0201 and 01005 are the smallest chip components both in production or being evaluated by the industry for small and miniature application. They put demands on both process and equipment but what are the practical issues? The 0201 joint in Figure 1 is considered satisfactory with good wetting on both terminations. Some may consider that there is a little too much solder on the terminations. It requires a balance with such small parts to ensure printing and full paste release is not compromised with large stencil apertures. Using very small apertures may cause no paste to be deposited on the pads.
