Ferro电子材料公司在金属密封胶方面进行投产建设，生产出了NS33-514和NS33-515两种型号密封胶。据公司称，这些密封胶尽量充分利用了无机和有机性能确保他们与双重印刷流程更加兼容。
Ferro Electronic Materials has launched two new print-on-print metallization pastes: NS 33-514 and NS 33-515. According to the company, these pastes have optimized inorganic and organic properties that make them compatible with the double-printing (print-on-print) process.
Double-printing of metal grid lines permits solar cell manufacturers to print taller, narrower lines, reducing the shadowing effect caused by wide grid lines, while enhancing electrical conductivity, the company says. Double-printing is experiencing strong growth due to the potential for better print resolution and subsequent increases in efficiency.
Ferro's NS 33-514 and NS 33-515 are capable of printing grid lines that are 70 microns wide, with a greater than 0.3 aspect ratio.
