Reflow cycle time calculation
WebThe short answer is yes, but we’ll dive into more detail. There are typically 3 terms used to represent a cycle time, and as we said before, defining those terms varies from manufacturer to manufacturer. 1. Theoretical Max Machine Cycle – Maximum number of parts a machine can produce in a particular time period. 2. WebThe area of the aperture is calculated as follows: Apaste = Vpaste / Stencil (where the Stencil = the stencil thickness.) The Stencil aperture size is calculated as follows: If it is a …

WebAttempts to use such ovens for short reflow profiles (without a soak time) would often overheat single boards, work well with a limited number of boards added at regular intervals, and fail to reflow solder if the oven were fully loaded. With these ovens, longer profiles made for better consistency. With the advent of low mass convection reflow ... WebJan 6, 2024 · I am willing to give you my answer for your question. As to 12 data points per peak, we need to set up the dwell time for each ion (transition) as follows: - the number of cycles per second: 12 : 2.5 = 4.8 cycles/second. - cycle time for 8 components : 1 : 4.8 = 0.208 s = 208 ms.
