1. Product introduction

The WH-2000B vacuum thermocompression bonding machine is a bonding machine independently developed by Wenchuan Co., Ltd. with independent intellectual property rights. On the basis of WH-2000A, the temperature control range has been increased, and the temperature control setting program has been upgraded. It is used for glass, It is the first domestic special equipment for silicon-based thermocompression bonding for the low-to-medium temperature bonding of silicon wafers, wafers, sapphire, quartz and other substrates.

The WH-2000B vacuum thermocompression bonding machine is sufficient to meet the low and medium high temperature bonding under different gases, and even the continuous low temperature under the vacuum environment; among them, the temperature during low temperature high bonding and medium low temperature can be flexibly set and programmed; The combined pressure is also arbitrarily set and controlled within the variable.

1.1 Product features

1) Using constant temperature control heating technology, precise temperature control;

2) Aluminum alloy working platform, flat top and bottom, fast thermal conductivity and uniform thermal conductivity;

3) Large heating area, covering sheets of commonly used sizes;

4) Air cooling, uniform cooling rate, which helps to ensure the bonding effect;

5) The pressure is precisely adjustable, and different pressure controls are substituted for different substrates;

6) A unique vacuum hot pressing system is adopted to greatly increase the bonding power while ensuring that the sheet is not damaged.
