POM Plates Information
We order our POM sheets at 1.5mm thickness though parts of the sheets can vary up to 1.6mm therefore our POM plate thickness vary from 1.5mm to 1.6mm. The POM sheets we receive from our vendor(s) is supplied with no protective paper covering on them & as such the material is prone to surface scratching. We have requested sheets with protective covering but as of now three vendors have told us it is not available. Additionally there may be some heat marks around the cut-out parts due to how the laser cuts the material.
While I account for laser kerf when cutting POM plates, there are many switches on the market and fitment cannot always be guaranteed. Some switches clip in, some are snug and some are loose. While even the loose switches can be soldered with no issues, these switches wouldn't be ideal for a hot swap board.
This seems to be the case with POM plates from most vendors. It's hard to give an exact list of which switches work best as one batch of Tangies for instance would clip in and another batch would just be snug. The only switches that have been consistent with clipping in are NK_ Creams & Holy Pandas / Glorious Pandas.
Below are some examples of the scratches on an uncut sheet as well as a few images of a plate once cut at different angles to show surface scratches. Finally the last image shows the heat marks. I have a new method that reduces heat marks but nonetheless a few marks still can occur. If any of the above are issues for you please do not purchase a POM plate. There will be no refunds on POM Plates due to the flaws mentioned above.
