Hi All - I am hoping someone can help with some pointers (complete noob here!)
I have recently purchased a Scotle HR460 BGA reball machine (it's a bit old and I think the company no longer exists either), but as far as I can tell it is a competent and unmolested machine that should be good enough for my needs.
My biggest problem is that it came with no profiles, and I must re-create all of them from scratch, something that is very scary for someone that doesn't really know what they are doing.
The simple stuff like a small memory module isn't a big deal because there are a few example profiles in the manual – but for more than that the manual is no help as it is very basic. Also, it does not contain any of the advanced features, so I have no idea if the fan speed that is programmed in is fast or slow or if it needs to change based on the application.
Primarily I bought this style machine to do socket replacements on AM5 and LGA1700 boards, but after what looked like a promising start with a profile that worked well for desoldering, I am afraid I might have become overconfident and ruined a Strix Z690 board as the same profile was not OK for soldering a new socket back.
This is the complete profile that I used:
The last number in the corner that is in glare is 250C.
Unfortunately, I am not 100% sure how the board died, it still turns on at it doesn't trip OCP, but all the diagnostic LEDs stay off while before it would show that it got stuck on RAM (the missing pins were RAM-related). It might be that I overcooked it or when I tried to turn it on first time it had an internal short and that was that. Regardless with nothing to lose I un-soldered the CPU socket again and it was immediately clear that only the corner balls had melted and made good contact while all the others were untouched. I do not believe the board is warped so I don't think that was the issue. I have read some older posts on here with someone else complaining of the same issue, I don't know if they fixed it or not - I did send them a PM.
At this point I am just hoping that the test CPU and memory did not get damaged in the process…I will know for sure in two days' time when I get a new motherboard delivered as instead of buying a Celeron or something I used an I7 13th gen for testing.
Does anyone have a similar machine and have you developed your own profile that you know works for various applications? Obviously, a socket soldering profile would be amazing but even a 50 x 50 GPU or large SMD profile I think would be immensely helpful in diving what sort of settings I need.
I can set 6 stages for my machine and the temperature, rate of climb and hold time can be set independently for the top heater, bottom heater and additional IR heaters.
The other advanced parameters such as fan speed and segmentation parameters I do not know how to adjust so I left them alone – if they are the same as they left factory, or the previous owner has changed them I have no way of knowing. I was tempted to factory reset the machine hoping that the profiles would show up, but thankfully I checked online, and it seems other people that have done that ended up with a “blank” machine without any software so I won't be doing that.
Sorry for the long post and thank you for reading!
