摘要： An alignment apparatus and method that provides a pick and placement tool that picks matrix leaded modules from trays, places the modules into a self-aligning nest, picks the modules from the nest and places them on a printed circuit board. The specific location and orientation of the nest with respect to a printed circuit board is known by the pick and placement tool. Once the nest has aligned the module, the tool picks the module from the nest and places it in the appropriate location on the printed circuit board. The nest has sloped sides that angle toward that bottom and are slippery. These sides funnel the module toward the bottom of the nest and correct gross misalignment. At the bottom inside of the nest are locating features into which the leads of the module fit. Between the locating features are slip surfaces so that the module leads slide into the locating features, correcting fine misalignment. Embodiments of the nest work for matrix leaded modules, including ball grid array, column grid array, and land grid array modules.

摘要翻译： 一种对准装置和方法，其提供从托盘拾取矩阵引线模块的拾取和放置工具，将模块置于自对准嵌套中，从嵌套中拾取模块并将它们放置在印刷电路板上。 拾取和放置工具已知嵌套相对于印刷电路板的具体位置和方向。 一旦嵌套对准模块，工具将从模块中取出模块，并将其放置在印刷电路板上的适当位置。 巢有倾斜的侧面，朝着该底部倾斜，并且是滑的。 这些侧面将模块朝向嵌套底部进行漏斗，并纠正总体错位。 在巢的底部是定位的特征，模块的引线适合。 在定位特征之间是滑动表面，使得模块引导件滑入定位特征中，校正精细的不对准。 用于矩阵引线模块的嵌套工作的实施例，包括球栅阵列，列网格阵列和焊盘网格阵列模块。
