(no steel wool, no alcohol) 2012-10-17 11:28 use only wool do some clean. 2012-10-17 11:28 xiangfu: you also don't seem to have sufficient clearance between traces and some bga pads. so unless you expect them to connect or you don't care, you should move the trace exactly in the middle between the pads 2012-10-17 11:29 yes. I am still improving the design now. 2012-10-17 11:29 you'll need the steel wool. first, it removes oxides, which other methods can't touch. second, it leaves small scratches that improve adhesion 2012-10-17 11:29 got it. thanks 2012-10-17 11:30 wpwrak, now I understand more on pcbnew. I have a question on those layers btw. 2012-10-17 11:30 and after the steel wool, you need alcohol to 1) remove the dust/dirt left behind by the steel wool, 2) remove any grease 2012-10-17 11:30 ok. 2012-10-17 11:31 the steel wool should be the fine type, with the steel about at thick as human hair. not the more coarse steel wool where the steel is about 1 mm (for scrubbing pots and such) 2012-10-17 11:31 what's the trouble with the layers ? 2012-10-17 11:32 indeed clean is must 2012-10-17 11:32 (with the steel about at thick as human hair.) got it. 2012-10-17 11:32 the layer.. there are so many layers. like adhes, soldp, silks, mask, eco1/2, 2012-10-17 11:33 what are those layers for. is there any document about them? 2012-10-17 11:33 soldp is for solder paste. that's used when you do the smt at a fab. 2012-10-17 11:33 I understand the 'comments' layer. which is print after solder mask. 2012-10-17 11:34 adhes is adhesive, also used at the fab (for items that need to be glued to the board, e.g., if they're on the bottom side and would fall off during soldering) 2012-10-17 11:34 mask is the solder mask. that's a protective layer applied on top of the copper when making the pcb (at a pcb fab) 2012-10-17 11:35 silks is the silk screen, the white printing you get on top of the pcb (at a pcb fab) 2012-10-17 11:35 none of these usually matter if you make the pcb at home, but solder mask and silk screen must be correct if you have the pcb made at a fab 2012-10-17 11:36 not sure what eco1/2 stand for. i don't use them. i think they're basically for some sort of comment. 2012-10-17 11:38 then you have "drawings" and "comments". one goes to the silk screen, the other is for things you use during design but that don't correspond to any structures on the physical pcb 2012-10-17 11:40 ok. drawings goes to silk screen. 2012-10-17 11:43 in the sense that things you draw on "drawings" are automatically propagated to the silk screen. you could also draw directly on the silk screen, though. using the "drawings" layer makes it easier to hide your drawings, when the pcb gets crowded and you want to display only the things you're working on at the time. 2012-10-17 11:43 ok. I understand the adhes, mask now. 2012-10-17 11:43 you just answer what I want ask. (can you read my mind?. that is scare :) 2012-10-17 11:44 heh :) is noticed that my explanation was ambiguous 2012-10-17 11:44 what is the soldp for? like some pad have tin, and some not? right? 2012-10-17 11:47 solder paste is a cream that contains solder (tin) 2012-10-17 11:48 at an smt fab, it is applied on top of smt pads before placing the components 2012-10-17 11:49 then, when the pcb is put into the oven, the volatiles in the solder paste evaporate and the tin melts, making the solder bonds 2012-10-17 11:49 yes. understand now. 2012-10-17 11:49 you sometimes also use solder paste for manual smt, but most things can be done without it (it's a bit messy to handle manually) 2012-10-17 11:50 e.g., it's useful for soldering crystals. not sure if you need it