For my previous projects, I have been using iTead for my PCB’s. This time I wanted to try out dirtypcbs instead, and so far the service have been amazing.
Comparing to the only other PCB service I have used so far, the handling time seems pretty similar.

However, with dirtypcb, all board colors are the same price. So if you just want plain green, iTead is cheapest, but if you want any other color, dirtypcb is cheapest.
This chart is for 2 layer boards only. Also notice, iTead got a 5x10cm option, which dirtypcb does not.
|5×5 green||10×10 green||5×5 colored||10×10 colored|
Another thing worth considering, is how much you can fit within the allowed size. When ordering from iTead, you are allowed panelization, but you are only allowed to seperate them by a line on the silk screen, and board outline should go all the way around the edge of the PCB’s. With dirtypcb, you are allowed to do some pretty crazy panelization, just do a google search and have a look at what people already got made.
Yes, exclamation mark and lots of yelling!
The PCB’s has arrived, lets have a look at them.
At first glance they look very good, silk screen is fine, both on top and bottom. The outline of the board feels smooth with a sharp edge, just as it should be.
Let’s have a closer look.
Even close up, the silkscreen looks fine, this text is only set to 0.8 in Eagle, with 8% ratio and vector font.
When looking at the alignment of the different layers, you can see they are a bit off. On the bigger pads it isn’t a problem, but on the smaller ones it is very close to the edge of the holes, same can be seen on the via’s. Still, with the layers a bit offset to each other, it changes nothing of it’s function. And considering the price, it really isn’t that bad.
Time to put some parts on!
First some SMD components, hand soldered with a soldering iron, so the soldering isn’t that good looking…
And with almost all components on. So close!
After putting the 2×4 header in, I could put the ESP8266-01 module in, connect the DHT22 sensor, and test it out for the first time…
And it works! Currently logging temperature and humidity to https://thingspeak.com/channels/34146
