Method for preventing assembly mixing during manufacturing

Disclosed is a method for preventing assembly mixing during manufacturing. Benefits include an improved manufacturing environment.

Background

� � � � � A limited number of tray colors are available conventionally. The additional cost of changing the color of a whole tray can be as much as 50%. The conventional marking method is not consistent and not flexible. The marking and/or identification block may not be very visible from a distance of more than about 10 to 15 inches.

        � � � � � Manufacturing and OEM assembly operations may not be able to identify a tray and the components or assemblies in them from more that about 15 inches away for inspecting sorted stacks for consistency prior to shipment or assembly use.

� � � � � Conventional technologies utilize an ID block with an alphanumeric code or a combination of the ID block and a hand-painted stripe (see Figure 1). The tray number is indistinguishable. The stripe is poorly and inconsistently applied.

General description

� � � � � The disclosed method enables the distinctive marking of injection-molded trays to aid in visual identification during factory operations for kitting, sorting, and preventing assembly/component mixing.

� � � � � This marking design and methodology enables easy conversion of existing molds and easy implementation for all new thick matrix tray molds for injected molded JEDEC style trays.

� � � � � The disclosed marking system enables easy recognition from 3 to 5 feet.

        � � � � � The key elements of the method include:

•        � � � � Moldable tool that incorporates the marking technology into the tray

•        � � � � Staggered identifier within the insert boundary

•        � � � � IPN and ID element design size

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved manufactur...
