Mo60Cu40 Thickness1.5mm Molybdenum Copper Alloy Heat Sink Based Sheet For Microelectronics Packaging
1. Introdution Of Thickness 1.5mm MoCu Heat Sink Sheet:
Molybdenum copper substrate is a material widely used in the field of microelectronic packaging. It is composed of two metal materials, molybdenum and copper, and has excellent properties such as high strength, high thermal conductivity, and high reliability. Therefore, molybdenum-copper substrates have excellent thermal conductivity and good mechanical strength, and are ideal for manufacturing high-performance microelectronic packages. choose.
2. Size Of Thickness 1.5mm MoCu Heat Sink Sheet:
The specifications of molybdenum-copper substrates are usually described in terms of thickness and area. Generally speaking, the thickness is between 10-1000 microns, and the area is between several square millimeters and several square centimeters. During the manufacturing process, molybdenum-copper substrates usually need a series of processing and treatment, such as cutting, surface treatment, electroplating and so on. The selection and optimization of these processes has a significant impact on the performance and quality of Mo-Cu substrates.
