Practising with the Achi IR6500

Sometimes I wonder why I bother.
My first BGA removal with the IR6500 from a plasma control PCB went perfectly, but as it was a first go I didn't record it............
I then spent 2 days and 12 videos trying again with another PCB, at every attempt something daft went wrong.
I managed to get this video tonight to show that it works just fine.
The standard PTN 2 profile was fine for a smaller PCB is fine.
Bottom heat at 120 and top at 220.
For larger PCB's and chips with ground planes an increase is required. In my case to 160 bottom heat, 230 top heat for a QFP with ground plane, again not video's.........
For this BGA a lower figure like the original 220 would have been OK but a raise in the lower heat to 150 perhaps.
Note the melted plastic at the back but this is a scrap PCB and I wasn't going to have any more adhesive foil just fall off once up to temperature.
The thermocouple needs to be mechanically coupled on some sort of arm so it can't move. Perhaps like the ERSA IR500.
I will get something made up.

Came off nicely, minimal work to put the new one on there now. Now all you have to practise is reballing one.

would be interesting to see whats happening with a Flir.

[@rezakianpour9668]

the upper zone look so much bigger than the size of regular chips. is it possible that plastic parts near bga chip melt down due to the size of the upper heating element ?

[@fazbari8088]

Hi Trevor , how come you have upper fan running while in pattern 2 mode , thought fan was only for cooling upper heater when bga process finished.

[@christiandyczka7625]

Hi :-)
Can you tell us your bga profile settings?

[@catalinnicolaevici2061]

I wanna buy one of these

[@isaiasrodriguesdossantos646]

Hello Trevs would you tell me your BGA profile I have exactly the same Revork station, That would be great Thanks.

Hey would u help me with the same machine please

[@bitsnbobs1969]

did you master this i might buy one

[@Trevs-Shed]

I moved on to other repairs that didn't require this equipment. So, no.

No se para que hacen estos videos sino ayudan en nada.
