4.3.2. Solder transition graph

Transition of the rolling width per board is displayed visually in [Monitor] – [Solder transition].

The horizontal axis is the number of produced board and the vertical axis is the rolling width. The

blue line shows rolling width scan result, the red line shows the ”Error Rolling Width” of board

data, and the green line shows the ”Warning Rolling Width” of the board data.

When solder is supplied (“Yes” button is tapped in “Ea8988:Supply Solder” message), the

“Supply” flag is indicated on the graph to check solder supply timings at a glance.

4.3.3. Inspection result analysis graph

Since the solder fill amount may vary as the solder is supplied, this change may affect the

inspection result. To make it easy to determine whether the effect depends on solder supply, the

“Supply” flag is indicated on the transition graph of the inspection result analysis to check the

solder supply timings at a glance.

5. Limitations

1. This function is specially designed only for the “3S head” of the printer YSP.

2. This function is not applicable to the printer board data in the text format. The board data

must be saved in the YGZ format.

3. If the board data is saved in the conventional printer “YGP”, the “Solder Remaining Quantity

Detection” parameters may be initialized. Upgrade the software to compliant version of the

“Solder Remaining Quantity Detection” function.

4. When editing the “Solder Remaining Quantity Detection” parameters in the Y.Fact Editor,

upgrade the software to compliant version of the “Solder Remaining Quantity Detection”

function.

5. This function is applied for metal mask only. Plastic mask and mesh mask are unusable.

6. The solder rolling width on the mask is scanned on the front side (after backward printing,

before forward printing) only; it is not scanned on the rear side (after forward printing, before

backward printing). This is because “Solder Scan Sensor” is mounted to the rear side of “3S

Squeegee Head”, if the rolling width is scanned on the rear side, the squeegee is located

over aperture of the mask, and adhered solder to the squeegee might be dropped on

aperture.

7. When “Round” printing is set in the board data, print cycle time might be increased because

the solder width is scanned on the way of round printing. In this case, “Ea8984: Print Cycle

Time Might Increase” message is displayed when auto-running is started.

8. This function cannot check whether solder amount is overmuch (rolling width exceeds a

certain threshold width).

9. The scanning distance of rolling width is decided by “Rolling Stroke” and “Over Stroke” of

board data. When the rolling width scan fails because the scanning distance is short, widen

the gap between "Rolling Stroke" and "Over Stroke".

10. When using this function, existing “Solder Supply Stop” function becomes invalid.

11. When using this function, auto-supplying solder function of “PSC (Print Stability Control)”

becomes invalid. However, when the machine equips with “PSC (Print Stability Control)”,

set ”PSC (Print Stability Control)” to ”Syringe Type” or ”Pot Type”, without invalidating it.

(Because safety checks of FX-axis becomes effective.)
