these boards, but I have only assembled a few so far.
. . The boards that were delivered by pcbinternational I think got
some of the hole sizes just slightly off where I had to kind of press fit some parts. Yes I got them in, but they were a little past "snug".
. . It just looks kinda "cheap"
for lack of a better term. After reflowing some SMDs, apply flux remover, and brushing, some of the soldermask came off the routings.
Thanks for that review. I just got my first look at some boards by myropcb.com that are very good looking. The plated through holes are all concentric with their pads and mirror reflective inside with no excess of solder, ( the board is HASL finished except for edge connectors. The routing around the perimeter turned out nicely and accurate as tested against connectors and moldings for both boards I had done. http://ecosensory.com/tek/tek_tm_flex-prototype-sm.gif http://ecosensory.com/tek/tek_tm_flex-prototype-2-sm.gif http://ecosensory.com/tek/tek_7k_flex-prototype-1-sm.gif Dealing with myropcb.com was via email only and the communication was poor with 4 to 24 hour delays and partial answers to questions. The price was hard to figure for my routed boards and they want to charge you one at a time for prototypes, but in the end it comes down to $17 per unique board qty one, plus $35 shipping for the first one to USA, and $15 shipping for remaining boards. I got two different prototypes made qty one each 2-layer, 2- silk, gold edge fingers, routed for $84 charged to my credit card. There was no cheap proto way to add a V-score, but that wasn't a big concern for protos, or if you get them to do a small run they will quote it in a setup charge. The board in the photos will be done qty 20 by them soon -- don't know the exact price yet, but from their calculator: qty 20 11.3 sq in boards in 7 days plus shipping time $150. --> .68/sq in qty 40 11.3 sq in boards in 7 days plus shipping time $189 --> .42/sq in qty 60 $216 -?-> .32/sq in +60 qty 180 $403. -?-> .20/sq in +60 John Griessen -- Ecosensory Austin TX _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
