Re: Preemptively Recap Motherboard?
looks familiar!

this is the one sold by weller:

and this is a variant with better grip:

Re: Preemptively Recap Motherboard?
The patents on the original Edsyn Soldapullt DS017 expired quite a while ago. So the new clones might be every bit as good. But I don't like the designs that continue half the tube to provide plunger protection. I have to keep shifting my grip on those to be able to work the plunger with my thumb. With the Soldapullt DS017 configuration you keep your thumb on the trigger button while you flip the pump around and press it against the bench (or your chest) to get ready for the next joint.Comment

Re: Preemptively Recap Motherboard?
My impressions of a new GY-059 desoldering pump:
The GY-059 looks very similar to an Edsyn Soldapullt DS017. I would say that it was intended to look identical, but there are a few small but noticeable differences if you are looking for them. The plastic is a darker blue, and some parts have slightly different corners, or rounding. Barrel parts will not quite interchange with those from an Edsyn DS017; the locking tabs are a different size. I could not push out the tip from the GY-059 without removing the end cap, despite the pictorial instructions indicating this method (the cocking piston appears to be a little too short). The tip appears to interchange with an Edsyn SRT12, but it is not built exactly the same. The lettering "NO SOLVENTS OR HEAT" and "COVERED BY U.S. AND FOREIGN PATENTS & PENDING APPLICATIONS" on the side of the barrel are in a slightly different font.
Suction appears to be excellent, both by the thumb test and in actual use. The release is smooth enough that the tip does not hop around. The tip did not melt or deform when I contacted it for a short time with a Hakko FX-888D with a 3.2mm chisel tip set to 350 C. I can't say anything about long-term reliability, but while new I found the operation of this tool to be essentially indistinguishable from an original Edsyn Soldapullt DS017.Last edited by Uniballer; 08-19-2014, 07:09 PM.Comment

Re: Preemptively Recap Motherboard?
It seems that the rod that cleans out the tip might be a little smaller on the GY-059, and the tip I.D. is definitely a little bigger. In any case there is a bigger gap between the inside of the tip and the cleanout rod. I haven't seen any ill effects from this yet.Last edited by Uniballer; 08-20-2014, 04:54 AM.Comment

Re: Preemptively Recap Motherboard?
Excellent, well-worded review Uniballer. I've been considering purchasing one of the knock-offs for some time now. By the way, the tips are made of teflon, and I've seen Chinese replacements available inexpensively.Comment

Re: Preemptively Recap Motherboard?
teflon or not, they will melt.
put some hellerman on the end.Comment

Re: Preemptively Recap Motherboard?
Teflon has a maximum temperature of 300C... The tubing you're recommending has a maximum temperature of 95C according to the datasheet. How exactly will it prevent the tip from melting?Comment

Re: Preemptively Recap Motherboard?
the hellerman sleeve is used slightly overhanging the end of the tip by about 3-4mm
it creates a seal to make the pump work over 100% better than before.
yes, hellerman sleeve will burn - very slowly.
first it will harden slightly, then go brown, then crack.
it takes hundreds of desoldering uses for that to happen.
and you get the sleeves in a bag of 100 or more and cut them in 2.
so it's a reasonable "consumable item" to use.Comment

Here’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:

Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Hi 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.

Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.
Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.
Fans are spinning. Blindly could install windows11 and got the device manager... -
Hi, I have some 32 bits computer motherboards that need repair, as they fail to
power on.
Here are some examples :
(N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
switching supply area).
(N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
than 6.3 V.)
1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
I replaced capacitors with aluminum-polymer.
