At KINGBROTHER, we serve diverse industries with ISO9001/ISO14001/ISO13485/IATF 16949-certified quality systems. Our advanced quality assurance, including SPC, MSA, FMEA, APQP, and PPAP, ensures we meet the strict standards of over 15,000 R&D customers. Every PCB undergoes 100% E-testing and AQ checks, with reliability tests for high voltage, thermal cycling, impedance control, solderability, and more.
PCBs play a critical role across various industries. In artificial intelligence, they support advanced computing and data processing in AI systems. In the medical field, PCBs are vital for precision devices like diagnostic tools and wearables, adhering to strict safety standards. For the power sector, they handle high currents and voltages in systems like power supplies and renewable energy. In communication, PCB boards enable high-speed data transfer and reliable communication in networks and devices. Lastly, in industrial control, they provide precise control in automation systems and robotics, ensuring efficiency and durability in harsh environments.

We have advanced PCB board manufacturing technology and equipment to produce various types of printed circuit boards, including Multilayer PCBs (up to 68 layers), HDI PCBs, Rigid-Flex PCBs, and High-frequency PCBs.
To ensure that a PCB design is suitable for manufacture, our design services follow Design for manufacturability (DFM) guidelines, conduct a Design Rule Check (DRC), and provide clear Gerber files to the manufacturer. We also consider trace widths and layer stack-up and avoid difficult-to-produce features.
Common surface finishes include hot air solder leveling (HASL), immersion tin, immersion silver, electroless nickel immersion gold (ENIG), organic solderability preservative (OSP), and lead-free HASL. Each finish has specific properties and is chosen based on application requirements, cost, and environmental considerations.
We utilize various testing methods to guarantee the quality of our products before they leave our factory doors. Our testing services include the functional circuit test (FCT), in-circuit testing (ICT), automated optical inspection (AOI), and environmental testing.
In addition to conventional FR-4 high-layer count boards, we also have capabilities in manufacturing uneven-thickness rigid-flex combinations, high-speed high-layer count, high-density interconnect, substrates, semi-substrates, thermoelectric separation copper baseboards, high-frequency laminated, high-frequency high-thermal conductivity, and embedded types (embedded resistors, embedded capacitors, embedded diodes, embedded copper, embedded magnets, etc.) product processing technologies.
