Packaging and testing company Powertech Technology (PTI) swung to net profits of NT$3.24 billion (US$104.3 million) from losses of NT$3.21 billion in 2013. Net EPS for 2014 came to NT$4.24.

PTI reported consolidated sales of NT$40.04 billion for 2014, up 6.5%, with gross margin climbing 2.6pp on year to 16.6%.

For 2015, PTI will see its quarterly sales register sequential growth through the last quarter of the year, said company chairman DK Tsai at a January 27 investors conference.

PTI's sales for the first quarter will be affected by a seasonal slowdown in demand for PCs and mobile phones, and clients' ongoing inventory adjustments, according to company president YJ Hung. However, PTI expects to see orders pick up after the Lunar New Year holiday, Hung said.

Hung also noted that PTI will receive a ramp-up of orders for SSD-use NAND flash chips in 2015. As for DRAM, demand for mobile DRAM and graphics DRAM chips looks promising.

PTI also provides backend services for logic ICs. The company disclosed that it has started commercial production for clients of high-end flip-chip packaging.

Among all PTI's offerings, backend services for flash and logic ICs will outperform the DRAM segment in terms of growth in 2015, Tsai said.
