JCr-13

It is a Cr-Ni-only etching agent used for finely and precisely etching Cr-Ni layer used in semiconductor and LED process and forming metal pattern.

JCr-13

Nickel, Chrome Etchant

It is a Cr-Ni-only etching agent used for finely and precisely etching Cr-Ni layer used in semiconductor and LED process and forming metal pattern.

Features

  • It is a strongly acidic etching agent and effectively removes the Cr layer, leaving no residue.
  • The strong oxidizing power makes etching speed fast.
  • It is suitable for precision etching process of metal pattern.
  • There is no reactivity with PR (Photo resist) and no undercut phenomenon occurs.
  • If the performance of the product falls, you can easily replenish the new one.
  • It reduces the amount of gas generated during use and enables safe operation.
