How does BGA rework station work?

Hot air BGA rework stations have several nozzles to guide and circulate the hot air, in order to ensure an even heat distribution. The technicians can direct the air by moving the nozzles, allowing a quick, dedicated work on small components.

Can you solder BGA?

Apply paste flux to the bottom (soldering side) of the BGA package. Carefully place the BGA Package on the solder balls. Preheat and then apply Hot Air with Hot Air Blower from both top and bottom. Solder balls will melt and get soldered.

How do I choose my BGA rework station?

What to consider when choosing BGA Rework Station

  1. Type or Heat Source. There are two basic types of BGA rework stations, hot air and IR or Infrared.
  2. Temperature Control. Another important consideration when choosing a BGA rework station is method for temperature control.
  3. Work Area Size.

What are BGA components?

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package.

What is rework and repair?

Rework – The act of reprocessing non-complying product, through the use of original or alternate equivalent processing, in a manner that assures compliance of the product with applicable drawings or specifications. Repair – Action on a nonconforming product to make it conform to requirements.

Does BGA need solder paste?

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 I check my BGA soldering?

The BGA solder joint bonds are inspected using X-rays. The X-ray inspection helps to look through the device solder joint underneath the components. Due to this ability, the Automated X-ray Inspection (AXI) technology is widely used for BGA inspection.

What is infrared soldering?

IR soldering method is a non-contact soldering method with focused heating area and the soldering process can be done within a few seconds without spreading too much unnecessary heat to the surrounding so as to protect polymer or other low melting temperature or heat sensitive substrates.

How do you inspect a solder joint BGA?
