  • Product Advantage

    melamine  entry and backup board Advantages:

    1. It is a composite of the Melamine paper and wooden fiber board with high density. It is especially made to replace the Phenolic backup board. 
    2. It is difficult to distort.  The warping degree is smaller than the Phenolic paper backup board.
    3. It reduces the abrasion of the drill and lengthens the life of micro drill bits. 
    4. It can save the cost and it has more sizes. 
    5. It doesn’t pollute the environment.

        Drilling in PCB production is indispensable process and it can't be avoided for either electro-connection among layers or fixing elements. 
    The formation of pcb drilling burrs affects the PCB quality and ends up in deburring processes. The burrs created from drilling processes is onerous to get rid of and also the price of deburring is often substantial. 
    step-down of burr occurred in drilling method will scale back effort and time to get rid of burr. so the opening drilling and deburr method square measure thought-about as necessary processes to save lots of energy. 
    Since burr formation is powerfully associated with method conditions and drill pure mathematics, experiments were dole out to develop a Drilling Burr management Chart by variable feed, spindle speed and drill diameter and backup board material. 
        it tested that choose high density and hardness backupboard may be a sensible approaches to attenuate drilling burrs and to green the PCB drilling method.

  • Composition

    2.0mm Backing board for high speed pcb drilling machine

     a backing board designed for automatic cnc printed circuit board drill machine.
     recommended for drilling of high-tech micro printed circuit boards, multilayers and flex-rigid boards. 

    Ordering information: drill board is supplied in production ready cut panels in accordance with customers requirements. Panels can be supplied on request with tooling registration holes.

    Disposal backing board is free of phenolic resin and formaldehyde. backup board is non-toxic to mammals and fish. backing board is biodegradable. It may be burned, subject to local legislation, thus providing heat energy.

  • Description

    Precision PCB Drill machine Backing board 
    production technique
    Technical Data Thickness: 2.0 ± 0.15 mm
    Density: > 980 kg/m³
    Surface hardness: > 85 shore
    Warpage: < 0.5%
    Quality Assurance The consistently high quality of is assured by ISO-9001 manufacturing processes.
    Handling and storage : supplied in a moisture protective packing designed to provide a barrier against moisture absorption from the atmosphere.
    Drill board should remain in its original packing until use. Drill backing board should be stored under the same temperature and humidity conditions as in the working area. Rapid change of environmental conditions will cause warp. 

  • Product Advantage

    2.0mm PCB Drill Backing board 
    • excellent underlay board chipping and free flowing extraction properties means lower risk of flute blocking and drill breakage
    • Reduced friction causes less wear on drill cutting edges, improving drill quality
    • Reduced drill burr due to a smooth, hard and very thin overlay
    • No phenolic or resin content to contaminate holes
    • Excellent flatness and tight thickness tolerances
    • Suitable for all drill diameters
    • Usable on both sides without loss of quality because of symmetrical build-up unique to

As manufacturer direct sales, yueshan backup board sells with big price advantage, the price we offered are truly based on production cost but not from any distributors or vendors. Even some well-known online companies are actually reseller of China factory products, so why do not work with yueshan to save more ?

Notice below backup board price is for your reference only, which could be up and down from time to time due to raw material cost fluctuation in the market. Our MOQ shipping is 1*20GP, smaller quantity order will surely make the unit price increase a little bit. Some special CUT requirement for our job has to be negotiated before order.

WARNING:he quality pcb backup board,inner core is HDF it uses special melamine ,resin ,with superior hardness 80 +-5HD , totally straight, not curved. Flat, hard surface provides the minimization of burring, Due to good hole quality, when drilled, the inner wall -of the hall is less contaminated and suitable for -precise drill. Due to minimizing Burr and Smear, good in soft and -hard board. * Economically reducing the drill bit wear out .Many backup board distributors are misleading customers with lower priced softer wood lower hardness and density, As professional manufacturer , export to many well-known brand name in this industry, we suggest you checking our samples carefully and compare them with other vendors 'sample regarding the hardness, density & burring minimization, formaldehyde to ensure what you buy is worthwhile

The Forklift carries pallets one by one, and then the pallets are loaded in the container in a row skillfully.
Packaged cartoon boxes are neatly stacked on export pallets with all corner and sides well protected.
When the container is filled with pallets, close the door and seal the container. Write and remember the Seal No. and Container No.. Finally the lorry will take the container to the specified port.
