Permanent Antistatic Agents (Low Resistance) "PELECTRON"

The camera module market, including CMOS image sensors, is expected to continue to grow significantly, not only for smartphones, but also as key devices in automated driving technology. These precision electronic components, such as camera modules, are transported by conveyor trays, and then suckedgrabbed by robotic hands during assembly, which generates a peeling charge between the conveyor trays and the components. 

If a precision electronic component such as a semiconductor device is subjected to static electricity equivalent to its breakdown voltage, the device may be damaged or destroyed. 

 Camera modules are becoming more precise and high value-added,high added value, and depending on the device type, the band voltage of the transport material must be kept below 50 V to prevent damage or destruction by static electricity. 

1）Static Electricity Control Issues with Ionizers 

The application of ionizers as a countermeasure against static electricity can be considered, but the following issues must be addressed. 

• Ionization using an ionizer is performed by applying ions from the outside, which tends to cause unevenness in the static elimination area. 
• Due to the nature of ionizers, which apply ions from the outside, they are not good at instantly eliminating the exfoliating charge build-up between the device and the tray.
   
• When fan-type ionizers are used, the impact of dust emissions from the fan shaft cannot be ignored, especially in production lines where cleanliness is required. 

⇒Please consider using trays containing Sanyo Chemical's permanent antistatic agent "PELECTRON", which prevents dust attraction and electrostatic build-up.

2）Issues when Using Antistatic Agents

Ideally, the tray should provide static elimination and antistatic functions for materials used to transport precision electronic components, without relying too much on the ionizer alone. However, depending on the type of antistatic agent used in the tray resin and its usage, the tray itself may become a source of dust or have limited antistatic effect. 

Problems in antistatic agent selection 

• Imparting antistatic properties by adding conductive carbon-based materials: Dust emission due to carbon particles separating from the tray cannot be ignored, and unevenness in the static elimination area is likely to occur. 
• Imparting antistatic properties by adding a low-molecular antistatic agent: Low-molecular antistatic agents easily bleed out from resin surfaces, causing contamination and making it difficult to maintain antistatic effects. 

⇒A polymer-type permanent antistatic agent can be added to resin trays to prevent static electricity without causing the above problems and solve static electricity problems in precision electronic components. 

 "PELECTRON" gives the tray itself conductivity, so while it has a high static elimination rate, it does not reverse charge and does not deteriorate the ion balance. 
 It also eliminates the need for equipment setup and maintenance. We also offer a full range of technical services. ​

Comparison of permanent antistatic agent "PELESTAT"/"PELECTRON" products and carbon-based conductive materials

Compared to carbon-based conductive materials, "PELECTRON" is superior in that it can provide a uniform antistatic effect on the surface of resin trays, is less likely to be a source of dust, and does not impair the impact resistance or color selectivity of resin trays.

Sanyo Chemical's permanent antistatic agent (low-resistance) "PELECTRON" products includes grades for polyolefin resin (PP, PE) and ABS resin. 

We have a proven track record of adoption as a carrier material (trays, carrier tapes, packaging materials) for various electronic components and other products.
