Why Do Our Boards Warp During Reflow?
Why Do Our Boards Warp During Reflow?
Board flexing has recently started to occur on one of our circuit board assemblies, yet our process has remained the same. We are using a three-zone reflow oven. Phil Zarrow and Jim Hall, The Assembly Brothers, discuss this.

5 vs 8-Zone Ovens
5 vs 8-Zone Ovens
We are setting up an assembly line for small line production. We prefer to purchase a 5-zone oven but our concern is that five zones may not be enough to ensure a reliable reflow process compared to an 8-zone oven. Jim Hall and Phil Zarrow, The Assembly Brothers, share their insight.
