BEST Installs Cold Component Removal System

Reading time ( words)

BEST Inc. is pleased to announce the installation of a high-precision milling center the AVX1000M from Air-Vac Engineering.

This milling system allows BEST to remove components using a cold rework process. This process capability replaces the high-temperature desoldering process with a high-precision milling process design for PCBs. This cold removal technique increases PCB rework yields as underfilled components do not have solder pushed around during the removal process thus causing soldering failures. The cold component removal is also appropriate in cases where the components to be removed are very close to heat-sensitive components or where a hot soldering iron may not be easily squeezed into tight spaces.

The AVX1000M is designed for high-end PCB rework. The milling system features precision laser measuring and alignment controls for removing the entire component to within a few thousandths of the PCB surface. The milling center also has vibration control including an integrated vacuum fixture. The machine has a built-in vacuum system to prevent debris from contaminating the PCB during the milling operation. 

Dan Patten, BEST general manager stated “With this service capability BEST can now service customers requiring high volume rework of underfilled PCBs. This is going to be beneficial for automotive, consumer and military customers with handheld device using underfill.”
