    Thanks for watching this video.
    Update: I used an incorrect part in my build for the real time clock (thanks Keir Fraser!) so make sure you use a RTC62421 or RTC72421 as listed in the project! I've just ordered replacements.
    If you wish to purchase the board then the link in the description goes directly to the creators webstore on PCBWay. If you order from that page then the creator (SukkoPera) will get a percentage. The page also has a link to SukkoPera's github page.

      Hi Betty! Thanks for watching! When I’m soldering SMD I use a small digital microscope, but it doesn’t work well for filming because it gets in the way. Solder is a thin tin leaded alloy and the station is a temperature controlled Tenma unit that I’ve had for years. I am planning a tools video real soon so watch this space!

    • @MarkFixesStuff
      @MarkFixesStuff  4 роки тому

      Yeah. Apparently I should be using the gunky flux paste as well. I usually do hot air on stuff like this to be honest. Wanted to just use an iron for this vid because not everyone has or wants to buy a rework station. Drag soldering packages with flat pins works great with the topnik liquid flux. Just the J leg packages don't. I think the curve is the issue.

      I actually have some of the Amtech stuff. These J legged packages are a pain anyway, but I’ll try that on my next SMD project. Is it better because it keeps it’s form?

Newark has LY62W51216 , which is a 512kx16 SRAM 44 pin TSOP packaged chip, priced at $4.87 single quantity.Comes in 60 and 75ns speeds, 5v. Will be perfect for a similar board.
