Thanks to a rapid ramp-up in production volumes at its Republic of Ireland plant, AVX has decided to concentrate production of its passive component arrays at Coleraine and stop production in the US.
Scott Tripp, project director at AVX, said: "The array has become a major success story over the last two years. We are building five million a day in Coleraine. Nine months ago, we were building 1.5 million, so the ramp has been enormous.
"The capabilities are so good that production is being concentrated, with manufacture ceasing in the US. We put a huge amount of pressure on the people at Coleraine but their response has been tremendous."
Coleraine has been the focus of a £54m expansion programme unveiled last October, with much of the money going into the plant's passive arrays manufacturing line. After a slow start, passive arrays are now picking up sales rapidly in high-volume designs.
"There are two main reasons why anyone would want to design in and buy arrays: to save space or money, or both," said Tripp.
He says the focus on cost savings for surface mount capacitors and resistors has shifted to their assembly or 'conversion' costs.
"With the very low price of ceramic capacitors, it is very difficult to save money on price. Even if you do very well and get a supplier to reduce the price by 5 or 20%, you are talking peanuts," said Tripp.
"The conversion cost for a part is about 2 cents per component. With an array, you can save three or four placement costs and many arrays will cost less than 6 cents. It's almost like getting free capacitors."
