We mill PCBs with exact specifications, achieving trace widths as fine as 75 μm and hole diameters down to 0.15 мм.
Each board undergoes AOI (Automated Optical Inspection) и 100% electrical testing to guarantee accuracy, проводимост, и издръжливост.
With tolerances as tight as ±0,05 мм, we ensure your electronic designs perform flawlessly from prototype to production.
С върхова прецизност, we use CNC milling to shape circuit paths with exact control. This process removes copper and gives clean lines and sharp trace edges on every board.
Our machines follow your design closely with tight tolerances. We can adjust разстояние, дълбочина, and layout easily. This keeps each trace uniform and helps avoid signal issues.
PCB milling is ideal for prototypes or short production runs. You can test designs, Направете промени, and get fast results. It’s a reliable choice when speed and accuracy matter most.
We work with FR4, PVC, and GFK with copper. Each material is handled with the right speed and tools. This allows us to prevent пукнатини, edge damage, or surface defects.
Every board goes through a clean milling, пробиване, and final check. This ensures quality across each stage of the process. With Topsbest Precision, your boards are made to perform from the start.
Here are the key steps and principles we follow for PCB CNC milling.
We take a closer look at your design documents so that no details are missed. We measure pad sizes, hole location, and trace widths. This assists us in establishing the compatibility of the files with our CNC systems. This helps you to identify problems before they become serious, so your boards are of the right design.
We mill FR4, PVC, or GFK, with copper layers, which is chosen based on your needs. The material is clamped in its place to prevent sliding during milling. We then pre-program the CNC machine with the right tool paths and drill points, optimising it in speed and precision.
We use precision CNC machines to mill copper accurately to create the circuit traces. We maintain close tolerances to provide trace uniformity and clearances. Appropriateness of tools and their speed ensures that they do not damage them, but rather create clean edges and uniform surfaces.
Then we drill parts and vias as per spec. Fine features can be accommodated by drilling holes as small as 0.8 millimetres. The copper is preserved, and the board is held firm by clean drilling.
Once the boards are milled and drilled, we carefully clean them to get rid of the dust and dirt. We also remove edges and holes, deburr, and this avoids shorts and allows good soldering. This is a preparation step for the inspection and use of the boards.
Последно, we closely look at and inspect the board, the trace, the hole size, and the surface finish. Any imperfections are removed at visual and microscopic inspection. This allows us to deliver boards that meet our high standards. This ensures that you get excellent quality, dependable PCBs all the time.
We take care with every step of the PCB milling process to make sure your boards meet exact standards. From the start to the final checks, quality and accuracy are always our priority.
Our machines are capable of tight tolerances of up to +/-0.001 millimetres. This accuracy attains clean, dependable traces and fine details of your circuit boards. Surface finishes are also well managed to ensure the layers are not compromised and that electrical performance is upheld.
We use FR4, Rogers, and other specialised laminates. We have a highly competent workforce capable of utilizing the most appropriate milling techniques on the respective materials and using our multi-axis equipment, even complex board designs can be handled efficiently and uniformly.
We are guided by rigorous quality controls and trace all the parts throughout. With close oversight of the process, we can spot and rectify any problems early enough to make all the boards you receive reliable and ready to use
Topsbest Precision works with a range of materials suited for precise PCB milling and drilling. Our advanced machines and tools give accurate results for your electronic components.

We use multi-axis CNC machines to mill and drill PCBs with high precision. Our machines remove copper to create exact circuit patterns as per your diagram. The process gives you clean edges and accurate traces every time.
We work closely with your design to meet snug, тесни допустими отклонения. Our approach allows us to achieve consistent quality for all boards we make. Our CNC mills suit various materials and complex layouts. You receive reliable, high-quality PCBs designed to perform.
To make shallow cavities in the board, we employ pocket milling. These pockets are used in linking horizontal items in a secure position. They enhance insulation and spacing as well in tight spaces.
Pocket Milling comes in handy to shield RF and mechanical control. It can be more flexible on either a double-sided layout or a single-sided layout.
Milling preconditions the board for plating and via processing. We drill accurate holes and slots to perform through-hole plating and open vias. This adds a strong connection between layers.
Clean milling does not leave ragged edges. It preserves copper layers and flow. It also improves soldering and thermal ability.
Heat sinks are essential in power-intensive designs. Copper areas are shaped and milled into the PCB. These heat sinks remove heat from hot parts.
The correct thickness of copper and flat contact surfaces is regulated in milling. This serves to stabilize and make thermal management reliable.
The final board outline is shaped by using CNC milling. It forms precise разфасовки, слотове, and non-standard profiles. This can be applied in close-fitting housings and assemblies.
Stress points along edges are also removed by milling. This prevents the appearance of cracks. В резултат на това, you get a clean, functional finish.
We focus on the details that make a real difference. Every board is made to perform with precision, качество, and consistency from start to finish.
We make your design with tight tolerances on traces and holes. You obtain straight sides, clear lines, and regular spacing. Such accuracy facilitates a clear signal and dependable operation.
Our team provides flexibility in choosing the raw materials, включително FR4, PVC, and GFK, utilizing copper. Our machines handle a variety of layouts, from simple prototype designs to multilayer, сложни дизайни.
Once milled, we wash up every board and take the edge off. This is useful in soldering and makes the end board easy to assemble without other handling.
We have everything we do in a job designed to save time, but not at the expense of quality. Short lead time ensures that you receive working boards at the right time.
We can mill trace widths down to 0.15 мм. въпреки това, it depends on the material and board layout. For consistent outcomes, we recommend a minimum of 0.2 mm for high-density designs. Smaller features may be possible with review and tool adjustments.
We hold tolerances as tight as ±0,05 мм for milling and drilling. This control validates clean circuits, exact clearances, and proper hole alignment. It is especially critical for multi-layer or high-speed boards.
да, we support both. For double-sided boards, we use precise alignment methods to register each side during milling. This makes sure that vias, traces, and holes match across layers without shift.
We can prepare holes and slots for plating. За това, our team uses accurate drilling to meet your specs. Plating is handled separately. Although our process ensures holes are clean and ready for that step without manual adjustment.
We work with FR4, PVC, and GFK with copper. We choose the material depending on your design needs. Each material acts differently during milling, so we adjust speeds, емисии, and tooling to match. This helps us avoid edge chipping and delamination.
