Hello All,
Three new sets of reliability problems in a day? Maybe the trend for always cheaper PCB's includes some quality issues?
Don't guess this is the last time getting more for less causes problems.
Personal results may vary.

Subject: [TN] Cleaning of BGA sites after component removal
Hi Technos,
I don't know why, but lately we get more BGA rework contracts. Some
customers come with batches of 40 boards, which I find huge for rework lots.
And we noticed that it takes a lot of time and solder wick to clean the
pads. Not to mention the scratched solder mask and the pads coming out of
the substrate.
What other cleaning methods or tools are there?
Many thanks,
Ioan
