Land Pattern / Solder Joint Goals

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi everybody.
I am quite sure to remember the least toe value for rectangular end cap equal or lager than 0603 to be 0.15 mm (according to IPC-7351B).

from the library expert solder joint goal tables i get different values the bigger the components get (0603 already 0.2, 1206 & 1210 have a 0.25mm toe, and so on).

could anyone help me solve my confusion?

Cheers
Beat
