Universal Tray for Shields

Abstract

To eliminate the need for a dedicated tray for new shields  we invented the Universal Tray which can accommodate all range of components.

Introduction

This paper deals with universal tray for shields.

In Prototype phase we have to assemble on PCB many new shields in large range of sizes and configurations. Most of them are sent from vendor in bulk and not in the std. packing which is a dedicated  Tape & Reel or plastic tray with special cavities. In order to transport those parts at the factory and assemble them on the PCB, special metal trays are designed and produced for each and every new shield. Those trays are being stationed in the placement machine with the components inside.

We substitute the dedicated trays by the universal trays.

Problem To Be Solved

                  The current situation is that we Design and produce a dedicated metal tray for each and every new Shield. Such a dedicated tray cost $300 per tray. If we have 10-20 trays in an average project. The Total costs for trays can be ~$3000-$6000. 

In addition designing & producing the trays may take at least one week. This time lag and the costs involved increase the project cycle time and sometimes delay the production date. In an era of reduced time to market, any delay in prototype production may be critical.


Proposed Solution to the Problem:

Following is a drawing of a universal tray for shields:
