Abstract
The invention relates to a method for attaching a semiconductor chip to an ink jet pen body and improved construction techniques therefor. According to the method a first adhesive have a cure time greater than about 15 minutes is dispensed in a predetermined pattern in one or more chip pockets of an ink jet pen body. Beads containing a second adhesive are dispensed in two or more discrete locations around an inside perimeter of each chip pocket. A semiconductor chip having chip edges is attached to the second adhesive in each of the chip pockets and the first adhesive is cured using heat or radiation. Use of a dual adhesive system improves the alignment of the semiconductor chips relative to one another until the first adhesive is completely cured.
