Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor devices. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the device. Feature sizes are constantly shrinking, resulting in increased number of transistors being packed into the device. Today's submicron technology is also enabling large-scale functional integration and system-on-a-chip solutions. In order to keep pace with these new advancements in silicon technologies, semiconductor packages have also evolved to provide improved device functionality and performance. Feature size at the device level is driving package feature sizes down to the design rules of the early transistors. To meet these demands, electronic packages must be flexible to address high pin counts, reduced pitch and form factor requirements. At the same time,packages must be reliable and cost effective.

This application note contains a reference design consisting of HDL IP and Xilinx AdvancedConfiguration Environment (ACE) software utilities that give designers great flexibility increating in-system programming (ISP) solutions. In-system programming support allowsdesigners to revise existing designs, package the new bitstream programming files with theprovided software utilities, and update the remote system through the JTAG interface using theEmbedded JTAG ACE Player.

The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the right package has becomeone of the key considerations for the systemdesigner.

The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.

第一步，拿到一塊PCB，首先在紙上記錄好所有元氣件的型號，參數，以及位置，尤其是二極管，三機管的方向，IC缺口的方向。最好用數碼相機拍兩張元氣件位置的照片。第二步，拆掉所有器件，并且將PAD孔里的錫去掉。用酒精將PCB清洗干凈，然后放入掃描儀內，啟動POHTOSHOP，用彩色方式將絲印面掃入，并打印出來備用。第三步，用水紗紙將TOP LAYER 和BOTTOM LAYER兩層輕微打磨，打磨到銅膜發亮，放入掃描儀，啟動PHOTOSHOP，用彩色方式將兩層分別掃入。注意，PCB在掃描儀內擺放一定要橫平樹直，否則掃描的圖象就無法使用。第四步，調整畫布的對比度，明暗度，使有銅膜的部分和沒有銅膜的部分對比強烈，然后將次圖轉為黑白色，檢查線條是否清晰，如果不清晰，則重復本步驟。如果清晰，將圖存為黑白BMP格式文件TOP.BMP和BOT.BMP。第五步，將兩個BMP格式的文件分別轉為PROTEL格式文件，在PROTEL中調入兩層，如過兩層的PAD和VIA的位置基本重合，表明前幾個步驟做的很好，如果有偏差，則重復第三步。第六，將TOP。BMP轉化為TOP。PCB，注意要轉化到SILK層，就是黃色的那層，然后你在TOP層描線就是了，并且根據第二步的圖紙放置器件。畫完后將SILK層刪掉。 第七步，將BOT。BMP轉化為BOT。PCB，注意要轉化到SILK層，就是黃色的那層，然后你在BOT層描線就是了。畫完后將SILK層刪掉。第八步，在PROTEL中將TOP。PCB和BOT。PCB調入，合為一個圖就OK了。第九步，用激光打印機將TOP LAYER， BOTTOM LAYER分別打印到透明膠片上（1：1的比例），把膠片放到那塊PCB上，比較一下是否有誤，如果沒錯，你就大功告成了。
