2014-02-14 11:52 yeah 2014-02-14 11:52 good thing I have two dozens of .2mm flying to me :p 2014-02-14 11:52 drilling a via hole to contact a inner layer with your hole plating is not exactly easy 2014-02-14 11:53 well, not easy. but doable 2014-02-14 11:53 maybe 2014-02-14 11:53 do I understand it right... to make such a blind via, you need to have a pad (filled area of copper) on the inner layer 2014-02-14 11:53 depends on precision of your drilling process and quality of your PCB material 2014-02-14 11:53 then you drill from the outer layer right up to this filled area 2014-02-14 11:54 and then you do electroplating on that hole, connecting traces on outer layer with that area on inner layer? 2014-02-14 11:54 well, yes, for embedded vias that's what you do 2014-02-14 11:55 there's something else? 2014-02-14 11:55 usual (simpler) way is to drill all through the whole lamiate stack and thus expose a copper surface of the drilled-through inner trace to the hole's surface 2014-02-14 11:56 (copper surface) you expose the _side_ of the copper layer, right? not its _surface_ ? 2014-02-14 11:56 cross-section of it 2014-02-14 11:57 and that copper surface of the inner layer trace in the drilled hole has to be quite clean and tidy to make for proper hole copper plating making contact to the inner trace 2014-02-14 11:57 yes 2014-02-14 11:57 that's how vias usually work 2014-02-14 11:58 right. just was making sure 2014-02-14 11:59 you can crate an inner stack of just maybe 2 or 4 copper layers, do the vias, then laminate further stacks of FR and copper on top on both sides and create further vias when outer copper layers are involved 2014-02-14 11:59 create 2014-02-14 12:00 you shall fill the vias prior to laminating further layers, or your PCB will go popcorn 2014-02-14 12:01 fill the vias? 2014-02-14 12:01 yes 2014-02-14 12:01 you usually fill vias 2014-02-14 12:01 with either copper or varnish 2014-02-14 12:02 particularly when you need in-pad vias 2014-02-14 12:02 filling them with copper sounds painful 2014-02-14 12:02 unless really small vias 2014-02-14 12:06 http://www.google.de/images?q=buried+via 2014-02-14 12:07 http://en.wikipedia.org/wiki/Via_(electronics) 2014-02-14 12:08 I see 2014-02-14 12:08 http://en.wikipedia.org/wiki/File:Bga_und_via_IMGP4531_wp.jpg 2014-02-14 12:08 how do you even make such cuts?

2014-02-14 12:17 you probably need special toolbits for such work 2014-02-14 12:18 sure. but it is hard to imagine metal regaining its properties at 70K 2014-02-14 12:18 though the age old urban legend about cooling down steel of e.g. padlocks with N2 and then crack them open with a small hammer is just BS 2014-02-14 12:18 is it? 2014-02-14 12:18 yes, sure 2014-02-14 12:19 otherwise, which maerial would you use to *produce* and *contain* liquid N2 in it 2014-02-14 12:19 http://www.youtube.com/watch?v=XgXk_Yzw0nU 2014-02-14 12:19 freezing makes materials less elastic, but not weaker 2014-02-14 12:20 maybe you don't smash whatever you store N2 in with a hammer 2014-02-14 12:20 (not elastic) but I see your point 2014-02-14 12:20 a steel rope able to lift 1t isn't breaking at 100kg when you cool it down 2014-02-14 12:21 but if you put it under stress, it handles it much worse 2014-02-14 12:21 so it will *hold* 1t but probably not be able to *lift* 1t under same conditions 2014-02-14 12:21 eintopf has quit [Ping timeout: 253 seconds] 2014-02-14 12:21 and I honestly doubt a steel rope would break on bending it, even when cooled down to next 0K 2014-02-14 12:21 you tempt me to get some N2 and show you 2014-02-14 12:21 DocScrutinizer05: there are milling concepts using ice 2014-02-14 12:22 eintopf has joined #qi-hardware 2014-02-14 12:22 because properly cooled it seems ice could be harder than steel 2014-02-14 12:22 that's the point 2014-02-14 12:23 steel won't suffer much elasticity loss from cooling it down, I think 2014-02-14 12:24 just like it's not getting considerably more elastic by heating it up a 250 or 400 °C 2014-02-14 12:24 aka K 2014-02-14 12:24 it softens considerably at the temperature where burning skyscrapers break down 2014-02-14 12:25 which iirc is ~600..800°C 2014-02-14 12:26 for usual "normal2 steel 2014-02-14 12:27 a SF I once read however claimed that water has a number of additional unusual aggregate states under conditions like they are found on Saturn, some of those states making it the better material for building constructions than steel 2014-02-14 12:28 pcercuei_ has joined #qi-hardware 2014-02-14 12:28 DocScrutinizer05: that's true 2014-02-14 12:29 well, if your "buildings" will always stand in like 100k atm 2014-02-14 12:29 yep, that's been the idea of that SF, talking about buildings on saturn 2014-02-14 12:30 http://en.wikipedia.org/wiki/Ice#Phases 2014-02-14 12:31 Ice XIAn orthorhombic, low-temperature equilibrium form of hexagonal ice.

