correction
Evident crevices which is visible are rejectable.
1. Failure to mount parts
2. Parts not in the specifications are mounted
3. Polarity, for example, is reversed
1. LSI, IC lead width is more than 50% beyond pad
outline.
2. Chip component is off center and more than 50% of
the leads is off the pad outline.
1. 0.45<φ
,N≧1
2. 0.30<φ<0.45 ,N≧1
φ:Average diameter of solder ball (unit: mm)
3. 0.50<L
,N≧1
L: Average length of solder chip (unit: mm)
1. Due to PCB copper foil pattern burnout, the pattern is
connected, using a jumper wire for repair; 2 or more
places are corrected per PCB.
2. Short circuited part is cut, and no resist coating has
been performed.
