Item Number: YLJ-VHP5-4
Transported by LTL Freight (Truck)

YLJ-VHP5-4 (update from EQ-VHP-5T-4) is a CE Certified electric vacuum lamination hot press designed for wafer bonding or thin film transformations up to 100mm x 100mm. It has the max. working temperature of 500ºC along with the max. the pressure of  20 Metric Tons.
Update: MTI YLJ series Pressers were CE approved on Mar. 2015



  • Two 135 x 135 mm flat heating platens made of  high-temperature resistant Cr steel with max. working temperature of 500ºC
  • 1000W Heating element is inserted into the center of the heating plates for fast heating
  • Max. Load on 135x135mm Heated Platen:
    • 10 Metric Tons at 500°C  ( 55 kg/cm2 )
    • 20 Metric Tons at RT   ( 110 kg/cm2 )
  • Two precision temperature controllers which control two heating plates separately with 30 programmable segments 
  • Water cooling jackets are built on the both top & bottom of the heating plates for assisting cooling

Hydraulic Pump

  • Modified electric hydraulic press is connected to a vacuum chamber.
  • Max. travel distance of the bottom ram: 15 mm
  • Automatic max. pressure controlled via a digital pressure gauge
  • Pressure accuracy: +/-0.01 Mpa ( 0.1 kg/cm²)
  • Two flat heating plates are installed with water cooling plates for Max. 500ºC working temperature
  • Max. opening of the pressing platen: 30mm
  • Water cooling  (>15L/min) is required to cool the heating plates when the operating temperature is over 200 ºC. 

Temperature control and Pressure Display

  • Two precision temperature controllers with 30 programmable segments control the heating plates separately with +/1°C accuracy. 
  • The temperature controllers have PID auto-tune function, over-temperature protection and thermal couple broken protection
  • Max. Temperature: 500°C with inert gas or vacuum with accuracy +/-1°C
  • Max. Heating rate:  2.5°C/min
  • Software and PC interface is built in the controller, which can be connected to a PC for computer controlling via a RS232 connector ( click picture left to see details )
  • Digital pressure meter ( controller ) is built outside the vacuum chamber. You can set pressure at the desired value which can stop the electric hydraulic press automatically            

Vacuum Chamber

  • Electric hydraulic press and heating plates are placed inside the vacuum chamber
  • Vacuum chamber is made of SS304 with the size: 525Lx480Wx450H (mm)
  • Vacuum chamber Capacity : about 75 Liters. 
  • 300mm dia. vacuum sealed  hinged type door with 150mm Dia. quartz glass window is installed for easy sample loading and observation
  • Silicone O-ring can be used for all vacuum sealings 
  • One precision digital vacuum gauge ( 10E-4 torr ) is installed on the vacuum chamber
