becoming totally molten and coalesce forming a homogeneous molten solder volume. If the solder paste appears to not have reflowed and is as identified in IPC-A-610 section 5, the issue is that the proper intermetallic has not formed at both the component and pad/land surface

SnPb solder joints is higher than that of SAC305 solder joint because the wetting of SnPb is better than that of SnAgCu. Figure 14. Cross-section View of SnPb Solder Joint Reflowed at 215C for 90 sec. Figure 15. Cross-section View of SAC305 Solder Joint

: This following information is from Rev D of IPC-A-610. The requirement was to inspect all joints after cutting and make a determination as to whether or not the connection was damaged, then if damage was found, the solder joint was to be reflowed

. The bottom component of the large board is easily dropped during the second reflow process, or the bottom solder joint is partially melted, causing solder joint reliability problems

: We were looking over the J-STD-001 and the Space Addendum requirements for partially visible or hidden solder connections 4.18.3. Why does the space addendum give you the option to x-ray the parts in Note D, but in the J-STD-001 book
