Edwin,
Standard FR-4 assembly practices apply to GETEK.  It will hold up better in your soldering processes
than standard FR-4.  GETEK has a higher glass transition temperature (Tg=175-185, DMA) than standard
FR-4 and close to but not as high as BT (ranges 170 - 215C depending on the grade).  The CTE of GETEK
and BT are about the same (GETEK ~13ppm/C, BT 13-15 length, 15-17 cross).
You can get additional material properties from GE Electomaterials in Coshocton, Ohio at (740)
