RobG 1,892 Posted February 4, 2013 Share Posted February 4, 2013 I just got a message from Elecrow that they will be trying to figure out the problem with black paint. Just to be clear, this is mostly cosmetic than anything else. I hardly see any copper exposed, so there should be no issues when soldering. BTW, I didn't tell them about this problem, they took proactive step, great service again. Also, I got my boards from Elecrow in 2 weeks!!! I am still waiting for my boards from Seeed that were ordered 3 weeks ago (and I looks like I will have to wait another week.) Quote Link to post Share on other sites
roadrunner84 466 Posted February 4, 2013 Share Posted February 4, 2013 What do you mean when you say barely any copper is exposed? Dit they use a solder finish? Don't they offer ENIG or HASL which goes also on the tracks before the paint is applied? How are the vias done? they need to be plated in some way from the inside, just plain copper, or solder finished as well? Quote Link to post Share on other sites

Just wondering how those turned out. Quote Link to post Share on other sites
RobG 1,892 Posted February 4, 2013 Share Posted February 4, 2013 I am getting a set of black and red boards, it was shipped on 2/1, but I don't have tracking # yet. I hope HK post is not celebrating already I think B3 will be getting his red boards any day now too. Quote Link to post Share on other sites
TheDirty 33 Posted February 5, 2013 Share Posted February 5, 2013 I got black boards from Seed or iTead, I don't remember which and they came out fine. Quote Link to post Share on other sites
yyrkoon 250 Posted February 9, 2013 Share Posted February 9, 2013 Ours will possibly be here next week sometime. they shipped out of HK today( technically yesterday ). The pictures they sent looked nice. Green PCBs. Quote Link to post Share on other sites
RobG 1,892 Posted February 21, 2013 Share Posted February 21, 2013 I got my red boards from Elecrow and they are beautiful! The only thing is minor misalignement of large holes (for 0.1" headers.) Each hole is in different place, so it looks like loose drill or something. Not a problem for me, headers fit nicely and this is only visible with magnifying glass. All small holes (vias) are perfect. Also tried the thinnest board they have, 0.6mm, awesome! Will definitely order that thickness again. Quote Link to post Share on other sites
cubeberg 540 Posted February 22, 2013 Author Share Posted February 22, 2013 Also tried the thinnest board they have, 0.6mm, awesome! Will definitely order that thickness again. Wow - I did some 0.8 boards for my wearable board - they were crazy thin. Is the 0.6 so thin it's flexible? 0.8 was pretty bendy as well. **Edit** - Good to know the red came out well. I've got a couple of boards almost ready to send out (wanted to batch up a couple of designs). I'm probably going to try a red and a blue board Quote Link to post Share on other sites
RobG 1,892 Posted February 22, 2013 Share Posted February 22, 2013 0.6mm is bendy, but not flexible. cubeberg 1 Quote Link to post Share on other sites
username 198 Posted February 24, 2013 Share Posted February 24, 2013 0.6mm is bendy, but not flexible. Hmmm.... not a fan. Unless you have a super good need for 0.6mm, its usually not worth the risk. Smaller the thickness the more likley the board will warp under heat. Doesn't take much of a warp to screw over any 0.5mm pitch parts. I suppose if your hand soldering everything it doesn't matter to much but beware if your using a oven. All small holes (vias) are perfect. Nice! How small did you go?

cubeberg 540 Posted February 26, 2013 Author Share Posted February 26, 2013 Just placed an order for 4 sets of boards - three blue and one white. We'll see how the white turns out. Quote Link to post Share on other sites
RobG 1,892 Posted February 26, 2013 Share Posted February 26, 2013 Nice! How small did you go? 0.01968 & 0.02362 vias. Compared to Seeed, there's hardly any difference. Also, Elecrow's support is excellent. There was a little mixup which didn't cause me any inconvenience or delay, and I got a second set of boards for free! Quote Link to post Share on other sites
yyrkoon 250 Posted February 28, 2013 Share Posted February 28, 2013 We got 6-7 different boards made from these guys, and they all seem great. Quote Link to post Share on other sites
spirilis 1,265 Posted February 28, 2013 Share Posted February 28, 2013 Just got my boards... 2 cents- The vias were all tented, a little weird b/c I don't recall unchecking the vias box in the soldermask layers. Seeed and OSHpark never tent them. Not a problem, just minor point to note. The drill holes are indeed slightly offset or something. Probably not an issue, I'll see once I assemble a couple. They gave me exactly 10 boards, Seeed always seems to toss in 1 or 2 extra. Not a big deal, Elecrow is cheaper anyhow! The red color is very nice, looks closer to the TI LaunchPad board's red color than Seeed's slightly orange-ish red. A couple PTH holes had some greenish-yellow specks of crud in them, but it wiped away (and there was HASL solder underneath so it's not like a corroded un-HASL'd pad or anything). (my faulty 1st edition F5172 board up above, with Seeed's orange-ish red color for comparison sake) username and bluehash 2 Quote Link to post Share on other sites
