Re: Aluminum caps
For SMD caps, apply flux to each pad. Mix a small amount of 63/37 solder in with the existing solder on the pads. Do it quickly and the flux will leave smooth mounds. With the lead solder mixed in the melting point will be much lower and your soldering iron will be able to heat each end as you push the cap down without burning the cap up. Clean the flux with swabs and alcohol or brake cleaner. The cap won't attach as strong as the original solder work but this simple technique works for me.
If you have two soldering irons and two people, one person heats the two sides and the other person pushes the cap in. That will result in very strong solder joints and some burned fingers.Last edited by severach; 02-19-2011, 02:03 AM. -
Re: Aluminum caps
I would try what I saw on a Youtube video...
Apply flux then tack one side of the capacitor with a tinned iron tip, then solder the other side by laying solder 75% the way across the pad and bringing the iron tip in, then back out after the solder has flowed (chisel tip works best)
Repeat with the other joint, clean off flux.. here's the video anyway: http://www.youtube.com/watch?v=_IqJdJEMUOE"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

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... -
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

The PCB motor for 1987 Technics SLP-120 CD player has slow spin-up issues. Similar to what another tech in the below video reported.

I replaced the three bi-polar 47uF electros but that made no difference. The orig three bi-polar 47uF electros tested okay on my ESR M-tester.
I have not tested/replaced those alum. SMD electro PCB caps.
Are Al smd caps are more prone to failure (or degradation) than regular thru-hole electros?

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
