The area of a circle = pi * radius^2 radius = squareroot(area/pi) diameter = 2*radius Is this what you were looking for?

We think maybe 50 thou would be a more approachable corner radius. Why does your customer want to have radiused corners?

We make PCB assemblies for an RGB arc that is made up of multiple curved PCB's that have connectors on the ends to plug together. I think the end the radius of the arc is 2 feet. Jerry

Full radius corners on pads can help with solder paste release in the stencil. The radius shape minimizes the surface area in the wall of the stencil aperture as compared to a sharp corners. When the stencil is seperating from the pcb the solder pa

We also just join multiple boards via connectors.

0.031" radius is a diameter of 0.062" which is very tight (small) for a rounded corner. I would tend to agree with the board house that is can not be done. 0.031" is a standard thickness of PCB. I think it is very possible that your customer swapp

Armin: Boca makes some good points about release. So, let me spin this up from a different angle ... SM-782 suggests "full radius corners" as an alternative to the more familiar square corner pads on PLCC, TSOP and QFP. We see both also. We thin

We used to have our PLCC,s, TSOP's and QFP's (0.65 mm pitch) Land Patterns designed in square corners. Some of our products have them designed in Full Radius Corners. As of now, with the two different designs running in our production floor, we can't

We've talked about assembling on flex previously. Search the fine SMTnet Archives for background. Issues that come to mind [which is very risky, given that this Saturday morning and last night was at Jimbo's] are: * Use carriers that can flow thoug

We actually look at it like this, The area of a circle that will fit into a square is less. (slight overprint with square aperture with radiused corners) Russ
