摘要： A ball grid array semiconductor device (30) includes a plurality of conductive balls (36) and a plurality of conductive castellations (18) around its periphery as redundant electrical connections to a semiconductor die (12). During testing of the device in a test socket (50), the conductive castellations are contacted by test contacts (54). The test contacts do not come in physical contact with the conductive balls. As a result, when testing is performed at elevated temperatures near the melting point of the conductive balls, the conductive balls are not deformed by the test contacts, thereby eliminating cosmetic-defects. Additionally, the absence of physical contact between the conductive balls and the test contacts during testing reduces the likelihood that conductive balls will inadvertently fuse to the test socket or create solder build-up on the test contacts.

摘要： A pad array semiconductor device (35) includes a thermal conductor (28) integrated into a circuitized substrate (14). A semiconductor die (12) is mounted on the substrate overlying the thermal conductor to establish a thermal path away from the die. The thermal conductor may also be covered or surrounded by a metallized area (37, 39), which together may serve as a ground plane in the device. Preferably one or more terminals (26) are attached to the thermal conductor for improved thermal and electrical performance. One method of integrating the thermal conductor in the substrate is to position a metal plug into an opening 30 of the substrate. The plug is then compressed or otherwise plastically deformed to fill the opening and create a substantially planar substrate surface.

摘要： Plastic encapsulated semiconductor devices are susceptible to moisture due to the permeability of molding compounds. Devices may be baked until dry before being shipped to the customer to reduce the risk of cracking. To retain this dry condition, devices are packaged and shipped in dry-packs. A vacuum seal indicator (18) for flexible material enables a user to determine the integrity of a vacuum seal. The seal indicator has a quick recognition pattern composed of either negative (22) or positive (24) features or a combination thereof, and is placed inside a dry-pack bag (30) which is vacuum sealed prior to shipping. The integrity of the vacuum seal can be determined by looking at the dry-pack bag to see whether the recognition pattern is sharply defined against the bag or not. The vacuum seal indicator can be used in conjunction with any shipping media (28) as long as the outer bag is flexible.

摘要： Routing density of a wiring substrate (10) is increased by providing a nested plating bus (18) as a supplement to an external plating bus (16). A first group of conductive traces (14) is connected to the nested plating bus, while another group of traces is connected to the external plating bus. After the conductive elements are plated, the nested plating bus is removed by etching, milling, or stamping techniques. Use of a nested plating bus increases I/O count for a given substrate area and/or reduces the need to have routing on more than one layer of the substrate.

摘要： A method for packaging an integrated circuit begins by providing an organic substrate (310) having at least one device site (312). Within each device site, one or more electronic devices (532) is mounted. Around the device site, slots (316) and corner holes (318) are formed. In one embodiment, a negative feature, such as a notch (326), is formed in the substrate along the inner edge (315) of the slots. After the electronic device is mounted and encapsulated in a plastic package body (320), the device is excised from the substrate by punching corner regions of a final package perimeter (317). The placement of the slots, corner holes, and notches results in a punch periphery that is free from burrs, provides maximum active interconnect area, and minimizes surface and/or edge damage during the punch operation. Instead of forming notches, a positive feature, such as a protrusion (426) can be incorporated into a punching tool segment (428) to provide the same benefits.
摘要翻译：一种用于封装集成电路的方法通过提供具有至少一个器件位置（312）的有机衬底（310）开始。在每个设备站点内安装一个或多个电子设备（532）。围绕设备现场，形成槽（316）和角孔（318）。在一个实施例中，沿着槽的内边缘（315）在衬底中形成负特征，例如凹口（326）。在将电子设备安装并封装在塑料封装主体（320）中之后，通过冲压最终封装周边（317）的拐角区域将装置从基板上排出。槽，角孔和缺口的放置导致没有毛刺的冲头周边，提供最大的有源互连面积，并且在冲压操作期间最小化表面和/或边缘损伤。代替形成凹口，可以将诸如突起（426）的积极特征结合到冲压工具段（428）中以提供相同的益处。

摘要： A wire bondable plastic encapsulated semiconductor device (58) having no die supporting surface can be manufactured. In one embodiment, a semiconductor die (22) and a plurality of conductors (12) extending toward the periphery of the die are provided. The die is rigidly held in place on a workholder (60) with a vacuum (62) for the wire bonding process. Wire bonds (26) electrically connect the die to the conductors. The wire bonded die is then placed inside a mold cavity (64), and a resin encapsulated is transferred into the cavity under elevated temperature and pressure to form package body (70) around the die, the wire bonds and a portion of the conductors. Before the package body is formed, the die is supported solely by the the rigidity of the wire bonds since there is no die supporting surface connected to the conductors.
