Hi folks!

I've been busy the last few days trying to make one good BVision out of two poorly ones. Beware hardcore hardware pr0n alert! :cool: Here are a few pics to show what I did...

Here are the two units, the one to the left is my DOA evilbay jobbie, the one to the right is the known working unit I got from Keith in the hopes of being able to transplant the miniPCI connector over...

As you can see, its not pretty!

Looking through my works 2x zoom lens I clean up the pins.

This is the connector I have to take off... how on earth shall I do it?! ....


http://lh5.ggpht.com/_fdR0Byi9CIY/TSzW2Uu3MHI/AAAAAAAAA6o/GjYYriYG9A4/s640/10012011788.JPG


Heatgun the sucker! I applied 350 Deg C temps on low airflow for 15 seconds to the other side of the board and......

PLOP! It fell clean off. Not recommended on a working BVision folks!

Cleaning up the pins.

OOH! I noticed something else... a missing cap!


http://lh4.ggpht.com/_fdR0Byi9CIY/TSzW4uDJ0MI/AAAAAAAAA6o/dxVNC5t7JYQ/s640/10012011792.JPG


So swiped one off the duff BV :)

Using my bare peeled eyes only to line up the connector on the working board.

Cripes, there is a lot of work to do here...

http://lh5.ggpht.com/_fdR0Byi9CIY/TSzW6cw7zVI/AAAAAAAAA6o/9V0F_hIMsMA/s640/11012011795.JPG


A quick shot of my humble gear before I get down to the dirty work.


http://lh6.ggpht.com/_fdR0Byi9CIY/TSzW66YibII/AAAAAAAAA6o/E_2d_-3YIKs/s640/11012011796.JPG

I'm on my way, its not too bad actually! Using 0.2mm solder + tip.


http://lh6.ggpht.com/_fdR0Byi9CIY/TSzW7WwgHAI/AAAAAAAAA6o/HnpahDUv5YA/s640/11012011799.JPG


All pins done, now to tackle the broken tracks...


http://lh4.ggpht.com/_fdR0Byi9CIY/TSzW7rWd_sI/AAAAAAAAA6o/0qxVjxrET1Y/s640/11012011803.JPG


Hmm.. its a bit of a cludge, but I used some small pieces of bent wire. It was a tad fiddly getting a good joint on the old points so took a bit of time fiddling with the tweezers and solder. I got there in the end even if its a little lumply.


http://lh6.ggpht.com/_fdR0Byi9CIY/TSzW8akEVbI/AAAAAAAAA6o/eS6mMY8XWUA/s640/11012011804.JPG


Soldering done! Now to laquer....

Masked chip tops and connectors ready for spraying.

Not much to say except that...

YOU ARE THE AMBASSADOR OF THE KWAN man!
Outstanding piece of work that most of times leads to headbanging on the wall.

That was indeed a nice piece of artwork pr0n just before I go to bed.

Wow, I wish I had your patience - this would have been a "send away" job for me.

Oh, and wonderful work setup you have there - a true Amiga guru mod centre - my hat off to you sir.

Really nice and clean work! :thumbsup:
Congratulations.
Microscope or magnifying glass + A LOT of patience are the best tools - I agree.

Cheers for the praise guys, I must say I didn't know if I could manage it. I certainly took my time and made sure each joint was good after i'd finished so when I took it home and fired up I was extatic! I am always very negative when i've done a job, like i'm SURE it will break this time, then I get all surprised.

Anyway glad the pr0n was enjoyed by all :)

HAHA! Yeah, i'll never live the dancing outburst down, no matter what I do, I can't better that :D Just wait until next R3play and i'll bust a few more drunken dance moves :D And as long as I have had at LEAST 4 pints i'll deffo do a little jig to some of DJ Echos Choonz in the R3play hall.... and then hide somewhere HAHA!

Hey Mate,

I'm sure you will, but I just fitted a little VGA Heatsink/Fan to the Permedia chip.

Before after a session it was too hot to touch, but with this little Fan even after a Quake 2 session its cool to touch, amazing.

And this was with the Floppy in place and Desktop Case closed :)

Have fun with that little fella!

Steve.

Hiya Steve

Aye mate, I have a very nice heat sink to put on the Permedia chip and the one across from the VGA connector. I also have a set of DDR RAM sinks but I realise I wont be able to fit them as the clockport expander is in the way :( Those RAM chips also get a little bit hot too, I'm hoping that the way i've positioned the three case fans will be enough to keep it all cool. Thermal tests will follow the hardware setup. I want to determine if I can actually be cheeky enough to reduce the fan speeds as they are a tad noisy. Of course only if I get cool enough temp will I attempt to slow them down. Noise is a small price to pay for such a beast! :)

Yep, thats when you know mines got some grunt under the hood when the fan kicks in! Before that you just think its a normal A1200!

The Chipset Fan I got is pretty much silent, so thats nice and I'll prob's get some VGA heatsinks on the Ram chips and the Chip in the bottom right of the card.

My BPPC fan is pretty loud tho, Stachu is sending me a brand new fan to replace it with so hopefully soon I shall have a pretty quiet setup.

Seeing your project burst back into life makes me want to get USB in there though!

Steve.

Congratulations on such a wonderful repair Phipscube :thumbsup:

That was bloody fantastic M8, I enjoyed reading this thread from the link to it at EAB, the pictures of the stages and problems with broken tracks and how you sorted them out are a great reference for anyone who needs to fix a broken track or something as advanced as replacing that sort of surface mounted socket. I particularly like the way you removed the connector, that was something that I can maybe try out on next time I want to salvage an SMT connector :thumbsup:

Phipscube I was reading this by chance, and after some photos and so, I go to see who is the man... :lol:... It had to be you.
Great job!

welcome back my friend :-)

awesome work you've done.
I take it your fingers has been itching to get this done in the last 4 months.

when you have the tools, everything is easy :-P

@darkage
the usb microscopes from China doesn't display silver colours properly, and colours are pixelated.. but what do you expect for $1 + PP ? :-)

Thanks Guys! :)

Steve, aye the subway is awesome! :)

Allen1, I tend to use that brutal Heatgun method on old laptop boards. I have a little box full of smd connectors, ide, vga, etc just for whatever, and they fall off in great shape too.

Retrofan, i'm glad you got your clockport fixed too mate! that was quite a hairy solder job too, great work!

Tomse! Your dead right mate! I had 4 months worth of GNNNNNN in me bursting to fix that BV! :D I was determined! I'll be in touch through PM mate, we need to meet up and mess around with some Amiga HAKZ000RZ! :)
