BGA own made(new project)

Postby aisikterix » Sun May 18, 2014 11:26 am

Hi guys. I did it myself here: I took an old box computer. Some of the mechanisms worked alone, others on request.I have a few questions and hope for some help.
1.Can I use controller rex c700, instead of C-100
2.of how far the heater from the motherboard
likely there will be other issues but later.
accept any comments about my station

Looks like the c700 controller is just like the c100, just bigger. If it has relay output, then you should mod it like
people do with the Rex c100 to change it from relay output to logic output to be able to use standard DA type SSR.
Most people use straight wire jumpers for that mod, but it is better to use resistors. Like 200 ohm for jumpers.

The distance between the pcb and bottom plates should be as much as you can get away with. Depends on the strength
of your bottom plates. In your pic with jig sitting on machine looks way too low. It will heat more uneven so close and
not utilize the radiation from the plates. I use hot air for top heat, but if you read posts on the forum, you will see that
the guys on here using IR top heaters report they have the best results using top IR heat from 35mm to 40mm above pcb.

Looks like you did quite a bit of work fabricating your top heater and support. Looks good.

I recognize the schematic. Unelma mods from FB. I can't read the rs232 labels, so can't tell if it is his older copy. He
revised the rs232 connections later.

make a change: I changed thermocontroller with c100

I have a question:
of that place so you need to connect the cables.
The controller outputs are 4 (+)-5 (-)?

Very nice project :) Where did you get the top arm mechanism?

As you can see in that schematic you are using, that controller is a Rex C100 with "Relay"
output that has been modified. The relay has been removed and a couple 200 ohm resistors
used as jumpers to jump 12vdc signals that controlled relay directly to the #4 & 5 terminals
so it can control a standard type DA SSR with terminals 4 & 5. 4 will be negative and 5 will
be positive. Most guys use wire for the jumpers, but I know the one in the pic has resistors
because the guy that owns it does that to all his c100's. If you scroll down to the last part of
this page of this thread, you will see how someone removed relay and put in jumpers. Terminal
3 of the C100 will no longer be used.

Thanks friend(code0102stinks), today I will open the controller and modify it. I would put 200 ohm resistors.

Not to shabby on the price.
How well does it work though?
I was thinking about building myself a preheater and using my hot air for the top heater.
