Advanced BGA/CSP/QFN Rework

Explaining step-by-step procedures for BGA,CSP and QFP removal, site preparation and replacement

Today’s rework and repair operations have become a lot more complicated. That’s because surface mount technology has gained increased popularity.

Smaller is a big advantage when it comes to making products more compact. But it makes rework and repair much more difficult. Now, it’s necessary to have excellent vision and incredible dexterity to rework these high density assemblies.

Today, there are component package styles that make it virtually impossible to perform manual rework operations. A couple of examples include ultra fine pitch leaded parts and Ball Grid Arrays, or BGAs. The rework requirements for these types of components have resulted in the development of “rework stations.” Rework stations are self-contained systems that provide controlled removal and replacement of surface mount components.

The training Advanced BGA/CSP/QFN Rework explains step-by-step procedures for BGA,CSP and fine pitch QFP removal, site preparation and replacement. Concludes with a discussion on cleaning and inspection requirements.
