Paste Mask Layer is used to make the stencil with punching holes, and the holes in the stencil correspond to the solder joints of the SMD devices on the printed circuit board. This is to help the device be soldered on the PCB, and the size of the Paste mask is the same as the size...
If there are any hard bits left in the paste at all, they can scratch my eyeballs if they fall into them. It's kind of a difficult process, even though the ingredients are so simple. I only use it when my skin is truly in need of exfoliation, so I make the mask about once a...
3).Solder mask: solder the green oil layer, which refers to the part of the board to be covered with green oil; Because it is a negative output, so actually part of the actual effect of the soldermask is not green oil, but tin, silver! Paste mask: paste paste layer and welding aid...
So, to prevent PCB from oxidation, applying a solder mask is crucial. Also, Solder Mask offers protection from electrical shorts in the Printed Circuit Board. Without the solder mask application, solder paste interacts with the copper traces on the PCB during assembly. So, when components are ...
A peelable solder mask, also known as a blue mask, is a positive plane (what you see is what you get in the design) used for the protection of the required pads in PCB assembly. A peelable solder mask layer is usually named GTPM and GBPM in design. Unlike the solder mask layer whic...
What is the maximum length of a HiLog record? Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environme...

SMD patch layer] It is used when the machine is patched. Yes, it corresponds to the pads of all SMD components, the size is the same as the toplayer/bottomlayer layer, and it is used to open the stencil to leak tin. Paste mask is commonly known as "steel mesh" or "steel plate"...

The solderability becomes worse: Because the solder mask would be affected by high temperatures present in a reflow oven, which would affect the solder paste’s tin area. Bad pad positioning: The soldermask’s tolerance is larger compared to the copper. Therefore, this might affect the pads’...
