ITEM #: 11508872
Ion bar must be used with HV Controller - Item50855Recommended Process ion bar technology Cost-effective alternative to overhead ionization Reduces particulate contamination Effective ESD control within a Laminar Flow Hood or Mini environment Lightweight, small, cross-sectional design allow it to fit in tight spaces Ion bars can be daisy-chained to connect multiple bars in sequence. One power supply can drive up to 40 emitter tips. Jumper can be made in lengths to fit every need Constructed of ABS plastic and aluminum top caps for ease of mounting Bars are pre-drilled with mounting brackets Rapid neutralization over a localized area Replaceable bayonet style thoriated tungsten emitters Controllable pulse rate DC ionization Current limited emitters Controllable polarity balance Choose from four styles of controllers:1. Recessed potentiometer adjustment, 120V;2. Recessed potentiometer adjustment, 220V;3. External potentiometer adjustment, 120V;4. External potentiometer adjustment, 220V; Bars can be customized to fit any length Made in the United States of America Necessary non-conductors in the environment cannot lose their electrostatic charge by attachment to ground. Ionization systems provide neutralization of charges on these necessary non-conductive items (circuit board materials and some device packages are examples of necessary non-conductors). Assessment of the ESD hazard created by electrostatic charges on the necessary nonconductors in the work place is required to ensure that appropriate actions are implemented, commensurate with risk to ESDS [ESD sensitive] items. (ANSI/ -2007 Foreword) In order to mitigate field-induced CDM [Charged Device Model] damage, the ESD program shall include a plan for the handling of process-required insulators. If the field exceeds 2, 000 volts/inch, steps shall be taken to either: A) Separate the insulator from the ESD-sensitive device by a distance of 30 cm (12 inches); or B) Use ionization or other charge mitigating techniques to neutralize the charge. (ANSI/ -2007 section 8.3) The primary method of static charge control is direct connection to ground for conductors, static dissipative materials, and personnel. A complete static control program must also deal with isolated conductors that cannot be grounded, insulating materials (e.g., most common plastics), and moving personnel who cannot use wrist or heel straps or ESD control flooring and footwear. Air ionization is not a replacement for grounding methods. It is one component of a complete static control program. Ionizers are used when it is not possible to properly ground everything and as backup to other static control methods. In clean rooms, air ionization may be one of the few methods of static control available. (ESD Handbook Ionization, section 5.3.6.1) All ionization devices will require periodic maintenance for proper operation. Maintenance intervals for ionizers vary widely depending on the type of ionization equipment and use environment. Critical clean room uses will generally require more frequent attention. It is important to set-up a routine schedule for ionizer service. Routine service is typically required to meet quality audit requirements. (ESD Handbook TR 20.20 section 5.3.6.7 Maintenance / Cleaning) "Activities that handle items that are susceptible to less than 100 volts HBM may require additional control elements or adjusted limits.
