Switch, Button and

Indicator

The process starts with loading the dimensions,

pin assignments, profile, and batch number into the

system computer. A tray of RAM modules is then

placed in the machine, and the operator presses a

button to start the test.

PCI-1750 starts by using a digital input for a sensor

that detects the presence of the RAM module tray.

If present, digital output channels are used to turn

on the activation light and inform PCI-1240U that

it is time to start moving the modules. PCI-1240U

responds by using three of its axes to pick the first

module from the tray and place it into the fixed

motherboard. When placed, PCI-1750 uses a digital

output to turn on the power of the motherboard.

Software running on the machine’s computer fills the

memory of the RAM module with a pattern, which is

then read back and checked to see if anything had

changed. If not, the module has passed the test and

is placed in an output tray leading to the packaging

machine. If there is an error, the module is moved to

a tray for defect modules. No matter what the result

is, the system records the test result in a database

over an Ethernet connection, together with the serial

number of the RAM module.

The test continues with the pick-and-place tool

moving to the next RAM module on the tray until

all are tested. While one tray is being tested, the

operator prepares the second tray.

Conclusion

•

The new system is entirely based on industrial PCs, meaning maintenance and operation has

been considerably simplified

•

The PC-based system provides a larger memory and an open architecture that is easier for

programming and expansion
