Mark,
In a previous life we measured the thickness of the PCB over solder mask
areas only.
Back then the HASL thickness over bare copper was ( 0.0001 min - 0.001 max.)
Now a days
the HASL thickness is microns thick. Hope this HELP!
victor,

Subject: [TN] Finished board thickness
Hi All,
Here's what was ordered:
0.062" finished board thickness, SMOBC, HASL final finish, IPC-6012 class 2.
Here's the question:
Does finished board thickness include the HASL coating thickness?
Thanks,
Mark Hargreaves
