Title: Method for analyzing shape of solder
Inventor: NUMATA MUNETOSHI
IPC: H05K3/34
Filed: 1992-05-13
Abstract: PURPOSE:To accurately analyze the shape of a solder fillet by introducing an appropriate model function to the shape of the fillet and finding the curve of the shape and required positional coordinates. CONSTITUTION:The meniscus shape formed by a fillet 2 is given by formulae I and II when the fillet angle at an arbitrary point P (x, y) on the curved surface of the fillet 2 is theta. The reflecting point formed on the fillet 2 by illuminating light 6 is represented by P1 and another reflecting point formed by another illuminating light 7 is represented by P2. The angles of the light rays 6 and 7 are respectively represented by PHI1 and PHI2. The front positions (0, 0) and P0 of a lead and fillet 2 are given by using the illuminating light immediately above. The fillet angles theta1 and theta2 at the points P1 and P2 are respectively given by theta1=(pi-2PHI1)/4 and theta2=(pi-2PHI2/4 and a fillet curve is decided by finding correction terms (a) and (b) and the fillet angle theta0 (contact angle theta1) at a point P0 by using the values of the position (x) and fillet angles theta at the points P1 and P2 for the formulae I and II and finding an unknown number (c) by using the coordinate values (x0, 0) at the point P0. Therefore, the contact angle thetah and fillet height (h) of a point Ph where the fillet 2 comes into contact with a lead 1 are found.
