PCB Assembly

PCB Assembly is our turnkey service integrating SMT and THT to deliver fully populated, tested, and packaged boards from bare PCBs and components. It includes solder paste printing, high-speed placement (up to XYZ,XYZ CPH), reflow/selective soldering via ERSA Versaflow, multi-stage inspection (SPI, AOI, X-ray, electrical), cleaning/coating, and final packaging. Our hybrid lines enable SMED changeovers, real-time control, and full traceability—ensuring ±25 µm accuracy, ≥99.5% yields, IPC-610 Class 3 compliance, and void-free joints across prototypes to high-mix volumes. Ready for reliable PCBA? Let's build it.

Manufacturing Metrics

All of our services have different metrics. We've aimed to unify and better present the capabilities of our manufacturing services through a standardized approach.

PCB Depaneling

All of the PCBs are assembled in arrays, which later need to be separated. Manual depaneling is carried out on smaller batch sizes and suitable PCB board layouts. A "pizza cutter" board separation device or by hand are both used to separate the boards. For larger batches, we use automated depaneling machines. Here is how it works: by scanning the data matrix on the PCB, the depanelizer automatically selects the right gripper and cutter for the design. Once the PCB arrives on the machine, it takes a picture of the fiducial markings and recalculates the cutting trajectory according to the actual position of the PCB. With the help of the fiducial recognition feature, the machine can cut with a stable accuracy of 100 microns. For even greater accuracy, a machine vision-aided cut inspection can be performed after the first cut to measure the actual position deviation of the cut. The cutter spins and cuts the panel from the bottom. It revolves at a angular velocity of 60 thousand rotations per minute to ensure a fast tact time and optimal dust extraction. To further prevent dust accumulation during milling, an ionized air stream is blown at the top of the PCBA, and a vacuum nozzle removes the lifted dust from the bottom. The air stream removes the effects of electrostatic dust adhesion, and the vacuum completely removes dust from the machine environment. During the cutting, a robotic hand with a gripper grabs the PCBA from above. Once the cuts are done, it carries them into a specifically designed tray.

Conformal Coating

To protect PCBs from harsh conditions while in use, we have conformal coating equipment. Conformal coating is a thin, protective layer applied to PCBs to safeguard them from various environmental factors. It is a crucial component in ensuring the reliability and longevity of PCBs, especially in harsh or demanding environments such as medical, industrial, or IoT industries. At our facility, PCB loading, coating, curing, and unloading are all fully automated and inline processes. We utilize a non-volatile UV coating that cures quickly in UV light. Precise coating coordinates identify spots that need coating or should be left uncoated. Numerous coating nozzles ensure accurate filling and application. The coating process is as follows: The appropriate conformal coating is chosen based on specific application requirements. Using dispensing equipment, the coating is applied according to patterns. After application, curing is performed through UV radiation, or a combination of both, to ensure optimal adhesion and protection. Finally, the operator checks the coating thickness using a coating thickness gauge. Having conformal coating equipment in-house helps us achieve flexibility and a faster turnaround time. This improves product reliability and allows us to respond quickly to partner needs or changes.
