摘要
用于高引脚数Quad Flat Pack (QFP)的载波和插座技术(Carrier and Socket Technology)封装由三个组件组成,可以以各种组合方式使用,从而可以更轻松地操作细间距(细间距定义为具有0.65毫米或更小间距的封装),QFP适用于各种运输、测试、编程和原型环境。这三种组件分别是小轮廓托架、面装开发插座和通孔安装编程插座。托架设计用于保护QFP的引线不变形,同时允许引线与两个不同插座的触点进行电气连接。开发插座是表面可安装的,其占地面积与安装在载体内的裸QFP相同。编程插座是一个通孔安装,蛤壳插座,它接受与开发插座相同的载体。
Carrier and socket technology for high pin count QFP packages
The Carrier and Socket Technology for high pin count Quad Flat Pack, QFP, packages is a set of three components, that can be used in various combinations, that allow for easier manipulation of fine pitch, (fine pitch defined as packages having a lead tip to lead tip spacing of .65 millimeters or less), QFP between various shipping, test, programming, and proto- typing environments. The three components are the small outline Carrier, surface mountable Development Socket, and through hole mountable Programming Socket. The Carrier is designed to protect the leads of the QFP from deformation, while allowing the leads to make electrical connection with the contacts of the two different sockets. The Development Socket is surface mountable with a footprint that is identical to the naked QFP housed within the Carrier. The Programming Socket is a through hole mountable, clam-shell socket, which accepts the same Carrier as the Development Socket.<>
