The solder layer is distinguished from the paste layer

Foreword: Many projects do not know the solder mask and the soldering layer. It is to open the window, but only the paste layer, there is no solder layer, some board factories do not look at the paste layer (note that this is used) Open the steel mesh), so [...]
