Universal Tray For Ball Grid Array (BGA)

By Gazit Shmuel, Weinbren Shai and Uzi Cohen

Abstract

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

Introduction

In Prototype phase we have to assemble on PCB new BGAs in large range of sizes and configurations.� Some of them are sent from vendor in bulk and not in the standard packing, which is a dedicated tape and reel or plastic tray with special cavities.� Others are sent in a tape and reel but are taken off the tape during proto preparations.� 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 BGA that has no standard packing.� 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 many of the new BGAs.� Such a dedicated tray cost 4300 per tray.� If we have 10-20 trays in an average project the total costs for the trays can be $3000 - $6000.

In addition designing and 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.
