How to prevent static electricity in the process of SMT placement machine?
In the SMT production line, we will encounter the problem of static electricity, from the friction between the clothes and the dry air to the dry air, which is the end of the duckweed. If the condition is suitable, it is a few volts and the peak is hundreds of kilovolts, so anti static is the need to do in our work, today, the south. Give some measures to introduce mechanical anti electrostatic patch SMT.
Static electricity has three: static clothing, antistatic shoes (conductive shoes), electrostatic hand rings, antistatic shoes and electrostatic hand rings to guide the human body to avoid accumulation in the human body.
Ordinary clothes will have great electrostatic voltage in the walk (>1000V). And antistatic clothing does not happen when it moves. This is the main role of antistatic clothing, long strip antistatic clothing can not shield the inside of the clothing produced static (after wearing still >1000V), grid – like antistatic clothing can be shielded (<200V), the static electricity generated through the floor and the grounding line of various parts of the plant to the outside of the general grounding wire.
1, strengthen the consciousness of the workers on the anti static operation
2, reduce the poor production caused by static electricity
3, prevent static electricity from causing damage to the product
二，Scope of application: all SMT production lines
The generation of static electricity is not perceived, but the static electricity produces the voltage of tens of thousands of volts. When the static electricity comes into the tip (the static release point, such as the human finger), it releases all the energy in a moment, causing the contact material to be struck by electric shock, causing the capacitance, IC, line road and so on to be destroyed and burned, so that the product is strict. In the case of heavy damage, static electricity measures should be taken. .
四，The contents of the operation
（一）Prevention and treatment of human static electricity
1, the workers should wear electrostatic clothing, work shoes;
2, the operator should take electrostatic gloves when working.
3, the operator should take an electrostatic ring in the operation.
（二）Prevention and control of static electricity
Make use of electrostatic materials to produce production tools.
2, the storage place to prevent static electricity;
（三）Prevention and control of static electricity of a worktable / mobile vehicle
1, the anti static film should be pasted on the work table.
2, the operation platform / mobile vehicle must have antistatic grounding chain.Prevention of equipment static electricity: good grounding wire
（四）Prevention and control of material static electricity
When the material is taken, the operator should use the antistatic method: with electrostatic gloves and electrostatic rings.
2, the material storage should be anti static measures: material cabinet to paste electrostatic film, grounding chain.
3, there should be anti-static measures in temporary storage area: installing grounding chain.
（五）Prevention and control of static electricity related to production: anti static measures should be taken when using items related to production: static wires and antistatic films.
The online operators should strictly abide by this rule
The online operators are supervised by the team leader, and the engineers are supervised by the engineers.
SMT filter cotton is usually replaced in three months, otherwise it will be blocked, affecting the use effect.
Filter has the following characteristics.
1.Is a high performance and high efficiency filter cotton non-woven processing using organic hot-melt synthetic fiber and;
2, increasing structure, using gradually encrypted multi-layer technology, that is, the fiber density in the direction of pure air will increase gradually, and the higher filtration efficiency can be blocked at different levels of density according to the size of dust, which will more effectively accommodate more dust.
3, efficient filter cotton sticky treatment, filter material after full dipping, because the adhesive penetrated the media completely, so that the dust particles can not pass through, so that the overall filtered air flow evenly diffused, forming laminar flow state, to achieve the best spraying effect.
Does anyone need SMT filter cotton? Factory price.

Three general classes for the intended end use of electronic assemblies have been established. As applications and functionality increase there may be overlap of equipment between classes. The owner of the application has the responsibility to determine the class that applies. Although a single class may be referenced, specific requirements defined in other classes may apply as well. If a class is not stated for a criterion then the single criterion applies to all classes.
Class 1: Consumer Products: This class of product includes non-critical applications which shall be reliable and cost effective but for which extended life is not the primary objective. Examples include products manufactured for general consumer applications.
Class 2 – General Industrial. This class includes high performance commercial and industrial products in which extended life if required but for which uninterrupted service is not critical. Application and environmental considerations should be taken into account.
Class 3 – High Reliability. Equipment in this class includes those equipment which continued performance is critical, equipment whose downtime cannot be tolerated, or equipment used as a life support item. Unless otherwise specified, Class 3 shall be used for soldering requirements on military electronic equipment.
Printed circuit assemblies are manufactured in a variety of ways, exclusively using smt devices or smt mixed with through-hole components. Boards which have both SMC’s and through-hole components are called mixed technology boards. Surface
mount components are conventionally attached to the substrate using the reflow or the wave soldering process. Typically PCBs are assembled in one of the following ways and categorized as:
SMC’s only are placed on one or both sides of a printed circuit board. The components are attached via the Reflow soldering process.
A combination of both surface mount and insertion mounted components on a printed circuit board. Both SMC’s and IMC’s are assembled on the top side of the board while SMC’s only are attached to the bottom of the board. Top side smt components are Reflow soldered, while the through hole and bottom side smt components are Wave soldered.
IMC’s are assembled on the top side of the board while SMC’s only are attached to the bottom of the board. The components are soldered in place via the Wave solder process.
The fast growth of these applications and advanced packages has led to the development of high density boards. As the industry increases the use of these boards and packages in its products, two of the greatest challenges that it will face are; establishing effective printing guidelines and utilizing equipment that can reliably produce a wide variety of assemblies.
A company’s success or failure in the surface mount industry will weigh heavily on its ability to adapt to automated manufacturing practices through innovative product design and development. Manufacturers can effectively compete in the electronics marketplace today only by utilizing automated equipment throughout the entire SMC assembly process. This includes addressing changes in the SMC production process from initial board printing to final inspection. The companies that do not act positively on these factors and successfully adapt to changing trends in the electronics market will find their business being lost to competitors and foreign ventures.

The following procedures explain how to properly clean and test an ESD surface.
Clean an ESD Surface
Do not use abrasive or highly alkaline cleaners on polycarbonate. Never scrape polycarbonate with squeegees, razor blades, or other sharp instruments. Benzene, gasoline, acetone, or carbon tetra chloride should never be used on polycarbonate. Do not clean polycarbonate in the hot sun or at elevated temperatures.
Using a sponge or soft cloth, wash the ESD-protected surface with either a mild detergent or Windex product and lukewarm water.
After washing, rinse with water and dry thoroughly with a chamois or moist cellulose sponge to prevent water spots.
To protect the ESD surface after rinsing and drying, recommends applying Kleenmaster Brillianize®. This application helps to maintain the static dissipative coating and reduce the accumulation of dust.
Test Static Dissipative Covers
Periodically and after maintenance, check the machine covers to determine if the dissipative qualities of the cover have changed. The following procedure ensures that static dissipative covers are in fact dissipative.
Surface resistance meter (such as 3M 701 Surface Resistance meter and probe).
The surface resistance should be less than 109 ohms in all areas. If the cover package is no longer dissipative, contact you Universal Instruments Corporation sales representative.
Clean the static dissipative covers using the Clean ESD Surface procedure to ensure the accuracy of the test.
Using the surface resistance meter, follow the instructions provided by the manufacturer to measure the surface resistance of both the inside and outside of the covers. Measure the resistance at all four corners and at several areas in the middle of the cover. This test checks the integrity of the ESD coating.
Connect the ground path resistance probe to the meter and chassis ground.
The path to the ground should not be higher than the surface resistance. If it is, clean the frame connections, repair loose or corroded fasteners and ground straps, and check tracks for dirt and/or corrosion.
4. Measure the ground path from the covers to the chassis ground. Take this measurement from both surfaces and all four corners of each cover.
