Hi,
Is there anyone experience in handling WQFN component.
This type of component is from NEC. I am not able to find
out much about this type of package.
I am seeing abnormal solder fillet formation. The fillet is
not smooth joint, but rather showed to be 'dewet' ?
I hope someone who has experience in assembling this
component, can share his or her experience, such as
what type of reflow temperature, solderpaste type,
he/she is using, and how the fillet formation should look
like.
Thanks.
Poh
