Samples
Sample1 Thin Film Circuit Substrate
Circuit boards based on vacuum deposition, photolithography and wet etching. Wide range of processing variations.
By selecting and combining the most suitable processing processes according to the required specifications from a wide range of processing variations, a high degree of design freedom can be achieved,
High-quality thin-film circuit boards can be supplied. We can also process supplied base materials and handle only certain processes.
Please feel free to contact us for more information.
Sample2 Thin-film side metallised substrates
Due to the increasing demand for high-density mounting of multiple elements as devices become smaller and thinner,
Building patterning technology for the sides of substrates such as high heat dissipation ceramic substrates such as alumina and aluminium nitride.
Circuit formation can be carried out on one to four sides.
Sample3 Thin-film circuit boards with thick copper
Thick copper pattern formation on fine ceramic substrates to meet the needs of high current and high heat dissipation.
Copper electrode patterns with thicknesses of up to 100um can be formed with fine pitch using thin-film processes.
Sample4 Metallisation for metal bonding and sealing
Thin-film metallisation process for the periphery of glass lenses and sapphire caps.
Formation of metallised films for highly airtight and reliable metal bonding and sealing with packages and substrates.
By using our metal trays with clamping function “CCMT”, not limited to the above applications,
It can also be used for metallising individual chips.
Sample5 Thick-film circuit boards
Circuit boards using screen printing methods. Based on past processing experience, the screens and pastes to be used are selected and the optimum specifications are proposed and products are processed according to requirements.
We select the screens and pastes to be used based on our past processing experience, propose the optimum specifications and process the product according to the customer’s requirements.
Compared with thin-film processes, the screen-printing method requires fewer labour costs and can be used in large lots at a lower cost, which is a feature of the screen-printing method.
Proudly introduce by us, please feel free to contact us for trial production.
Sample6 Circuit formation + Solder mask printing
Circuit boards with a solder mask pattern on the surface layer to prevent solder adhesion and ensure insulation reliability.
Fine resist patterns with stable film thickness can be formed by combining screen printing and photolithography.
Fine resist patterns can be formed with a stable film thickness by combining screen printing and photolithography. Solder mask printing alone is also available.
