[kicad-users] Re: Data Base system integration
Greetings all, I am also new to Kicad and have struggled some with creating components. I have started using Kicad for designing professional PCBs as part of my consulting business and so far been quite impressed. Unfortunately for several reasons I am not sure that the professional world would be enthusiastic to using open libraries. First, there is some issue of trust. If you buy a CAD system, you know who is somewhat liable if you mess up a design. I'm not sure a vendor would really back you up either. But if you download a part from the web, then you either have to take your chances that it's right or spend time checking. So it may not be too much of a time saver. Second, companies might not want to put their libraries out there since it essentially shows what parts they are using and could potentially give away their current designs. If there was a way to anonymously put parts online then that would be ok. Another point of contention is something the group I work with recently discussed. Several of us like to create our schematic symbols to look like the physical part, myself included. I think this allows me to build a schematic that then translates better into a PCB. You don't end up with a ratsnest of traces crossing each other that looked pretty on the schematic. Others like a functional schematic symbol. One of my coworkers goes this way and will split parts such as putting the memory/data bus of a micro as one section of the part, some of the ports as another section, more ports in another section, and the power on yet another section. His schematics seem to put different sections on different pages. He tried Kicad briefly and gave up when he ran into trouble making a very large multi section part. Of course, if we can persuade component manufacturers to create libraries and put them out there in the libraries, that would be wonderful. I do really hope that Kicad can continue to evolve and become a greater force in the professional world. The group I am working with has no standardization and different workers use Orcad, Eagle, gEDA, and Kicad.

[kicad-users] Re: Data Base system integration
I forgot to mention another point that I had been thinking about. I stopped using "generic" library parts about 14 years ago. What I mean is, I no longer select R as a part, then fill it in on the schematic. I create separate parts for each value, size, or whatever parameter. Then I select a part based on exactly what it will be, such as my 12K_5%_0402 below. Kicad makes this very easy since you can edit the library in a text editor and just change the values. I built up all values of 5% 0402 resistors this way and then spend no more time filling in values. This also lets me have the library contain the part numbers from 1 or more distributors so they get output into the bill of materials without further typing. In the case of Kicad, this also means I don't have to associate a component to module for these parts. In any case, this was another possible reason why a common library might not be acceptable since most users would not want to buy from the same distributors. Just my thoughts...

[kicad-users] imported components
Hi Just finished a double sided PCB with SMD components. Just a word of warning. I used a few components imported from the Eagle libraries. The through hole components did not have the solder mask enabled on the copper side, it could have been a problem if my PCB manufacturer had not noticed it. Cheers Darryl
