Ah, see Steve, I was right. It depends Marcin. If you use the same temps in each zone for all your product, vary you converyor speed. This will negate any waiting time between profiles. Slowing the speed will decrease your Delta-T to an acceptabl

Ramp rate is measured in degrees per second. Max and min temps are not required to to establish "ramp rate". The difference between parts, like I was describing is Delta T. But, ramp rate is a generation from this as well. Most component manufact

Though today's microvias and high aspect plated through holes (PTH's) look nothing like the earliest through holes of 40 years ago, the PTH in its various forms remains the “weak link” and most critical element of printed wiring boards and laminate chip carriers (...) The paper outlines an approach to evaluating PTH reliability and quality that involves characterizing PTH life across a range of temperatures to reveal intricacies not seen by testing at a single delta-T, and certainly difficult to predict by modeling alone.
