gEDA-user: SFlags definition question
Hello All, Sorry to bother you again with a novice question. I'm in the proces of understanding PCB so please be gentle. I have a component (DPAK) on the top (component) side of my pcb, surrounded by a polygon. I have connected one pad to the polygon by using copper trackes. I also have a polygon on the bottom (solder) side of my pcb, right beneath the one on top. I have connected the two polygons through via's with a solid connection to the plane (polygon). Now I want to free the via's of any soldermask on both sides of the pcb. So I press the K key until the clearance is OK. So far so good. Now my question: I like to fully understand how PCB works so I look in the .pcb file with a text editor and found. Via[312000 28 4000 2000 0 2000 selected,thermal(3S)] and Via[302000 261000 4000 2000 4000 2000 selected,thermal(0S,3S)] I understand that the first one has no clearance and the second one has. Question 1: is the clearance valid for both sides of the pcb? Question 2: In the documentation (pcb.pdf generated during installation) I find in section 8.8.28 Via that the last argument is an SFlags. In F.1.76 SetThermal I find that Style = 3 means a solid connection. So I do not understand what thermal(3--S--) means or (0S,3S). Can anyone help me? Where can I find this kind of information (e.g. definition of SFlags)? I hope you can help, thanks.

Besides that I am a bit of a control freak and I really like to know what's what in my designs. On the other hand I understand that you developers do not have the time to explain every small detain to every novice that comes along claiming he wants to become a developer. But if the PCB project needs more developers they need to be grown (I read that here on the list some time ago ;-), not that I claim to be developer material but I like to understand PCB as much as possible and maybe how knows..some day..

Some tips for easier DRC problem identification: Select the silk layer as your active layer (required for the next step), then de-select all the copper layers and run the DRC. Clicking on a violation will re-enable affected layers, so the objects in question are _much_ easier to identify. De-select all layers before moving onto the next violation.

Re: gEDA-user: (Solved) SFlags definition question
I don't fully understand the source code and I don't know if anyone is interested but this is what I found. Apparently there are 5 types of thermals: 1. a X shape with straight spokes 2. a X shape with round spokes 3. a + shape with straight spokes 4. a + shape with round spokes 5. a solid shape In the PCB file they are represented by: 1. a nothing 2. a X 3. a + 4. a t 5. a S The thermal SFlags attribute follows the structure: thermal(layer[spoketype],layer[spoketype],layer[spoketype]) So: Via[10 10 5500 2000 0 3000 thermal(0X)] is a via with a X shape thermal with straight spokes connected to layer 0. Via[10 10 5500 2000 0 3000 thermal(1t)] is a via with a + shape thermal with round spokes connected to layer 1. Via[10 10 5500 2000 0 3000 thermal(0S,1-3+,4)] is a via with: a solid thermal connected to layer 0, a + shape with straight spokes connected to layers 1 through 3, a X shape with straight spokes connected to layer 4 Thanks everyone.

Blindly ignoring violations is probably not a good idea. Better to understand them first. I hope you don't think I am picking on you, and maybe I am mis-reading the design, but I think there's a bunch of stuff wrong: 1. You have silkscreen printing going right through most of your pads. How do you plan to solder to that? 2. Many of your parts are placed *extremely* close together. Certainly a pick and place machine won't be able to handle it. Hand placing may be difficult. I'm not sure if you'll be able to solder to them. 3. On the signal layer, you have a big copper ring going along the perimeter, unconnected to anything. That is not a good idea. Maybe you intended this to be a ground guard ring? If so, it should connect to ground. There's more.
