What do you call a rounded square

I would imagine that talking about the use of "squircles" during a logo presentation to a board of execs would be met with confusion and laughter. It's very esoteric so I doubt this word would be readily consumed outside of design professionals. Show 4 more comments. Helena Handbasket Helena Handbasket 19 2 2 bronze badges.

This sounds as if you just made it up. I agree, it is : — mayersdesign. Could you edit your answer to include at least the reasoning behind the word 'squeaf' and why you think that's a good name for this shape? Feel free to browse around the site, add more answers and maybe ask a question of your own.

While fun words are great for teams of 1, it doesn't transition well to a real development cycle. This comment was just about adding extra rationale behind not making up words as an official answer — TheGeekZn. Sign up or log in Sign up using Google. Sign up using Facebook.

Aperture shapes tested for transfer efficiency, variation and deposit volume. Comparing apertures of the same major dimension diameter or side length and area ratio, we were able to directly compare transfer efficiencies, actual deposit volumes and volume repeatability of the three shapes.

DfM experts purport the squircle as the optimized aperture design for fine features. A square has the inherent benefit of maximizing the area of an aperture. When printing solder paste, however, the particles tend to agglomerate into sharp aperture corners, resulting in more variation from deposit to deposit. It is also likely this variation will grow over time if the stencil wipe efficacy diminishes and the paste accumulation increases.

Squares inherently have higher volumes than circles for the same major dimension, so of course they will deposit more paste, but if those paste-grabbing corners overlap pad edges, they also create gasketing problems that can drive high variation. Circles have no pad-overlapping corners and no paste dead zones, thus eliminating the two major issues associated with squares. But because of their lower aperture area they inherently print less solder paste. Additionally, circles have equal surface tension across the diameter of the aperture.

Best answer: A 'curved square' may be the best you can do. Here's a curved square plate. A chamfered square? I think that's called a "lozenge". Best answer: Why not a Reuleaux square? See pages 4 and 5 of the article "General Reuleaux Polygon in Mathematics" [pdf] for figures.
