IPC TM-650 2.6.10A
X-Ray (Radiography), Multilayer Printed Wiring Printed Board Test Methods
Organization:
IPC - Association Connecting Electronics Industries
Year: 1997
Abstract: This non-destructive inspection method is needed to ascertain the following conditions:
a. Innerlayer shift is within acceptable tolerances.
b. One or more inner layers have not been reversed.
c. Drilled holes are aligned with pads to the extent that any break-out is within acceptable tolerances.
d. The minimum distance between a drilled hole and a ground plane clearance is within acceptable tolerances.
The test method will entail passing X-rays through the test specimen and converting the transmitted X-ray image into a visual image through the use of either X-ray film or a flouro- scopic (real time) device.
Cautionary notes:
The construction of the multilayer with respect to; number of layers, thickness of copper and presence other metals such as heat sinks (e.g. Invar), will determine the power and sensitivity of the X-ray apparatus which can be used. All X-ray apparatus should be registered with the appropriate state or regional Radiation Control agency.
A radiation safety program should be implemented.
