ESD Control, Return On Investment. ESD CONTROL & (HUGE) COST SAVINGSRyne C. Allen. Desco Industries Inc. DII), Employee. Owned. November 1. 99. 9Reproduced with Permission, EE- Evaluation Engineering. INTRODUCTIONI. Introduction to ESD. Control Programs ESD Control programs are an essential part of a quality process and are always needed.
ESD sensitive electronic/semiconductor devices. The extent of the ESD.
Control program is determined by the ESD Sensitive (ESDS) devices themselves and how they. Refer to article "How to Set Up an ESD Control Program" [1] for. One of the main reasons that companies deploy ESD Control programs is to save money. Increased throughput and decreased scrap can yield a Return On Investment (ROI ) of up to. A secondary reason is to comply with their customers’ and ISO 9. Whatever reason, setting up and implementing an ESD.
Control program will almost always produce favorable financial results. II. Cost Reduction via ESD Control Programs. Having ESD awareness and following through with an ESD Control program is essential in. ESD. ESD can affect product reliability with catastrophic. Latent degradation is particularly. Maintaining good ESD controls will improve product throughput or yield, increasing. One test equipment manufacturer noted that GMR heads were being.
These heads are extremely sensitive to ESD, and require. It is very important when designing and implementing an ESD Control program to know the. ESD susceptibility of the ESD Sensitive (ESDS) devices you are trying to protect. Classification of these devices should include all simulation models human body model.
HBM), Machine Mode (MM), and Charged- device Model (CDM) that will properly characterize. This. will allow for the most economical program design. Gene Chase, an ESD Consultant with ETS Inc., is quoted as saying "Millions of. ESD [4]. Many of these incidents occur within the. Examples of losses from ESD may be any of the. Lost Time. Loss of Connection.
Loss of Data. Shocks to Personnel. Upset to A System Requiring A Re- Boot. Damage to Equipment.
Equipment Hardware Failure. To properly determine the return on investment (ROI) from your ESD Control program, you. Terry O’Malley, former AT& T ESD Manager, had collected data from several. AT& T facilities both before and after instituting an ESD Control program.
The data. speaks for itself; see figure 1 for a graph of two facilities that were monitored. There. was over a 5. ESD Control programs. Figure 1 – Cost Reduction From ESD Program, AT& T Office.

A typical return on investment. ROI) for a strict ESD Control program, like that used at Lucent Technologies, is. The design of the ESD Control program should be well thought out to. Protecting an ESDS device at all but one of the workstations is not acceptable.
For the. ESD Control program to be effective, it must be comprehensive and followed with discipline. Management commitment is an. ESD Control Program. ESD damage is not simple or.
To improve quality and profits, management should be involved. Over 2. 1% of failure analysis is due to electronics and industry studies showing that 3. ESD. Major companies including AT& T, Motorola, Hewlett Packard and IBM have been able to.
ESD damage cost and the resulting benefits of their ESD Control. Programs. These companies have determined that ESD Control is an essential part of their. Figure 1. Even with an ESD Control program in place, a typical electronics company may lose 5% of. Cost avoidance is the biggest issue when it. ESD Control program.
Another source [5] states that a typical. ESD control program is 9. For every one- dollar invested in ESD control. V. Increased Sensitivity to ESD Control and some causes. Difference in component sensitivity between through- hole and surface mount devices is. Typically, surface mount devices.

This implies that the spacing between the I/Os have decreased. I/Os even more susceptible to ESD. This can be seen as Ball Grid Array. BGA) chips have been replacing through- hole pin chip technology. The increasing sophistication of electronic devices has continued to make electronic.
ESD related damage. This is a trend that is expected. Dry areas further add to the susceptibility of ESD Sensitive (ESDS) devices. Table II. shows normal activity within a production facility where turboelectric charging levels of.

There are a slew of other factors that can add to the problems that need to be. ESD Control program, such as: employee knowledge with.
