high quality Alu sheet for pcb

PCB Drill Lubrication Backup Materials

  • Composition

           With continuous improvement and development of society, the requirement on high precision of electronics is getting higher. The development of high-precision electronics proposes requirement on precision of PCB processing. Meanwhile, requirements on positional accuracy of drilling and quality within drilling of PCB become higher.

    As a kind of uniquely innovative entry board, high quality Alu sheet for pcb produced by yueshan can ensure optimal precision of all apertures for users in manufacturing industry of PCB.

          coated aluminum entry sheet  consists of pollution-free carrier plate and dedicated coating in our company, so the unique surface is easy for alignment and stability before the drill point enters base plate.

  • Description

    Usage of high quality Alu sheet for pcb
    •Coating side is upward and aluminum side is downward on PCB;
    •The height of drill point needs to be 1.5~4 times than its diameter for chip removal;
    •Being pasted above base plate, drilling under drill point is the primary contact surface;
    •Notice if tape is closely connected to cover plate;
    •No fold or scratch is allowed on cover plate.


  • Product Advantage

    Features of high quality Alu sheet for pcb
    ●Ensure the best accuracy 
    ●Effectively reduce incidence rate of broken needle
    ●Reduce blade abrasion of drill point

    ●Improve roughness of hole wall and reduce nail head

    Lubrication Laminated Fibreboard Backup Materials 


    The unique resin system offers low melting point lubricating characteristics,minimizes drill bittemperature rise and
    maximizes drill life. The resin system is water-soluble and easily removed during subsequent wet processing.

    Wood (90%), Adhesive, Resin


    white melamine backup board has a smooth matt white finish. A slight structure from the coating process can be seen but is only a visual effect that does not affect the usability.

    or ready to use cut to size panels with slots or registeration holes according to customers’ drawings.
    Environment Manufactured with MDF that satisfies E1 CLASS requirements defined in the European Standard EN 622-1 when analyzed according to EN 120 standard.
    For disposal local laws are to be obeyed.
    Packing and storage 

    Melamine Fibreboard Backup Materials is wrapped in a moisture protective packing and should remain in its original packing until use. It should be stored under controlled temperature and humidity conditions that are similar to those that surround the  production area. Rapid change of these conditions may result in warp.

  • Description

    Lubrication Fibreboard material Drill Melamine feature 

    backup board is a new type of composite drill backing board. The main features are drill bit cooling,lubricating and drillbit cleaning, guaranteed by a unique and patented engineered surface resin system.
    Reduced Drill Temperature - YUESHAN’s unique lubricated resin layer significantly reduces drill temperature, minimizing drill wear and thus minimizing heat related hole defects.
    Improved Hole Wall Quality - the lubrication of the drill, provided by the unique resin layer, significantly 
    reduces hole wall roughness and extends drill life.

    2.5mm lubrication melamine laminated board  is a product family of our Melamine Fibreboard Backup Materials.
    as long-standing  melamine board suppliers with Technical equipment and experience,YUESHAN have always guaranteed the same high quality of products.
    our white fibre board is especially manufactured for circuit board Drilling. The backup material is coated with melamine in a continuous process which leads to very good flatness in combination with perfect thickness tolerance and distribution.

  • Product Advantage

    Lubrication backup board offers

    - suitable for all drill hole size diameters

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
