Q:<\/strong> In our organization, there is a lot of paperwork that accompanies the product. Is this harmful to the product due to static generation? I have measured all the documents surface resistivity and find it to be dissipative in nature. Our production environment humidity is controlled from 40%-60%. I also tried to tribocharge the paper but there is no static voltage generated. The funny thing is when I rub my plastic comb and put it near bits of small paper, the bits get attracted to the comb. So is paper really harmful to the semiconductor products that we manufacture for our customer?<\/p>\n

\"ESD<\/a>

ESD Dissipative \/ Cleanroom Paper<\/p><\/div>\n

A:<\/strong> Hello.\u00a0 It\u2019s good for you to observe the possible generators of static in an EPA (Electrostatic Discharge Protected Area) and to remove all non-essential insulators and to ground conductors or soft ground them, as the case may be, and to use neutralization on isolated conductors and essential insulators (ionization).\u00a0 You may notice low static charge potential or voltage on that paper, but what happens when it tribocharges with other materials in the EPA?<\/p>\n

If you feel the paper is in the Static Dissipative range and you\u2019ve got it sitting on an ESD bench mat, there should be no worries.\u00a0 If the paper has a surface resistivity of 1.0E9 \u2126 at your nominal humidity or less, all the better.\u00a0 If it\u2019s above 1.0E11 \u2126 , it may or may not dissipate a big enough charge quickly enough\u2026 It\u2019s sort of a risk.\u00a0 If you\u2019d be interested in a more conductive ESD paper, we offer the SDP-8.5×11-W<\/a>.\u00a0 This product is not humidity dependent.\u00a0 Having humidity is great at 30-50% range is helpful to get the best result.\u00a0 The Static Dissipative paper will still be below 1.0E10 \u2126 with humidity as low as 20%.<\/p>\n

\"Sheet<\/a>

Sheet Protectors<\/p><\/div>\n

The next product that is helpful is the Document Protector which can be used on drawings, instructions, ECNs ECOs etc. that would be needed in the Production Area; we provide the DP-8.5×11<\/a> which is also Static Dissipative.\u00a0 The product is designed to be less than 1.0E11 \u2126 which is considered Static Dissipative for packaging and similar materials and it\u2019s also said to be low charging or resistive of tribocharge.\u00a0 The static decay meets the specs for environments involving sensitive electronics and would be considered low-charging as well.<\/p>\n

So you have decisions to make.\u00a0 You may be safe with what you\u2019ve got, but if you\u2019d like to be safer and more robust to lower humidity, you may consider the products above.\u00a0 If you\u2019re ever in doubt, keep the documents at least 12\u201d from sensitive electronics.<\/p>\n

I hope this was helpful information to you.\u00a0 Please contact Alan<\/a> for pricing and availability.\u00a0 Thank you for contacting us.<\/p>\n","protected":false},"excerpt":{"rendered":"
