Consensus for Baking Prior to Rework?
Consensus for Baking Prior to Rework?
What is the industry consensus for baking out moisture in circuit board assemblies prior to convection rework, localized mini-wave rework, or hand soldering rework? The Assembly Brothers, Phil Zarrow and Jim Hall, discuss this.

Solder Paste Volume for BGA Rework
Solder Paste Volume for BGA Rework
Since rework can never be as controlled or consistent as original assembly, should we use slightly more paste during BGA rework to compensate for irregularities or flatness, pad conditions and so forth? The Assembly Brothers, Jim Hall and Phil Zarrow, answer this question.
