip on it)
but at the end of this month i will get that ws 51 weller; believe me there is now iron can compare to that weller.
I can say only thing when you get used to a iron that is magnetize and you will never use a Wick or a pump that`s precious.
Good luck!Just cook it! It's already broken.Comment

Re: Motherboard recap issue
I agree.
For those of you who think Weller is nice, wait until you try JBC. I had the chance to use one of their stations and that thing really is the Rolls Royce of soldering stations. Not to mention it never struggled to heat anything. You could probably melt all of the ice in the South pole with it if you tried.Comment

Re: Motherboard recap issue
Thanks for all the advice. I think the fx-888d looks like a good fit. I know there are better stations out there, but this is a side job, so around $100 is good. The radio shack iron I used was not 25watt. It is a 60 watt. I am a firm believer that things aren't made a well as they should be. It's a lot harder to find well made stuff at a decent price. It will be nice to do a repair and not have to fight with my tools.Comment

Re: Motherboard recap issue
With the ever little soldering I do now, I fully expect the FX888 to last my lifetime so spending the extra $30 was a no brainer for me.
Now if the FX888 was in the $500 category, I would have bought a $60 Hakko ebay soldering station knockoff.
I suggest getting a 3.2mm chisel tip for desoldering.
PS. Dave Jones' teardown of the FX888 also convinced me to spend a few $$$ more so my house doesn't burn down to cheap incorrectly wired knockoffs.--- begin sig file ---

Re: Motherboard recap issue
I bought a RS Pro-Line 70W station on sale for about $50 and it is no good for recapping motherboards even using a Hakko 900 type 2mm chisel tip (which is a close fit but the cylinder of the tip that goes over the element is 2mm longer on the inside length). It is rated at 70W but that energy isn't making it to the element or tip and it certainly does not achieve it's max temp of 480c +/- 5%. It is absolutely useless for laminated motherboards.
I used a Mastech MS8264 meter (accurate within 1% up to 400c, 2% up to 1000c) to measure tip temp using the conical tip supplied with the unit. My readings were:
Setting/Actual temp
480c/388c
400c/328c
300c/244c
200c/137c
Using the Hakko 2mm chisel tip it got up to 420c when set at 480c (max) and 155c set at 200c (min). Not even close to the rated +/-5% tolerance. I did open up the controller and could not find any calibration adjustment. Out of the box it is a $50 disappointment for sure. I'm shopping for a better unit and chock this one up to experience.Comment

by momakaHere’s another motherboard that needed a full recap: an ASUS P5GC-MX.
This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.
So here is what the motherboard looked like with its original caps:

by DocusHi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

by MakNCheeseHi everyone,
I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.
Symptoms:- Severe lag across the system, including BIOS navigation.
- Slow boot times and unresponsive performance in Windows.
- Battery charges very slowly (e.g., ~5% in 2–3 hours).
- No error messages or BSODs, just extreme sluggishness.
What I've Tried:- Replaced

by fixme2024Hello everyone, I have an HP DV6 DAOLX6MB6F2 REV: F motherboard. The issue I'm facing is that sometimes the motherboard doesn't turn on. I've checked the voltages for the power on button panel, and they seem to be okay. Right now, it's working perfectly fine, so I can't pinpoint the exact problem. I have the HP DV6-DV7 Quanta LX6_7 (Liverpool) DAOLX6MB6F2 Rev 1A.pdf schematics, a multimeter, and a 5A power supply. If anyone could guide me on where to start checking first, I would greatly appreciate it. This is my first experience with this. Thank you.

by wagollaHP laptop with the LA-G07FP motherboard has encountered persistent issues with powering on and charging. Here are the details:
- The laptop does not power on or charge consistently.
- When I remove and then reinsert the battery, the laptop will turn on when connected to the power adapter, and the battery charges normally.
- However, after approximately 1-2 days, the issue reoccurs, and the laptop will not power on or charge until I repeat the battery removal process.
- I have already updated the drivers and BIOS via the HP support website, but the problem persists.
