YUESHAN supplies PCB drilling consumables to Malaysian PCB, IC substrate and EMS lines: 1100 H18 aluminum entry boards in 0.15–0.28 mm selected by drill diameter, lubricant-coated entry aluminum for sub-Ø0.15 mm microvia, and backup boards from HDF 880 (75±2 HD) to Phenolic PHE (90±5 HD, decomposition above 220 °C). A Singapore-registered trading partner has bought 1100 H18 × 0.18 mm entry aluminum from YUESHAN continuously since 2017, with material serving an OSAT plant in the Philippines. Sheets 940 × 1245 mm and 520 × 620 mm, MOQ 100–200 sheets, free samples with TDS/MSDS, FOB/CIF to Port Klang or Penang.
Malaysia sits on the higher-value part of the regional electronics chain — substrate, advanced packaging and high-reliability EMS rather than only commodity boards. When a line runs IC substrate or automotive PCB, the drilling consumable stops being a throwaway item and becomes the variable that decides exit burr, hole-position accuracy and drill-bit life. This page shows how YUESHAN configures material for the clusters that actually build boards in Malaysia.
Malaysia is the world's sixth-largest semiconductor exporter, and the northern corridor — Penang, Kedah, Perak and Perlis — is its fastest-growing cluster. AT&S opened its first Malaysian IC-substrate plant in Kulim Hi-Tech Park, Kedah on 24 January 2024, a €1.7 billion (about RM8.5 billion) Phase-1 investment expected to create around 6,000 jobs, producing substrates for high-performance computing and AI devices. Batu Kawan Industrial Park in Penang hosts a dense concentration of electronics and PCB multinationals, and Intel has long-established operations in Penang. Further south, the Klang Valley and Greater Kuala Lumpur concentrate trading houses and regional procurement offices that buy on behalf of plants across ASEAN.

High layer counts and tight positional tolerance. Use UV Melamine 950 (83±3 HD) as backup with lubricant-coated entry aluminum for microvia work; HDF 880 (75±2 HD) covers the high-volume multilayer base load.
Substrate and interposer drilling needs the hardest, flattest support: Phenolic PHE at 90±5 HD, 1.50 mm, decomposition above 220 °C. See HDI & IC substrate solutions.
New capacity favours a repeatable exit surface across changeovers, so UV Melamine 880 or 950 keeps burr consistent without re-tuning job to job.
Buyers here consolidate for plants across the region. They need a locked spec, batch traceability and a transparent aluminum formula price they can pass through — the same model behind our Singapore trading-partner record.
| Build type | Entry material | Recommended backup | Why |
|---|---|---|---|
| IC substrate / interposer | 1100 H18 · 0.15–0.20 mm | Phenolic PHE · 90±5 HD | Highest hardness on the range; holds face above 220 °C substrate-drilling heat |
| HDI 1–2 step, sub-Ø0.15 mm microvia | Lubricant-coated aluminum (LCO) | UV Melamine 950 · 83±3 HD | Coating cools and lubricates the bit; sealed hard face holds microvia location |
| 12–24 L / back-drill | 1100 H18 · 0.20–0.28 mm | UV Melamine 980 + back-drill aluminum | Anti-deformation at tall stack; controlled stub depth |
| High-volume multilayer 4–12 L | 1100 H18 · 0.18–0.25 mm | HDF 880 · 75±2 HD | Best published cost-to-performance for Penang base load |
| Automotive PCB (thick copper) | 1100 H18 · 0.20–0.25 mm | HDF 880 or UV Melamine 880 | Cuts bit wear on thick copper, holds burr low |
| Flexible / thin panels | Thin 1100 H18 | UV Melamine 840 or kraft paper | Sealed melamine face resists the tropical humidity |
The entry board sits on top of the panel stack: it positions the drill on entry, stops the bit skating and — coated types — cools the bit. The backup board sits under the stack and supports the hole exit so glass fibre and copper are sheared clean instead of torn, which is the basis of exit-burr control and fewer broken bits. They are not interchangeable; a complete line needs both. New to this? Read what an entry board does and what a backup board does.
| Drill Ø (mm) | Recommended entry thickness (mm) |
|---|---|
| 0.20–0.25 | 0.15–0.20 |
| 0.30–0.35 | 0.18–0.25 |
| 0.40–0.45 | 0.20–0.28 |
Plain 1100 H18 covers holes of Ø0.15 mm and larger on multilayer and PTH work. Below Ø0.15 mm switch to LCO lubricant-coated entry aluminum. Background in the HDI drilling guide.
Penang and Klang Valley relative humidity routinely exceeds 80% for months. A wood-based backup board that absorbs moisture softens at the face — and the symptom shows exactly at the hole exit: more burr, less flatness, compressed stack height. It is the most overlooked cause of seasonal burr spikes.
Procedure detail is in the backup-board moisture guide; for cracked boards after drilling see backup-board snapping.
| Grade | Hardness | Thickness | Best for |
|---|---|---|---|
| HDF 840 | ~70 HD | 2.0 / 2.5 mm | 2–4 L, cost-first |
| HDF 880 | 75±2 HD | 2.0 / 2.5 mm | Standard 2–12 L |
| UV Melamine 880 | 80±3 HD | 2.0 / 2.5 mm | HDI 1–2 step · 12–24 L |
| UV Melamine 950 | 83±3 HD | 2.5 mm | HDI microvia, tighter tolerance |
| UV Melamine 980 | 80±5 HD | 2.5 mm | Back-drill · high layer count |
| Phenolic PHE | 90±5 HD | 1.50 mm | IC substrate / routing table |
| Sheet size (mm) | Sheets / pallet | MOQ (sheets) |
|---|---|---|

