Isola and Rogers.
That’s what’s left of the US-owned laminate companies today after Taiwan’s Elite Material Co. announced plans to acquire Arlon EMD.
Yes, consolidation has been in the making for years. And with Isola owned by private equity group (Cerberus Capital Management), it’s anyone’s guess as to how stable that number is.
In reality, it was only a matter of time. The US share of global PCB revenues fell from north of 40% in 1984, to about 30% in 1998, to less than 8% in the recession of 2008. It now stands at roughly 4%. Naturally, the supply base is going to migrate to where the revenue is.
Time was, the US was home to several leading names in laminates: Polyclad (now owned by Isola), Westinghouse (acquired by Allied-Signal in 1992), GE (licensed to Cookson, now sold by Isola), Norplex Oak (sold by Allied Signal to Isola parent Ruetgers in 1999, then everntually shuttered), Taconic (bought by AGC), Nelco (ditto), among others. For its part, Arlon was acquired by Rogers in 2014, which then sold part of it to a private equity group the next year. That unit became Arlon EMD, which Elite is buying.
This is not to say there aren’t domestic sources of materials, of course. There are plenty: Ventec and Shengyi are among those that have expanded in the US in the past few years. A startup called Thintronics, with experienced laminate folks like Tarun Amla at the helm, has potential, but is likely years away from impact. There remain domestic flex circuit suppliers too, including DuPont and Sheldahl.
But the vast majority of multilayer and high-performance specialty material suppliers are held by offshore companies. As the US seeks to build back its manufacturing base, it needs to remember how critical the supplier infrastructure is to a successful industry.
