The way I usually do surface mount is, I put a dab of solder on one pad, then slide the part into position with the iron still on the solder blob. When it's in position, I lift up the soldering iron, while keeping the part steady until the solder cools. That way the part is fixed in place, making it easier to work on the rest of the pads. Then I solder the rest of the pads in the conventional method (touch tip to pad and component, bring in the solder.) For parts with lots of closely spaced legs (like ICs, USB ports/other types of connectors, etc.) I do the same thing (put a dab of solder on one of the corner pins, slide the part in position, wait for the solder to cool.) Then I hit it with a lot of flux (i use the paste kind rather than the liquid, I think it adheres better.) Get yourself the kind of soldering iron tip that basically has one (roughly 45 degree angle) flat side (this is sometimes called a "hoof" tip) and put a ball of molten solder on the flat face of it, then drag that ball across the pins. Usually the pins will snap into place nicely. Sometimes you'll get a solder bridge, if that happens just take the iron and "flick" it away. (Sometimes you'll get it on the first try, but sometimes it takes one or two flicks until the bridge is gone.) I've successfully soldered lots of things that I used to think were impossible using this method, like those large microcontroller type ICs with bazillions of legs. And having a magnification device of some sort definitely helps. You can get pretty decent LCD microscopes at really reasonable prices these days. I also have a hand held magnification loupe nearby which I use to double check my work.

Thanks for the advice! I will have to look into magnification and check what other tips I have for my iron. I have tried the "tin one pad then slide the component into place" method before and had good success with that, but the components for that project were much larger.

Tip for the future: Don’t clean bridges like those with braid. Just add flux, clean the solder off your iron (preferably with the metallic wool tip cleaner), and touch again. If it doesn’t wick onto your tip and separate the first time you do this, clean/flux and do it again, this time drawing solder toward neighboring pins to distribute/spread the excess. Most of your joints could’ve used a bit more solder anyway and would’ve benefited from a slightly longer dwell time at that temperature. Your bridges were so small they probably would’ve cleared simply by fluxing and reflowing.

MISTer provides for sweet C64 experience - especially purely for gaming and especially with latest s-video/composite support baked in. It was what made me get in to real HW. I eventfully got Ultimate64 to play SIDs on real HW. MISTer is still superior purely for gaming so I made UltiSID port to MISTer as the UltiSIDs in U64 sounded better to my ears. As for MISTer/UltiSID vs real SIDs... real chips have some quirks like hanging notes and such and they all sound different but music plays more organic with them and in some aspects real SIDs play better - just not always. It is good to have choice when it comes to SIDs when someone likes SID music :)

don't use the iron to transport solder, doing so burns off the flux that is in the solder. heat the joint, bring in your solder, pull away the solder and the iron. for SMT parts I tend to tin one pad first, align the part, reflow that first pad, then solder the opposing pad while making sure the part is aligned. if the part has more than 2 pads, solder the remaining once you are certain you have it aligned fully. a quality stereo microscope helps with parts smaller than 0603, but is not strictly necessary down to that size. 0402 parts are quite easy still with magnification, and 0201 parts are still in the range of "anyone should be able to do this with a few minutes practice". 01005 parts are where the pain is. leave them to the robots.

Flux needs to interact with the solder. What you used was so runny it didn't do anything. That's why your solder was a ball or blob instead of flowing like liquid. It almost looked like it dried out before you even got to it (capacitor). Try Amtech NC 559 V3 TF.

3:50 - "Together, these upgrades (DolphinDOS C64 ROM, drive ROM, RAM buffer, parallel interface) can result in speeds up to 20x stock performance" Wow! That's incredible! So a 1541 drive on a C64 could be up to half as fast as the Apple Disk-II! (Well, according to performance figures I found on the internet and can't be 100% certain of, anyway... Regardless I always love a good joke at the 1541's expense.)

Very interesting video. I had a C-64 when I was young. I wonder how long the MiSTer will use the DE-10 Nano. Aren't there more powerful FPGA chips? Then someone could make cores for later generation consoles, for PS3 for example.

@R4mbo87 Жыл бұрын
I wouldnt bet on seeing ps3 core soon, or even in the next 5 years. The step from ps1 to ps2 was already immense, if you open them up and look at the hardware. People writing the mister cores will have to write all the chips functionalities into working code.

Might I suggest bumping up your iron temp? Your joints look dry and it's taking far to long for the solder to form. Bump up another 20deg or so and be a little quicker and you should get better joints.

If you're selling any other adapters you make I'd buy one. Or even a kit of the parts to put together myself. Not that I really need one but it is a cool little project to use real hardware with the Mister. Between Mister, Ultimate64, C64 maxi, and real hardware/disks I have lots of C64's.