Cut-to-panel-size is available. Every lot ships with TDS and MSDS/SDS; COA by batch on request. Check load and stack height with the stack height calculator before a first order.

Yes. A Singapore-registered trading partner has bought 1100 H18 aluminum entry board at 0.18 mm from YUESHAN continuously since 2017 — over eight years — with the material going to a semiconductor OSAT plant in the Philippines. Multiple 2025 shipments closed with no quality claim.
Phenolic PHE — 90±5 HD, 1.50 mm, decomposition above 220 °C. It is the hardest grade in the range and holds its face under substrate drilling heat. Pair it with 1100 H18 entry at 0.15–0.20 mm.
By drill diameter. Ø0.20–0.25 mm holes use 0.15–0.20 mm entry; Ø0.30–0.35 mm use 0.18–0.25 mm; Ø0.40–0.45 mm use 0.20–0.28 mm. Standard alloy and temper is 1100 H18.
Plain 1100 H18 is fine for holes of Ø0.15 mm and above on multilayer and PTH work. Below Ø0.15 mm — HDI microvia, BGA, IC substrate — use lubricant-coated (LCO) entry because the film cools and lubricates the bit.
TDS and MSDS/SDS with every shipment, and COA by batch on request. Every lot goes through pre-shipment self-inspection — what a trading house needs to pass documentation through unchanged.
No. Aluminum entry board is quoted on a formula basis: SMM spot aluminum plus a processing surcharge, disclosed before order confirmation. A 2026 order from our Singapore partner triggered a roughly 9% formula adjustment, communicated in advance.
Two standard sizes: 940 × 1245 mm (300 sheets per pallet, MOQ 100 sheets) and 520 × 620 mm (800 sheets per pallet, MOQ 200 sheets). Cut-to-panel-size is available.
Free samples ship in 3–5 days with TDS/MSDS. Production orders are typically 2–3 weeks on FOB or CIF terms to Port Klang or Penang.
Yes. Back-drill aluminum is supplied for controlled-depth drilling and stub control on high layer count and high-reliability boards, usually alongside UV Melamine 980 backup.
