We'll be adding Thermal Tabs to CQFP and CFP in the upcoming V2020 Library Expert. 

Due for beta release in March. 

Note: this new feature might not make the first release, but it is planned to add it ASAP.

When creating a flat pack package IPC-2221 8.4.2 covers the basic formula but the Land Pattern Creator does not calculate these for you. You need to know the dimensions in order to create a Land Pattern, if this were the case then couldn't I just use the SOP tool to create my landpattern? Would be nice if the CFP option would calculate the CFP landpattern dimensions 'L', and 'T' based on the IPC flat-pack formula? Also, I do not see the option for a thermal tab on the CFP calculator.]]> Wed, 05 Feb 2020 10:07:40 +0000 https://www.PCBLibraries.com/forum/flat-pack-calculations_topic2601_post10603.html#10603
