CALCULATION AND LAYOUT DESIGN OF ASSEMBLY SYSTEM AND DETECTION OF PRODUCT ERRORS IN ELECTRONIC CIRCUIT BOARD MANUFACTURING

Abstract

The research team investiged and analyzed data related to the assembly
process and detected errors in electronic circuit board manufacturing, work
stations, movement øow, number of workers and real operating time of the
machines during the production process. From that, calculate and determine the
location of work stations, distance, area, space and build the overall plan of the
system. The results of calculating the coordinates of the work stations using Lingo
software are D (X1, Y1) = (10, 4); E (X2, Y2) = (10, 3.99); F (X3, Y3) = (9.99, 3.99)
respectively. Based on the found coordinates, design and simulate the system
using Tecnomatix Plant Simulation software. Simulation results using factory
simulation show that the production rate on the assembly line increased by more
than 11%. Comparing before and after the change, the added value is quite high
at 71.6%. The initial input products of 400 products/day has increased to 440
products/day, including errors during the production process.
