2023年3月13日 · WLCSP （Wafer Level Chip Scale Packaging）即 晶圆级芯片封装 方式，不同于传统的芯片封装方式（先切割再封测，而封装后至少增加原芯片20%的体积），此种最新技术是先在整片晶圆上进行封装和测试，然后才切割成一个个的 IC颗粒 ，因此封装后的体积即等同IC裸 …

WLCSP is a true die-scale package and offers the smallest footprint for each I/O count of any standard IC package such as QFN or Chip Array BGA. For example, the footprint of a 32-pin QFN package for one of Cypress’s touchscreen products is 25 mm2 (5.0 × 5.0 mm), while the equivalent WLCSP (Figure 1) with 30 balls is only 5.1 mm2 (2.2 × 2.32 mm).

2018年11月22日 · The WLCSP (Wafer Level Chip Scale Product) is a whole new package technique for power switches and space limited application demands. This product is mainly optimized by the increase of utilization ratio on a package and …

2020年7月22日 · To meet the urgent market demand for small package size and high reliability performance for automotive CMOS image sensor (CIS) application, wafer level chip scale packaging (WLCSP) technology using through silicon vias (TSV) needs to be developed to replace current chip on board (COB) packages.

WLCSP bumps have traditionally been produced by dropping preformed solder spheres through a metal template onto silicon wafers using modified surface mount stencil printers (1).

Solder bumping is often separated into several different categories: flip chip bumping (FC), wafer level chip scale packaging (WLCSP), and ball grid array (BGA). This categorization and affiliated nomenclature is partially based on the solder bump size …

WLCSP. Because of rapid movement toward semiconductor package miniaturization, a number of solutions have evolved as well that retain an outline that is the same or very near the same as the die element - WLCSP is one of the solutions which …

WLCSP+ utilizes the FlexLine process flow with advanced dielectric materials for improved reliability as well as low temperature process. WLCSP+ is capable of 10um via opening size with 10um cured dielectric material thickness on 12” wafers. It can also be thinned down to less than 150um by the backgrind process.

2024年1月12日 · 1）晶圆级芯片封装（ WLCSP ），可直接在晶圆顶部形成导线和锡球（Solder Balls），无需基板； 2） 重新分配层 （RDL），使用晶圆级工艺重新排列芯片上的焊盘位置1，焊盘与外部采取电气连接方式；

晶圆级芯片尺寸封装(WLCSP)技术已成为低成本、小型化电子设备常用的封装方案。本文概述了WLCSP技术，包括主要特点、制造工艺、可靠性考虑因素和最新发展[1]。 WLCSP简介. WLCSP技术始于2001年，当时安靠等公司从Flip Chip Technologies获得了UltraCSP技术的许可。
