<< As a contract manufacturer, we recently have asked if we had any

      Does anyone have any assembly experience regarding "localized heat" or

      Is there any other properties that I should be aware of when I am
      assembling components on these boards? (Board bowing, hydroscopic
      properties that limit the board from going through the wash)
 
      Thank you for any input

Hi Rob!

Go to: http://www.ge.com/electromaterials/products.htm#getek and you'll find 
some info about it. Looks to me like you would handle Getek boards the same 
way as any
other board. Looks to me like it's just a different high Tg laminate. Heck I 
may have built some boards that were Getek and didn't know it...below I 
pasted some stuff from the page...

Overview 

GE Electromaterials manufactures and supplies laminates and prepregs for the 
printed circuit board industry. Our materials offer a cost effective and 
efficient option to meeting your demands.
 
GETEK® Thin Laminates (ML200), Rigid Laminates (RG200) and Prepregs 
(T-Series)  

GETEK® laminates and prepregs are patented products composed of epoxy and 
polyphenylene oxide (PPO®) resins. They offer the improved thermal and 
electrical properties needed for sophisticated circuitry - along with 
processability and significant cost savings. GETEK® materials can easily 
replace BT/Epoxy, Cyanate Ester, Polyimides, PTFE (Teflon®), and other 
substrates in many existing applications.
 
Benefits: 

Performance:
• Low and stable dielectric constant and dissipation factors
• Low moisture absorption
• High UL maximum operating temperature
• High Tg
• Low Z-axis expansion
• Superior crack resistance during thermal cycling

Processability: 

• Better dimensional stability 
• Tighter thickness control 
• Consistent results of one formulation 
• Processable with modified FR4 methodology 
• Superior craze resistance 
• Naturally UV-blocking; Fluorescent for AOI
 
The Result: 
 
Performance that matches higher-priced materials, easier processing than 
conventional high performance products and low material cost. It adds up to 
make GETEK® laminates the most cost efficient solution for high-end 
applications involving impedance control, high frequency and burn-in boards.
