Marking Information
Starting with 9, a bar on top of 9 is for production
year 2005, and underlined 9 is for year 2006. The
naming pattern continues with consecutive
characters for later years.
The last character is the week code. (A-Z: 1-26,
a-z: 27-52)
A dot on top right corner is for lead-free process.
LF: lead free.
