Phenolic resin back-up board

The main application for phenolic resin back-up boards is as the protective entry or back-up board while drilling or routing of flexible and/or rigid printed circuit boards (PCB).


    Syndyne’s back-up boards have the following advantages:
  • Smooth and flat surface with no impurities and low warpage.
  • Uniform thickness throughout a single sheet and comply with the market standards.
  • No smear or burr occurrence while drilling.
  • Appropriate surface hardness to ensure no wearing out or shortening of drill bits' lifetime.
  • We have computerised numerically controlled sawing machines and automatic sealing & packaging machines to provide a customised cut-to-size service for our customers.

The typical properties and standard supplying dimensions of Syndyne’s phenolic resin back-up boards are as follows:
