MANUFACTURING TECHNIQUE

We support the entrusted development with our know-how in many years. With our know-how which we have developed with semiconductor manufacturing experience of various package types, we appropriately meet the needs of customers. Please feel free to contact us.

01

Wafer Testing

We support electrical characteristic test (logic / LCD). We support low to high temperature tests.

02

Back Grinding / Dicing

Backside polishing

With a protection of wafer surface (front),
backside polishing polishes wafer backside to specified thickness.
We support for dividing wafer by backside polishing after wafer dicing.
* Available: ~ 300mm wafer

Laser grooving

Our laser grooving supports rigid board such as Low-K materials which are difficult to be grooved with blades.
* Available: ~ 300mm wafer

With laser grooving

▲With laser grooving

▲Without laser grooving

▲Without laser grooving

Dicing

Dicing is to make wafers, substrates, glasses, etc. into individual pieces.
With edge trimming, wafer cracking and chipping during backside polishing would be prevented.
*Available: ~ 300mm wafer

03

Back-end Assembly of LSI Devices

Die bonding

TCB(Thermal Compression Bonding)

We support high-density, fine-pitch assembly. By controlling the bonding height, we achieve stable interconnection quality.

TCB(Thermal Compression Bonding)

Molding

We select the molding according to the requirements such as transfer molding and compression molding.

04

Module Assembly

Surface mount technology (SMT)

We support the surface mount such as mounting micro chips. For a tiny area and high heat-dissipating area which are difficult to solder, we support with laser soldering machine. Also, we support the mounting of ultra-thin FPC on double-side. We select proper soldering from low-melting point to high-letting point according to the application.

Solder ball jet mounting

We support laser-based solder ball jet mounting. This method is suitable for fine-pitch components and enables reflow-less, flux-free assembly.

Fine wire batch soldering

We support batch soldering of ultra-fine wire cables. High-precision micro joining enables compatibility with AWG46 at a 0.2 mm pitch.

05

Final Test / Visual Inspection

Electrical test

We support electrical characteristic test (logic, LCD, module, imaging).

Appearance check

According to the needs of customers, we support appearance check with automatic inspecting machine and visual inspection.

06

Packaging / Delivery

Chip tray packaging

We support chip tray packaging with selecting good chips from the dicing completed wafer.
We support tray, tape and reel packaging.
