  Subject: [TN] Fractured solder joint on component side


  Hi Technetters,

  It is stated in IPC-A-610C that a fractured joint is considered defect in
all classes.  Can anyone
  confirm that it would be the same if the fracture is on the component
side?  And why should
  it be considered as defect if the joint on the secondary side is good.
Would the fracture
  extend from the primary side to the secondary side?

  Thanks in advance...

  JF
