Quantity solder check (solder amount check)
This inspection can be used to detect the fillet area, and determines whether a fillet is formed or not based on that
result.

1.3.2 Inspection with X-ray camera
n
Solder inspection of lower surface electrode parts
•
Ball joint check
Inspection is performed with X-ray horizontal tomographic images obtained with digital laminography. Solder is detected
from X-ray horizontal images of joint surfaces on lower surface electrode parts, and judgment is made based on the
detected surface area and radius.

Solder quantity check
Lead parts back fillet is detected from X-ray images, and judgment is made based on the detected surface area.

Creating inspection programs
2. Creating inspection programs
This section describes how to create inspection programs for inspection machines from mounter mount data.
2.1 Flowchart for creating an inspection program
Press the [Convert] button at the "Setup" screen to convert YAMAHA mounter mount data to an inspection
program. Inspection programs are created by pasting parts libraries to mounting positions. Mount data for third
party mounters is converted to inspection programs after first converting it to YAMAHA mounter data format.
