1 Reliability Laboratory Page: 1 of 7 Date: August 31, 2007 TEMWELL CORPORATION 8F-1, NO. 51, SEC. 1, MIN SHENG E. RD., TAIPEI, TAIWAN The following merchandise was submitted and identified by the vendor as: Product Description: TEMWELL BRAND Helical Filter Style/Item No.: 7H/ No.1~ No.5 Manufacturer/Vendor: TEMWELL CORPORATION Quantity: Total 5 pieces Testing Period: Aug. 28, 2007 to Aug. 29, 2007 Note: (Client s declaration) The materials used for 7H series are similar. We have tested the submitted sample(s) as requested and the following results were obtained: Test Required: (According to client s test specification, please see following sheets in detail.) Solderability Test by Solder Bath/ Dip and Look Test (Leads, Wires, etc.) According to client s test specification, the test procedures are shown as below. Test Procedure Identification Test Action/ Item Test Sequence Preconditioning 1 Solder Bath / Dip and Look Test 2 Test Object: The test purpose is to verify that the solderability of component leads and terminations meets the requirements provided by client and that subsequent storage has had no adverse effect on the ability to solder components to an interconnecting substrate. Test Results: - PLEASE SEE ATTACHED SHEETS - Terence Hsieh Asst. Manager

Solder Bath/ Dip and Look Test (Leads, Wires, etc.) Test Method: IPC/EIA/JEDEC J-STD-002B Clause Type of Flux: Unactivated Solder Composition: 60Sn/40Pb Test Temperature: 235±5 Immersion Angle: See below item marked, Between 20 o and 45 o 90 o Immersion Speed: 25±6 mm/s Withdraw Speed: 25±6 mm/s Immersion Depth: Within 1.25 mm of the component body or to the seating plane (whichever is further from the component body) Dwell Time: 5 +0/-0.5 seconds * Leads should be immersed in the flux for 5 to 10 seconds before soldering. * Before examination, all leads shall have all visible flux residues removed by alcohol. Test Requirement: All leads shall exhibit a continuous solder coating free from defects for a minimum of 95% of the criteria area of any individual lead. Anomalies other than dewetting, nonwetting, and pin holes are not cause for rejection.
