MELVILLE, NY -- Printed circuit board laminate sales make up more than 80% of Park Electrochemical's overall revenues, but overall sales to the sector might not return to their pre 2000 highs, the company revealed in a conference call last week.

Non-FR-4 PCB materials represented 82% of total laminate and prepreg material sales in its fiscal fourth quarter, CEO Matt Farabaugh told analysts. Park had overall sales of $42.7 million in the period ended March 3. The recent period included an extra week; sales adjusted to a 13 week period, would have been about $39.6 million, president and chief executive Brian Shore added.

The period from October through March saw low sales, but April was Park's best revenue month in a year and its best net profit month in over two years.

"What's going on in April, I really don't know, but [it was] our best revenue month in about a year and best bottom line month in over two years, I think," Shore said. He did note that the company closed two underperforming facilities, lowering operating costs, however.

Shore said the company might not reach sales of $500 million as it once did, but it was committed to laminates for electronics. "[W]e still feel there is a meaningful place. We feel that we are a company people come to often when they are looking for something special, they're looking for something different, they're looking for continuity, looking for a company that's plugged into the market, understands who the OEMs are and what they want with the customers."

TTM Technologies was Park's largest customer in the March quarter and its only one at more than 10% of total sales. Its other five top customers are Wus, Sanmina, ISU Petasys and Multek. The top five customers made up about 47% of total sales in the quarter.

For fiscal 2013, TTM and Sanmina each made up more than 10% of total sales.
