  • Product Advantage

    Aluminium Entry plate for PCB Advantages

    1. Aluminium Drill Entry Sheet can protect the circuit board against scrapes and pressing marks.

    2. Aluminium Drill Entry Sheet enhances the nicety amount of the drilling placement. It creates the drilling have assistance to ensure that the drill functions  without deflection.

    3. It significantly lengthens the life span of the drill little bit. Its particular alloy composition will keep the cleanness and the cooling of the drill little bit. Whats more, it really is an excellent conductor of warmth so it helps prevent overheating of the drill little bit and it can prevent the oxidation of the top.

  • Composition

    High density pcb drill exit board is a high density wood fibreboard with no added resin, ideally suited as an exit material for drilling and routing single sided, double sided and multilayer printed circuit boards.

  • Description

    Thickness and Tolerance 2.5 +/-0.2mm
    Density >980 Kg/m3
    Bending Strength >45 N/mm2
    Warpage <1 mm/m across the diagonal Delivery Specification
    High density pcb drill exit board is supplied in cut panels and position hole to customer requirements

  • Product Advantage

    • Excellent flatness and thickness tolerance
    • Homogeneous high density core provides for good cleaning and cooling of the drill bit
    • offers a uniformly smooth surface providing good face to face contact with the PCB giving good burr control through a wide range of drill diameters
    • Can be ‘flipped’ and used on both sides, maximizing utilization and material yield

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



(37”,41”43”)*49 size ,one pallet with 200pcs and 24 pallets in 1*20GP container.

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.
