Product Description

1100/1050/1060/3003 Aluminium PCB drilling entry sheet foil

Product Description
Aluminium drill entry sheet is manufactured for use with double-sided and multilayer circuit boards to meet both the performance and cost requirements for general PCB drilling.
 
Features
1. Excellent heat dissipation of aluminium drill entry sheet cools the drill bit to reduce the risk of resin build-up in the flutes.
2.  Defined surface roughness combined with excellent flatness is designed to benefit drill centring, reduce drill wander and avoid drill breakage.
3.  Excellent burr reduction due to high surface hardness and material stiffness
4.  Protects the circuit board against scratches and pressure foot marks
5. Thickness options available for different applications
6. Solid aluminium drill entry can be totally recycled.

Technical Data
Temper: H 19 extra hard
Elongation: > 3 %
Surface roughness: approx. 3.5 µm
