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.
