RELQAFA
Guest	Posted: Sat Oct 01, 2026 7:29 am    Post subject: Pb-Free   Hi, Can reflective measurement be used to determine the type of tin finish like matte or bright? A lot of articles published used grain size to determine that. Also I have not seen any articles yet for semi-bright tin? Is there one, if yes what should the grain size be and the carbon content? ThankQ
