some advice for those needing to pull their ba6110
it can be difficult to get all the solder off of all nine pins
to get a clean pull of the chip
you need to do a good job or you could lift the traces
so id suggest taking a pair of diagonal cutters and cutting
the chip away from the leads
leaving the leads as long as possible
you can then use your solder sucker or solder wick to
clean away as much solder as possible
and then heat each lead one at a time whilst pulling gently
with a pair of needle nose pliers

I already got some on order from here:
http://mcm.newark.com/NewarkWebCommerce ... search&y=9
Hurry up.. there are only 6 more available. Hopefully they are not the bad datecode. I will probably send my extras (I got greedy and bought 4) to limor once mine is working.

i have enough extra to replace all of them. i bought my stock from newark. so there is a very good chance that you got the same batch.tsheets wrote:I already got some on order from here:

datecodes..
Limor was right... all 4 parts I got from Newark were the bad datecode... 420 178. Don't bother with these.
