When I saw on PCBShopper, a PCB fab price comparison site, that Elecrow was having a EOFY sale of USD0.99 for up to ten 100x100 mm boards, shipping extra, I decided to sample their service. (This sale, until 23/06/2019, appears to be available to all, not just new signups, but can only be availed of once.)
First of all I should mention that my project is not demanding at all, it uses THT components on a 0.1 inch pitch grid. It does however have quite a few chips, and 66 nets.
This time I sent in my first design using Kicad (eeschema, pcbnew and freeRouting). I had already debugged the circuit on a breadboard and also double checked using the Design Rule Checker (DRC) and the very useful Highlight Net feature of pcbnew. The latter is the desktop equivalent of doing a continuity check on the wires in the schematic, and will guard you from rookie errors like forgetting to connect the (invisible) power pins of a component.
Elecrow's PCB order page has the usual selection of options. I took the cheapest options which were all I needed. You also specify a Gerber package (zip or rar) there. I didn't find a link to a Gerber viewer but there are many online viewers elsewhere. There is an instruction page explaining how to order, and the technical parameters. As soon as you have entered all the parameters and uploaded a Gerber file, you will be asked to pay, by credit card or PayPal. This is in contrast to my previous fab (PCBWay) where it underwent checking by a staff member before I was emailed to start the job by paying.
After I had paid, I received email thanking me for my order. After a while my account page showed the order In Production. No other feedback. I supposed this was good and meant that my job had passed the design rule checks, but can be disconcerting if you were expecting some feedback.
My job stayed In Production for a week, even though such jobs normally take only 2 days. There was no progress display. It's possible that they assigned jobs from the offer a low priority. Elecrow is not just a fab but also do assembly, and make modules. For $1, I can't complain. So I just busied myself with other stuff.
A week later, I got an email saying that my order had shipped, with an attached photo of the package just before insertion into a parcel bag.
I had taken the cheapest postage option, PLT Express, (did I already mention I'm cheap? 😀) so I was prepared for a long wait. But I was surprised a week later when I was notified that the package had cleared customs and would be delivered in a day or two. And so it was. From submission to receipt was just over 2 weeks, a nice surprise. It turns out that PLT Express is run by DHL. I wonder why if Elecrow can get the service that cheap, the other fabs don't use this service. Postage charges may be different for other countries.
The package was a sealed bubble wrap one, and contained 11 boards, 1 spare just in case. (Wonder if one would get 6 if one ordered 5?)
So how is the quality of the boards? The front copper side:

I have absolutely no issues with their work, they did a good job and merit the review stars they have on the PCBShopper site. It's just that their customer facing site is not so polished. I'll post another photo when I have assembled one board and got the circuit working.
