Traceability Case Study AOI Component Traceability Project PC Manufacturer <-> Orbotech Electronics Assembly PC Manufacturer named CMf in this presentation September 2006

Orbotech AOI Executive Summary In July 2006 Orbotech successfully supported a collaborative pilot project for improved CMf customer experience The project focus for Orbotech was on AOI innovation for visibility and traceability at part level to improve quality metrics With the proven Orbotech solution, CMf can ensure better tracking of parts and products Implementing Orbotech AOI traceability at CMf EMS partners will help to reduce excursion breadth leading to cost savings and improved customer experience

Pilot Scope, Objectives, and Benefits Benefits 1:1 traceability for reduced excursion breadth Flexibility for different high value products Cost savings by limiting the number of resources and time when tracking defective products Improved customer experience

Pilot Goals Server Motherboard To read the 2D barcode on an individual chipset the alpha numeric marking on an LOM chip (LAN On Motherboard) Motherboard PPID during the SMT process Graphics Card Read the alpha numeric marking on the memory chips, the GPU, and the motherboard PPID (Parent Process Identification Number) For both products create a data association between the components and graphics card assembly.

Why AOI? AOI systems are an excellent match for the process for the following reasons: They can read and translate 2D barcodes (Intel chipsets) AOI has Optical Character Recognition (LAN on Motherboard (LOM) devices, graphics memory, and GPUs) Orbotech AOI systems were already in place at Foxconn on both Server and Graphics Card PCBA lines AOI equipment is programmable which makes it a flexible and scalable solution

Instant Process Control

Instant Process Control AOI Without Measurement And Immediate Action Is Like A Team With A Goalie And No Attack No more historical SPC what if s! A problem will be identified Direct the operator to the exact cause Then after adjustment Confirm and monitor production.

CIMCIS Computer Integrated Manufacturing Control & Information System This Error Measurement, Inspection and Feedback system collects data from boards in process and lets operators take corrective action when any segment of their line performance drops below a pre-set limit.

Manufacturers Needs. Maximum Return on Capital Expenditure Maximized Throughput. Minimal Scrap Minimal Non Value Added (e.g. Test.) Minimal Rework. Minimal Loss of Opportunity.

How can this be Facilitated? There are 2 obvious options to increase the Units per Direct Labour productivity metric. - Reduce the Operators. > - Increase the output. >

Equipment Utilization. Process States Model * Non Scheduled Time Equipment Downtime Equipment Uptime Manufacturing Time Unscheduled Downtime Scheduled Downtime Engineering Time Standby Time Productive Time Total Time Operations Time *Copyright, 1996 SEMI E10 96.

What is our Goal? Maximize Productive Time! Equipment Downtime Equipment Uptime Non Scheduled Time Unscheduled Downtime Scheduled Downtime Engineering Time Standby Time Total Time Manufacturing Time Maximize Productive Time Operations Time Copyright, 1996 SEMI E10 96.

What's the Problem? - Standard root cause analysis using time & motion of historical data shows only - 20% attributable to Major Stoppages 80% Loss of opportunity due to many intangible issues. 100% 80% 60% 40% 20% 0% 20 80

Where are we loosing time? 1st Pick & Place 100 Placements per cycle Best Cycle 60 Secs In a perfect world we produce 60 units per hour

Where are we loosing time? Material Replenishment Required Part Used 10 off per cycle Machine Stops & Alarms Part Replaced with a different Feeder Machine Starts Feeder Faulty & Begins to cause errors

Where are we loosing time? Machine has auto recovery mode Auto Recovery set at 1 Machine will stop when more than 1 CONSECUTIVE error occurs But Error is intermittent! Only causes error every other pick Machine DOES NOT STOP. Each recovered error adds 1/100th to the cycle time

Where are we loosing time? Cycle time increased by 10% We now only produce 54 units per hour in our perfect world. 10% down and only 1 hour into the shift. Each Unit produced adds $100 value to the Company In 1 hours we have lost a minimum of 6 units or $600

Where are we loosing time? 50% of the errors caused a part to be rejected/scrapped The part is worth $ 0.50 We have rejected 540 parts One faulty feeder has just cost you another $ 270 per hour

Where are we loosing time? Performance analysis run every 8 hours Assuming no other errors we will have lost 4320 parts at a cost of $2160 We have also lost 48 units with a value of $4800 One faulty feeder has just cost you another $6,960 The reel only has 5000 parts on it Oh - it was the last reel. Your stopped for material 5 hours into the shift & lost 3 hours

What is CIMCIS? Sächsischer Arbeitskreis Elektronik Technologie? Fully Scaleable Off the Shelf Manufacturing Management System. Modular Design allows functionality to be added as and when required.
