Hi,
On one of my PCBs i'm using a heavy IC. It is a 70pin gull wing
package. And, the problem is that the pins are breaking near the IC
package. I don't want to use RTV, as it's difficult to remove. What
best I can do to protect this against vibration tests?

Thanks and Regards,
Veeresh

Can you link to a package drawing?

Best regards,
Spehro Pefhany

Hello Sir,
Thanks for the kind response from all of you.

It has passed the tests some times. But when tested for many times,
the pins break. I want to make it rugged... exactly option (b) :-)
The PCB is housed in an enclosure with screws at every 5cm w.r.t each
other. Please check the link below for package diagram.

please consider the data *** of BU-61580(second one ). I'm using the
gull wing package - page 44 of 46. I took this perticularly to save
the space.
Now, I've kept a sil pad below the device, super glue on four corners,
and RTV on pins. Is this fine, or something better can be done?

Regards,
Veeresh

Have you considered asking the manufacturer? Why don't you tell us
how much it costs so Joerg can have a heart attack? Last part I used
from that company was in the high four digits (USD).

US$ 1000 :-)
