The XR 3500/3700 Real Time Inspection System is a 
powerful tool in the quality control and process verification 
of all aspects of microelectronics manufacturing.  The XR 
3500/3700 provides rapid, real-time x-ray inspection for 
production and rework environments.  Its self-contained 
console design supports easy customizing for numerous 
applications, including multi-layer PCBs, small hole 
drilling, large back-planes and assemblies with advanced 
components, such as BGAs, 

BGAs and chip-scale 

packages. 

 
 

In bare board applications, it can be used to check for 
interlayer shift and drilled hole-to-pad offset.  Inspection is 
performed following lamination, to determine the  
presence and degree of interlayer shifts.  At the onset of 
either conventional or small hole drilling, inspection is 
used to qualify hole-to-pad alignment.  In addition to 
enhancing product quality, x-ray inspection enables users 
to control costs by eliminating defective boards early in 
the production process.  It can also be used to quality 
control incoming boards from vendors or customers so 
that defects can be detected before problems occur. 

 

For surface mount components, it is used to verify 
lead/pad coplanarity, shorts, opens, and solder bond 
quality.  It can be used to check resistors and capacitors 
as well as 

IC’s for internal damage and verify adjustments 

throughout the placement and reflow processes. 

 

 
 

For 

BGA’s, the XR 3500/3700 can be used to check for 

all potential defects including:  shorts, opens, mis- 
registration, non-wetting, solder ball voids, and 
delamination.  X-ray is used to verify proper reflow 
profiles for advanced packages, and to control rework 
process.
