在同等放大倍数下,CuP钎料钎焊接头处气孔尺寸最大的约200μm,而CuPSn钎料钎焊接头处气孔尺寸最大的约150μm,并且CuP钎料钎焊处气孔数量要高于CuPSn钎料。
Under the same magnification, the largest pore size at the CuP brazing joint is about 200μm, while the largest pore size at the CuPSn brazing joint is about 150μm, and the number of pores at the CuP solder brazing is higher than that of the CuPSn solder.
