Steve, This is a good, well repeated, not identified by IPC yet issue. I, and some others in industry, for years have proven and recommended smaller pads for various devices. I, and some others in industry, use 0402 pads for 0603 device types. IPC o

Is the board a two sided smt board? If so, where are the standoffs (board supports) located during the second side run? The 0805 being thicker than the 0603 may explain why 0805 was cracked less.

IMS announced today that the A-0402WA attenuator is now available taped face-down in the pocket. The part number for this orientation is IMS2652. This taping arrangement has previously been available for the A-0603 (IMS2533) and A-0805 (IMS1141) sizes. Now all three of the most popular sizes of the A-Series are available in both face up and face down arrangements.

Reflow profile has significant impact on solder joint performance because it influences wetting and microstructure of the solder joint. The degree of wetting, the microstructure (in particular the intermetallic layer), and the inherent strength of the solder all factor into the reliability of the solder joint. This paper presents experimental results on the effect of reflow profile on both 63%Sn 37%Pb (SnPb) and 96.5%Sn 3.0%Ag 0.5%Cu (SAC 305) solder joint shear force. Specifically, the effect of the reflow peak temperature and time above solder liquidus temperature are studied. Nine reflow profiles for SAC 305 and nine reflow profiles for SnPb have been developed with three levels of peak temperature (230 o C, 240 o C, and 250 o C for SAC 305; and 195 o C, 205 o C, and 215 o C for SnPb) and three levels of time above solder liquidus temperature (30 sec., 60 sec., and 90 sec.). The shear force data of four different sizes of chip resistors (1206, 0805, 0603, and 0402) are compared across the different profiles. The shear force of the resistors is measured at time 0 (right after assembly). The fracture surfaces have been studied using a scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS)
