Setting up a new bonding process and need to establish the curing schedule or your production process is set but experiencing fiber movement and need to adjust curing temperature or time, here is a FOC TIP to validate your curing schedule:


Characterize the oven ports – If you thermally cure epoxy, you must characterize the oven ports. Note that you are not measuring the ambient temperature of the port; instead, you are measuring the temperature of the epoxy inside a connector.

Using a thermocouple probe potted in a ferrule is a great way to characterize oven ports, because this mimics the actual epoxy curing process for your product.

For example, let’s say your curing schedule is 100 degrees C for 10 minutes. That doesn’t mean you simply put a connector into a 100-degree oven for 10 minutes. The epoxy’s temperature is influenced by the mass of the connector, so it may take 2 or 3 minutes for the epoxy’s internal temperature to reach 100 degrees C. Your total curing time may be 12 minutes, not 10.
