About SANSHO. MFG.
Hello everyone. Here, we would like to introduce what SANSHO. MFG. makes and the uses of those products.
What are we making?
At our company, we manufacture our main products, base-plates and electrode terminal-pins, by bending and punching metal sheets, including copper, using a press machine.
A base-plate (top right in the figure on the left) is a plate-shaped product with a thickness of 2.5 to 5 mm, and is mainly used as a heat sink for components. In the metal processing industry, processing soft and thick copper often results in unintentional deformation, making it a highly difficult process.
Electrode terminal-pins (bottom right in the left image) are products with complex shapes and a thickness of 2 mm or less, and are mainly used in circuits that require large amounts of power. Since distortion and dimensional deviation are not permitted, complex and highly precise processing is required.
Depending on the product, plating, resist resin printing, and resin molding may be performed after processing with a press.

What is it used for?
Our products are mainly used as parts of power semiconductors. Power semiconductors are semiconductors that can handle large currents and high voltages, and are used in inverters that convert DC/AC and change voltage and frequency.
For example, they play a role in precisely driving motors used in industrial robots and electric vehicles, and in regulating the electricity generated by renewable energy power generation facilities such as wind power plants so that it can be used in facilities and homes.
Power semiconductors are essential products for realizing energy conservation and zero carbon, which are some of the most important issues facing the world.

Where in power semiconductors are base-plates and electrode terminal-pins used?
The diagram on the left shows a simple cross section of a power semiconductor.
First, the base-plate is located on the outermost side of the power semiconductor. The role of the base-plate is to efficiently dissipate the heat generated when electricity is passed through the power semiconductor element. If heat is trapped in the power semiconductor element, it can damage the element and cause a breakdown or accident. There are also base-plates made of iron or aluminum, but copper has a better ability to dissipate heat, so copper base-plates are preferred in fields that require large amounts of power.

Next, the electrode terminal-pins are responsible for passing electricity through the power semiconductor. To transmit electricity, a metal wire bridges the power semiconductor element and the electrode terminal-pin. In order for this wire to bond strongly to the electrode terminal-pin, the surface of the electrode terminal-pin must be of high quality, free of dirt, scratches, and other abnormalities. In addition, because the electrode terminal-pins are used to connect with other components, precision is also required in terms of their dimensions, angles, and other shapes.
Conclusion
As we have explained, our company uses advanced press processing technology to deliver products that are essential to improving the global environment. In the future, we are aiming for various fields other than power semiconductors. To achieve this, we need your support, who have read this page up to this point.
We look forward to receiving your application.
