Our Commitment to Quality
Committing to rigorous quality assurance measures to deliver products that exceed industry standards.
PCB Raw Material
Our PCB boards use genuine Grade-A materials, such as Jian Tao (KB) and Nanya (NY). Good dimensional stability after heating. Curvature of the board ≤0.75%, Not easy to deformation and plate warping; The copper coating on the hole wall has better adhesive force; no layered or drape in copper. Drilling Roughness ≤25.4UM.
Technology Standard
Standard copper PTH technic makes copper in vias reach 20-22UM. Even better than IPC class 2 requirement (via copper thickness 18-20UM). lesser risk of copper shedding in faults and holes when under high current or high temperature.
Solder Mask
High-quality solder mask inks from brands like Ronda are applied using a photosensitive process. Glossy ink, strong color. Solder resistance thickness up to standard 8-30UM. Help to achieve better filling via with resin and better adhesive force solder mask on your PCB.
Plating&Surface Treatment
Premium electroplating and surface treatment chemicals are employed to achieve a 100% yield rate. Lesser soldering problem, BGA solder risk, make sure copper in via, surface treatment has strictly control within IPC standard. The pollution and oxidation of the board surface, black nickel, abnormal nickel thickness, SCUM (shadow) and other problems are strictly controlled during the operation process.

Our PCB Fabrication Procedure
We adhere to the principle of prioritizing quality and service.
PCB production process
Pre – stack → Automatic sheets cutting →Inner pretreatment → lamination machine → Exposure →Developing machine → Layer etching → Drill machine → AOI testing → Solder mask ink → Silk screen → Detection → FQC → Packging
FPC production process
Engineering File Preparation → Copper Foil Drilling (PTH, Plated Through Hole) → Copper Plating → Pre-Treatment → Dry Film Lamination & Stamping → Exposure → Development → Etching → Film Stripping → AOI (Automated Optical Inspection) → Pre-Treatment → Coverlay Lamination or Ink Printing → Plating Pre-Treatment → Post-Plating Treatment → Surface Finish → Legend Printing → Electrical Testing → Laser Profiling → FQC (Final Quality Control) → Packaging & Shipment。

PCB FAQ
CAM350/Altium Designer/Genesis2000//PADS/GC-power.
Our company's engineering team offers free DFM analysis. All data will be reviewed and confirmed after production. If there are any issues, an EQ confirmation will be issued.
The electrical testing of PCBS mainly involves checking whether there are any open or short circuit issues on the PCB board and analyzing whether it matches the customer's design data.
CTI stands for Tracking Index, which is the voltage at which marks are left on the surface of a board when it leaks and burns. For conventional FR4 boards, the CTI value is PLC3, that is, 175<CTI<245.
For finished plate thickness less than 1mm, it can be controlled at +/-0.1mm. For finished plate thickness greater than 1mm, the strictest control can be +/-0.13mm. Normally, it is controlled at +/-10%. (Because the plates and materials such as pp have certain tolerances, and the chip tolerance close to +/-0.075mm).
How to order
