Ordyl ® FLR 4000

PRODUCT
DESCRIPTION

Ordyl ® FLR 4000 is a negative, aqueous processable dry film specifically designed to be exposed with LDI but usable also with standard UV lamps. FL 4000 is developable and strippable in mildly alkaline solutions and offers superior performances and resistance to leaching in all the most commonly used plating bath in PCB manufacturing.
Ordyl FLR 4000 has good adhesion on copper surface and for this reason is indicated for direct plating process and in case of surface preparation is not good. This type of dry film ensure good tenting performances even on large tooling holes; this can be achieved starting from 40 μm thickness.

Main Features

  • Excellent through cure polymerization also with LDI exposure machine
  • Good adhesion properties
  • High Photospeed
  • High flexibility and conformability

Typical Application

  • Acid etching
  • Tenting process
  • Copper, tin, tin/lead plating

Available Thickness

  • 30 μm (1.2 mils) for standard application
  • 40 μm (1.6 mils) for standard application
  • 50 μm (2 mils) for standard application

Exposure

We recommend using UV lamps or laser source with emission peak at 360 – 405 nm.
We recommend to stay between 7 - 9 Solid STEP of SST21 (7 - 18 Solid STEP of RST25).
