As a professional manufacturer deeply rooted in the global aluminum sheet export market, Haomei Aluminum leverages its years of industry experience to create highly adaptable aluminum sheet products specifically designed for PCB drilling applications. Based on the demands of the export market and strictly adhering to international standards, we use superior quality as our core competitiveness to provide global PCB manufacturers with stable, efficient, and reliable aluminum sheet solutions for drilling, helping customers improve production efficiency and reduce overall costs.
Our aluminum sheets for PCB drilling board use 1100 series industrial pure aluminum as the core material (preferred material). We can customize specifications according to the production needs of global customers. The core standard specifications are as follows: In terms of material, the 1100 series aluminum content is ≥99.00%, with high purity and uniform composition, making it the optimal material for PCB drilling and perfectly meeting various drilling precision requirements; the thickness range is 0.06-3.0mm, with common specifications of 0.15-0.20mm (H18 temper), and the thickness tolerance is strictly controlled within ±0.01mm to ensure dimensional stability during drilling; the size can be customized to standard export sizes such as 36″×48″, 40″×48″, and special sizes can also be adapted to customer production lines, with dimensional tolerance adjustable from ±0.5mm to ±3mm; the surface roughness Ra≤0.28μm (cross-milling direction), and the flatness ≤3mm/m, effectively avoiding drilling positioning deviations and suitable for precision drilling scenarios.
The core characteristics of the 1100 series PCB drilling entry sheet are deeply aligned with the core needs of PCB drilling processing, combining practicality and adaptability:
Firstly, excellent thermal conductivity: the 1100 series aluminum sheet has a thermal conductivity of 220W/(m·k), which can quickly dissipate the heat generated by the high-speed rotation of the drill bit, significantly reducing drill bit wear and extending drill bit life.
Second, balanced mechanical properties: Brinell hardness 20 HB, tensile strength 110-136 MPa, and moderate toughness, which prevents the aluminum plate from cracking and generating debris during drilling, while also reducing drill bit wear. This facilitates precision drilling operations.
Thirdly, it boasts outstanding surface quality. Through specialized passivation or anodizing treatment, the surface is free of oxide layers, scratches, and impurities, fundamentally preventing burrs and hole wall defects during drilling, ensuring a high PCB product yield.
Fourthly, it offers excellent electromagnetic shielding. 1100 series pure aluminum forms a natural electromagnetic shielding layer, suitable for high-frequency PCB drilling scenarios, effectively ensuring stable circuit performance. Fifthly, it is environmentally friendly and recyclable, complying with RoHS standards, aligning with global green production trends, and is reusable, further reducing customer production costs.
Quality is Haomei’s priority. Aluminum’s core competitiveness, and the foundation of our 1100 series aluminum drilling entry sheets’ global export market presence, stems from rigorous end-to-end control:
Firstly, strict raw material selection: We exclusively use high-purity 1100 series aluminum ingots, eliminating any impurities and ensuring the purity and performance stability of the aluminum sheets from the source. This completely avoids potential problems such as drilling deviations and aluminum sheet cracking caused by raw material issues.
Secondly, advanced production processes: Utilizing proprietary precision cold rolling and uniform annealing processes tailored to the characteristics of 1100 series pure aluminum, we effectively eliminate internal stress in the aluminum sheets, ensuring dimensional stability and minimizing batch-to-batch errors, thus meeting the large-scale continuous production needs of global customers.
Thirdly, a comprehensive testing system. Each batch of 1100 series products undergoes multi-dimensional specialized testing for flatness, thickness, surface roughness, and corrosion resistance, equipped with automated testing equipment to achieve full-process traceability. Salt spray testing shows no corrosion for ≥24 hours, and hole position deviation is ≤±0.05mm. Unqualified products are resolutely rejected for export.
Fourth, complete international certifications: 1100 series products have passed ISO9001 quality system certification and SGS environmental certification, meeting the standards of mainstream export markets such as Europe and the United States, and can pass customs smoothly without additional testing.
Fifth, longer service life: 1100 series aluminum sheets have superior toughness and wear resistance, allowing for multiple uses and extending drill bit life by more than 20%, effectively reducing customer production costs and offering significantly better value than similar products from competitors.
Our aluminum sheets for PCB drilling boards are widely used in drilling various PCB products, including single/double-sided PCBs, multilayer PCBs, and flexible PCBs. Specific applications include LED lighting, automotive electronics, communication equipment, new energy, and medical equipment. They can be used as PCB drilling covers to prevent drill bit indentations and scratches on the circuit board surface, providing positioning guidance; they can also be used as pads for rapid heat dissipation, cleaning drilling debris, and ensuring smooth hole walls. They are suitable for PCB processing of high-power LED lights, car chargers, 5G base stations, and photovoltaic inverters, meeting both high-precision drilling requirements and harsh outdoor and automotive environments. Currently, our products are exported to many countries and regions worldwide and have gained consistent recognition from global PCB manufacturers.
Haomei Aluminum adheres to the philosophy of “Winning the market with quality, expanding globally with service,” providing high-performance, cost-effective aluminum sheets for drilling to the global PCB industry through precise specification matching, excellent product characteristics, and stringent quality control. We can customize specifications according to customer needs, provide comprehensive export services, help customers enhance their core competitiveness, and work together to achieve win-win results in the global market.
