Established in Foshan, YUESHAN focuses on PCB drilling backup boards including HDF, melamine, UV melamine and phenolic backup boards. We help PCB drill rooms compare flatness, moisture behavior, hardness, exit-burr control and drill wear before qualification. For entry boards and the wider PCB drilling consumables range, visit yueshanpcb.com.
Our Foshan production site manufactures PCB backup-board grades for routine multilayer and precision drilling. Buyers can compare the four core families in our PCB backup board selection hub before requesting samples for side-by-side drill-line qualification.

State-of-the-art manufacturing facility producing Melamine UV coated backup boards, HDF, and specialty boards
Core composition, coating, resin system and lot consistency affect what operators describe as tear-out, copper pull, warpage, resin gunk and premature tool wear. See how to choose a PCB backup board and compare actual drill results rather than density alone.

Incoming materials and finished boards are checked for the characteristics that matter on the drill floor: thickness, flatness, surface condition, moisture-related stability and lot consistency. For a failure-led check, see our exit-burr troubleshooting guide.

why us
A backup board should be qualified by what happens at breakthrough — not by a low sheet price or a single density number. We focus the buying discussion on repeatable drill-room outcomes:
2.5mm Melamine UV Coated Board
2.0mm Melamine UV Coated Board
Melamine UV Coated Backup Board is a high-density fiberboard with a UV-cured melamine coating. The UV process creates a super-smooth, moisture-sealed surface with excellent flatness and warp resistance, outperforming traditional melamine paper-laminated boards. full UV melamine backup board guide.

As a factory-direct seller, YUESHAN offers genuine manufacturer pricing on all Melamine UV coated backup boards. Our prices reflect production cost, not distributor markups. Work directly with the source and save.
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.

BUYER NOTE: A board that is USD 0.80–1.00 cheaper per sheet is not necessarily cheaper in production. Compare backup-board cost together with drill consumption, snapped micro-drills, scrap, rework and first-pass yield. Use our $1-per-sheet cost comparison to calculate cost per good panel before changing suppliers.
(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.
Start from the failure you see on the machine, then work backward to backing support, material, process and supplier evidence.
Match HDF, melamine, UV melamine and phenolic to hole size, stack, humidity and defect target.
Diagnose bottom blowout, copper pull and poor breakthrough support.
Separate grab/snatch, vacuum, tool wear, stack support and parameter causes.
Troubleshoot banana board, bowing, cupping and vacuum-leak complaints.
Compare sheet price with tooling, scrap, rework and cost per good panel.
Ask better questions about resin chemistry, heat ratings and supplier evidence.
Trace sticky residue, drill wrap, chip evacuation and heat-related symptoms.
Use the product pillar to compare HDF, melamine, UV melamine and phenolic grades.
