 Yael-864 - Vacuum Oven

In 1994 ,the first special vacuum oven was designed and tested in cooperation with Motorola israel,followed by a second,FI., USA. Vacuum Oven for drying moisture sensitive components. Processes for drying moisture sensitive devices has been a problem issue for the manufacturing industry. Most manufacturers unreel and bake the devices at 125 °C and then re-reel the devices. Motorola Israel helped design a vacuum oven that allowed the whole reel of devices to be dried without removing the devices from the reel. In order to determine if the vacuum oven was a good alternative, an experiment was designed that compared the vacuum oven to a conventional oven set at 125 °C and a conventional oven set at 70 °C. It was concluded from this experiment that the vacuum oven is an excellent alternative to the conventional 125 °C oven.

 Advantages:

  • Faster than standard oven at 70 oC (temperature limited by the polystyrene material used for reels land tapes)
  • As fast as 125 oC baking process
  • Practically 100% uniformity throughout the reel, unlike conventional ovens
  • No coplanarity and electrostatic discharge (ESD) failures as with 125 oC baking
  • No inter-metallic film formed between the solder ball and the PCB carrier on Ball Grid Arrays (BGA), as with 125 oC baking
  • Remarkable quality with near absolute dry resulting devices after only 24 hours processing
  • Fully automated with PLC control, RS232, Modem, printer and computer communication capabilities (optional)
