Circuit assembly business was a big part of LG group in the past 20 years, belonging to LG Innotek. However, because the fast Chinese economy development, Innotek was forced to give up this business.
On November 28, according to BusinessKorea, LG Innotek will withdraw from the circuit assembly and strategically transfer labor and resources to the semiconductor business.
LG Innotek announced that it has decided to terminate the printed circuit board (PCB) business, which is an HDI business and accounts for 3.1% of the company’s total sales. LG Innotek is expected to end PCB production within this year and stop selling PCBs in June next year.
LG Innotek explained that the circuit assembly was suspended due to declining demand for high value-added products from mobile devices and increased competition, which has led to the suspension of the business. Earlier, the company had said it was considering various plans, including exiting the HDI business to streamline its substrate business.
