PCB backup board suppliers

08/07/2026

You're managing 3-4 different suppliers for backup boards, entry sheets, and lubricated aluminum.
Each with different QC standards, different paperwork, different delivery schedules.

What if one call covered all of them?

🔩 One BOM. One Supplier. One Contact.

Let me ask you something —

How many suppliers do you chase every month just to cover backup boards AND entry boards? Two? Three?

That's two sets of lead times to track. Two sets of documents to chase. Two people who might not reply on the same day.

There's a simpler way.

YUESHAN covers your entire PCB drilling material BOM under one roof:

🛡️ Backup Boards — HDF → UV melamine → phenolic. Every density from 880 to 980 kg/m³. Flatness ≤0.10mm, burr ≤0.05mm.

🥇 Entry Boards — Standard 1100 H18 aluminum → lubricated coated (cools drill bits by up to 30%) → back drilling alu for 5G/server work.

One example: our UV950 melamine-coated board saves 22% vs traditional melamine while matching the same 80 HD hardness. That's the kind of cost optimization a multi-supplier setup won't tell you about.

Why YUESHAN (in one line):
ISO 9001 · SGS/REACH/UL · 12-month warranty · Full TDS/MSDS · 12+ years exporting to India, Bangladesh, Saudi Arabia, Europe.

UV backup boards are priced 20% lower than Melamine boards, while delivering equivalent technical performance in hardness, flatness, and drilling CPK.
In addition, the UV board offers superior warping resistance, making it especially suitable for India's hot and humid climate. Key reasons include:
Low processing temperature (around 40°C), which prevents internal moisture loss and stress buildup.
A dedicated 3-day board conditioning process to stabilize moisture content and minimize post-shipping deformation.
This significantly reduces the risk of warping and drill breakage during PCB operations.
We also invite you to view our production line video (attached), which shows our dust-free environment, temperature-controlled facilities, and three-stage UV coating process that ensures consistent and reliable board quality.
Our UV boards are already verified and supplied to global leaders such as AT&S, SCC, and Foxconn.
