PCN Details
Description of Change:
Silicon Laboratories, Inc (Silicon Labs) is pleased to announce the successful qualification of United
Test and Assembly Center Ltd, Thailand (UTAC-TH) as the new assembly site and test site for the
20-QFN-4x4, SL38007 clock generator product family. The existing assembly and test provider,
Mitsui-Japan (MHT) no longer supports Silicon Labs SL38007 families.
UTAC-TH is an existing assembly site and test site for Silicon Labs and is certified and registered to
ISO9001, ISO14001, ISO/TS16949 and is a Sony Green Partner.
1. Assembly Site Change:
UTAC-TH is an existing assembly supplier for Silicon Labs. UTAC-TH is a fully qualified supplier for
the SL38007 part family in the 20-pin QFN-4x4. UTAC-TH is in Thailand, and is part of the UTAC
Group.

Reason for Change:
Silicon labs exited MHT due to costly governmental taxing policies for value-added goods shipped
within Japan, and consolidated assembly and test site of clock generator product family to UTACTH.
Impact on Form, Fit, Function, Quality, Reliability:
There is no impact on form, function, quality or reliability. The SL38007 clock generators
manufactured/assembled or tested at UTAC-TH fully comply with datasheet parameters and quality
levels.
The fit of the product has slightly changed. There is a minor difference for the bottom E-pad size
between the UTAC-TH 4x4 QFN package and MHT package.
