Product Properties<\/th>\n<\/tr>\n<\/thead>\n
Description<\/td>\n\n Transene Copper Etchant 49-1 is a high purity, controllable etchant designed for specific microelectronic etch applications such as gallium arsenide or copper. It is compatible with lead-free solders (100% tin, 97%-tin\/3%-silver), as well as gold, nickel, and nickel-vanadium alloys.
\n Copper Etch BTP provides a faster etch rate while maintaining nickel compatibility.\n <\/td>\n<\/tr>\n
How to Increase Etch Rate?<\/td>\n\n 1. The rate will approximately double with every 10\u00b0C increase in temperature.
\n 2. Increase the rate of stirring or agitation.\n <\/td>\n<\/tr>\n
How to Reduce Etch Rate?<\/td>\nAdding 1 part deionized water to 2 parts etchant will reduce the rate by approximately 50%.<\/td>\n<\/tr>\n
Do I Need to Dilute?<\/td>\nNo, it is ready to use.<\/td>\n<\/tr>\n
