One of the common problems with Black Conductive Film blown film is that the blown film melt is broken.

Black Conductive Film

Phenomenon: due to the too high viscosity of the melt, a significant velocity gradient is formed during the extrusion die, resulting in forced drag, which forms a surface defect. After being frozen, it presents a wavy pattern, commonly known as shark skin . There is a special article on the analysis of shark skin problems.

Solution:

1.Increasing the temperature setting improves the fluidity of the melt;

2.Increasing the lip temperature reduces the viscosity of the melt in the die;

3.Widening the die gap to attenuate the velocity gradient;

4.The use of processing aid PPA acts as a lubricant;

5.Resin with good fluidity: high melting point, wide molecular weight distribution, long chain branched resin;

6.Properly reduce the amount of extrusion;

How to prepare Glass Epoxy Tape? After the glass adhesive tape is wound around the iron core, how to dry and solidify it?

Glass Epoxy Tape

(1) Prepare materials.

0.1×50mm alkali-free glass ribbon, 624 or 101 epoxy resin, triethanolamine, industrial pure alcohol or ethanol.

(2) Preparation method.

The alkali-free glass ribbon roll was loosened and placed in an oven for de-waxing treatment at 100-120 ° C for 2 h. The epoxy resin is melted into a flowing liquid at 50 to 60 °C. Add a small amount of alcohol to 100 parts of epoxy resin. After mixing, add 8~12 parts of triethanolamine, continue stirring and add alcohol to make the glue viscosity reach 25~30s (using viscosity meter No.4). The dewaxed glass ribbon is immersed in the glue for 2 to 3 seconds, and the glue is dripped and ready for use.

(3) The drying and curing of the glass adhesive tape is generally baked in a baking oven at a temperature of 120 to 130 ° C for 8 to 12 hours, and baked until the epoxy glass ribbon is discolored.

Anti-Static Shielding Bag is commonly used for the packaging of electronic components to prevent damage caused by electrostatic power generation that is prone to electronic components. Generally, the antistatic shielding bag adopts a two-layer composite or a higher four-layer structure. The Faraday cage induction cover effect is formed in the bag to protect the contents of the bag from the electrostatic field to the greatest extent, preventing static electricity from accumulating and protecting against static electricity.

Anti-Static Shielding Bag

The Shielding Bag has excellent functions such as anti-static, anti-radio frequency, waterproof vapor penetration, salt spray prevention and so on. Their unique four-layer structure creates an “induction cover” effect to protect the contents of the bag from the electrostatic field. The inner layer is made of static-eliminating ethylene and has excellent anti-static properties. The inner and outer layers of the material are made of transparent anti-static material, and the middle is a translucent conductive metal layer, so it has good anti-static and electrostatic shielding properties.

The Antistatic Protective Belt is made of high transparent PET, coated with acrylic glue or silica gel on one side, and coated with special antistatic layer on the other side, and then laminated to form a release film. The production and slitting in the dust-free space ensure the high quality of the product while ensuring its ultra-transparent characteristics. The unique anti-static treatment can effectively prevent the adsorption of dust and impurities, and the screen is always new.

Antistatic Protective Belt

Features:

1. The surface is antistatic and is not easily absorbed by dust and impurities;

2. Using advanced coating technology, it is not easy to leave fingerprints when touched directly;

3. Electrostatic adsorption, automatic exhaust, not easy to generate bubbles, not easy to fall off, leaving no trace after removal;

4. The picture is purer, the eyes are easier, and the eyesight is effectively protected.

Uses:

Widely used in LCD monitors, notebook computers, touch panels, flat computers, mobile phones, PDAs, MP3s, digital cameras and other products that need screen protection.

With the rapid development of the electronics industry, the integration of electronic circuit boards is getting higher and higher, the high density of electronic components on the motherboard, the compact wiring, and even the widespread use of surface-mount components are likely to cause electrostatic damage to the circuit board. . When a US organization tested an integrated circuit in a large communication system equipment, it was found that one-third of the faulty integrated circuits were broken down by electrostatic discharge. Antistatic Protective Belt products with antistatic film can prevent static damage to the integrated circuit.

There is no strict definition of functional films, and generally refers to films that have certain (or some) special functions that are not available in general-purpose films and can meet the special needs of applications, such as antistatic films, rust-proof films, and heat shrinkage. Film, easy to open film and so on. Since the functional film has such a special function or the like, it can better meet the needs of protecting the packaged goods, or better meet the requirements of the convenience of use of the product, and thus has a better use effect; the functional film Usually with high technical content, high economic efficiency and strong market competitiveness, it has attracted people’s attention.

PE Antistatic Protective Belts are important varieties in packaging materials, and are often indispensable materials in certain packaging fields. They are of great importance in plastic packaging materials.

Black PET Leader Tape, mainly used for the protection of various glass and plastic surfaces, that is, no residual glue, and the peeling voltage during the control period, so that the protective film is peeled off without generating a large voltage breakdown.

The period is mainly divided into one-sided (with rubber surface) anti-static, double-sided (with rubber surface, reverse surface) anti-static two.

Anti-static with rubber surface, the principle is to add anti-static agent in the glue and then apply glue to make it have antistatic effect.

Anti-static anti-static, there are two ways: one is to apply a layer of anti-static coating on the PET film, and the other is to add antistatic agent when PET is produced. The former method of coating is easy to damage the coating during storage and transportation, and the antistatic effect is weakened, which is why the antistatic protective film has a shorter shelf life than the ordinary protective film, and the advantage is low cost.

The latter method of adding antistatic agent has the disadvantage of high cost, but its relatively long shelf life makes many users choose to use this protective film in shipping protection.

TX Copper (Cu) bondingwireoffers significant cost advantage over Gold (Au) bonding wire. Our Cu bonding wire is an excellent replacement for Au bonding wire due to its similar electrical properties and the cost advantages.

Self inductance and self capacitance are nearly the same and Cu bonding wire has lower resistivity. 

In applications of QFP, QFN and SOIC where resistance due to bond wire can negatively impact circuit performance, using TX Cu bonding wire can offer better improvement. Also, a tailor-made concept of TX Tech is partnering with various interested parties for advanced packaging to continue to expand knowledge and lead technology development.
