Re: gEDA-user: Automatically start wire placement when you press the hotkey?
So is there a solution to this? Anybody get the wire key to work on key press rather than on click?

gEDA-user: Automatically start wire placement when you press the hotkey?
I had to redo my linux box so I installed a fresh copy of gschem from git and it seems like the method of wire placement has changed. When i press the wire hotkey, I have to click somewhere on the schematic before I can start drawing the wire. how do I change it so the wire placement starts at the cursor when I press the wire hotkey? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: Linux Desktop für gEDA
Do you guys use your linux box for general desktop usage or only EDA? I ask because I have tried many times to make the switch to linux for general desktop usage but can't get over the inconvenience of it. I have a linux box specifically for EDA (gschem, pcb, spice simulations, etc), so I couldn't care less what the WM is. It could be motif for all I care.

Alright guys I think I need a bit of help with the costs. 4pcb is expensive. I have around 80 or so SMD (mostly 0805's and some IC's) and the quote feature they have on their website is quoting me ~$20 per board at a volume of 50.

gEDA-user: info on pcbinternational chinese boards
I forgot who it was but someone asked me on the quality of these boards, so here it goes I ordered 50 qty, $4.95 each, and the basic summary is, with everything in life, "you get what you pay for" Now, with that said, electrically, I couldn't find anything wrong with these boards, but I have only assembled a few so far. The hole size/placement however, is a little suspect. I have some throughhole parts that are a "snug" fit, but with 4pcb boards, they are just that, "snug". The boards that were delivered by pcbinternational I think got some of the hole sizes just slightly off where I had to kind of press fit some parts. Yes I got them in, but they were a little past "snug". Another area they went cheap on is the soldermask, this probably bothers me more than the hole size issues. The soldermask is very noticeably thin compared to 4pcb boards. It just looks kinda "cheap" for lack of a better term. After reflowing some SMDs, apply flux remover, and brushing, some of the soldermask came off the routings. I was brushing hard, but I can brush hard on 4pcb boards and the soldermask will never come off now matter what because it's so thick. I just have to be more careful with these chinese boards. All and all, these board are "okay" for a production run, but you can definitely tell where they are skimping on the cost. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Board cleaner recommendations
After you get done soldering and fluxing up your board to solder a lot of SMT components, what do you guys use to get it looking flux-free and clean again? I tried MG Chemical flux remove and while it does remove the flux, after washing it (with tap water) and drying it, it leaves a nasty well-ish film on the board that make it actually look worse. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Re: gEDA-user: inexpensive 2-layer pcb prototypes in 2 weeks? 3 weeks? 4 weeks?
I don't know what your profit margins will be like but even if you have a design flaw in the first board the spending another $132 sucks but IMHO shouldn't make or break whether you profit or not given a 150 board run. On my previous project I broke even only selling 6 boards (prototype that was 100% functional - I got lucky). Anyway my point was I don't think $33 is that bad for a low volume run especially since advanced circuits fabs very high quality boards. And no, i don't work for advanced circuits. In fact for my production run I'm using a chinese company.

The board size is 6.275x1.705. Modest amount of holes/vias, nothing too crazy. Tolerances are standard, I think the default setup in pcb. Shipping to the US, specifically CA.

gEDA-user: cheapest pcb manufacturer that does silkscreen/soldermask
Hi all, I have been using 4pcb for awhile now and even for a small board the cheapest option they have is $250 for an order of 5 boards (their minimum quantity). They have a bare bones (no silk/mask) option that I have been using that allows you to order 2 for $60 which is a great option most of the time. I have order their silk/mask board for $250 a few times and their quality is superb however I'm looking for something cheaper and perhaps has a lower minimum (maybe 2). I'm willing to deal with a lead time of up to 2 weeks. Any suggestions? ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
