I have dealt with it before and usually it's consistent, so you use some simple math to work around the issues. Now, if you have so much variability between different locations on your board for resist thickness, HASL thickness, etc., that it fouls

Guys, If there are any specifications or ciriterions for solder paste deposition thickness and volume evaluation. For example, QFP (0.5 mm pitch), 6~8 mils, 3000 mil^3 PLCC: 8~10 mils, ... . . Thanks in advance. Best Regards,
