Need Help In Building A Reflow Station Holder

[juavos]

TITLE SAYS IT ALL

I have the modified griddle ready. I just need something that I can hold the "gun" steady on the CPU/GPU.

Here's my cheap setup...

A clamp, vice and rod.

Thats pretty simple it looks like.. Have you had any luck with the 852A? I have the 852A++ so I think the temps are a little different, but I am going to test it out on a scrap board with the Page 13 profile.

I'm awaiting my 4141 nozzle from Gzetski. Probably lost at some sorting office due to outr stupid postal strikes.

Well a little update.. I tried reflowing it over the weekend (without flux) and thought I had done it pretty good. Well come to find out that it still would not work even after trying it three times. Scrap board I bought off eBay and it had an error code of 0020. So I decided to take the GPU off just to see what temps I had to reach in order to achieve this and its around the 395*C range.

But when I finally was able to take the chip off, it looks like a bunch of the balls are completly gone. Plus it looks like I lifted some traces from the board; which I dont care about this board anyway. But was that from too much heat, no flux; what do you think happened?

I believe it'll take a while until you know what your fully doing, so some boards might not work at all. Practise makes perfect.
Maybe it was a really messed up board.
What profile were you using and what pre-heater?

I have the Wal-Mart griddle that was around $20 bucks. Modified it so that I could use all 8 screws, and the board sits about 1/4" off of the griddle surface. Preheat griddle on 400*, let the board sit there and "bake" for about 4 minutes, then I started the rework with the profile from Page 13 on the other thread. Only difference is I had to go to 390*C on my last temp as my 852A++ is different than the 968 model.

I am about to order the "official" stand that Aoyue sells, because I want more adjustability out of my rework station, as the wood works that I am using now is not going to cut it.. lol

I personally use the 618 Aoyue workstation stand and it works very well for me.

How hard is it to set it up? I see it has a big circle and something that looks like a screw in the middle..

For the 618 Aoyue workstation...only took a few minutes to put it together. Just screw down the cylinder pole to the base plate then slide on the holder. Your reflow nozzle simply slides down into the large center hole on the arm and is held in place by a small set screw in the front....that's it
