Select “Top” in the “Objects” field, checkboxes are everywhere, except for “holes” and “dimensions”, export a file called Top. There are no complaints about metallized transitions either. Fill in the rest of the fields and confirm. So, after tracing in DipTrace, we need to export the result to the Gerber file format. Now a photo of the finished work: Similarly, we export the "Bottom" with the name Bottom. Somehow I wanted to repeat one of the projects found on the Internet, so much so that there were about a dozen friends who wanted to buy the finished product. The trails are well laid out.

We see the window
Basic ordering items We leave everything as in the picture Since I have a two-layer PP, we export the "Bottom Marking" in the same way and save the file with the name Bottom_silk. After placing an order, your project will be audited for specification errors and correctness. To complete the project, you need to make a printed circuit board (hereinafter referred to as PCB), engage in LUT for such an industrial scale – for me this is the height of masochism, and I wanted factory beauty.
Here is what they sent me.
Next, click “Upload PCB File, Place Order”
Select "Apertures", press "Auto" and close the window. Next, export the borders, select "Board Borders", export with the name Border.

Click "Export" and save the file with the name Top_mask, similarly export the bottom mask with the name Bottom_mask. The width of the tracks is from 0.3 mm to 0.5 mm with a distance between the tracks of 0.2 mm (there was no point in shrinking). Dimension: PP size in cm Hurrah! We’re almost done. The silkscreen is smooth, everything is in its place. Let `s start?! There was a tightly sealed package, which was already packed in a pimply film and placed in an ordinary cardboard box, rewound with tape. Flying probe test: Here you can select Free for sample test We see the window We press "Export" and save the file with the name Top_silk.
The last item remains, you need to export a file with a description of the coordinates and diameters of all the holes on the board. Layer: Number of layers For example, I filled in the fields, after the calculation we see the cost of work, the cost of delivery and its options, and the performance characteristics of the order. To do this, “File-Export-NC/Drill…” Next, select the "Top Marking" item, where "Objects" are indicated, leave the checkboxes by default. A nice bonus was that 11 boards came instead of 10. I already see problem areas where I could do better. Apparently they cut from one blank, everything that fit was done. Everything. exported files in one folder are saved in the rar archive.

This is my first review, please do not swear strongly, I will take into account constructive criticism.
Upload Files: upload the archive of the previously prepared PCB project. There are no living creatures at home, so as a bonus there will be Now we are ready to order PP on the site Go to the Online Price Calculator. Further, how the mail will work, I waited about three weeks. Please pay attention, we do not put the "Mirror" checkbox anywhere. Letter Color: Silkscreen color Photo "unpacking", unfortunately, did not. I rate the quality at 4 .

Press the “Auto” button, then “Export” the file named Drill No manufacturing errors were found. I ordered a two-layer PP 65×60 mm in the amount of 10 pcs. You can also click the "Preview" button and make sure that all the top markings are in place. To prepare the software, I chose my favorite CAD program DipTrace. Transition holes: inner diameter 0.5 mm, outer diameter 1 mm. I want to tell you how and where I ordered boards in China, as well as how to prepare a project on my own and what to look for.
