Company Overview
Topoint Technology was founded in 1997 and listed on Taiwan's OTC market in 2000 (ticker: 8021), with its headquarters in Tucheng, New Taipei City. From the outset, the company focused on the R&D and manufacturing of PCB micro drill bits. Over more than three decades, it has transitioned from consumer electronics PCB processing to the ultra-fine, ultra-high-precision micro-drill segment required for AI servers and advanced packaging ABF substrates. Today, Topoint is one of the world's largest independent manufacturers of micro drills by production capacity, with 2023 revenue of approximately NT$4.2 billion, of which over 95% comes from drill bits and router bits.
In the AI industry chain, Topoint has secured a critical position in the "computing hardware manufacturing consumables" segment—after AI chips (GPU/ASIC) are stacked with HBM, they must be connected to the system motherboard via ABF substrates. Given the extremely high layer count (20–30 layers) and signal density of these substrates, tungsten-cobalt alloy micro drill bits are required to drill hundreds of thousands of micro-vias with diameters of 50–100 μm. These drill bits are extremely high-frequency consumables—each is scrapped after drilling tens of thousands of holes. Therefore, the explosive growth in AI shipments directly drives demand for Topoint's products.
Apex's core product is tungsten-cobalt alloy micro drill bits with diameters ranging from 0.05 to 0.30 mm. By application, they are categorized into standard PCB drill bits, high-aspect-ratio drill bits (for HDI and substrates), and ultra-micro drill bits (for ABF substrates). Key technical parameters include:
- Aspect ratio: up to 45:1 (drill bit diameter/length), capable of machining deep holes in substrates with more than 20 layers
- Drilling life: each drill bit can drill 3,000–15,000 holes (depending on board thickness and material), 15%–30% longer than competing products
- Breakage rate: <0.3% (industry average: 0.5%–1%)
Customers cover the world's top ten substrate manufacturers (AT&S, Ibiden, Unimicron, etc.), with revenue from ABF substrate customers rising from 15% in 2020 to 35% in 2024.
Routing solutions paired with drill bits are used for profile forming and edge trimming. In 2024, the DynaCut series of routers was launched, featuring nano-coating and a 20% improvement in tool life over the previous generation.
Provides drilling parameter optimization software and tool wear monitoring systems to enhance customer stickiness.

## Technology Moat
### Moat 1: Tungsten-Cobalt Alloy Formulation and Micro-Drill Geometry Design
Topoint has developed over 100 proprietary tungsten-cobalt alloy grades, adjusting cobalt content (6%~12%) and grain size (0.2~0.5μm) for different substrate materials (high-frequency high-speed materials, BT/ABF resin). Combined with finite element simulation-optimized drill point geometries (e.g., four-facet point angle, helical flute cross-section), the drill achieves an optimal balance between chip evacuation capability and cutting force. The accumulation of this domain Know-how requires over a decade, making it difficult for latecomers to replicate quickly.
### Moat 2: Full-Chain Precision Manufacturing and Quality Control
From blank raw materials (tungsten carbide powder), compounding, pressing, sintering, grinding, to coating, Topoint controls the entire process. Its proprietary "laser-assisted grinding" process controls drill cutting-edge roughness to Ra<0.1μm, reducing drilling burrs. In quality control, every drill undergoes high-magnification image inspection and dynamic balance testing, achieving a defect rate below 200ppm. These capabilities enable Topoint to meet leading substrate manufacturers' "zero-defect" delivery requirements.

Topoint has established joint laboratories with leading substrate manufacturers such as AT&S and Ibiden, participating in drilling solution R&D for next-generation substrates (e.g., mSAP process, glass substrates) 12~18 months in advance. This "Co-development" model creates extremely high customer switching costs, forming a deep cooperation barrier.

| Dimension | Data |
|------|------|
| Global Micro Drill Bit Market Size (2023) | Approximately NT$6.5 billion (PCB + substrate) |
| Topoint Global Market Share (by production capacity) | ~18% |
| Industry Ranking | No. 2 (second only to Kinzo Seiko at ~22%) |
| Major Competitors | Kinzo Seiko (China), Union Tool (Japan), Huitte (Japan) |
| Downstream Customer Concentration | Top 5 customers account for approximately 45% (all Tier 1 substrate manufacturers) |
**Competitive Landscape Characteristics:** The micro drill bit industry exhibits an oligopolistic market structure, with the top four manufacturers accounting for approximately 70% of global production capacity. Topoint and Kinzo jointly hold a combined market share of over 50% in the ultra-micro drill segment (diameter <0.1mm), representing an extremely high technological barrier. New entrants must overcome three barriers—alloy formulation, manufacturing precision, and customer qualification—requiring a minimum lead time of 5 years.

## Financials and Growth
| Metric | FY2023 | 2024 Q1-Q3 (Cumulative) |
|--------|--------|--------------------------|
| Revenue | NT$4.23 billion | NT$3.86 billion |
| Gross Margin | 41.2% | 42.5% (driven by premium product mix) |
| Net Margin | 18.5% | 20.1% |
| Core Growth Logic | ①AI servers drive doubling of ABF substrate drilling demand; ②Each GPU substrate requires hundreds of thousands of drill holes, with hole density increasing 15% annually; ③Capacity utilization rose from 70% to over 90%, significantly improving marginal profitability |
**Growth Drivers:**
- **Surge in AI computing hardware shipments**: In 2024, NVIDIA H100/B200 and AMD MI300 series combined shipments exceeded 4 million units, each requiring approximately 6–8 HBM packages, correspondingly increasing ABF substrate area and directly driving micro-drill consumption.
- **Product mix upgrade**: The share of high-value ABF drill bits rose from 15% in 2020 to 35% in 2024, lifting overall average selling prices.
- **Capacity expansion**: Topoint expanded production capacity by approximately 20% in Taiwan and Vietnam during 2023–2024, with an additional 1 million drill bits per month in capacity expected in 2025, fully aligned with AI order demand.Key Risks:
- Downstream Demand Cycle Volatility: If AI capital expenditure slows, substrate manufacturers' expansion plans may be delayed, leading to a decline in drill bit demand growth.
- Raw Material Price Risk: Tungsten carbide and cobalt powder prices fluctuate with international market conditions (the 2023 cobalt price decline was actually favorable); if raw material prices surge significantly, gross margins will face pressure.
- Technology Substitution Risk: If non-mechanical drilling technologies such as laser drilling and plasma etching achieve mass-production substitution in ABF substrates, they could disrupt the micro drill market—however, in the short term (3–5 years), mechanical drilling remains the most cost-effective solution.
- Geopolitical Factors: Tipoint is a Taiwan-based company, and US-China technology competition may affect its collaboration with mainland China PCB manufacturers.
Core Investment Thesis / Industry Value Summary:
"The essence of the computing power race is a manufacturing race, and manufacturing cannot do without every single micro drill." Tipoint has secured a position in the consumables segment essential to AI chip packaging, with exceptionally high certainty of benefiting from the trend. Its technological moat (alloy formulation, geometric design, customer lock-in) ensures it maintains approximately 20% market share in the micro drill market while continuously expanding the proportion of high-end products. If AI server shipments increase by another 50% in 2025, Tipoint's revenue is expected to exceed NT$6 billion, with net profit compound annual growth rate surpassing 30%. It represents a "high-barrier, high-certainty growth" hidden champion within the AI industry chain.
