TL;DR: In this paper, a circuit board temperature distribution rapid test method based on a small amount of measurement point data is proposed, and the method comprises the steps: sorting circuit board power devices from high to low according to the working temperature, and selecting the first s devices as key components of a to-be-tested temperature value; acquiring temperature values of the key components by using a thermocouple measurement method; determining the thermal power consumption of each key component; determining thermal resistance of each k component; obtaining geometric coordinates of each K device; fitting the temperature distribution of the circuit board

TL;DR: In this article, a convolutional neural network (CNN) was used to estimate the capacity of the battery. And the output value of the CNN is the capacity estimation value for the tested battery.

TL;DR: In this article, a system reliability model construction and evaluation method based on incomplete state monitoring data learning composed of a system,, a subsystem and a unit is presented, where a Bayesian network model of the system can also be established by utilizing missing data under the condition that the data is missing and the reliability of the multi-state system is evaluated.

TL;DR: In this article , a millimeter-wave multi-layer antenna-in-package design for 5G applications is proposed, where a patch antenna is designed in the package with HDI stack-up based on liquid-crystal polymer (LCP).

TL;DR: In this article, a multi-physical field simulation and response surface analysis method was used to optimize the reliability of a lithium battery pack system, where a redundancy design scheme was formulated according to the size and reliability requirements of a battery pack physical model, and a response surface experiment scheme was designed by determining abattery arrangement mode and to-be optimized design parameters.
