Description:

Solexir-Aluminum etchants series consist of Al-110A, Al-110B and Al-110S.  Al-110A is an acidic based solution, Al-110B is an alkaline based solution and Al-110S can be Al-110A or Al-11B, but with surfactant. These acidic/basic/surfactant solutions have different etch rates and surface tensions. Therefore, due to possible existence of complex structures underneath of aluminum layer, Solexir is offering a wide selection of Aluminum etchants solution for different applications.  In addition, Solexir offers customized Aluminum etchants for customers who have special needs.

Application:

Solexir-Aluminum etchants are used in applications where Aluminum metal layers have been used for inter-connectivity between devices.  For more information, please contact us.

Cleaning process:

  • Process Temperature is about 42-45 degrees C.
  • Mechanically agitating the cleaning solution, or performing the cleaning process within a Sonication, or use of spray system is highly recommended. Without agitation, due to formation of hydrogen gas which is a byproduct of the etchant, Aluminum cannot be etched uniformly and one can see a lot of island spots on the surface of Aluminum.
