PCB LAYOUT
In making the pad size for the BGA balls, it is
recommended that the layout use solder-mask-defined
(SMD) land. With this method, the copper pad is made
larger than the desired land area, and the opening size is
defined by the opening in the solder mask material. The
advantages normally associated with this technique
include more closely controlled size and better copper
adhesion to the laminate. Increased copper also increases
the thermal performance of the IC. Better size control is
the result of photo imaging the stencils for masks. Small
plated vias should be placed near the center ball
connecting ball B2 to the ground plane. Added plated vias
and ground plane act as a heatsink and increase the
thermal performance of the device. Figure 35 shows the
appropriate diameters for a 2mm X 2mm MicroStar
Junior
BGA layout.
It is very important to keep the TPA6203A1 external
components very close to the TPA6203A1 to limit noise
pickup. The TPA6203A1 evaluation module (EVM) layout
is shown in the next section as a layout example.
