Good morning Tan,

I ran into the same problem a while back but found an excellent source
of process info on the component manufacturer's website. Check out
Linear Technology's Application Note 100, "Recommended Land Pattern
Design, Assembly and Rework Guidelines For DC/DC uModule in LNA Package"
document. It is the best source of LNA type process and accept-reject
info that I have found readily available. Sorry but I do not have a link
to their website.  Good luck

Best Regards,
-Joe

Hi All, base on IPC-A-610D, there is no explicit requirement for LGA,
all it says about Surface Mount Area Array is "for devices with solder
balls that collapse during reflow". Is there any IPC
standard/specification define the void on LGA? Thank you all and have a
nice day!
