Re: [PEDA] Vias do not tent when expected
Hi Leo, I just confirmed everything you described. Auto placed vias follow the via solder mask expansion rule. The default tenting attribute is ignored. Manually placed vias have the default attributes including tenting.

At 08:40 PM 3/4/2004, Leo Potjewijd wrote: All the vias that are placed during interactive routing (switching layers) show the big expansion , all the vias that are placed with the Place Via command are tented. From all the discussion which has preceded, this is exactly expected behavior. The Default Via is set to Tent, and the default only controls manual placement of vias. Autorouting and Route Interactive use a via specification from design rules (Routing Via Style). In the design rules, one controls tenting by creating a negative solder mask expansion (Manufacturing/Solder Mask Expansion/Via Specification). An alternate method to use, particularly if one wants to tent some vias and not others, is to convert all or some vias to free pads; the pad name can then be used to control whether tenting happens or not. *** WARNING : rant coming up *** Because Protel99SE.exe has caused errors and will be closed. My condolences. [...] The weirdest part by far of all of this is that I did NOT EVER have a P99SE crash at home (the via problem _is_ present at the home system too). Just to repeat, there isn't really a via problem, rather a misunderstanding of how the Default works and how tenting is controlled. Autorouted and Route Interactive-created vias do *not* follow the Default settings. That system (P2 @ 910 MHz) is running the _same_ W2kPro and P99SEsp6 (and loads of other stuff that doesn't run at work) on the _same_ amount of memory (768 MB). No network though, and a different virus scanner (Norman at home vs McAfee at work; both set to leave .Ddb files alone)... Right now, I'm in for some _very_ drastic measures. Any hints? First of all, the virus scanner and network differences are not likely to be the cause, in my opinion. Rather the most likely causes, at least the ones I'd first suspect, are the video card or a memory problem, i.e., a bad chip. There are video cards known to cause Protel to crash ATI cards were famous for this. And a bad memory can cause, of course, all kinds of problems. Sometimes they will only show up with one program that happens to be vulnerable. As far as the bad memory possibility is concerned, I'd swap around memory devices, if possible, or at least run some very thorough memory test utilities, the kind that you let run all night It is always possible, as well, that a particular installation has gotten trashed in some way, so reinstalling may be in order. Remember, when reinstalling Protel, to delete the *99SE* files in the System folder.

Re: [PEDA] Vias do not tent when expected
see my earlier response on this the via chekcbox takes precedence which i think is logical since you are at the most specific level only by having this ability can you easily make exceptions to the design rule without a NO DRC i for one would hate to wade through a DRC about this exception, but i see your point that there may be stuff going on without one's specific awareness i always thought that soldermask expansion belonged better as a property of the pad or via than as a design rule but at this point, whatever re the default primitive settings as in this example there is one more point that may need clarification and which may be at the root of the original post the 'default' setting applied in Tool Prefs Defaults ONLY applies when using the Place Via command if instead you are manually routing a board and the * key when changing layers then the via in the Via routing style is used and it does not carry the tenting attribute even if it matches the size hole of the default via Dennis Saputelli Abd ulRahman Lomax wrote: At 07:34 AM 3/4/2004, Leo Potjewijd wrote: I like my vias tented so I keep the tenting checkbox in the default via settings dialog checked. While interactively routing a PCB I noticed that the automatically placed vias did not get tented (and the forementioned checkbox is still checked) This discussion has gone back and forth a few times, yet some basic facts about the situation I found less than clear. There was an ambiguity about what was written. The aforementioned checkbox is the checkbox in the default via settings dialog. That is a setting which will control the configuration of vias manually placed while that setting is active. It does not affect vias that are already placed, nor will it necessarily affect what the autorouter places. (You might expect it to, but Protel is put together from various programs that do not always function together with complete rationality. The 99SE autorouter, in particular, is its own creature and I'm not surprised to find that it does not respect in any way the default settings, just as the default settings may be altered whenever you edit a primitive as it is being placed. The default settings dialog is a convenience of occasional use, not an absolute control. What I'm saying is that if the autorouter places vias which do not have the tenting checkbox checked, it is no big surprise once one is familiar with how 99SE works. Historically, tenting was controlled only by design rule, the tenting attribute was one of the latest things added in the Protel 99 release, as I recall. It's a convenience. It's not particularly one that we requested, since using design rules to control tenting was already quite sufficient. If there is a conflict between a design rule and the tenting checkbox, I'd place my bets on the design rule, given the history of the program. Which one is paramount? I don't know, and I'm not particularly motivated at the moment to go and test. I never check that tenting checkbox, precisely because I don't know the answer to the question. I do know that if the checkbox is unchecked and the design rule says tent, it will be tented. That's enough for me. Because the design rules are explicit and their scope can be readily determined (this gets even better in DXP), it is better design practice to control tenting through design rule than through a primitive attribute manually (or supposedly by default) assigned to each via. If somehow that checkbox got unchecked, how would you notice it? Suppose you have vias of a certain size and you want to tent some and not others? The checkbox does make a way for you to do this, but there is a better way, and that is to convert the vias to pads, give the pads a distinctive name (say TENTED for the ones you want tented), and create a pad-scope design rule for Free-TENTED. Vias are basically free pads with the restriction that they are only round and do not have names. If you want to distinguish some of these vias from others, it is better to select them and convert them to free pads (with Tools/Convert); then -- they will still be selected -- you can globally edit them to give them a distinguishing name. I do not want to end up with a board that has some vias tented and some not, and the global edit on the complete board afterwards is too easiliy forgotten. Yes. Precisely. That's why the design rule approach is better. They (the autoplaced vias) did, too Seems the rule takes precedence over the default setting. The basic error here is in assuming that the default settings. I can easily understand why one would make the assumption. *The default settings are a convenience to speed up manual design, they don't control anything.* What I don't know, it's an interesting question, is what happens if a design rule for tenting is in conflict with the checkbox on an individual via. I dislike ambiguities like
