Occasionally received such advice customers: Factory pre-qualified devices and the use of anti-static bag, but transportation to the customer open the package, but found that some PCB board or device does not work out, do not know what causes it? Exploration since reason, first understand the most commonly used anti-static material, there are two, one for anti-static PE bags, anti-static material base is made of low density polyethylene (LDPE) + linear low density polyethylene (LLDPE) + antistatic + color pigment mixed stabilizer blow molding, then cut off the seal forming, and its products (anti-static PE bags) has all the features of ordinary PE bags and anti-static function. Another anti-static shielding bags, anti-static bag buy unique structure can be formed induction hood effect protect the bag of goods and electrostatic field isolation, how much anti-static bag to prevent accumulation of static electricity from electrostatic damage. There are a variety of models can be used to describe how the device is compromised, such as the human body model (HBM), Machine Model (MM), Charged Device Model (CDM) and the impact of the electric field of the device and so on. For the purposes of automated assembly equipment, anti-static bag specifications, the main consideration after three damage model (model), we discussed separately below. Machine model / mode automatic assembly equipment rails, belts, slides, element transporter and other devices to move the device to make it according to process requirements of the direction of movement, Hebi anti-static bag, might on if the device is designed properly, belts and transport systems accumulated a large number of charges, these charges will be in the process of discharge through the device. Equipment components discharge through the device called the machine model / model. Red Plastic Factory (Figure) _ Anti-static bags Specification _ Hebi anti-static bag provided by Xiong red plastic factory. Red Xiongxian plastics plant (tztz89647.ynshangji.com) is a professional, "plastic film, food bags, garbage bags, craft bags, gift bags," the company.
