WHY STATIC CONTROL IN ELECTRONICS IS SO IMPORTANT？

FOR SEMICONDUCTOR

From wafer fabrication to IC packaging and testing, Static eliminators are widely used across equipment and workstations

--Wafer Probing Testing

Wafer Probe Testing, also known as Chip Probing (CP) or Wafer Sort, is a critical electrical test performed on a semiconductor wafer before the individual chips (dies) are cut and packaged

Metal probes contact and separate from IC pads repeatedly,causing triboelectric charging, accumulating static charge on probes and chip

• Pulse AC Ion Bar of AP-AB1216 Provides broad-based, foundational static neutralization
• High-frequency AC Ion nozzle of AP-DC3203 provides localized, precise, and powerful static neutralization

--Clean Environment for Wafer Fabrication

The customer is a leading domestic FAB producing epitaxial substrate wafers, requiring static reduction to minimize particle adhesion

Process sections requiring static control: Cleanroom areas of ISO Class 10/100, mainly covering product storage, material transfer, and equipment port locations where wafers are prone to particle adhesion

Typically ceiling ionizers AP-DB1233 installed beneath the FFU by suspension or surface mounting, the ionizers neutralize static charges in the space to maintain balance and reduce particle adhesion

FOR LCD/OLED OPTOELECTRONIC DISPLAY

Both front/back-end screen factories and module OEMs use ionizers extensively throughout the production process.

--In Front-end Display Production

strict ESD and ESA control is required at all process stages to prevent static damage to etched circuits and particle contamination. Ionizers are widely used, mainly at equipment ports and CV lines in unit modules

--In The Back-end Module Stage

Sensitive displays undergo tasks like film peeling and lamination. With more manual operations than the front-end, ionizers are used at equipment and workstations to control static.

FOR 3C ELECTRONIC DEVICES

Static eliminators are used inside equipment and at operator assembly workstations to ensure proper ESD protection

--Electronic Product Assembly

Electronic product assembly uses ionizers to prevent static discharge that can damage components and cause product defects

--3C Electronic Devices

Static eliminators are installed inside 3C electronic devices to prevent electrostatic buildup that can interfere with circuits, affect performance, or cause component damage

FOR AUTO ELECTRONICS & PARTS

ESD protection is increasingly important for both electronic devices and parts to prevent static damage, ensure stability, and avoid failures or losses

--Automotive Electronics Production

As cars get smarter, more different types of ionizers are used in production to prevent static damage and ensure system stability and safety

--Automotive Parts

Automotive parts and interior/exterior trim undergo surface coating, and ionizers are used to remove static dust to ensure a flawless finish, Ionizing bars combined with air knives can be used to blow off dust from the surface of parts

Stubborn dirt may require dry ice cleaning, which removes contaminants by impacting the surface. This process can generate static, causing dust to reattach, so ionizers are used—either installed at the dry ice nozzle for simultaneous neutralization or applied afterward for secondary static removal

FOR LITHIUM BATTERY

From materials to pack assembly, Ionizers control static and dust to improve battery yield and performance.

--Lithium Battery Production

During production, lithium battery separators generate static from frequent contact and separation with rollers and during winding or unwinding. Ionizing bars are used frequently to remove static from the separator surface

Ionizing bars are used frequently to remove static from the separator surface

--Winding/Stacking

During the winding or stacking of positive and negative electrodes and separators, rapid friction and separation generate high static charges. This static can cause the layers to stick together, affecting assembly, and may also lead to active material detachment from the electrode surface

Different types of batteries use either winding or stacking processes. In both cases, there are many rollers and traction paths, so Ion bars are usually installed before and after the traction rollers, covering both the upper and lower sides of the separator. (Typically 10–14 sets are used.)

Module Assembly:

During cell-to-module assembly, contact and friction between cells and parts generate static, which can damage insulation and cause short circuits. Installing ion bars to neutralize static on cells and parts

Pack Assembly:

When assembling modules into battery packs, static may also occur, potentially affecting or damaging electronic components like the BMS, Ion bars always the best solution.

FOR SMT

In SMT production, static removal and protection are needed at every stage, from printing to soldering and inspection

In electronic OEM factories, especially in SMT processes, static removal and ESD protection are required at

every stage—from PCB printing to component placement, soldering, and AOI inspection. Details are as follows:

• Before PCB printing: Static removal is needed to eliminate dust or particles generated during PCB cutting.
• During Component Placement: Static charges can occur when feeders peel components due to material properties of reels or parts, which may cause ESD events.
• After soldering: Due to the high temperature of the reflow or wave soldering furnace, ionizing bars or fans help cool down and remove static charges.
• During AOI inspection: Since this step often involves manual handling, ionizing fans are used to blow the working area to prevent ESD when operators touch the products.

FOR ELECTRONICS ASSEMBLY

For electronics and home appliance manufacturers, ionizing fans or bars are often used at manual workstations to control static during assembly

In certain electronic assembly processes, manual operation areas often require static eliminators to be installed at the workstations for effective static elimination and protection

FOR STATIC SENSOR

The electrostatic voltage sensor monitors surface voltage in real time, visualizes static levels, supports alarms and data logging, and helps trace ESD events to ensure safe electronic manufacturing.

In the electronics industry, almost every sector requires static eliminators because electrostatic discharge (ESD) can easily damage sensitive electronic components. Even a small static charge can cause product defects, reduce yield rates, or shorten the lifespan of devices.

During production processes such as PCB assembly, SMT, semiconductor fabrication, display panel manufacturing, and electronic device assembly, static charges are generated by friction, separation, or contact between materials. These charges can lead to problems such as dust attraction, component misalignment, or direct ESD damage to chips and circuits.

Static eliminators — including ionizing bars, blowers, guns, and nozzles — are therefore used to neutralize static charges and maintain electrostatic balance. By effectively controlling static, manufacturers can improve product quality, ensure production safety, and reduce losses caused by electrostatic failures.
