Note that QFN28-Atmel and QFN28-SiLabs still need verifying. QFN28-SiLabs is quite differnt from NXP's specification. - modules/INFO: added description of solder paste deposit dimensioning rules (based on NXP's AN10365) - modules/qfn.fpd (QFN32-VHHD-2, QFN32-VHHD-6): increased solder paste deposits according to the rules
