High density Wood fiberboard for PCB Drill

  • Composition

    wood fiberboard 


           Composite forest products, or engineered wood. refer to materials made of wood that glued together. In the United States. roughly 21 million tons (21.3 million metric tons) of composite wood produced . The more popular composites materials include plywood, blockboard, fiberboard, particleboard. and laminated veneer lumber. Most of these products based on what were before waste wood residues. or little used or non-commercial species. Very little raw material lost in composites manufacture.

          Medium density fiberboard (MDF) is a generic term. for a panel composed of lignocellulosic fibers. combined with a synthetic resin or other suitable bonding system. and bonded together under heat and pressure. The panels compressed to a density of 0.50 to 0.80 specific gravity (31-50 lb/ft.3) . Additives may introduced during manufacturing to improve certain properties. Because fiberboard can cut into a wide range of sizes. and shapes, applications are many, including industrial packaging, displays, exhibits, toys. and games, furniture and cabinets, wall paneling, molding. and door parts.

           Also referred to as hardboard. a high density fiberboard (HDF) for flooring is a type of engineered wood product. It’s made from wood fiber extracted from chips and pulped wood waste. HDF for flooring is similar. but much harder and denser than particle board . or medium density fiberboard (MDF) for flooring. It has a density greater than 50 pounds per cubic foot or 800 kg per cubic meter. This makes for a perfect stabilizing material for laminate floors. and engineered hardwood flooring.
     

    fiberboard uses for wooden circui​t board Drill


          high density wood fibreboard used for medium or micro PCB drilling. Board planing is good and make sure that drill isn't wear and tear. hole quality improved as its Drilling. without Phi peak has better chip removal and cleanliness. It is the most affordable of the pad drilling.

           Wood fibre board made of wood fibres. which connected to each other through the effect of heat and pressure. The adherence of the fibres to each other achieved through couching. and the wood’s own adhering properties. The fibres on the surface layer of the board are often more ground up than those in the middle layer. This gives the board an even and compact surface. Glue and other additives can used to improve the properties of the board. and to even out differences in raw materials and manufacturing methods. The main raw material for fibre board is, but, wood fibre, and the amount of additives is usually less than 1%.

           Paraffin is  used as a water-repellent adhesive. Starch, artificial resin and hardening oil. used as binding agents to improve the strength. Veneering board, paper, fabric, plastic, woven glass fabric, metal. or cork used as coatings for wood fibre board



    high density fiberboard vs wood


          The category of composite wood products such as plywood. oriented-strand board (OSB), and particle board differ from fiberboards in several ways. Although these products also involve the use of wood particles (strands, chips. and coarse sawdust) in their manufacture. the way in which they combined tend to make them less stable under certain conditions. Plywood made from thin veneers of wood-strand mixtures layered. in sequences of right angles. Particle board is like fiberboard in. its compression processing of bonders and wood particles. yet the result is a less stable material that tends to crumble at cut edges. OSB is the most solid of these, yet these panels will break when rendered into standard 4x8 sheets.

          HDF is a very thin board, with a typical thickness of 2.5mm,2.7mm. and is also often supplied perforated. it is completely appropriate as a substrate for PCB drilling

    940*1245mm 1041*1245mm 1092*1245mm
     
          HDF (High Density Fibreboard/Hardboard) is like MDF in. that it is a man-made composite panel product. that manufactured from compressed wood fibres.

           It is a stronger, harder product than MDF with a typical density of up to 900kg/m3. HDF used in laminate flooring products where this density required. though other uses include door skins and underlayment.
     
          HDF is a very thin board, with a typical thickness of 3mm-8mm, and is also often supplied perforated. meaning it is completely inappropriate as a substrate for creating interior mouldings. 
     
          HDF-High Density developed for use where physical property integrity. and surface finish are important. The average density of more than 820 kg/m3 (51 lb/ft3) ensures high core strength and face density.
     
          HDF-High Density can substitute veneer cross bands in hardwood veneered plywoods. by providing a superior smooth surface to reduce potential surface defects. such as telegraphing of expensive, thin surface veneers. Its high internal bond is able to withstand most hot-press conditions.
     
          The high quality surface of HDF-High Density also makes an excellent. white board substrate allowing application of paint or laminate. In the electronics industry. the hard uniform properties of our 2.5mm (0.10 in) product perform well as backer board. in the printed circuit board (PCB) manufacturing process.
     
          As with all our products. you can also request 100% FSC (Forestry Standards Certification). wood used to make your high density panel.

  • Product Advantage

    high density wood for printed circuit Drill advantage


          The MDF market has grown in the United States over the past 10 years. Shipments increased 62% and plant capacity grew 60%. Today, over a billion square feet (93 million sq m) of MDF consumed in America every year. World MDF capacity increased 30% in 1996 to over 12 billion square feet (1.1 billion sq m). and there are now over 100 plants in operation.
     
     
    A, High surface density and hardness, low burrs;
     
    B, Small thickness tolerances, long service life of drill;
     
    C, Improve cleanliness of CCL by less debris at the moment of breakdown;

     
          The surface of MDF is flat, smooth, uniform, dense. and free of knots and grain patterns, making finishing operations easier and consistent. The homogenous edge of MDF allows intricate and precise machining and finishing techniques. Trim waste is also reduced when using MDF compared to other substrates.

           Improved stability and strength are important assets of MDF. with stability contributing to holding precise tolerances in cut parts. It is an excellent substitute for solid wood in many interior applications. Furniture manufacturers are also embossing the surface with three-dimensional designs. since MDF has such an even texture and consistent properties.


          Our HDF High Density products are. also available with low formaldehyde emissionsOther emission levels. can obtained to meet a range of formaldehyde emission requirements. ask your Sales Representative.

    High Density Fiberboard (HDF). is an engineered board produced from resin bonded wood fibers. under high pressure and heat. HDF is a non-load-bearing product for interior use in dry conditions. HDF.  due to its very fine surface. is suitable for different coatings veneering, laminating, painting and varnishing. HDF is available in a variety of thicknesses, and a sanded surface to one or both sides.
