1. Feasibility Study and Information collection for quotation Miley Combo and Main Antenna Based on files received on 2009-06-15 Version: 2

2. Miley_Feasibility_study / Peter Karlsson2 Part Name: Combined Antenna Part 3D Version: XXXX Material:PC/ABS Decoration: Weight / Vol. Secondary Operations: Main Technologies: General Part Information Major Risks Identified

3. Miley_Feasibility_study / Peter Karlsson3 Combo Antenna LOM Suggestion Risks identified Guiding features missing. With good guiding one of the parts can be placed with ±0.2-0.3mm. Suggest to add guide holes in the flex. Risk for peal off. Pressure jigs needed. The plastic antenna carrier must be single bended surface to be able to assembly the antenna. Simplified surfaces on the carrier is needed. Assembly –Antenna type: GPS WL BT Antenna, flex film –Assembly Method: Adhesive Manual using jig. –Guiding: No guiding in current design. Guiding features is needed –Parts effecting the antenna: Side Panel (SUS) Flash PBA Camera 3.5 mm AV-Connector D-Cover Insert –Type of antenna connection: Not included in file. Probably some type of leaf spring connector Antenna Carrier Antenna flex Guide hole in flex and carrier Simple surface

4. Miley_Feasibility_study / Peter Karlsson4 GPS WL BT Antenna Risks identified Antennas electrical concept NOT described Antenna product specific specification not received from Nokia –LOM is following Nokia generic antenna specification Assembly tolerance impact to RF variation not known Based on experience, for BT/WLAN antenna, 0.1mm shift on positioning gives 5-10MHz frequency variation –With +/-0.5mm ( manual assembly tolerance +/-0.3 and +/-0.2mm copper outline tolerance) shift the variation could in worst case be +/-50Mhz –100%RF Testing implemented Based on experience, for GPS antenna, 0.1mm shift on positioning gives 3-6MHz frequency variation –With +/-0.5mm ( manual assembly tolerance +/-0.3 and +/-0.2mm copper outline tolerance) shift the variation could in worst case be +/-30Mhz –100%RF Testing implemented No IPR issues identified based on current information Material –Antenna typ: Flex Antenna –Total thickness: ~0,15 mm –Effective area: 272 mm 2 –Cosmetic class: 3 Not Visible. –SMT Components (soldering): No –Build-up (No soldering): 1.Solder Mask, 12-18 µm Cosmetic class 3 2.Copper (RA), ~ 18 µm 3.Adhesive ~ 8,5 µm 4.Pet ( Polyester), 50 µm 5.Adhesive 3M 467, 60 µm 6.Pet Liner –Roller direction: See picture. –Number of contact points: Two contact points –Plated area: 3.2 x 5,9 = 18,9mm 2 –Plating: Ni 3 ± 1 µm Au > 0.5 µm –Tolerance: Cu to Cu ± 0.05 Cu to Outline ± 0.2 Outline ± 0.1 Contact area Plated Area Roller direction