2014-02-14 22:57 DocScrutinizer05: sorry, what 2014-02-14 22:57 whats cameo? 2014-02-14 22:57 roh: projects.qi-hardware.com/index.php/p/cae-tools/source/tree/master/cameo 2014-02-14 22:57 ah. really ungoogleable 2014-02-14 22:58 yeah, it's too common a word :) 2014-02-14 22:58 what does it do?

2014-02-14 23:02 in ME you need to make such adjustments quite a lot. so you don't want to tweak every little thing. 2014-02-14 23:03 hmm? 2014-02-14 23:03 #s/want to/want to have to/ 2014-02-14 23:03 I don't get it 2014-02-14 23:04 let's say you have 256 BGA balls. so you entered each of them, with some radius value. then you find out you have to make them smaller/larger. how do you do that ? 2014-02-14 23:04 dumb cad (qcad and friends): you go to each of the 256 balls and edit the radius. smart cad (fped): you edit the radius value you defined somewhere. 2014-02-14 23:05 of course, in fped you also have loop constructs and the like 2014-02-14 23:05 I think freecad may work for 2d 2014-02-14 23:05 I mean, you could just stop at the "sketch" step 2014-02-14 23:05 maybe even extrude it to the thickness of your material if you like 2014-02-14 23:05 this explains the loops: http://downloads.qi-hardware.com/people/werner/fped/gui.html 2014-02-14 23:06 yes, freecad may be a possibility. it may get hard to follow the logical structure but it has good features 2014-02-14 23:06 I just wish it crashed less often 2014-02-14 23:06 wpwrak: I'd probably select all of those bga pads, then select "Size and Position" from context menu, and edit "radius" 2014-02-14 23:06 (well, it didn't quite work back when i tried it but it looked encouraging) 2014-02-14 23:06 ah, so it still does that ... 2014-02-14 23:06 it worked well for me, if you can tolerate occasional crashes 2014-02-14 23:07 perhaps it's easiest to just get gdb and fix that. 2014-02-14 23:07 DocScrutinizer05: heh, okay. let's make it some spacing then ;-) 2014-02-14 23:07 it asserts on something dumb like 0-vector where a 3-vector is expected. 2014-02-14 23:07 eh? 2014-02-14 23:08 like in "relative postion" ? 2014-02-14 23:08 DocScrutinizer05: let's say a cut-out for some connectors. let's assume you have lots of them. you work with, say, 20 mm. but then you notice it doesn't fit. so you increase to 20.5 mm. welcome to tweaking all the coordinates :) 2014-02-14 23:08 yes 2014-02-14 23:09 umm, while your example doesn't work, I think i know what you meant 2014-02-14 23:10 and fped also has automated measurements. so it shows you immediately what dimensions you ended up with. rather convenient when comparing footprints with data sheet drawings. 2014-02-14 23:24 lekernel has quit [Quit: Leaving] 2014-02-14 23:42 http://en.qi-hardware.com/wiki/IEEE_OUI_assignments ...
