1. Gerber Files Required:

The following files would be needed for the 2-layers PCB production:
Top layer: pcbname.GTL
Bottom layer: pcbname.GBL
Solder Stop Mask top: pcbname.GTS
Solder Stop Mask Bottom: pcbname.GBS
Silk Top: pcbname.GTO
Silk Bottom: pcbname.GBO
NC Drill: pcbname.TXT
Mechanical layer : pcbname.GML
Note:
  • The Gerber file must be RS-274x format, The format of the drill file can be Excellon
  • Board outline must be included at least in one layer if there isn't GML/GKO layer.
  • All the holes will be plated by default, if you need some holes not plated, please name the non-plated holes as pcb.name-NPTH.txt and leave a comment;
  • Please double check that the drill file is included in the gerber file. A lot of PCB order is delayed because of this problem.
  • For one layer PCB, If you need the solder mask on the top and bottom side, please select '1 layer PCB with solder mask both side' , don't select 2 layer to avoid delay.
  • For special requirement, please leave a comment when place the order online instead of only the readme.txt file. The PCB engineers only check the gerber file via software.

I have ordered about 30 different designs through Elecrow PCB prototyping and I have mostly positive things to say about the service and maybe a couple of recommendations.

Let's start with the service. It's pretty good really. The site works as intended, the order process is pretty easy, prices are reasonable. Turnaround is fairly fast. Typically I get a few more boards than in the order (10-20% more typically) which is nice icing on the cake. Shipping costs for orders over $300 is fast and most importantly free! This is awesome. You get to see a photo of your stuff before it gets shipped and that's a nice touch.

The quality of the produced PCBs is very good for prototypes. I have put silkscreen over vias, and really tiny fonts and they typically do get printed, and in most cases (not all) the text comes out legible and sharp. I have never had any issues with shorts or breaks in traces or vias. Sometimes the tinning on large pads is a little uneven, but should be fine with regular components. Other PCB fabrication places put their order ids on your board prototypes which is annoying. Elecrow keeps your board the way you designed it.

I had one issue with a board that had missing / flaked off solder mask and an exposed trace. This was one small (2mm?) spot on one trace on one board, out of hundreds of boards that I ordered. Overall quality is pretty good.

Prices are ok, with one exception. As long as your board is near (but under) the max size limit, you're ok. If your board is just over the limit and you have to go one step up in size, the price difference could be quite large. Unfortunately for me, most of my orders tend to be like that. Many other places that do prototypes allow you to pay by mm2, so no matter what, you end up paying for the exact size (surface area) of your design, and generally you end up paying less. Funny, because I initially switched to Elecrow for their prices, but now they're not as competitive as they used to be, and now I end up paying more here. I would really like to see per mm2 pricing, or maybe more choices for maximum sizes with smaller jumps to keep the prices competitive. I just don't understand why a 11x11cm board is 4-5x the price of a 10x10cm board.

Finally, it would be awesome to see an online gerber viewer after the gerber files are uploaded, and when reordering a batch. It can avoid costly mistakes and delays if you screw up packaging the zip file (not exactly trivial and happened to me once), or try to reorder the wrong thing.

Other than that, the service is very good. I intend to use it in the future and can recommend it to others. Hopefully Elecrow takes note of my recommendations and implements them in the future. I feel like it would greatly improve an already great service.

Outstanding customer support and service Review by Vince P

I am a U.S. based customer generally do not take time to write reviews. However, for this particular case I would like to share my experience with current and prospective Elecrow customers.

In the past, I have been using PCB services from local companies due to the requirement of high precision PCB manufacturing and the convenience of a faster local turnaround. I recently started a new project that was not necessarily time critical or high precision. Upon reading the positive reviews of other Elecrow customers, I decided to send my Gerber files to Elecrow in an effort to decrease prototyping cost and to test the waters a little with a different PCB manufacturing company.
I started with a small order of 10 boards with standard build time and 4 day shipping. To my surprise, I received an email from Elecrow 3 days later with shipping information along with an attached photo of the finished boards and I was skeptically awaiting the boards arrival to inspect the quality of the manufacture.
3 days later the boards arrived to me nicely packaged and secure. I was very impressed to see that the boards were extremely well manufactured and well above my expectations. I then decided to order a larger board with higher precision requirements and also upgraded to the 2 day service with express shipping. The new order arrived within 6 days to my office in the U.S. with perfect precision, silk screening, and component location placement.

Unlike many other customers here, I never received more boards than what was ordered but I am extremely pleased with all facets of the Elecrow operation and service and decided to use them exclusively for all of my future PCB builds.

Also worth noting is Elecrow's quality assurance practice. I was informed by an Elecrow engineer that I had a design flaw in one of my Gerber files which in turn, would have resulted in a batch of scrap boards. Thankfully, the process was halted before they started manufacturing the boards and I was able to fix the issues without loss of time or money.

If you are on the fence about trying Elecrow, I can fully recommend their service. Hopefully, you will receive the same great service and quality that I have been enjoying for the last few months. (Posted on 3/21/2017)

I have ordered many PCBs from Elecrow and every single one of them have arrived in a very timely manner with great quality. I have also received more PCBs than I have ordered which is a great bonus in my book. By far, this is one of the most cost effective companies out there. Thanks for the fantastic service.
