What is BGA in SMT?

What is BGA in SMT?

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.

Which is the second stage in the reflow soldering process?

The second section, thermal soak, is typically a 60 to 120 second exposure for removal of solder paste volatiles and activation of the fluxes, where the flux components begin oxide reduction on component leads and pads.

How many types of BGA are there?

Technically, these package types fall into three main categories: Ceramic BGA (CBGA) Plastic laminate BGA (PBGA) Tape BGA (TBGA)

How is reflow soldering technology used for BGA?

Due to particularity of BGA package components, this article will discuss reflow soldering technology with PBGA as an example. Preheating phase is usually composed by 2 to 4 heating zones with temperature constantly going up to 150°C within 2 minutes so that volatile substances in solder paste can be volatilized out.

How does the preheating phase of BGA work?

Preheating phase is usually composed by 2 to 4 heating zones with temperature constantly going up to 150°C within 2 minutes so that volatile substances in solder paste can be volatilized out. As a result, those substances won’t lead solder to be splashed or base to be over-heated.

What kind of Assembly is used for BGA?

BGA is a type of package accepted by SMT (surface mount technology) assembly, applied by multi-pin LSI (large scale integration). Up to now, BGA package can be classified into three categories in accordance with base types: PBGA (plastic ball grid array), CBGA (ceramic ball grid array), TBGA (tape ball grid array).

What does BGA stand for in baseball terminology?

BGA, short for Ball Grid Array, takes advantage of solder balls that play a role as pins at the back of base. BGA is a type of package accepted by SMT (surface mount technology) assembly, applied by multi-pin LSI (large scale integration).
