SMT Production

SMT Production
DFM design optimization
Our engineering team has extensive experience in identifying potential process risks during the design phase, helping customers avoid subsequent production problems.
Prototype to Mass Production
We are flexible in accepting orders and can meet your needs, whether it is a small batch trial production or a large batch production.
Turnkey to Consigned, Flexible for Every Need
We can manage the entire process, from parts procurement, manufacturing, assembly to testing, and deliver complete products that are ready for immediate use. Alternatively, you can provide the materials according to your needs, and we will focus on high-quality production.
Full-Scope SMT Production
Material and component inspection
All materials and components undergo strict quality inspections upon arrival, including size, pin/pad inspection, and inventory tracking
Solder paste printing
High-precision solder stencil and solder paste supply systems are used to ensure solder paste thickness and coating uniformity, avoiding bridging or insufficient solder joints
Mounted components
Using multiple high-speed automatic placement machines, we can mount fine-pitch BGA, QFN, 0201 and other tiny packages
Reflow soldering
Precisely control the temperature curve to ensure that all components achieve the best welding quality and reduce problems such as cold welding and biased welding
DIP Assembly
In addition to high-efficiency SMT processes, CHOWSONS is equipped with multiple DIP production lines to meet the needs of power modules, industrial controllers, and communication devices. For critical components such as capacitors and large transformers, the DIP process ensures unmatched stability and reliability.
Why Choose Us
