Overview

As electronic devices become increasingly smaller and higher functionality, the precision processing technology required for electronic components is becoming an increasingly important factor in advanced technology industries.

In particular, the high-density integration of semiconductors and the expansion of small electronic devices such as mobile gadget have increased the demand for high-precision and high-density packaging of components.

In order to meet these needs, Maxell's precision electroforming technology EF2 (official name: Electro Fine Forming) is used to form patterns on SUS plates and Si wafers to provide precision electroformed parts in various shapes. Multi-layer electroforming technology enables us to produce a wide range of high precision parts such as nozzles and filters for inkjet printers, molds for electronic parts, micro gears, micro washers and structural parts for micro machines.
