Know About Antistatic FR4 Antistatic Fiberglass Sheet

October 09, 2024

Anti-static FR4 fiberglass board is made of non-alkaline epoxy resin filled with a certain proportion of carbon black after high temperature lamination of a semiconductor profile, specific gravity of 2.2g/cm3, working temperature 10 ℃ to 100 ℃ between the high mechanical strength and toughness and static discharge performance is stable, at room temperature conditions show a better elimination of static electricity, is more suitable for semiconductors and the use of dust-free environment.

Characteristics: stable antistatic performance, surface resistance value between 10^6-10^9Ω, volume resistance value between 10^5-10^8Ω, with good static discharge; the profile is a full antistatic plate, after mechanical processing, its antistatic performance will not change, even if the surface has been abraded, the electrical resistivity is unaffected; the surface is smooth and flat, diagonal warping is less than 3%; machining Good mechanical processing performance, drilling, flying edge and other processing will not produce plug holes and burr phenomenon; good dimensional stability, high creep strength, good rigidity; good flame retardant coefficient (UL94-V2 or more); good heat and moisture resistance, dry state, wet state electrical performance; low water absorption, not easy to deform.

Applications: semiconductor precision test boards, IC/wafer process jigs and fixtures, PCB test stands, LCD detector components, communication equipment components, electronic/optical test fixtures, precision instrument components, electronic components, fasteners and connectors.

Antistatic fiberglass panel is divided into surface antistatic fiberglass panel and overall antistatic fiberglass panel, this page introduces the overall antistatic fiberglass panel.

Overall antistatic fiberglass board, the whole provides uniform and stable antistatic performance, the surface resistance value and volume resistance value is the same, are 106 ~ 109 antistatic value does not change due to processing, cutting.

HONY Plastic antistatic fiberglass board features:

1、 Strong stability and long durability.

2、 Flame retardant grade UL 94-v0.

3, Temperature resistance grade B, short-term instantaneous high temperature of about 200 degrees, can not be used for a long time, otherwise there will be bending and deformation cracking and so on.

4, The appearance of the film to prevent scratching. The appearance of the product is very important, some products have more scratches on the surface, and there are pits and bumps, which will seriously affect the customer's production out of the fixture or the beauty of other products. Our anti-static fiberglass board in the handling, packaging, processing are standardized operations, the product surface is flat without bumps and scratches, beautiful and practical at the same time.

5、Color is black (if you need to spray other colors on the surface, please choose your own color and spray it by yourself).

6、Good flatness and low warping. Anti-static fiberglass board is a hot-pressed plate, so if it is not properly controlled, it is easy to make the product warp too much and affect the use of the product. Our company standardize the operation in the production process, long-term training and assessment of operators to reduce the warping degree, so that the product quality is good to satisfy customers.

7、No bad additions inside. This layman can not understand, what is meant by no bad additions? Simply put is to add some of the cost of raw materials than the proper low materials, added to the production of the plate. The main purpose is to reduce costs. So will it affect the performance of anti-static fiberglass board? Of course it will! Excessive filler material will greatly reduce the performance of the product, so that the quality of the product will be degraded.

So what are the uses of anti-static fiberglass board? Below is a brief list of a few.

Application: plastic mold, injection mold, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, PCB, ICT fixtures, countertop grinding pads, fixture molds, test racks, storage boxes and so on.

Comparative analysis of the performance characteristics of bakelite and epoxy boards

Epoxy board and bakelite board are insulating materials in the more common, bakelite board insulation performance, does not produce static electricity, wear-resistant, high temperature resistance, in the PCB drilling and silicone rubber mah will be widely used, but also metallurgical tools, switchboards, electrical machinery parts of the commonly used materials; and epoxy board it, the most common is the 3240 epoxy board and FR-4 epoxy board, such as halogen-free FR-4 epoxy board has high Mechanical properties and dielectric properties, good heat resistance and and processability, low water absorption is not easy to deformation, the line is different, also determines the application of epoxy boards, halogen-free FR-4 epoxy boards are mainly used in electrical machinery and electrical equipment in the insulating structure of the parts, FPC reinforcing plate, electrical insulation, carbon film boards and so on.

The following is a comparison of the main performance characteristics of bakelite and epoxy boards:

Bakelite board at room temperature with good electrical properties, good mechanical properties, specific gravity 1.45, warpage ≤ 3 ‰, with excellent electrical, mechanical and processing properties. Paper Bakelite is the most common laminate, is also the world's most widely used, the largest number of industrial laminates.

Main characteristics:Good mechanical strength, anti-static, intermediate electrical insulation, is made of insulating impregnated paper impregnated with phenolic resin, baked, hot pressed and become. The product is suitable for use as insulating structural parts in electric motors and electrical equipments which require high mechanical properties, and can be used in transformer oil. With good mechanical strength, it is suitable for pads for drilling in PCB industry, distribution boxes, jig boards, mold cleats, high and low voltage wiring boxes, packaging machines, combs and so on. Suitable for motor, machinery mold, PCB, ICT jig. Molding machine, drilling machine, table grinding pads.

Application characteristics of epoxy board

Various forms. Various resins, curing agents, and modifier systems can be adapted to almost any application that requires a form that can range from very low viscosity to high melting point solids.

Ease of curing. With a variety of curing agents, epoxy resin systems can be cured at temperatures ranging from 0 to 180 degrees Celsius.

Strong adhesion. The presence of inherent polar hydroxyl and ether bonds in the molecular chain of epoxy resins gives them high adhesion to various substances. Epoxy resins have low shrinkage during curing and produce low internal stress, which also contributes to high adhesion strength.

Low shrinkage. The reaction between the epoxy resin and the curing agent used is carried out by a direct addition reaction or a ring-opening polymerization reaction of the epoxy group in the resin molecule, and no water or other volatile by-products are released. They show very low shrinkage (less than 2%) in the curing process compared to unsaturated polyester resins and phenolic resins.

Mechanical Properties. The cured epoxy resin system has excellent mechanical properties.
