Does dry ice bubble as soon as it freezes? MCOTI solves FTV’s stubborn problems with 3 tips_Product information_MCOTI

In the electronic manufacturing production line that pursues ultimate efficiency, low temperature adhesive (Low Temp Adhesive)It has become a key material for chip mounting and precision dispensing. However, a hidden "process killer" often catches engineers off guard - the FTV (Frozen Thawing Void) phenomenon.That is, after the glue has been stored and transported on dry ice (-70℃), it will appear during the temperature recovery process.Uncontrollable bubbles, leading to dispensingScattered points, broken glue, or even the entire batch is scrapped. This is not a simple operational error, but an inevitable challenge to the physical properties of the material. MCOTI goes deep into the mechanism to dismantle and end this problem for you。

FTVThe essence is the physical gap caused by the mismatch of coefficient of thermal expansion (CTE).

When the hose experiences a dramatic temperature difference of "ultra-low temperature storage → room temperature recovery":

• The colloid, hose wall, and piston rod have different shrinkage/expansion rates due to different materials.。

• Micron-level gaps occur between interfaces

• Temperature recovery too fast or improper operation, air invades the gap and cannot be discharged, and eventually solidifies into bubbles

The consequences are not just cosmetic blemishes

• short term:The dispensing amount fluctuates by more than ±10%, which directly leads to equipment calibration failure.

• long：There are stress concentration points inside the adhesive layer, which reduces the long-term reliability of the product (especially in the fields of automotive electronics and industrial control)

We not only sell glue, we also provideSystem solution，Turn yield fluctuations into stable output.

Source “prevention” – physical isolation

• CTEmatch：Customize the hose material to reduce the interface gap from the source.

• Double seal：Piston + tip double locking, shipped from the factoryX-ray full inspection。

Process “control” – refuse to rely on feelings 

key action	✅ Correct operation	❌ Wrong operation
Warming attitude	Leave it vertically (with the glue outlet facing down) ≥ 2H	horizontally/stacked
hand part	Hold the tail	Holding the tube body (body temperature interference)
Cold chain monitoring	Equipped with temperature recorder	Determine based on the remaining amount of dry ice

"Rescue" afterwards - low-cost recovery

What if there are bubbles?No scrapping required!

• Centrifugal deaeration:Completed the adaptation test for mainstream centrifuges on the market, ready to use。

• Performance commitment：For viscosity, strengthzero impact, compatible with mainstream devices.

3 tips for engineers

• Set standards：Write the temperature recovery SOP into the work instructions

• Preparation tools：Equipped with vertical reheating rack + centrifuge, minimal investment and huge benefits

• Choose a partner：Find suppliers who can provide process support rather than traders who just sell goods

Conclusion

FTVThis is a common problem in the industry, butYield loss is not inevitable。MCOTI is committed to transforming the uncontrollable "depending on the weather" into a stable "standard output" on your production line through digital technology and systematic solutions.Choosing MCOTI means choosing a technical partner who can work with you to overcome process bottlenecks and improve overall yield.MCOTI is committed to usingData technology, helping you achieve stable mass production.
