Our Product Lines

Four Consumable Lines, One Supply Chain

Each product line is engineered to solve a specific drilling problem — not just deliver material. Choose by your board type, hole size and yield target.

01

PCB Backup Boards

Eliminate exit burrs and drill breakage. Flatness ≤0.10mm guaranteed. Stack up to 4 panels per hit for +50% throughput.

02

Aluminum Entry Boards

Burr-free drilling for standard vias. 0.18 ±0.015 mm plain entry sheets, oil-free surface — no panel contamination, no extra cleaning.

PCB Aluminum Entry Board & Lubricant Entry Sheet →
03

Lubricant & Coated Aluminum

Cool the bit by 30%. Reduce breakage on micro-vias below Ø0.15mm. Thermally stable Coated alternative at competitive cost.

Lubricant-Coated Aluminum Entry Board →
04

Back-drill Aluminum

Eliminate stub length variation on 5G & server backplanes. One-piece seamless design with retained edge — no repositioning between passes.

Back-Drill Aluminum HW600/HW900 →
Real Results

Measurable Improvements on Real Production Lines

These aren't lab numbers — they're field results from PCB manufacturers running YUESHAN materials on their HDI, multilayer and back-drill lines.

Signature Solutions

Engineered for the Toughest Drilling Jobs

Two flagship lines that solve the failures most lines fight: exit burrs, drill wear and stub scatter.

YUESHAN PCB backup boards
Backup Board Line

HDF · UV Melamine · Phenolic PHE

The support layer beneath your panel decides whether holes come out clean or burred. Our graded backup boards hold exit burr to ≤0.05 mm and keep flatness within ≤0.10 mm.

  • ▸ Hardness 70→90 HD across the range
  • ▸ Density tolerance tight at ±30 kg/m³
  • ▸ Raise stack height 2×→4 layers per hit
  • ▸ Proven on HDI, multilayer & IC substrates

YUESHAN coated lubricant aluminum entry sheet
Coated Aluminum Line

Thermoset Lubricant & L.C.O Alternative

A resin-lubricant film on the drill-entry face cools and lubricates the bit, cuts wear and tightens hole-position accuracy — especially for HDI, BGA and IC-substrate microvias.

  • ▸ 220°C thermoset stability, no melt rings
  • ▸ Engineered as an leading coated-aluminum alternative
  • ▸ Aluminum base ≤0.10 mm for sub-Ø0.15 mm vias
  • ▸ Stable CpK, uniform film thickness
