TECNISCO was established in 1970 as a processing service provider for precision components, taking advantage of DISCO Corporation’s cutting and grinding technologies. Since then, TECNISCO have developed and integrated our technology fields into a “Cross-edge” micro processing technology which crosses five leading-edge technologies such as cutting, grinding, polishing, metalizing, and bonding, thus supporting high-tech products in the industries of optical communication, industrial laser, AV/mobile, projector, automotive and medical devices.
Product list
Metal products
Metal diamond composites (Silver diamond)
Silver based diamond composites for advanced thermal management
this material features an excellent thermal conductivity and a relatively low thermal expansion that no past materials were capable of. long-lasting, reliable material beneficial for high power applications.
Microchannel cooler
New-structured microchannel heat sink leading to a longer life of the high power LD module
new-structured microchannel heat sink which gives the high power LD module a longer life. Complement effect between Cu and Mo and technology of inside channels make it low electric-resistant and CTE-matched with LD. Au coating on the inside of the channels results in the improvement in corrosion prevention.
High pressure Seamless microchannels
Original method of forming microchannels in single solid metal resulting in high pressure-resistance microchannels
most reliable high pressure-resistance microchannel product, microchannels in the single solid metal. The inside channels are completely coated by Au coating, leading to the improvement of corrosion-resistance. Thus, it can be used as an efficient thermal conductor with liquid/gas circulating inside. Also, it can be used a mixing device or analytical device in the biotechnology/medical industries by taking advantage of the high-pressure resistance.
Insulation type Cu-AlN-Cu submount
Cu-AlN-Cu composite-type submount with high thermal conductivity leading to the decrease in thermal stress to LD. Insulation type
This is a heat sink for high-power LD (Laser diode) modules. Three-layer composition achieves both high thermal conductivity and insulation quality. Control of Cu plating thickness makes the heat sink match with the LD, resulting in higher power and longer life of the LD module. Because pullback is not required on the critical edge area, it has a high degree of freedom in designing. Moreover, it can be applied to a variety of application by this freedom in design.
CuW submount
Heat sink with high electric conductivity leading to the increase in the LD module power
This CuW submount is used as a heat sink for high power LD modules. Alignment with LD, and sharp edge and control of warpage for effective thermal conductivity are available.
Redundant solder can be controlled in AuSn vapor deposition on the LD bonding area
Mounts / Carriers
With our “ Cross-edge ” technology, any type of carrier can be manufactured according to the customers’ requirements
Any type of carriers from C-mount to full-customized carriers can be manufactured according to the customers’ requirements. Our “ Cross-edge ” technology including cutting, plating, vapor deposition, and bonding, gives you a one-stop solution.
