《Supplement information》
The example above explains how the tool works on occurrence of a micro crack in the flat cable. If a complete
disconnection occurs, the LED will light red from the beginning or it will turn red after SW2 is pressed.
Example 1: 0.5 mm-pitch flat cable disconnection check
1. Connect flat cables 3a and 3b under test to connectors J02 and J01
of the flat cable checker, respectively.
2. Load a battery into the flat cable checker for the flat cable connected
to connector J01.
3. Slide SW1 to ON to switch on the PCB. If the green LED turns on at
this time, go to 4.
If the red LED turns on, there is a full disconnection.
4. Touching the flat cable under test by hand, check to see if the LED
turns from green to red.
If a disconnection occurs momentarily, the LED will turn red, which
means a partial disconnection.
Example 2: 1 mm-pitch flat cable disconnection check
1. Connect flat cables 3a and 3b under test to connectors J1002 and
J1001 of the flat cable checker, respectively.
2. Load a battery into the flat cable checker for the flat cable connected
to connector J1001.
3. Slide SW1 to ON to switch on the PCB. If the green LED turns on at
this time, go to 4.
If the red LED turns on, there is a full disconnection.
4. Touching the flat cable under test by hand, check to see if the LED
turns from green to red.
If a disconnection occurs momentarily, the LED will turn red, which
means a partial disconnection.
