The researchers worked with sodium beta-alumina in its liquid form, which enabled them to spread it easily onto a surface in precisely the pattern required for a printed circuit.

研究人员可以在钠β-氧化铝处于液态时对它进行操作, 这样就很容易将它精确地涂抹在物体表面, 而这正是印刷电路板所要求的工艺模式.

In addition, the solder mask coating on printed circuit board, with the plasma treatment, can also obtain certain roughness and high active surface, thus improving the solder coating adhesion.

另外，在阻焊膜涂覆前，用等离子体对印制电路板面处理一下，还可获得一定的粗糙度和高活性的表面，从而提高阻焊膜层的附着力。
