The solder balls provide a minimal gap of .5mm to .7mm. Attachment feature is below a .4mm thickness. The clipping system will not interfere or damage chip. Contact area is the edge of chip. ASSEMBLY INSTRUCTION: Step 1: Hook the clip under one side of the BGA chip set. Step 2: Rotate assembly down until opposite side clip engages substrate edge of BGA chip set. Random Vibration Test Frequency ：5 Hz to 500 Hz Acceleration ：3.13 grms P.S.D ：0.01 g2/HZ (5 Hz) 0.02 g2/HZ (20 Hz to 500 Hz) Test Axis ：X, Y, Z axis Test Time ：10 mins (Each axis) Total Test Time ：30 mins T h e r m a l C o o l i n g S o l u t i o n s Step 3: Make sure the sop rods are clearing from edges of BGA chip set. Step 4: Press firmly down to make sure clips fully engage edges of chip set. Heat Sink should not move around easily. SHOCK TEST SPECIFICATION： Wave Form ：Half sine wave Acceleration ：50 g Duration Time ：11 ms No. of Shock ：Each axis 3 times Shock Direction ：±X, ±Y, ±Z axis Reliability & Communication Testing Instruments f r o m S m a r t www.wakefield-vette.com t o F i n i s h
