Why buyers choose RNS

  • Optoelectronics focus. Most of our boards go into LED packages, IR emitters and receivers, photo sensors and sensor modules.
  • Many product types. We also make boards for security equipment (card terminals, communication devices, fingerprint readers) and safe door locks.
  • Gold finish experience. ENIG, hard gold and soft gold for wire bonding, contacts and fine-pitch parts.
  • Special materials. White BT resin, High-Tg FR-4, halogen-free FR-4, CEM-1 / CEM-3 and aluminum.
  • High volume, small size. Lots of tens of thousands to over one hundred thousand pieces.
  • Gold-price-linked pricing. For heavy gold boards we can tie the price to the monthly gold market price.
