Solder or solder leakage inspection

When soldering or brazing is done by hand by a person,

Its shape is often unstable.

There was a theme of visual inspection to see if the brazing was actually done properly.

I tested with that work sample.

It still took a lot of time to set up the system because there was a lot of variation.

Because our software is characterized by good registration and good sorting,

When good products fall apart,

The range of good products is wide.

The brightness (density) of a single pixel is statistically processed.

I can do upper and lower limit images,

The range would be too great.

Besides, the shape of the product must be stable,

It is also difficult to position*.

It took a few tries and the end result was good.

Narrow the scope of inspection.

Just the part that should normally be brazed,

I COULD TELL THE DIFFERENCE ONLY AT NG.

It takes know-how, though, from the way the lighting is applied to the settings,

There are always effective measures.

*Positioning is the first key part of the inspection.

We need to align them so we can inspect them.
