MINNEAPOLIS -- Inspection equipment OEM CyberOptics reported second-quarter net income rose to $969,000, up from a net loss of $1.92 million last year.

For the period ended June 30, the company had consolidated sales of $16.5 million, up 34% sequentially and 219% from a year ago.

Operating income was $1.19 million, up from $257,000 in the first quarter and an operating loss of $3.97 million in the second quarter 2009.

Sales of inspection systems rose 44% sequentially and 163% year-over-year. The company reported record unit sales of its SE500 solder paste inspection system in the quarter, naming Quanta as one of its customers, and strong sales of its SE350 mid-range SPI.

"CyberOptics is capitalizing upon the ongoing upturn of the global electronics market by garnering new customers and extending our penetration of our existing customer base through our offerings of alignment sensors and the new-generation inspection systems developed over the past several years," Chief executive officer and chair Kathleen Iverson said. "Reflecting pent-up demand for alignment sensors by manufacturers of robotic pick-and-place equipment, including Juki, Assembleon and DEK, sensor sales were up 27% from this year's first quarter and 439% from last year's second quarter.

CyberOptics ended the quarter with a backlog of $12.9 million, up from $11.7 million sequentially, the majority of which is scheduled to ship in the third quarter. The firm guided for third-quarter revenues of $15 million to $16 million.

"We believe the global electronics industry is in the early phase of a multi-year upturn, driven in part by the onset of business spending on a PC refresh cycle," Iverson said. "We are optimistic that our overall sales and earnings levels will be highly positive during coming periods."
