Specific components
For component non listed, operator should use
“generic” type 1, 2, 3, 4 or 19. If the
component is fully wettable on the immersed section, we use type :
1.
For rectangular section
2.
For cylindrical section
3.
For multi rectangular section
4.
For multi cylindrical section
Type 19 is for partially wettable part, see Section 4 for more details.
If the component requests an immersion with angle, the software is not able to define itself
the pass fail limit (and also the wetting angle), operator must define a proper pass fail limit
from experience and
literature and use “user’s specification”
The dipping orientation is normally 90° as we weight in that direction but some component
lead are parallel to the board or complex (J leads), so in this case we use a compromise
between the normal orientation of t
he component during soldering and the “z” axis. (20 to
45°).
Coupons
For coupon, it is important to have the greater wettable area by cutting non wettable area .
The metallization should start at the edge of the immersed side. If there is no contact
between the metallization and the alloy, there is no wetting.
Use type 19 and define total perimeter and wettable perimeter, the immersion depth should
be 3 mm if possible.
The best is to use pre cut coupon designed for wettability testing, with metallization on both
side and eventually on edges. If the coupon is fully wettable on all sections, use type 1.
Video recording
The video recording is accessible from the tool bar or from the video menu and the hot key
F11 to start a video recording.
