Photosensitive dry film "Photec"
H series for printed wiring boardsInquiry
- H-7000 series are aqueous type photosensitive films used for high density printed circuit board. H-7000 series can be applied to outer tenting and inner etching process. H-7000 series have excellent tenting ability which is helpful in improving yield.
Features
- Excellent tenting performance is helpful in improving yield.
- High photosensitivity can contribute to improving trough-put performance.
- Excellent adhesion is effective in decreasing the defect of circuit.
