Still better than Louis Rossman

But there's a playback speed selection in the YT player, ie, the gear symbol.

@@SidneyCritic doesn't allow over 2x, that's why i mentioned it

That is a good thought. However, how likely is it, that such a board would go trough another run of Pick&Place + Reflow just for the fuses (and maybe some other components)? I am asking out of curiosity. Is that really something that is done in motherboard manufaturing?

@@NebukadV I can think of one other apple device that had something similar in terms of solder used and that was the Iphone 10 that used lower melting point solder for its interposer sandwich board construction compared to the rest of the solder used on that board. I think that proves in principal that this can be done at manufacturing so I can imagine that fuses at manufacturing could be soldered with high melting point solder, but I would think it more likely that they would just attach fuses to bigger copper planes to soak excess heat.

It's using the same solder as the rest of the board; the issue is that with these boards there's a massive amount of thermal mass to counter/heat-up first. Even with a 1kW hot air station like the Quick 861DW or Atten it takes time to get that fuse off. Usually we pickle the ends with leaded solder to help it come off quicker. Macbook boards in general need quite a bit of heat to rework because of the extensive copper flood areas on multiple layers ( conversely, rework an iPhone like that and parts come off in seconds )

@@pldaniels Yeah I thought that was the more likely explanation.

One of these kits: www.ebay.co.uk/itm/154812401897 I've modified mine with a lipo batt and USB charging, but other than that it's a cheap kit one. There are lots of variations of the "Transistor Tester", but I'm not sure if they all have the same features. You can check capacitance with most multimeters, but these transistor testers are very good for a poor man's ESR test as well.

FlexBV, available from pldaniels.com/flexbv/ There is a free alternative called OpenBV which does basic stuff, but lacks the schematic view and built-in measurements plus more than Flex has.

Yea, FlexBV can open a lot of stuff - just that board views for other laptops are often very hard to find. I always get it out for MacBooks though, as they're very well documented, so the board views are easy to find.

Reinforcing what Graham has just said, yes, FlexBV works with most boardview formats and is entirely generic, not being locked to any specific brand or series; in fact, you can create your own boardview files from most PCB/schematic design suites. It is worth noting though that PDFs don't contain the information required to be boardviews ( ie, the iPhone schematics are in PDF of course and they show a part placement diagram in the first two pages, but it's not something that can be used as an actual boardview ). Essentially boardview files are a long list of 3 main bits of data; pin { name, position, side, part, net }, part { name, position, pins[] }, board outline { position[] }

That's definitely something to consider, I shall ponder!

Appreciate the offer, but I don't think there's much to tell on these - I've always found USB3 add-in cards to be unreliable. Haven't tried a Type-C one, but it sounds like they're the same as always!

@@Adamant_IT Cheers for the response, no worries I'll have re-try one day when upgrade.

You're sort-of right. Vcore doesn't short when turned off, it's just always _low resistance_ , to the tune of 3-4Ohms. However, that low resistance will be _after_ the vcore mosfets, and in this video we're working on input capacitors _before_ the mosfets.

Silicone like the CPU and chipset will always appear to be shorted due to their low internal resistance. It's a red herring. Use resistance mode, not beep mode, on your multimeter, and you should find they have a few ohms of resistance.

@@Adamant_IT Thank you very much maister !

Oh the fuse was blown all along

I mean, I've not done as many of these as a great deal, but I've seen a fair few shorted PPBUS_G3Hs and yea, it seems like the rail will droop to zero before the fuse blows most of the time. But hey, now I've seen one, I'll probably see many!

Actually I did, and there was no smell! I should've left that bit in though, yea. It's in the screen cut during the moment where I'm looking at the board.
