Soft Etching Series
● What is Soft Etching Series?
- The HMC series produces excellent copper surface irregardless of the copper material used in the PCB manufacturing process.
In addition, it is a soft etchant of sulfuric acid and water type that provides strong adhesion between copper and dry flim reist which is essential for fine pattern formation.
● Uses and Features
▶ For preprocessing of D / F, S / R
: Dry film resist, Solder resist
▶ Uniform illumination forming a copper surface after etching
: Improve adhesion to dry film and ink
▶ Excellent stability of hydrogen peroxide
: Available both Spray and dip process
