We got parts EPF10K30RI208-4N DC:17+ with INK marking, but according to some information for this parts the marking should made by laser method. But suplier told even for now some factories producing this series Altera with INK marking.

Hi Pavel, For your information by referring to ADV 0217, Intel FPGA (Formerly known as Altera) plans to introduce the full laser marking towards the end of March 2008. https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/pcn/adv0217.pdf Are you sourcing the part from the authorized distributor as suggested below? https://www.intel.com/content/www/us/en/programmable/buy.html Thank you Regards, Chia Ling
