mbeals 74 Posted March 18, 2014 Author Share Posted March 18, 2014 I reckon the legs are worth the extra effort if you need to do any debugging yes and no. The extra holes required for the legs make it impossible to route traces to all the pads and stay within the specs supported by the low cost board houses (you have to use 6 mil traces and be <15mil from the drills). I've also found that the legs are really stiff and difficult to get to [dis]engage without the help of needle nose...and they require you leave enough space surrounding the pad to get your fingers/tool on the cable to get it free. As an alternative, there is this guy: http://www.tag-connect.com/TC2030-CLIP which secures the no-legs cable to the board from behind, eliminating the hassle of the legs. I haven't used it yet, but it appears to be a better solution (at least for what I do). Fred 1 Quote Link to post Share on other sites

I noticed the spacing issues too, although I managed to get it to work on my board with 0.2mm traces (7.8mils) without tripping the DRC. I'll see soon how the legs are... hoping it's workable 'cause the board I have in mind won't have that much room behind it for fitting a pair of needle-nose. Quote Link to post Share on other sites
Fred 453 Posted March 18, 2014 Share Posted March 18, 2014 Interesting. I haven't gone below 12mil traces yet, but I should be able to do 8 without a problem. Happy to see what issues there are with legs on a home made board. I suppose worst case is that they could be removed. @greeeg might be onto something with his clothes peg!

Fwiw, I did home-etching with 7 mils once, that's about as far as I'd take it... (it wasn't 100% success rate either, but I was fitting it between two pads) Quote Link to post Share on other sites

Fred 453 Posted March 18, 2014 Share Posted March 18, 2014 As the 43oh standard seems to be settling on 6 pin and I've been advised against legs, I'd be more than happy to go with the same TC2030-MCP-NL as mBeals and Spirilis. I've got an idea which may overlap with this, but I'll post about it separately. Quote Link to post Share on other sites
mbeals 74 Posted March 18, 2014 Author Share Posted March 18, 2014 I really don't NEED another cable (or the clip). I already have a legged version. I'm also finishing up another project at the moment, so I don't have anything in the works that would need it. Quote Link to post Share on other sites
spirilis 1,265 Posted March 19, 2014 Share Posted March 19, 2014 @@bluehash Sure you can take off the TC2050-IDC-NL request for me. I think 6 pins should be plenty for MSP430 work. Quote Link to post Share on other sites

Fred 453 Posted April 24, 2014 Share Posted April 24, 2014 I'm just adding some pin headers to my current project. Did anything ever happened about these? Quote Link to post Share on other sites
