Quality Control

 

3D SPI

The new SPI can accurately detect the solder paste printing defects such as excessive/insufficient tin, missing printing offset, etc., to ensure the quality.

Online AOI

Newly updated AOI can accurately detect the mounting problems of components such as wrong parts, missing parts and reverse direction, and the welding quality.

3D X-ray

Inspect the solder situation of components, from three-dimensional, like BGA, and reproduce the internal structure in all directions without blind spots.

Smart First-Piece Tester

Test the first sample according to the production data to ensure that the sample quality and function are consistent, and ensure the project promoting smoothly.

 

Production Advantage

 

 

One-Stop Service

High-speed and high-precision reliability equipment, supporting testing and assembly production lines, providing one-stop PCBA OEM services for PCB manufacturing, SMT processing, stencil, components sourcing, DIP plug-in post welding, function test and final assembly.

Raw Material Guarantee

Adhere to guarantee the quality from the source, use the solder paste of Senju brand imported from Japan, purchase all electronic components from the original factory or the first level agent, and trace each material to the original factory to ensure the authenticity.

Quality Assurance

The production line is equipped with new SPI, AOI, 3D X-ray and First-Piece tester inspection equipment. During the production process, it will also undergo strict IPQC production inspection, QC manual inspection and QA delivery inspection to ensure that the delivered products are free of any quality problems.

Whole Process Follow-Up

Senior engineers and technical teams follow up the whole process of the project to solve various EQs in the production process of the project and ensure the best lead time.

Highly Cost-Effectivedelegation

From one piece to mass production, we can paste bulk materials, and the cost of each placement is as low as 0.0012 USD/point.

System Certification

Our factory has passed ISO9001, ISO14001, ISO13485, UL and other international quality management system certification, and the products meet RoHS environmental requirements.
