Contact Resistance: Operating Temperature Range: –55°C to +150°C –40°C to +170°C 30g per pin approx. Contact Force: 10,000 insetions Mating Cycles: NP276 Materials and Finish Design Number - 1105 22 - * - (*) Series No. No. of Contact Pins (.AC-types are depopulated base sockets) Housing: Polyetherimide (PEI), glass-filled Polyethersulphone (PES), glass-filled Positioning Pin Options (see PCB): Pos. pin 'A' Pos. pin 'B' 1= With With 2= With Without 3= Without With 4= Without Without Contacts: Beryllium Copper (BeCu) Plating: Gold over Nickel Features í Open top type sockets for BGA packages í Self contacting structure without upper pressing force (ZIF) í Contacting structure to nip the sides of solder balls to lower damage to the coplanarity of the solder balls Contact Terminal Length and Form Yamaichi's 2-point Tweezer Contact IC Ball Socket Base A Since the solder balls are touched by two contacts on each side, the solder ball damage can be minimized; additional features are low actuation force and compact socket size Contacts Socket Base B We have depopulated versions from existing NP276 base sockets. As new versions are continually being tooled up we rcommend to contact Yamaichi for your specific pin count and matching IC Applicable Base Socket and IC Dimensions Part Number NP276-11904 NP276-11904-3 NP276-15316 NP276-16951 NP276-25626 NP276-37206 NP276-40009 NP276-59608 NP276-65227 NP276-87318 NP276-110522 Test & Burn-In Pin Count 119 119 153 169 256 372 400 596 652 873 1105 IC Dimensions Pitch 1.27 1.27 1.27 1.27 1.27 1.27 1.27 1.27 1.27 1.27 1.27 Grid Size 7 x 17 7 x 17 9 x 17 13 x 13 16 x 16 20 x 20 20 x 20 26 x 26 28 x 28 31 x 31 35 x 35 Body Size 14 x 22 14 x 22 14 x 22 17 x 17 21 x 21 27 x 27 27 x 27 35 x 35 37.5 x 37.5 40 x 40 45 x 45 SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Base Sockets (see page) 2 2 3 4 5 6 7 8 9 10 11 NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-11904 Outline Socket Dimensions (27.00 x 38.00mm) Grid Size: 7 x 17 NP276-11904 Pin Count 119 Body Size 14 x 22 Base Socket NP276-11094-3 Outline Socket Dimensions (26.40 x 32.20mm) Grid Size: 7 x 17 3.80 NP276-11094-3 Pin Count 119 Body Size 14 x 22 SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Test & Burn-In NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-15316 Outline Socket Dimensions (28.40 x 33.20mm) 3.80 = NP276-15316 Grid Size: 9 x 17 NP276-15316 Test & Burn-In Pin Count 153 Body Size 14 x 22 SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-16951 Outline Socket Dimensions (27.00 x 38.00mm) Pin Count 169 Body Size 17.0 x 17.0 Grid Size 13 x 13 SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Test & Burn-In NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-25626 Outline Socket Dimensions (49.4 x 49.4mm) 49.40 Pin Count 256 Body Size 21.0 x 21.0 Grid Size 16 x 16 Recommended PC Board Layouts Top View from Socket Various Pin Counts Test & Burn-In SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-37206 Outline Socket Dimensions (49.4 x 49.4mm) 49.40 Pin Count 372 Body Size 27.0 x 27.0 Grid Size 20 x 20 Recommended PC Board Layouts Top View from Socket Various Pin Counts SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Test & Burn-In NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-40009 Outline Socket Dimensions (49.4 x 49.4mm) 49.40 Pin Count 400 Body Size 27.0 x 27.0 Grid Size 20 x 20 Recommended PC Board Layouts Top View from Socket Various Pin Counts Test & Burn-In SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-59608 Outline Socket Dimensions (58.4 x 58.4mm) 58.40 Pin Count 596 Body Size 35.0 x 35.0 Grid Size 26 x 26 Recommended PC Board Layouts Top View from Socket Various Various Pins Pin Counts SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Test & Burn-In NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-62525 Outline Socket Dimensions (58.4 x 58.4mm) 58.40 Pin Count 625 Body Size 35.0 x 35.0 Grid Size 25 x 25 Recommended PC Board Layouts Top View from Socket Various Pins Various Pin Counts Test & Burn-In SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-87318 Outline Socket Dimensions (68.0 x 68.0mm) 68.00 Pin Count 873 Body Size 42.0 x 42.0 Grid Size 35 x 35 Recommended PC Board Layouts Top View from Socket Various Pin Counts SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER Test & Burn-In NP276 Series (Open Top) Ball Grid Array Base Socket (BGA, 1.27mm Pitch) Base Socket NP276-110522 Outline Socket Dimensions (74.0 x 74.0mm) 74.40 Pin Count 1105 Body Size 45.0 x 45.0 Grid Size 35 x 35 Recommended PC Board Layouts Top View from Socket Various Pin Counts Test & Burn-In SPECIFICATIONS ARE SUBJECT TO ALTERATION WITHOUT PRIOR NOTICE – DIMENSIONS IN MILLIMETER
