Description
Considerable interest exists in the process known as the pin-in-paste, or the Alternative Assembly and Reflow Technology (AART) process. The AART process allows for the simultaneous reflow of both odd-form and through hole devices as well as surface mount components. This process has several advantages over the typical mixed technology process sequence that includes wave soldering and/or hand soldering, often in addition to reflow soldering. The advantages include, but are not limited to, the following: multiple operations can be condensed into one comprehensive process; fewer pieces of equipment, materials, and personnel are necessary; a reduction in cost and cycle time can be realized; the high defect rate associated with wave soldering may be reduced; and it eliminates one or more thermal process steps thereby improving solderability, electronic component reliability, etc.
