Do I need solder paste for BGA?

In most cases BGA rework can be achieved, and is often more reliable, without addition of solder paste (i.e., using only the solder balls). This assumes a good site prep and proper flux process. In cases where there may be planarity issues, solder paste can be beneficial.

How do you clean a BGA chip?

“We currently clean reballed BGA components using an ultrasonic cleaner with hot water and a cleaning solution. The components are then baked at 100 to 120 degrees C to remove any moisture. The components appear very clean after this process.

What is BGA soldering?

What is a BGA? A Ball Grid Array Integrated Circuit is a surface mount device (SMD) component that possesses no leads. This SMD package employs an array of metal spheres that are made of solder called the solder balls for connections to the PCB (Printed Circuit Board).

What is BGA in soldering?

What is the BGA rework process?

The BGA rework process can be methodically worked out by following these process guidelines even with differences in printed circuit boards as well as devices populated on those boards. Years of experience, varied equipment , the right tools and fixturing and a robust BGA rework process all help to insure high expected yields.

What are the different types of BGA rework stations?

Original equipment manufacturers and PCB contract manufacturers typically use two different types of BGA rework stations: hot air or infrared (IR). What is the difference between these two types of BGA rework machine, and is one better than the other?

What is the sp-360c BGA rework station?

The SP-360C BGA Rework Station is a basic rework station that is ideal for entry-level circuit board repair jobs. This rework station does not have a split-vision assist camera.

What are some of the common mistakes in BGA rework?

Some of the BGA rework mistakes that can be avoided due to proper material choices and proper equipment selection includes solder joints voided by excessive solder.
