My First WOPL 400 Series 2 Build

Soldering in a chem lab is probably sub-optimal as well...
 
All the socket cups in. Started the PEM nuts. Just did half the board, Wondering not enough solder, Too much solder, what do you say? I say it's close enough for the girl I run with...:D

Here's a few pics.

Some final pictures of the Backplanes. I greatly appreciate everyone's help in getting me to this point of the build. Is Anything missing or need correcting before I continue on to the wiring? Thanks a lot guys

Hey Guys,

When I started this adventure, I was to post plenty of pictures and ask any questions when unsure. I've asked honest questions, Wanting to know if what I've done so far was the correct way, and I've gotten little or no answers. I apologize if I came across as a know-it-all in a previous post. I didn't mean to because I don't. I was trying to add a little humor. So, I'm asking again. Is there anything in the work I've completed on the Control Board or the Backplanes that needs correcting? Before I move on. I want to do things the right way. If anyone would still like to lead in the right direction, I would greatly appreciate the help. Thank You

Doug

Hi Doug
This group is not bashful and would have criticized if it was due. So far your work looks very good. Nice solder joints and nice clean board after the soldering job.
 
Doug,

First, thank you for posting your build pictures, it's always interesting reviewing other peoples experience building these projects. Having said that, my day job has been crazy busy and I have not had the chance to post on this forum lately.

Overall your progress looks very good and I do not see anything requiring immediate correction before proceeding.

The only feedback I have relates to the PEM nut soldering. It's difficult to accurately evaluate the solder joints with shadows and reflections on your somewhat low resolution pictures, however see below for examples of a few I would touch up with a hot iron and liquid flux. The edges appear rough and jagged. See second picture for example of what you should shoot for in solder quantity and appearance.

Doug, I've read the whole thread over and your prose is very non-confrontational. Nothing to worry about there.

And believe me, WE ALL understand the anticipation and building excitement, and that creeps into your posts...and that's a good thing, if it wasn't you're a BOT!!

Hexis22, that's some NASA level soldering there!

Thank you Joe, For the kind words. With all the threads I've read since joining. I could see the members aren't bashful at all. That's the reason I was wondering if I messed up.

Thanks Eric,
That's what I'm talking about. Tell me when my work looks like Ca-Ca. The last pic was my first try at the PEM nuts. I think the rest of them look a little better after I calmed down a bit. Nowhere in the neighborhood of yours though, Maybe one day. What are you using to take your pictures. I've taken tons and can't get them as clear as yours when zooming in. Again, Thank You for your help.

Thank you Sir, I am really enjoying this build. looking forward to finishing. Hopefully with everyone's guidance it will be awesome. I appreciate all the members for the help and support they offer.
 
Hey Guys, its been a few days since I posted any pictures of my progress. Taking my time and doing a lot of reading on the assembly procedures. I got the Backplanes wired up and started assembly of the new chassis. Working on the Transformer getting it ready.

Thanks for looking.....

A few comments:
- Check the wire lengths on both left and right boards.
- Right board has wire lengths very short and most likely must be updated:
- GND_IN1, GND_IN2
- Fused_B+_IN

Now is a good time to add a Green wire to the right board at Fused_B+_Out for the DCP board.

OOPS.... I labeled them wrong in my previous post. The top picture is right board and the bottom picture is the left board. I'll add the green wire to Right B+ out before I do anything else. Good eye, Thanks Eric...


This look more gooder...
