“…Yunardi and Imandiri [22] designed a 3D scanner based on a line laser and cameras to capture the contour of the human wrist. Even though this scanner can be used to scan the human hand, the resolution of the result is low, and the average Root Mean Square Error (RMSE) between the reconstructed point and the reference point can reach up to 0.47 cm.…”

“…The stepper motor moves in discrete steps, one way to control a step motor using micro stepping. Micro stepping performed by applying a PWM (pulse-width modulation) to control the current to the motor windings [13] . Micro stepping consists of three selectors (20, 30, and 70), which resulted in three modes of motion resolution.…”

In the technology to create prototypes for electronic hardware is usually constructed using surface mount device printed circuit board (SMD PCB). In this paper introduces the design and implementation of low-cost electrical solder paste dispenser that supports the PCB solder process. The design consists of a nozzle and linear drive systems based on stepper motors operating with electric power to push the plunger down to drop the solder paste on the board. To test the performance of solder paste that has been designed verified by experiment. Solder paste dispenser design was tested using SMD resistor with the solder pads of different sizes for R0603, R0805, and R1206 on PCB. The results showed that the design of the prototype was able to put the pasta in various field pads between 0.54 mm2, 0.91 mm2 and 1.44 mm2 for standard solder pads with an error in the 2% - 5%. Based on the results, the device has been shown to potentially be used to attach electronic components to printed circuit boards.
