Abstract
Embodiments of the present disclosure provide sensors inside an In-Circuit Tester (ICT) that measure stress on a Printed Circuit Board (PCB) every time the ICT runs through a manufacturing process. This ICT can comprise an Internet of Things (IoT) device which can measure, monitor, record, and show stress data that is being exerted by ICTs on the mounted PCB in real-time during tests thereby providing technicians an ability to oversee failures based on historical data that the IoT device provides.
Claims20
An In-Circuit Tester (ICT) device comprising:
- a clamp shell;
- one or more sensors disposed at one or more locations in the clamp shell;
- and
- an Internet-of-Things (IoT) device coupled with the one or more sensors, the IoT device comprising a processor and a memory coupled with and readable by the processor, the memory storing therein a set of instructions which, when executed by the processor, causes the processor to:
- read an input signal from each of the one or more sensors, the input signal from each sensor indicating an amount of force on a Printed Circuit Board (PCB) mounted in the clamp shell, wherein the input signal is read from each of the sensors in real-time while a test is being conducted on the PCB, and
- log a set of results indicating the amount of force on the PCB during the test based on the input signal from each of the one or more sensors.
A monitoring system of an manufacturing and testing environment, the monitoring system comprising:
- a processor;
- and
- a memory coupled with and readable by the processor and storing therein a set of instructions which, when executed by the processor, causes the processor to:
- receive, from an Internet-or-Things (IoT) device, data logged by the IoT device, wherein the IoT device is disposed within an In-Circuit Tester (ICT), wherein the data logged by the IoT device is logged in real-time during a test conducted on a Printed Circuit Board (PCB) mounted on the ICT, and wherein the data logged by the IoT device indicates a force applied to the PCB during the test;
- and
- present, in a user interface, a visual indication of the force applied to the PCB during the test based on the received data logged by the IoT device.
A method for monitoring a manufacturing and testing process, the method comprising:
- reading, by an Internet-of-Things (IoT) device, an input signal from each of one or more sensors, wherein the IoT device and one or more sensors are disposed within an In-Circuit Tester (ICT), wherein the input signal from each sensor indicates an amount of force on a Printed Circuit Board (PCB) mounted in a clamp shell of the ICT, and wherein the input signal is read from each of the sensors in real-time while a test is being conducted on the PCB;
- logging, by the IoT device, a set of results indicating the amount of force on the PCB during the test based on the input signal from each of the one or more sensors;
- and
- transmitting, by the IoT device, the logged set of results indicating the amount of stress on the PCB during the test to a monitoring system.
