LtF E-52
LtF E-52 is a copper seed etching solution for Fan-out process.
◆Features
1. Effectively preventing galvanic corrosion of copper fine pattern.
2. Weakly alkaline etching solution
3. SUS tank can be used because solution is halogen-free.
4. 2200 and 300 nm/min of etching rate through spray and immersion etching respectively.
