WE PROVIDE SOLUTIONS
In order for one to be able to compare the different materials, here-below is a presentation of the materials we most commonly use in our Printed Circuit Boards such as FR-4 and Aluminum (SMI)..
If one wishes to use other base materials we are open do this (as long as materials are available and following our suppliers purchasing conditions) after a full study from our Technical Dept.
