JD1 / JD1HTE (JD1S)
Zinc-free Copper Foil Treatments- Compatible to acidic chemistry in electroless NiAu process
- Fine nodularized treatment increases mechanical adhesion
- Reverse treatment with very low profile high frequency applications
- JD1 especially designed for PTFE laminates
JD1HTE, Grade 3
combines the advantage of the acclaimed HTE-grade 3 copper foil with a zinc-free treatment to prevent any acid undercut in NiAu plating processes. High bond to most of resin systems is maintained by GOULD's zinc-free treatment technology. JD1HTE is recommended for application on high frequency prepregs like PTFE, epoxy-aramide or multifunctional epoxies. Available also as JD1HTEVLP.
Zinc-free Treatment
is Nickel Gold compatible. Acidic chemistry in electroless NiAu processes can undercut the zinc layer underneath fine lines, hence reduce contact area (acid undercut) and peel strength.
High Peel Strength and Reliability in Electroless NiAu Process
The fine nodulized D1 treatment (more metallic than oxidic copper) guarantees optimal mechanical and chemical bond.
Thin Laminate and High Frequency Application
High layer count PCBs in mobile phones or applications in smart cards/labels require thin foils with low treatment roughness.
