PCB layer naming

A few single layer or multi layer(>=4) PCB board, Please provide a clear layer naming and order list. Otherwise, the result is may error.

For single layer PCB board, As in the following examples:

As in the above description, We can understand it and no opportunity to make mistakes. These are just our recommendations, but do not apply to all file of single PCB board.

In a few cases, such as all the file with the same suffix (eg: *.txt, *.gbr, *.pho), We can not accurately identify and determine the sort of PCB layers, It had to delay the order processing time.
(This means that we do not know which layer is the top layer, inner layer 1, inner 2, bottom layer and so on.)

All multi layer (>=4 layer) naming, Please provide a clear layer naming and order list to us (such as text,pdf or in the gerber file).

Some simple ways, such as using the number "1", "2"... or letter "t","b","bot","top" ... fill to in the coppoer layer or renaming the names of all layers.

such as xxx_top.txt, xxx_sil.txt, xxx_inner1.xxx, xxx_in1.xxx, xxx_in2.xxx, xxxbot.txt and so on. (If we can clearly identify the order of layers, doing so is not necessary)

Note: Please remove the extra characters and describe. Or, if possible, removing unwanted silkscreen layer file. By default, all silkscreen layer will be processed.

The end result is to save your time and reduce potential errors.

If gerber file from the software as protel, powerPCB, eagle, proteus, cadence, orcad etc. please do not worry the layer naming.

For example, some known definition of layer name as follows:

*.GTL, *.GBL,*.TOP, *.BOT: copper layer
*.GTO, *.GBO,*.SST, *.SSB: silkscreen layer
*.SPT, *.SPB: solder paste top,solder paste bottom
*.SMT, *.SMB: soler masd top, soler masd bottom
...
