Common sensor faults with 4 solutions
Sensors can sometimes fail, and at this point, customers feel that their investments are ruined and they lose trust in sensor suppliers and their brands. Below are four common sensor failures that can occur and how to resolve and eliminate them.
3. Printed circuit board (PCB) problems
Printed circuit boards (PCBs) are an essential component of many popular electronic products, such as smartphones and IoT devices. However, if PCB manufacturers and designers do not pay attention to the PCB and any sensors around it, it is likely to cause product failure. First, for most PCBs, it is best to avoid routing at 90 degrees because this type of wiring tends to increase electromagnetic interference, and excessive electromagnetic interference can cause product defects.
In addition, the use of manufacturability design (DFM) helps PCB manufacturers avoid problems that may arise during production. Perform a manufacturability design check on the PCB to check if the device layout on the PCB could damage the manufacturing and assembly process. For example, when you use multiple sensors in an IoT device, remember that it is necessary to check the hot area of the PCB and evaluate possible temperature changes and whether this temperature rise will damage the sensor.
