半導體的產品很多，應用的場合非常廣泛，圖一是常見的幾種半導體元件外型。半導體元件一般是以接腳形式或外型來劃分類別，圖一中不同類別的英文縮寫名稱原文為 PDID：Plastic Dual Inline Package SOP：Small Outline Package SOJ：Small Outline J-Lead Package PLCC：Plastic Leaded Chip Carrier QFP：Quad Flat Package PGA：Pin Grid Array BGA：Ball Grid Array 雖然半導體元件的外型種類很多，在電路板上常用的組裝方式有二種，一種是插入電路板的銲孔或腳座，如PDIP、PGA，另一種是貼附在電路板表面的銲墊上，如SOP、SOJ、PLCC、QFP、BGA。 從半導體元件的外觀，只看到從包覆的膠體或陶瓷中伸出的接腳，而半導體元件真正的的核心，是包覆在膠體或陶瓷內一片非常小的晶片，透過伸出的接腳與外部做資訊傳輸。圖二是一片EPROM元件，從上方的玻璃窗可看到內部的晶片，圖三是以顯微鏡將內部的晶片放大，可以看到晶片以多條銲線連接四周的接腳，這些接腳向外延伸並穿出膠體，成為晶片與外界通訊的道路。請注意圖三中有一條銲線從中斷裂，那是使用不當引發過電流而燒毀，致使晶片失去功能，這也是一般晶片遭到損毀而失效的原因之一。 圖四是常見的LED，也就是發光二極體，其內部也是一顆晶片，圖五是以顯微鏡正視LED的頂端，可從透明的膠體中隱約的看到一片方型的晶片及一條金色的銲線，若以LED二支接腳的極性來做分別，晶片是貼附在負極的腳上，經由銲線連接正極的腳。當LED通過正向電流時，晶片會發光而使LED發亮，如圖六所示。 半導體元件的製作分成兩段的製造程序，前一段是先製造元件的核心─晶片，稱為晶圓製造；後一段是將晶中片加以封裝成最後產品，稱為IC封裝製程，又可細分成晶圓切割、黏晶、銲線、封膠、印字、剪切成型等加工步驟，在本章節中將簡介這兩段的製造程序。

SL811開發資料_包含源程序_電路圖_芯片資料:SL811HS Embedded USB Host/Slave Controller.The SL811HS is an Embedded USB Host/Slave Controller capable of communicate with either full-speed or low-speed USB peripherals. The SL811HS can interface to devices such as microprocessors, microcontrollers, DSPs, or directly to a variety of buses such as ISA, PCMCIA, and others. The SL811HS USB Host Controller conforms to USB Specification 1.1.The SL811HS USB Host/Slave Controller incorporates USB Serial Interface functionality along with internal full-/low-speed transceivers.The SL811HS supports and operates in USB full-speed mode at 12 Mbps, or at low-speed 1.5-Mbps mode.The SL811HS data port and microprocessor interface provide an 8-bit data path I/O or DMA bidirectional, with interrupt support to allow easy interface to standard microprocessors or microcontrollers such as Motorola or Intel CPUs and many others. Internally,the SL811HS contains a 256-byte RAM data buffer which is used for control registers and data buffer.The available package types offered are a 28-pin PLCC (SL811HS) and a 48-pin TQFP package (SL811HST-AC). Both packages operate at 3.3 VDC. The I/O interface logic is 5V-tolerant.

Lachesis an IRCRPG combat engine written in a combination of C and C++. The combat engine is being written for a specific RPG, but most of the project should be useful to IRCRPGs in general. It includes a native interface to the IRC protocol to allow it to act as an IRC bot, for such uses as dice rolling and acting as a remote-controlled client (RPG NPC perhaps).

WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.

Client/Server版本 DBISAM compiles directly into your application with no external libraries required. Runtime package support is also provided if so desired. It has a very small footprint and does not require any forms support in Delphi 6, C++Builder 6, and Kylix 2 and higher, which helps keep the size of non-UI applications like services or web applications to a minimum.
