As a standart we use for production of PCBs materials, produced by company DOOSAN (Korea). Before sending us your inquiry, you can choose a required specification here.
If there are special requirments to the materials (for example:you need to have a special dielectric constant of the material) we use materials produced by company TACONIC KOREA. Before sending us your inquiry, you can choose a required specification here.
