My first prototype design just came back and basically my design has been plonked in the middle of a Eurocard sized PCB. However, all I want is a double sided board and it's all leaded components - no SMT. The board edges are not important as it is mounted on pillars and the holes for that are on the PCB. A quick hacksaw job and I am ready to populate. I got over not having a silk screen by labelling important parts in copper. Overall I am very pleased. Cost me nothing and took about a week. I have another similar sized board I will be sending off in the next few days. I'll certainly let them quote for the production version. Cheers Ian |
