Sales Pitch

SMT / Board processing
Taking SMT (surface mounting technology) as our core technology, we mount electronic components for a wide range of products, such as high-density circuit boards for communication devices and boards for medical devices. 
・ We can mount small chips (0402, 0603 size), BGA, and CSP. We can also, of course, perform reflow soldering in a nitrogen gas atmosphere using lead-free reflow ovens.  
・ We can mount on boards from size L50 mm x W70 mm to L510 mm x W460 mm. 
・ We have an extensive product quality assurance system, equipped with a 3D solder printing inspection machine, a mounting inspection machine, an X-ray inspection device and a replacement error prevention system for mounted components. We are also working on a thorough factory-internal system that includes static electricity countermeasures, temperature and humidity, ROHS10, and cleanliness management. 

Processing examples and use cases
We perform high-density/high-quality(0402) electronic component mounting for
・Large boards for communication equipment
