ESD Systems - Questions And Answers

We have been working on ESD reduction to below 5 volts level in HGA (recording head assembly) manufacturing. We are responsible for dynamic electrical tester about 800 systems and looking for a proper solution to neutralize at tester working area 1 feet x 2 feet which involving with cables, keyboard, connectors and air hose. We hate to cover on replace the piece parts on those tester with dissipative materials, which are not practical. We are looking for something that we can install and get rid of the problem while has no effect to noise level of the test system (the tester system is very sensitive to noise and vibration). Your suggestion is very appreciated. - Sommai Kaewchouy, Seagate Technology (Thailand) ltd., Samutprakarn, Thailand

There are a few considerations for solution to your problem. Our bench top ionizer uses a controlled air flow to deliver the neutralizing charges, (balance is as low as +/- 5 volts) an ion bar assembly (needs to be mounted near proximity <2”), a topical antistatic, and dissipative spray. The most appropriate solution will depend on the machines requirements.
