用于安装半导体芯片的焊料滴涂
摘要：
本发明提供一种用于在衬底上安装半导体芯片的方法，该方法包含有以下步骤：在衬底上方设置焊料滴涂器，并将一段焊接导线穿越通过该焊料滴涂器到达衬底；在进给方向上使用导线进给器控制导线到达衬底的进给；使用定位设备沿着基本垂直于导线进给方向的至少两个正交轴线之一相对于衬底移动焊料滴涂器，同时进给焊接导线到达衬底表面，以便于在衬底上滴涂成行的熔融焊料；其后将半导体芯片安装在已滴涂在衬底上的熔融焊料上。
摘要（英）：

A method for mounting a semiconductor chip onto a substrate comprises the steps of positioning a solder dispenser over the substrate and passing a length of solder wire through the solder dispenser to the substrate. The feeding of the wire to the substrate in a feeding direction is controlled with a wire feeder. The solder dispenser is moved relative to the substrate with a positioning device along at least one of two orthogonal axes that are substantially perpendicular to the feeding direction contemporaneously with feeding the solder wire to the surface of the substrate to dispense a line of molten solder onto the substrate. The semiconductor chip is then mounted onto the molten solder that has been dispensed onto the substrate.
