Sagami PCI Co., Ltd.

We have a track record in Japan and abroad in the field of printed wiring boards.

We are an electronic part and device manufacturer established in 1969. We are engaged in drilling, laser processing, and outline machining of printed wiring boards, and we also handle processing, drilling, and polishing of difficult-to-machine materials. We have many customers in Japan, such as CMK, Meiko, Elna, and Kyocera. We have experience in delivering our products overseas to Seagate and Western Digital. Our company has been satisfying requests for printed wiring boards and increasing our business volume under a system operating 24 hours a day, 355 days a year. We have confidence in our machining technologies. We have drilled holes as small as diameter 0.1 mm in mass production and diameter 0.075 mm in trial manufacturing.


Other presentation

[Company strength]
Our company handles any kind of board-related processing under a system operating 24 hours a day, 355 days a year. We conduct joint research on newly developed products and small-lot production at the trial manufacturing level at our HQ technical center, where our advanced technologies are concentrated. We conduct mass production at four factories in Japan under a quick and complete system. We also support through-hole conductive plating for multilayer boards and double-sided printed wiring boards in collaboration with a company specialized in plating. We provide completed board assemblies by incorporating the plating process. We repair the defective boards if a multi-board sheet has one or two defective boards to save the remaining good ones. This repair business remarkably improves board production yield and contributes to cost reduction.

[Business description]
We are a proposal-type specialist manufacturer. We provide high-accuracy, high-quality drilling, laser processing, and outline machining services for printed wiring boards, at a quick turnaround and low cost. Recently we have been able to do business with customers in various industries other than printed wiring boards by evolving and developing the machining technologies we have been cultivating for many years. These include printed wiring board drilling and outline routing, printed wiring board regeneration (PCB Rescue), lapping and polishing carrier manufacturing and sales, processing difficult-to-machine materials, and drilling and polishing.

Electronic part, device, and circuit manufacturing

[Strength of products/technologies]
We continue to reflect our unique research results in machining based on the technologies that we have accumulated through our core business of drilling printed wiring boards. This is why our technology power for drilling is now rated as the top level in the industry. We have drilled holes as small as diameter 0.1 mm in mass production and diameter 0.075 mm in trial manufacturing. We always seek high machining accuracy in routing, and also beautiful machined surfaces. This is done by selecting optimal machining conditions and tools for the machining shapes and material characteristics. We customize our machines as required for machining. We can achieve high quality with laser processing in a broad range of diameters from 0.05 to about 0.4 mm.

[Representative's message]
Monozukuri craftsmanship continues to evolve all the time, and it is expected to be more reliable. We will continue our steady efforts to reliably satisfy such expectations for always providing highly reliable high-accuracy, high-quality products that exceed the technical standards in the industry. We will achieve this on the basis of machinery and equipment capable of delivering such products at quick turnarounds as well as thorough quality management. We hope that our constant efforts will help customers in a broad range of industrial categories and contribute to the realization of a rich society.

[Company structure for market development/overseas expansion]
We are increasing awareness of our technology power by participating in domestic Japanese exhibitions. Our Sagami PCI (Thailand) Co., Ltd. factory started work in February 2012 as an overseas manufacturing site.
