What is EMS?

EMS (Electronics Manufacturing Service) is a service that undertakes manufacturing operations on behalf of electronic equipment manufacturers.
We mainly handle the entire process from circuit design, parts procurement, board mounting, product assembly, inspection, and shipping.
By using EMS, companies can bring high-quality products to market in a short period of time while reducing investment in manufacturing equipment and personnel.
Furthermore, our flexible response to high-mix, low-volume production and short delivery times, as well as our highly precise production system that utilizes specialized technology, will help reduce development costs and strengthen product competitiveness.
In recent years, the number of EMS companies offering total solutions, including design support and after-sales service, has been increasing, making them important partners in the electronics industry.

Marantz Electronics Manufacturing Quality

In addition to EMS (Electronics Manufacturing Service), we also develop, manufacture, and sell circuit board visual inspection equipment (AOI equipment).
We have established a unique system for improving quality in both manufacturing and inspection by introducing various inspection equipment, including our own high-precision AOI equipment and 3D SPI and AXI, into our production lines.
By utilizing our manufacturing know-how in the design of inspection equipment, we have built an effective inspection system that is more suited to the actual site.We have also introduced AXI equipment offline, and are working to create processes that prevent defects from being passed on to the next process.

The EMS industry requires not only quality assurance but also a system that can quickly identify the cause in the unlikely event of a defect.We record everything from the parts receiving lot to the manufacturing date, equipment used, and processing conditions to ensure detailed traceability for each product.
Even when a defect occurs, it is possible to identify the extent of the impact and take pinpoint measures, contributing to preventing recurrence and improving quality. We believe that ensuring traceability is an essential element in building relationships of trust with customers.