for bga, too. i never tried to hand-solder bga. 2012-10-17 12:04 ok. 2012-10-17 12:07 jluis_ has quit [Ping timeout: 245 seconds] 2012-10-17 12:11 I will try hand-solder bga without solder paste this week. :) 2012-10-17 12:11 I already have 5 slx9-ftg256 chips on my desk. 2012-10-17 12:20 jluis_ has joined #qi-hardware 2012-10-17 12:34 lekernel has joined #qi-hardware 2012-10-17 12:36 jurting__ is now known as jurting 2012-10-17 12:52 urandom__ has joined #qi-hardware 2012-10-17 12:52 GNUtoo-desktop has joined #qi-hardware 2012-10-17 12:55 xiangfu has quit [Ping timeout: 246 seconds] 2012-10-17 13:06 GNUtoo-desktop has quit [Remote host closed the connection] 2012-10-17 13:09 jurting has quit [Remote host closed the connection] 2012-10-17 13:14 GNUtoo-desktop has joined #qi-hardware 2012-10-17 13:15 Hoolxi has joined #qi-hardware 2012-10-17 13:23 woakas has joined #qi-hardware 2012-10-17 13:29 cladamw has joined #qi-hardware 2012-10-17 13:30 The build was successful: http://fidelio.qi-hardware.com/~xiangfu/build-nanonote/openwrt-xburst.minimal-20121016-0538 2012-10-17 13:36 erikkugel has joined #qi-hardware 2012-10-17 13:45 urandom__ has quit [Quit: Konversation terminated!] 2012-10-17 14:10 dandon has joined #qi-hardware 2012-10-17 14:10 jekhor has joined #qi-hardware 2012-10-17 14:29 Hoolxi has quit [Remote host closed the connection] 2012-10-17 14:54 jluis has quit [Ping timeout: 260 seconds] 2012-10-17 15:24 jekhor has quit [Ping timeout: 255 seconds] 2012-10-17 15:42 emeb has joined #qi-hardware 2012-10-17 15:47 arossDOTme has joined #qi-hardware 2012-10-17 16:09 cladamw has quit [Quit: Ex-Chat] 2012-10-17 16:48 jekhor has joined #qi-hardware 2012-10-17 17:08 urandom__ has joined #qi-hardware 2012-10-17 17:23 jekhor has quit [Ping timeout: 268 seconds] 2012-10-17 17:38 GNUtoo has joined #qi-hardware 2012-10-17 17:58 guanucoluis has joined #qi-hardware 2012-10-17 18:04 guanucoluis has quit [Quit: Leaving.] 2012-10-17 18:04 guanucoluis has joined #qi-hardware 2012-10-17 18:12 guanucoluis has quit [Ping timeout: 264 seconds] 2012-10-17 18:24 pcercuei has joined #qi-hardware 2012-10-17 18:44 scientes_ has joined #qi-hardware 2012-10-17 19:03 lekernel_ has joined #qi-hardware 2012-10-17 19:03 lekernel has quit [Ping timeout: 246 seconds] 2012-10-17 19:04 lekernel_ is now known as lekernel 2012-10-17 19:04 scientes_ has quit [Ping timeout: 244 seconds] 2012-10-17 19:12 jekhor has joined #qi-hardware 2012-10-17 19:17 GNUtoo-desktop has quit [Quit: [INFO] fsogsmd : received signal -11, exiting.] 2012-10-17 19:18 kristoffer has quit [Quit: Leaving] 2012-10-17 19:23 flstd has quit [Remote host closed the connection] 2012-10-17 19:27 pcercuei2 has joined #qi-hardware 2012-10-17 19:27 pcercuei has quit [Read error: Connection reset by peer] 2012-10-17 19:27 pcercuei2 is now known as pcercuei 2012-10-17 19:54 pcercuei_ has joined #qi-hardware 2012-10-17 19:54 pcercuei is now known as pcxperia 2012-10-17 19:54 pcercuei_ is now known as pcercuei 2012-10-17 20:42 pcxperia has quit [Quit: Bye] 2012-10-17 20:53 jluis_ has quit [Ping timeout: 245 seconds] 2012-10-17 21:02 jurting has joined #qi-hardware 2012-10-17 21:06 jluis_ has joined #qi-hardware 2012-10-17 21:14 GNUtoo has quit [Quit: Program received signal SIGSEGV, Segmentation fault.] 2012-10-17 21:19 heberth has joined #qi-hardware 2012-10-17 21:21 erikkugel has left #qi-hardware [#qi-hardware] 2012-10-17 21:46 [commit] Paul Cercueil: Removed unused class variable 'useRamTimings' from LinkApp (packages) http://qi-hw.com/p/gmenu2x/c1a95a2 2012-10-17 21:46 [commit] Paul Cercueil: Add "editable" parameter: when "false", the link can't be modified.
