RBP Chemical Technology Announces the Release of ONYX™ Direct Metallization System for PCBs


Reading time ( words)

RBP’s ONYX™ is a Direct Metallization System for high reliability and complex printed circuit boards.

The RBP ONYX™ Direct Metallization Process is an integrated system based on a highly conductive form of finely dispersed graphite. Extensively tested and validated, the ONYX™ Process has proven to be versatile and cost effective. Currently the customer base using ONYX™ processes flex, rigid-flex, HDI and high aspect ratio multilayer printed circuit boards with ease and cost effectiveness when compared to conventional electroless copper. The ONYX™ process easily surpasses industry reliability standards including IST (interconnection stress test) and ATC (accelerated thermal cycling).

ONYX™ Direct Metallization System Highlights

The ONYX™ Direct Metallization System is a versatile process and is used in horizontal conveyorized equipment or in vertical immersion mode. Fabricators are able to process a vast array of resin materials including PTFE, polyimide, BT, flex, and basically all epoxy-based resin systems on the market today.

This process is an alternative to electroless copper deposition and provides several significant benefits to the fabricator:

  • Less expensive than conventional electroless copper
  • Smaller equipment footprint compared to electroless copper
  • Greatly reduced water consumption, 4−6 gallons/minute, compared to conventional electroless copper, 26−30 gallons per minute
  • ONYX™ contains no chelator as opposed to electroless coppersimplifying waste treatment

What’s Driving Price Increases for CCL and Prepreg?

01/20/2021 | Mark Goodwin, Ventec International Group
Demand for copper foil is increasing from both PCB and battery production for e-mobility, leading to an upward price pressure for copper foils as post lockdown pent-up demand starts to exceed capacity. Lead times are stretching and prices increasing, particularly for heavy copper foils (2 oz./70 micron and above) as capacity is repurposed to maximize square-meter output for lightweight foils to increase capacity for lithium battery production.

EIPC Technical Snapshot: PCB Surface Finishes

12/28/2020 | Pete Starkey, I-Connect007
For the third in a series of Technical Snapshot webinars, EIPC chose to focus on PCB surface finishes, comparing specific properties, examining corrosion behaviour and discussing selection criteria for low-loss, high frequency applications.

Prices of Copper-Clad Laminates Continue to Rise

12/18/2020 | I-Connect007 China Team
Forces within and outside the PCB industry have led to concerns over rising prices for raw materials of copper-clad laminates (CCL). Recently, two major explosions at epoxy resin plants in China had a great impact on domestic resin suppliers. Prices have risen steadily in 2020, with leading CCL manufacturers announcing price increases of 20-30% recently. As the cost of raw materials such as electronic copper foil, resin and glass fiber have risen, the cost for manufacturing CCL has taken off as well.
