IC testing firm King Yuan Electronics (KYEC) has announced that revenues for the fourth quarter of 2012 slipped 7.8% sequentially to NT$3.28 billion (US$112.9 million), citing seasonal factors.

KYEC reported December revenues of NT$1.02 billion, down 7.4% on month. Revenues for all of 2012 increased 10.1% from a year ago to NT$12.69 billion, with sales generated from orders for communication ICs and image sensors playing the key growth drivers.

KYEC revealed that it currently utilizes 67-68% of its overall capacity, with utilization rate for logic ICs staying above 70%.

KYEC's sales performance during the first quarter of 2013 will continue to be affected by inventory checks at customers, according to market sources. However, sales after the second quarter will start to gain momentum, the sources indicated.

KYEC said previously that the company will strive for a 70% utilization rate in 2013, so that it can generate a 30% gross margin.
