@Chain

congrats!!!

a very nice job indeed, I just finished de-soldering an MCA200 pin female... lost a couple of pins, but lucky me had a few spare

Oli_HD · 03 March 2008, 01:45

If we are doing a group order I would have four.

(Motherboard connectors)

PS: Great job desoldered that connector!
You were able to remove all the solder from each enough to just lift it out?

yes, first ive tried soldering iron&braid but it wasnt enough to pull all solder out. Hot air with classic desoldering pump works great. it can even desolder three pins in one go

I will have to give that a go.
Removing SD-Ram (pc100 stuff) is the easiest, the plastic actually peels off leaving just the free-standing pins.

I have to say I only use my hot air station for doing surface mounted stuff and I dont think I own a standard desoldering pump.

Zetr0 · 03 March 2008, 23:56

Today i de-soldered

2 Socket 3 ZIF sockets
1 Super Socket 7 ZIF Socket
6 72pin Ram ports

all with hot air and solder sucker (spring manual pump) and a sh*t load of flux!!!!

my thumb is killing me..... but i have my boxes full of loads of SMD stuff from radial caps to tantalum networks!!

my dram and ram boxes over runneth!!!!

i must take some pics...

Chain · 03 March 2008, 23:59

see, it works

good old sesoldering pump (dont tell it to my thumb)

ive desoldered bad fast slot from mobo today. Tomorrow i will finally solder back a good one from Hodkinson. If i will have camera handy i will take a few secs movie.

alexh · 04 March 2008, 00:24

I've not used a solder sucker for years, not since I discovered solder wick (braid). You said you couldnt get it out with braid?

Zetr0 · 04 March 2008, 00:30

@Alexh

I have two types of solder braid, 0.8mm and 1.5mm

now both are declaring them selfs as no-clean soldermop etc.

however even when i lump a load of flux down they just wont suck enough solder up....

i found the method with the pump, like Chain mentions, when i desoldered a PCI port from AMP, the method wasn't 100% as about 4 pins were left in the board, but these were easly removed and re-pinned in the port.

but with this method the above i managed today without any fuss...

I have searched youTube for methods with solder braid / mop / wick but i cannot find a method that i can get to work for me lol... so I must be doing something fundamentally wrong..

any pointers?

try it with 68040

. There is another trick howto find stuck pins - twiddle every pin with pair of twincers/tweezer. It some ofthem are still stuck, apply solder in it and try to suck it again. Push component thru only after all pins are free and you will not damage a board.

Zetr0 · 04 March 2008, 11:40

@Chain

indeed this method of re-solder stubborn pins and then suck them back up works well.

I managed to retrieve two socket 3 (040 / 060 compatible) ZIF sockets with no pin loss!!! whoot say I!!!

alas..... my thumb is still in pain... I went through 3 or 4 dead motherboards (486/586) for components over the last couple of days... I am about 75% of the way through...

yep.... i am getting pissed at manual solder sucking.... i am almost tempted to use a straw!!!!

I have to admit its a great way to learn how to use the hot air to de-solder!

Started small in video card, taking the memory and controller chips off... then onto the older motherboards.

when i first started on the bigger boards I was blistering the board and taking forever on a 72pin memory socket, now i can do it in under 5 mins with all pins still attached and no board blistering...

I have to admit though the secret to the recipe is flux paste.... OMG!!! its heaven!!!!

Jope · 04 March 2008, 12:15

Flux paste is good.. I don't have any at home, so I just heat them up and dab a little bit of fresh solder on all pins before I start desoldering.

Oli_HD · 05 March 2008, 21:48

I use a but load of flux and a solder mop but removing simm slots and fast slots normally means killing the connector.
If a "sucker" and hot air gun does that good a job I will try.
(I removed some SOIC's and PLCC's today with the hot air gun but thats a piddle in the park compaired to THP)

Zetr0 · 06 March 2008, 00:17

@Oli_HD

I removed two SDRAM 168pin ports yesterday, using the hot-air + flux paste + solder sucker.

I spent a bit of time around 15 minutes ish on each, and I only lost one pin from one of the ports... I found it and hence re-pinned it

alas my thumb hurts... its a difficult choice ..... guitar hero 3 or de-soldering..... damn..... not sure ....

billt · 21 March 2011, 19:58

Which connector goes on the motherboard, and which on the acceleartor? I did buy a few of one or the other from Jens S. some years ago, I think before RoHS, and bought a fried A4000 desktop motherboard more recently to get a motherboard connector. I'm surprised to find a recent discussion and that they are still made, I'd just like to know which exact product number goes on each end of our stuff.

And if any of you bought an order of RoHS compliant ones and someone has a spare set or two I may be interested.

Very interesting..

@ OP

Have you tried contacting Foxconn themselves? BTW they are the sole manufacturer for Apple iphone and ipad afaik.

ShK · 09 July 2014, 13:19

Sorry to bring up an old thread, but where can I find accelerator/cpu board male (32bit Local Slot) KEL 200-pin connectors for 4000 accelerator with a missing cpu connector?

tnt23 · 09 July 2014, 15:10

Shk, I have placed an order for a small number of connectors, to be delivered in ~10 weeks. If you still need one by that time let me know.

ShK · 09 July 2014, 15:28

I sent you a private message.

tnt23 · 09 July 2014, 15:31

PM answered.

tnt23 · 10 July 2014, 08:27

Regarding the ones I have ordered, they are KEL 8817-200-170S-F. I do hope they are the right ones. Attaching a page from KEL connector series datasheet for reference.

Let me keep this thread updated, although KEL is not FOXCONN
