Method for handling miniaturized components

Disclosed is a method for handling miniaturized components. Benefits include improved functionality, improved performance, and improved cost effectiveness.

Background

      Miniaturized components, such as resistors, capacitors, and inductors, can be displaced when loaded in standard waffle packs during assembly pickup and placement. Components can shift out of position or out of the pocket. These displacements/dislodgements can occur from any slight jarring of the waffle pack that occurs during handling. Examples include loading the waffle pack, transporting the loaded waffle pack from the load station to the pick-and-place tool, or loading the loaded waffle pack onto the tool’s feeder mount.

      Conventionally, no economical, commercially available solution exists. Of the assortment of component handling media currently available on the market, the use of chip trays provides the most cost-effective option. However, off-the-shelf waffle packs are not always dimensioned correctly to properly fit the components of choice. Oversized waffle pack pockets make part orientation difficult due to an increased opportunity for skewing and/or misorientation. Alternatively, obtaining the correct waffle-pack dimensions requires custom-sized packs, which are cost prohibitive.

      Gel packs are not conducive to accurate alignment during manual loading. Additionally, the manual loading of miniaturized components is an extremely nonergonomic condition due the requirement of controlled finger pressure over an extended length of time to avoid damaging the parts. The difficulty is emphasized by the fact that a single 2-inch x 2-inch waffle pack can a...
