Array Rework Services
PSI has over 12 years experience reworking & reballing array
devices. Specialty rework equipment conceptualized by, and manufactured
for PSI, allows quick & accurate profiling of all assemblies up to
24" x 24" and 0.25" thick. Our real-time X-Ray equipment provides 160
KeV of power to see through virtually any product with remarkable
resolution. PSI will rework quantities ranging from one part/ assembly
to thousands of parts/ assemblies.
PSI reworks:
- Ceramic Column Grid Arrays (CCGA)
- Ceramic Ball Grid Arrays (CBGA)
- BGA interposer modules/ sockets/ connectors
- Plastic & Metal top BGA's up to 2.5"x 2.5"
- Micro BGA's down to .5 mm pitch
- Lead-free BGA's
PSI Reballs:
- High-temp solder spheres
- Eutectic Tin/ Lead solder spheres
- Lead-free solder spheres
- BGA modules/ sockets/ connectors
BGA Sockets / Connectors
A wide variety of BGA connectors and
sockets are in use today. PSI has developed processes for successful
removal/ replacement & reballing of a myriad of connectors and
sockets.
Ceramic Ball or Column Grid Arrays
PSI can remove & replace ceramic
array devises on small or large assemblies. Parts with up to 1752
solder connections on 1mm centers are routinely reworked. PSI will
reball your ceramic parts with high-temp solder spheres. We do not
offer re-columning services.

BGA Interposer Modules
BGA interposer modules can have many
different configurations. Some are used to configure a BGA part that
can be plugged into a pin grid array socket. Other modules combine
functions on a small circuit card, and adapt to a BGA footprint on a
mother assembly. PSI has helped pioneer the processes used for
developing and reworking these modules.
PSI can provide the following services for BGA interposer modules:
Sphere attach to circuit laminate
- High temp solder spheres
- Eutectic tin / lead solder spheres
- Lead-free solder spheres
Manufacturing / reowrk process development
- Material selection
- Process flow for manufacturing
- Rework profile development
- Failure analysis or product qualification services are provided in our analytical laboratory
