WebYou can expect the solder balls of a BGA package to shrink by about a third after reflow.For example, if the solder balls have a height of 0.3mm before reflow, they will shrink to a … WebThe solder fillet (height) of a surface can be identified in the color map, and detailed data can be acquired by profile measurement of the desired cross-section. By switching the magnification, it is possible to measure the entire shape or detailed parts of small and delicate mounted components with high accuracy and by non-contact means.
Instantaneously and Accurately Measuring Solder Fillet Shapes
Webconsistent solder paste deposit heights between pads via a vision system designed to measure solder paste deposition height, 4) avoiding inefficient tack force by avoiding extreme environmental conditions, 5) minimizing the amount of movement the assembly sees during reflow, and 6) increasing component placement WebOct 18, 2024 · The optimum fillet ranges in height from about 1/3 to 2/3 of the part termination height. This does not mean that all solder joints outside of this range should be repaired. It does mean that this is the target for the process engineer to reach for in his process. As many as possible of the solder fillets on the board should be in this range. earth to mars weight

The diameter variation range is about 5%, however, the solder … WebMay 21, 2024 · 3D inspection is designed to verify both the height and footprint of solder paste targets before you insert the parts to be soldered into place. The data from 3D solder paste inspection may allow for part placement that compensates for warpage. Or you may have the solder paste repaired or redone rather than having a defective solder joint. earth to moon distance km
