JPN Patent 5292556
WEL-Therm ® is complex material which materialize both highly efficient thermal conductivity and low coefficient of thermal expansion. Low cost and stable product supply is possible since rare metal, such as tungsten and molybdenum, is not used.
|Specificaiton /Size for production||500 x 500 mm|
|Total thickness||0.5～5mm *1|
|Core diameter||0.5～3mm *2|
|Thermal conductivity||lower than 280W/mK|
|Coefficient of thermal expansion||5～10ppm/K *3|
|Surface process||various plating is possible|
|Core layout||Custom design is applicable|
*1 There is a limitation for coefficient of thermal expansion according to the total thickness.
*2 Practical core diameter is φ1～2mm.
*3 More than 10ppm can be set.
