Hello. I first placed a query in the topic
, but then i noticed, that tutorials are no question area so im sorry about that.
I plan to start processing BGA chips and other ICs this year. I studied a lot of procedures and prepared a plan that I want to try and I would very much like to know your opinion. This is a pre-chemical treatment:
- pyrolysis and incineration
- ball mill grinding
- sieving through a 2mm sieve - to remove thermal spreaders
- removal of the finest fraction using bucket separation as used by Successful Engineer in this video: https://youtu.be/BQFNG_FXgZg?t=1037
- drying and sieving with 60 - 100 sieves + magnetic separation
- processing using sluice with dream mini mat like this one: https://paydirt.se/index.php?route=product/product&path=83_97&product_id=423 Do you think this mat is good option for catchning bonding wires?
- then maybe concentration on the miller's table, but again I don't know if it's suitable for working with bonding wires.
I originally planned to use the Gold Spiral Wheel, but with postage + VAT it's a very expensive solution for me in Czech Republic.
Do you think this could work or if you made any changes. Thank you so much for your tips, I can't wait to try it.
