Maybe it's not new, per se, but I think this is a great DIY solution for the more enterprising among us. Wouldn't have known if not for this vid in my feed.
Normally, this guy seems to know what he is doing. I think he just doesn't have much experience with surface-mount soldering. He has done many other videos about Macs which provide some pretty good advice and show proper techniques. He has also provided CRT warnings in many of those videos too. I found the Classic Mac Repair-athon series on this channel to be quite entertaining.I can't believe this guy has so much gear (EEVBlog DMM? Hot air?) and so little idea of how to use it.
Please explain how the hobbyists of us out here would obtain said squeegee and masks...I'd love that, but when soldering an SE/30 SCSI chip or the like, what other method can I use? I don't use anywhere near the amount that guy put on (too much bridging), but I have successfully done it by applying it across the pads with a toothpick.Oh no! That's an ugly, ugly way to use solder paste. It is normally applied by using a squeegee over a stencil that applies a controlled amount to each pad rather than blobbed out of the syringe bridging all the pads. I can't believe this guy has so much gear (EEVBlog DMM? Hot air?) and so little idea of how to use it.
edit: oh, and let's just crack open the Mac and work on it with no warning of the voltages around the CRT...

You need a different SIMM board for 16MB RAM chips for 64MB per bank if your machine can support it.
As someone who's learning, too, how did you remove the '020? I imagine you'd use hot air + lots of flux, but I'd be extremely worried about putting too much thermal stress on '020, I'd expect it to be the most fragile component.I’m no expert at all when it comes to soldering. I’m still learning. However when I watch that guy I feel like I’m a total pro.
I’ve removed and resoldered a 68020 CPU this way.
I use lots of good quality liquid flux and good solder braid. Several presses sucks up solder. No dragging, it will bend pins.As someone who's learning, too, how did you remove the '020?

THANK YOU for posting your SIMM design. I was going bonkers trying to find any contributions on that Vogons thread Adrian links to in his vid description…I made one that uses two 16M*4 chips. I used to source those chips from 128MB 72pin modules. One 72pin SIMM will give you enough chips to build 8 30pin SIMMs this way.
I think we can all agree there are plenty of better resources on soldering techniques, from users here, and from YouTube as well. I actually like that a lot of times his videos are the whole learning process. I'll admit, too, that while I know little about using paste, I could see it wasn't the correct way, but I waited to see if he'd correct himself. I think Adrian is just a normal everyman, and his only weakness is not saying up front w/re: specific skills—what to take and what not to take away—but that said, a few minutes in (it appears some commenters aren't watching the whole video) he flat out admits that his soldering isn't good technique and that he's learning. I don't see him as some malicious fountain of authority here, but he's someone with a lot of passion for their hobby; learning as they go. I know I can relate to that.
For decent camera work on SMD soldering/desoldering, I'm impressed with BranchusCreations channel. I don't watch every stream he does, but I have yet to see a Mac he hasn't fixed. He also has standalone tutorial and safety videos (which are much less than 2 hr stream lengths and easy to digest).
I also don't think him throwing out the rusted frame of a Classic II is a huge deal either. It was pretty rusted, and he did keep the case itself. Plus it's not like the Classic II is a particularly rare or sought after machine. He got 6 broken machines, and got 5 of them working. I'd say that's pretty good
