2014-01-07 04:03 "GA SMD Soldering Paste Flux Grease" = ??? ;-) 2014-01-07 04:03 it looks like flux, though 2014-01-07 04:03 solder paste would be greyish and opaque 2014-01-07 04:04 of course, grease could just look like flux. let's hope it's not that ;-) 2014-01-07 04:04 RMA suggests it's indeed flux. not the nicest kind but usable 2014-01-07 04:05 RMA means it's sticky. its soldering properties are great but it's a pain to get rid of 2014-01-07 04:05 the board -- http://ctrlv.in/280074 2014-01-07 04:06 the one i like the most is "water soluble". it still helps a lot with soldering but it less sticky and can be removed with relative ease 2014-01-07 04:06 http://ctrlv.in/280075 2014-01-07 04:07 so normally the best way is apply flux first and then tin it right ? 2014-01-07 04:07 there's a third kind, "no-clean". you supposedly don't have to remove it though some experts say you really should anyway. i didn't find the one i tried to be very satisfying in terms of helping with soldering 2014-01-07 04:07 yes 2014-01-07 04:07 ok i will try on the test circuit that i have 2 on my board (on top and bottom) just to make sure :) 2014-01-07 04:08 looks pretty good 2014-01-07 04:09 i learn now that to save on etching combo i will use sharpie so that it will not be dissolved that way i can have my combo HCL / H2O2 longer :) 2014-01-07 04:10 the track i'm using 0.4mm 2014-01-07 04:10 as recommened by the expert here :) 2014-01-07 04:10 black and blue sharpie works other colour does not work 2014-01-07 04:10 just a tip :) 2014-01-07 04:15 wpwrak_: something like this http://www.ebay.com/itm/SRA-80-WATER-SOLUBLE-FLUX-PEN-Great-for-Solar-Cells-REFILLABLE-/110922677662?pt=LH_DefaultDomain_0&hash=item19d381bd9e ?

2014-01-07 19:56 I assume 2014-01-07 19:56 I did push the setup and other cleanups, those are squashed into the commit 2014-01-07 19:56 ok 2014-01-07 19:56 I thought you had more pending 2014-01-07 19:56 I started on dma engine support for jz4770 once, but didn't get very far 2014-01-07 19:57 https://github.com/gcwnow/linux/commit/0a1be0ed302f2cb7f4c8a7b93402f1fcd102e1d0 2014-01-07 19:58 this describes all the changes 2014-01-07 20:01 jekhor_ has quit [Ping timeout: 260 seconds] 2014-01-07 20:14 pcercuei has joined #qi-hardware 2014-01-07 20:15 pcercuei has quit [Client Quit] 2014-01-07 20:15 pcercuei_ is now known as pcercuei 2014-01-07 20:24 FDCX_ has joined #qi-hardware 2014-01-07 20:37 Luke-Jr has joined #qi-hardware 2014-01-07 20:43 jekhor_ has joined #qi-hardware 2014-01-07 20:54 whitequark: wait, 31kg? wasn't that the bogus weight for your CNC? 2014-01-07 20:55 now you know why they titled it as being 31kg - they think one such package per month is enough ;-) 2014-01-07 20:57 HAH! >>W.
