A suitable PFPE fluid for your process in the electronics and semiconductor industry?

You make tomorrow’s technology, today. We see that the demand for chips is rising and processes in the semiconductor industry are becoming more challenging due to stricter requirements and higher quality standards. This also applies to your process fluids. Take for example the rising temperatures in wafer fabrication. Heat transfer fluids therefore have to meet an increasingly wide temperature range. Read here how our fluids help you meet higher quality standards!

Heat transfer processes

Accurate control of temperature is one of the challenges in heat transfer processes. But preventing corrosion and ensuring good compatibility between the various materials in your process are also very important. If you do not take these aspects into account, you will damage the parts because of overheating or corrosion.

A wide temperature range, good corrosion protection and a broad material compatibility are therefore requirements for your process.

For this purpose, we offer Galden® HT PFPE fluids. The fluids have been specially developed for heat transfer processes and have the widest temperature range in their class. In addition, Galden® has good compatibility with all kinds of standard materials and a low specific gravity.

Vapor phase soldering

With vapor phase soldering the boiling temperature and material tolerance of the vaporizing liquid play a major role in your process. If the boiling point of your liquid is too high, the components on your PCB become too hot and melt. If your liquid is not compatible with certain materials in the electronics, a chemical reaction will occur. You also need to ensure that no corrosion occurs as a result of contact with oxygen.

To make your soldering process successful, we offer Galden® LS/HS PFPE liquids. Suitable for vapor phase techniques like Ball Grid Array (BGA) and Package on Package (POP). Galden® LS/HS offers an extremely wide temperature range (up to 260°C) and has precise vapor temperatures. This prevents it from overheating! In addition, Galden® is compatible with various materials and safe to use. This is because Galden® has no flash point and is therefore not flammable.

Tests

Thermal shock testing

In the electronics industry, electronic components are tested for sudden temperature fluctuation through thermal shock testing. We understand that you are dealing with extreme temperature changes, from very low to very high temperatures. In addition, a chemical reaction on the electronics is not desired and the electronics should not be affected during testing.

 

Hermetic sealing tests

Leak tests are applied to electronic components to measure hermetic tightness. The leak test contains detection/indicator fluid which makes any leaks visible, because of course you want to prevent damage by moisture penetration!
When choosing the right detection fluid, you must take into account that your detection fluid does not evaporate, does not damage your electronic component and does not cause a short circuit or an explosion.

Galden® D PFPE liquid is ideally suited for both testing methods. In fact, Galden® D fluid takes into account all critical aspects of testing. The wide temperature range, high boiling point and low evaporation loss ensure that Galden® can withstand large temperature changes and does not evaporate in the test. The good dielectric properties ensure that short circuit or explosion with the electronic device is prevented.

Contact protection

Contact protection is widely used on electronic contacts and switches. Aspects such as current strength, various temperatures, material compatibility, and prevention of wear debris and oxidation come into play here. You want to prevent wear debris from forming as a result of wear on your switch. This is because wear debris prevents current flow when the contacts are closed. With contacts open, the wear debris causes circuit resistance problems.

For good contact protection, the lubricant must have:

  • Proper film strength
  • Wide enough temperature range
  • Ability to stay in place (prevent wear)
  • Viscosity that matches the contact force of the switch
  • Oxidation resistant properties
