Dear Refaat
Thank you for your responce there is not written solder mask thickness as a
standard some of them say it evaluate it vwith 500 VDC I mean ýt depends on
withstanding voltage but I think general range is between 10 microns and 30
microns
Have a nice Friday

Hi Yusuf,
The specification, for one of the big OEMs that I'm dealing with, has the
thickness for LPI solder mask as 0.0004" minimum (at the crest of the
conductor) and 0.002" maximum (over bare laminate).
Sherif Refaat,
