Double-Sided/Multi-layer PWBs
This PWB is made of conductive layers that are connected via copper-plated through-holes.
From general-purpose to special-purpose products, you can achieve both low cost and high quality by selecting optimal materials to suit your purposes.
Principal use
Computers / Industrial Machinery / Measuring Instruments
Technology / Composition
Thin/Thick PWBs
Demand for thin PWBs has increased, mainly for mobile purposes.
We can supply thin PWBs that reduce warping during chip installation.
To install heavy parts or large chips on PWBs, we can supply thick PWBs that are made of highly elastic or low thermal expansion materials.
Principal use
Low-Profile Modules / Mobile Terminal Apparatus / Medical Equipment
Technology / Composition
High Modulus/Low CTE PWBs
Warp can be remarkably reduced because of the small XY-axis expansion coefficient and high coefficient of elasticity.
An environment with a large temperature change may cause cracks in solder joints due to differences in thermal expansion coefficients, which reduce connection reliability. To prevent this, the thermal expansion coefficient of the PWB must be reduced.
The thermal expansion coefficient can be reduced to as low as that of alumina ceramics or silicones.
Principal use
Servers / Routers / Measuring Instruments / Communication Equipment / Semiconductor Packages
