The PCB color generally refers to the oil color on the board that is most intuitively seen when you get a PCB board and is primarily determined by the color of the solder mask or solder resist applied to the surface of the board. The solder mask acts as a protective layer that covers t...
in semiconductor fabrication. LPSM can be silkscreened like an epoxy, or it can be sprayed over the surface, which is often a cheaper application method. The more advanced (and accurate) method is to use a lithography process to define solder mask openings for pads, vias, and mounting ...
I am using VX.1.2 pads layout and am trying to have a solder mask that has thermal tented vias under the heat slug for helping for cooling. I didn't originally and the solder would just get sucked through the vias causing a pour connection to the thermal pad under the chip. Thoughts ...
checking paste and solder mask I would like a report or something that would tell me a pad has missing mask or paste. Exist? Trying to use the colors doesn't seem to work as the copper color just dominates. It would nice if the paste... Test points and...
The solder mask is automatically generated for Gerber plot production from the pad information. You need to add the layer if you wish to do any editing within DesignSpark PCB. With the solder mask layer enabled you will be able add to shapes layer
In the picture below, the layer stackup has been fully completed. Additional layers have been added, including silkscreen, solder paste, and solder mask. Also, layer names, functions, and widths have been added, as well as fine-tuning for the board materials and dielectric constants. Now tha...
Add SoldermaskIf you want to add soldermask to sections of your board, just make the Soldermask Top or Soldermask Bottom layers active and use the Place » Shape utility to simply place any object that will represent soldermask (where copper will be exposed).Delete or Modify Soldermask...
More than 99% of the circuit boards employe green solder mask, so the solder mask refers to "green" most of the time. Of course, there are also red, black, blue, white, etc, which are used in different applications. For example, at the NPI stage, some RDs specifically use red to ...
The solder mask dams are needed between the SMT pads due to the fact that it serves as the isolation wall, which prevents spillovers.In general, the minimum size of the dam should be about 0.004 inches. For through-hole components, use the appropriate lead lengths. ...
