( A ) How to check Depth of V-groove
1)
Cut a V-grooved solder wire vertically
into 4 pieces by 2 cm intervals.
When cutting, place the V-grooved
section to topside so that it will be
easier to observe it..
2)
Observe each cut section with a lupe
whether it looks almost the same as
below fig. “ GOOD “.
V-groove cut section
GOOD
TOO SHALLOW
TOO DEEP
※
Too shallow
V-groove obtain less effect of prevention of solder balls and flux scattering.
※
Too deep
It makes flux residues stick to V-blade, and then V-blade gets deteriorated easily.
In addition, solder wire may possibly twist around V-blade.
It cause the damage of both of V-blade and guide pulley.
※
Please adjust depth of V-groove flexibly. Appropriate adjusting position will depend on the type
of solder wire, flux size and so on.
It is better to adjust it after using with checking the solder ball scattering.
