Setting up a scenario

 Top  Previous  Next

To demonstrate the ProBalance scenario creation process, a cell phone assembly with four different model options will be used as an example.

 

Cell Phone Model Types

1.Basic: A cell phone with a case, battery, keypad, and display.
2.Standard: A cell phone with a case, battery, keypad, display, and speaker.
3.Deluxe: A cell phone with a case, battery, keypad, display, and camera.
4.Supreme: A cell phone with a case, battery, keypad, display, speaker, and camera.

 

Along with the models, optional parts can also be associated with these cell phone models.

 

Cell Phone Options

1.Battery: 4, 6 or 8 hour durations
2.Display: Regular or Color
3.Camera: 1.5x or 3x optical zoom

The assembly process is as follows.  Based on the model type, each cell phone may or may not require every task listed.

 

1.

Assemble the lower case and place the circuit board (use fixture01).

2.

Place the microprocessor in the circuit board (Figure 2).

3.

Place the ROM, radio section, and the power unit next (use the soldering gun).

4.

Place the camera phone unit.

5.

Place the flash memory card into the card slot and secure (Figure 3).

6.

Place the display unit to the circuit board next (use fixture02).

7.

Next place the keyboard pad on to the upper case (Figure 4).

8.

Next attach the speaker unit (use fixture03).

9.

Attach the battery to the board.

10.

Test battery with test unit BT90 (use testing device BT90).

11.

Attach the antenna to the circuit board and secure the upper and lower case together.

12.

Inspect part for defects (use testing device ISP765).

 

 

Setting up a scenario in ProBalance is a four step process,

 

1.

Setting up Model Data:  The model editor will contain the four basic models with their demand percentages defined.

 

2.

Setting up the Resource Data: The resource editor will list all fixtures, solder guns, and test devices.

 

3.

Setting up the Station Data:  The station editor should list all stations needed for the process and the resources available at those stations. For this example, there will be five stations (ST01, ST02, ST03, ST04, and ST05).

 

4.

Setting up the Task Data:  Enter data on all the tasks (mentioned above), their corresponding times, and the tools they require.
