I’m getting a weird teardop/filled zone interaction that I haven’t been able to reproduce in a test project, it appears when I hit “B” to refill the zones but looks OK when I open the project. Just wondered if anyone had seen anything similar ?
Sorry, I haven’t tried, but I will comment on these “Bumps”. They don’t look very promising.
It looks like the zone has invaded the clearance. Doesn’t happen on the RST pad below.
Looking closer, the same problem on TDI pad. This seems to happen with two teardrops on the one pad.
It looks like the ‘teardrops’ are obeying the clearance rule and keeping out ? how can that be? I have never used them but are there many parameters that can even be changed within Kicad ?
It looks like those teardrops have thermal reliefs. I thought teardrops are made of similar constructs as zones and you could select them in KiCad V7 to examime their properties. (Them being zones explains whey can have Thermal reliefs, but still it’s probably a bug as the combination does not make sense to me). In KiCad V8, I can not seem to select teardrops at all, or with any other function then Schematic Editor / Edit / Edit Teardrops.
I guess it’s similar to clearances. You can set those too in multiple locations, and there are fixed rules to either inherit or overrule the settings from another “level”.
My opinion is that a teardrop to a pad and a thermal relief is not a valid combination. The only technical purpose of a teardrop is to strengthen the copper connection to the pad - useful for heavy components like transformers and switches
To give a little more background . . . this project started life in Solidworks PCB and is now in KiCad, I’m trying to clean it up as much as possible before I carry out some major redesign work.
When I update the PCB (F8) I get these warnings related to the teardrops, I’ve tried to go through and make sure all the Solidworks teardrops are removed but I still have these warnings and can’t figure out why (so far).
there are 18 warnings shown . . . I have more than 18 pads with teardrops so the warnings are not on all pads with teardrops.
My test project (which I can post) does not have any warnings.
