PRODUCTIVITY IMPROVEMENT WITH MACHINERY: CASE STUDY THE ELECTRONICS COMPANY IN WHA CHONBURI INDUSTRIAL ESTATE 2

Abstract

This study aims to study the current process of printed circuit board (PCB) assembly in the selected case study company and to propose strategies for enhancing the company’s production capabilities. The research identified an opportunity to improve the adhesive dispensing stage by replacing manual operations performed by daily workers with a custom-designed machine. This machine was constructed using repurposed components and spare parts already available within the production line. As a result, the average production time per unit was significantly reduced from 11 minutes and 53 seconds to 3 minutes and 8 seconds—an overall decrease of 8 minutes and 45 seconds. Furthermore, productivity increased from a target of 240 units per week to 245 units. The required number of workstations decreased from 1.3 to 1.0 based on standard time, while maintaining the same number of daily workers. The implementation of Kaizen principles in the improvement of the TX2 adhesive process contributed not only to enhanced production efficiency but also to cost savings of 24,675 THB per quarter, or approximately 98,700 THB annually.
