  • PLAZMARK™ for Desmear


Easily manage the plasma desmear process without the time-consuming weight measurements

This is a label-shaped indicator capable of being affixed for use in plasma desmearing of printed wiring board via hole structures.
It has compatibility with the O₂+CF-based mixed gases often used in plasma desmear. It can also be used for high-intensity plasma processes involving high output power levels and extensive durations, whereas other products in the PLAZMARK™ lineup would exceed the maximum range. Due to its flexibility, this product can be affixed upon a flexible substrate and transported by roll-to-roll plasma desmear equipment.
