Abstract

Latent threats to supply chain can often disrupt delivery, quality and work flow. This is even more of a disruption when latent threats manifest themselves thru second third tier suppliers. Supply chain disruption can become pervasive. An absence of addiitional second and third tier supplier controls pose a significant and pervasive threat tothe integrity of the global supply chain. The existence of defective material at any level of product assembly; from silicon wafers, through packaging substrates, to finished components can contaminate the manufacturing pipeline at all later stages of assembly. Complex global distribution systems can quickly spread such defects across national and corporate boundaries. This solution intends to address detection methods for intrinsic and latent issues that can become pervasive if not detected early enough in the supply chain. It takes inputs from selected aspects of the supply chain and focus's on analytics and using control points to minimize populating latent issues into the supply chain.

A Method to Control Second and Third Tier Supplier Management System in the Production Environment

An absent of the second and third tier supplier control process poses a significant and pervasive threat to the integrity of the global supply chain. The existence of defective material at any level of product assembly; from silicon wafers, through packaging substrates, to finished components can contaminate the manufacturing pipeline at all later stages of assembly. Complex global distribution systems can quickly spread such defects across national and corporate boundaries. A single batch of defective components can affect products for many companies, including those producing subassemblies and final assemblies - companies who may have neither visibility into, expertise in, nor the ability to manage, component-related issues. These issues can manifest themselves in late deliveries to the end client, problems during installation, or worse; end up as latent failures during the product's intended useful life

Why is it important to solve it? Threats to Supply Chain

Two of the largest threats to supply chain are reliability and latency. Both of these require comprehensive mitigation plans


1. Reliability concerns can be divided into two groups - induced and intrinsic

Induced occur when there are operations which detract from the reliability of the product

Examples of induced include

Uncontrolled excess reworks

      
Improper rework performed
Uncontrolled processes outside of spec windows
Counterfeit parts not contained at sub-tiers
These defects could show up during
manufacturing test, could result in performance issues
may be undetectable during these tests
occur at system power on at customer or sometime later as the system is operating in the field
Intrinsic would occur when there is a lack of quality management allowing a higher than expected fail rate on the part shipped to customer


2. Latency concerns occur when parts shipped to customer have quality issues with the parts that are not discovered until the sub-tier part now sitting in an OEM or tier one is subject to manufacturing testing

These are typically those 'marginal parts' that are not detected during the suppliers Functional Circuit Test (FCT)/In Circuit Test (ICT).Parts

with latency errors are usually classified as escape


The core aspect of this disclosure is a method using Cloud and Analyticswhich link 2ndand 3rdTier Supplier data and integrates this into the logistic and quality management structure of the producer to optimize the management of the supply chain

What can be done?

-

 - One solution is to develop an Emulation system to connect 2ndand 3rdTier data streams to the Producers logistics system in real time using Clouds. The integration of warehouse logistics, supply chain order system and manufacturing material planning system with the analytic engine
