Ball grid array (BGA) to column grid array (CGA) conversion process

摘要

A method of converting ball grid array (BGA) modules to column grid array (CGA) modules comprises steps of heating a BGA module, brushing the BGA module to remove the balls, and attaching columns to the module to create a CGA module. A method of converting a first CGA module to a second CGA module comprises steps of heating the first CGA module, brushing the first CGA module to remove the columns, and attaching columns to the module to create the second CGA module.
