I'm wondering if you guys have an effective way. I usually just use pliers and my thumb nail to do what I can...

A heat gun set to low to accompany those pliers.
A working TV? How boring!Originally posted by PeteS in CA -

Exactly why do they poor that messy glue on some PSU components? Electronic noise? Vibration?

Re: Most effective way to get rid of all the glue in PSU's?
Vibrations and to hold them in place when they go on the line to be flow soldered
See how they move a bit when solder goes under:

And you have to keep in mind some of the manufacturers simply move the boards around on a big line with lots of employees simply taking a psu off the line, putting several parts on the board then putting the boards back on the line. A bunch of women take care of a part of the parts, so taking out, putting back, putting the board on the desk in front of them, all these can cause parts to pop out, if the leads are pre-cut.
For example see Gigabyte's factory tour, from about 5:30 in the video below:
http://www.youtube.com/watch?v=5vWrEmpRX_Q
The motherboards have more mass than a power supply board, so it vibrates less when going over the rollers and the liquid solder so the solder doesn't push the board around and won't make the parts get out of the holes as easily.
later edit: another gigabyte factory tour vid: http://www.youtube.com/watch?v=QdGW1xE6d_k where you can see in more detail the quality control process and stuff that's not in the previous video.
even later edit: oh, sometimes (rare cases) glue is also used as a mark for the human part placers to know to put parts there. same model but for asian market may not have an inductor, the european miodel may have it. It's easier to just put a drop of glue with an automatic machine than to re-train the women placing parts on board (or to do two separate batches)Last edited by mariushm; 11-08-2012, 10:01 AM.Comment

Very interesting videos, thanks
. That high-speed chip-placer is worth seeing

Apart from the mess, one problem I see with the glue is that some components can end literally jacketed in glue, and that's not good for cooling.Comment

Re: Most effective way to get rid of all the glue in PSU's?
Think that Enermax or who started using plastic forms some time ago to keep all components on their places. You can re-use the forms so you save money in long-term for the glue.
I personaly use pliers and also this:

Very handy thing for perforing mount-holes full of solder and many other things! Suggest getting one

Re: Most effective way to get rid of all the glue in PSU's?
I only have a paint stripping heat gun, but I will definitely try that next time.
I usually don't remove the glue, unless it's that tan/brown glue that goes conductive. I've noticed that some variants are more aggressive than others. For example, the type that Bestec uses usually not only becomes conductive but also corrodes component leads and PCB traces. The tan/brown glue in the PSUs of those HP DC5000 SFF computers I'm working on is even worse - besides corroding component leads, it also strips the paint off of capacitor sleeves.
If I was a power supply, I would despise coming in for repair in your "office".Originally posted by Behemot

I know many folks on this forum warn against conductive glue and suggest removing it immediately upon site. I'm here to vouch and say these people know what they are talking about. To be more accurate, the glue isn't intended to be and doesn't actually start out conductive. It gets conductive as it is heated by components that get hot. The glue starts out to be a light tan color but as it is exposed to heat, it gets darker and darker until it is a dark brown. I have found that it becomes conductive at the point that it reaches a light brown color on darker.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi Folks,
Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?
I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.
The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't... -

Please can someone tell me the chemical that can be apply to dissolve glue that used to hold the type C chip and SSD storage chip MacBook 2017 touchbar on the board.
Please i need a prescription of that chemical. i will be very glad if someone can help me out on that
