Re: [TN] Post solder Component lead trimming






Victor,

J-STD-001 Rev E Para. 6.1.4 states that leads trimmed shall have the 
solder reflowed or inspected at 10X for damage.
And if the trim cuts into the solder fillet, it must be reflowed.

Subject: EXTERNAL: [TN] Post solder Component lead trimming

Fellow TechNetters:

   Does IPC Standards address the lead trimming of components on post 
solder assemblies.   I heard that on post solder lead trimming that a 
second pass solder operation is required to ensure solder joint integrity 
from the lead trimming process.   Any comments and/or direction for 
literature review.

Victor,
