Customer Notification

Tin Lead Plating Phase Out for Leadframe Products

Rev. 12/98

Page 1 of 2

Dear Valued Customer:

This notification is for the purpose of informing you that our supplier, Amkor Korea, will phase out all Tin Lead

plating by the end of 2010 for leadframe based products listed below. All parts affected by this notification will now

be assembled using Matte Tin plating.

Purpose

The purpose of the change at our supplier is to standardize their process to the Pb-free industry trend and in

alignment with decreasing Tin Lead customer demand. This standardization will bring them in line with green

environment (Pb-free) initiatives, eliminate a low efficiency process and provide better, more stable quality and

service.

Customer Impact

No customer impact is anticipated with this notification; Amkor has performed backward compatibility testing to

assure that parts assembled with Matte Tin finish will pass solderability tests using the Tin Lead eutectic solder

reflow profile.

We are confident this notification will allow Mindspeed Technologies to maintain its high standards for quality and

reliability. If, at any time, you have a need for further information, please contact your local Sales Representative.
