data sheet W A F E R L E V E L PAC K AG I N G CSPnl™ Features: Wafer Level Packaging CSPnl™ Amkor's wafer level packaging service meets the industry's growing demand for full turnkey assembly and test solutions for CSP (Chip Scale Package) products. Through the acquisition of Unitive, Amkor has adopted the CSPnl™ as its standard wafer level package offering. CSPnl™ represents the next level in wafer level chip scale packaging as demonstrated by its proven benchmark reliability. Amkor's CSPnl™ has been widely adopted as the industry standard for cost effective, reliable, high performance wafer level CSP applications. By integrating our CSPnl™ packaging technology with existing die processing and testing services as well as new die processing technologies developed by Unitive, Amkor is able to offer a full turnkey solution for wafer level products. CSP ™ is a true wafer level CSP package that can incorporate thin film redistribution films to route I/O pads to JEDEC/EIAJ standard pitches, and thereby, avoiding the need to redesign legacy parts for CSP applications. It is available in three options: Direct Bump on Pad (BOP), Bump on Repassivation/Redistribution and Bump on Thick Repassivation/Redistribution. The technology used for CSPnl™ results in robust packages that do not require underfill in their applications. CSPnl™ is designed to utilize industry-standard surface mount assembly and reflow techniques. By using conventional SMT placement equipment and avoiding the need for underfill, the end-user experiences many of the cost benefits associated with other JEDEC standard area array packages. Package Options: Reliability: nl Amkor's wafer bumping and test offering is an excellent complement to other Amkor product lines. Through an integrated die processing service, Amkor is able to provide full turnkey wafer bumping, test, die singulation, and tape & reel support for wafer level packaging applications. In addition, Amkor is able to integrate its wafer bumping products into high performance packaging options, such as Flip Chip CSP (fcCSP) and System in Package (SiP). Amkor truly provides one-stop, hassle-free support for wafer bumping, packaging, and test solutions, enabling you to meet your cost and time-to-market objectives. • 4-64 ball count • 0.8 mm - 4.5 mm body size • Repassivation, Redistribution and Bumping options available • Electroplated and Ball-loaded bumping options • Eutectic, High Lead and Lead-free solder • Standard JEDEC/EIAJ pitches and CSP solder ball diameters • Compatible with conventional SMT assembly and test techniques • Back-side laser mark compatible • Back-side laminate • Impressive component and board level reliability • Cost effective packaging solution for small ICs • No need for underfill • Full turnkey bumping, test and TnR support • Ship to customer in either wafer form or singulated form Ball Loading: Pitch 0.40 mm 0.50 mm 0.65 mm 0.75 mm Sphere Diameter 0.25 mm 0.30 mm, 0.35 mm 0.35 mm 0.50 mm Package Level: • Autoclave (PCT) 121°C/100% RH/15 psig, 96 hours • Temp Cycle -55°C/+125°C, 500 cycles • High Temp storage 170°C, 420 hours Second Level Reliability (BLR): • HAST 130°C/85%RH/33.5psia/Biased, 96 hours • HTOL 150°C/Biased, 300 hours • Temp Cycle -40°C/+125°C, 1000 cycles • Key Push 100cycles/min, 2.7mm max displacement • Bend Test Strain rate 5mm/min, 85mm span • Drop Test 50cm height Applications: Amkor's CSPnl™ is ideal for portable communications and related applications that require a low cost packaging solution with small form factor and improved signal propagation characteristics.
