Currently, processes related to PCBs (printed circle board), such as depanelization and checking the correct functioning of the boards, are carried out in separate devices. The purpose of this article is to review the literature and analyze trends related to these aspects of PCB panel manufacturing. The purpose of this analysis is to indicate the currently used depanelization methods and methods for checking the correctness of the assembly of electronic circuits on PCB panels. The publications were found in such knowledge bases as Scopus, IEEE Xplore or Emerald insight. In the following article, a systematic literature analysis along with a mapping study is used. This publication provides a review of selected scientific papers found in the above-mentioned databases. Based on these analyses, insights related to future work on both aspects of PCBs were presented. These insights are part of the development of new integrated devices for depanelization and verification of PCBs.

“…They become more attractive due to the built-in feature such as the programmable memories, analogue to digital converter and programmable input/output timers [7], [8]. These built-in components can be used to host the embedded software algorithm that operates the device based on given requirements.…”

This paper presents the design of a GSM network based z-axis position controlling system for remote monitoring and control. Using this positioning system the height of an object can be controlled and monitored through SMS from any location where GSM network is available. The desired position of an object is sent to the GSM modem by the user through SMS. The embedded system in the positioning device has an algorithm which acquires the current position of the object, processes, transmits and stores it in the built-in Flash memory of microcontroller. Once the desired programmed trigger level of the signal is reached, the microcontroller downloads the current position of the object to the GSM modem. Then, GSM dials the pre-sorted mobile number/s and transmits the current position as a normal SMS to the user, thus making remote monitoring and control of positioning system is easier than the existing techniques.

This paper presents the design and development of a daughter board consisting of stepper motor drivers and serial interfaces. The purpose of this board is to provide embedded systems students with a tool to design and develop automation applications using stepper motors and simple RS-232C serial communications. The stepper motors used is a bipolar six-wire configuration motor. Software drivers for serial communication and the stepper motors are written in the 'C' language using the High-performance Embedded Workshop (HEW) Integrated Development Environment provided with the Renesas Embedded Evaluation Board. The stepper motors are programmed to drive in full step, half step, and micro step mode. The circuit functionality was tested on a breadboard, and on compliance with the performance, a PCB was manufactured.
