Epoxy De-gassing: When a two-part epoxy is mixed, it is very likely now filled with many small air bubbles. These bubbles MUST be removed prior to injection into a ferrule (production lines commonly use centrifuges or vacuum chambers to remove gasses /...
Almost all epoxies used in fiber optics are two-part and have dissimilar mix ratios.Purchasing bulk material requires the most amount of handling.The resin and hardener will have to precisely weigh out before mixing.Any mistakes here will lead to problems down the...
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: Build in buffer time –...
The most common fiber optic epoxy packaging is premeasured two-part packs.These take the precise handling out of your hands and decrease the time and amount of material you handle.This pack also increases your process control and usually has a simple divider with...
One way to characterize oven ports is by using a thermocouple probe inserted and potted with epoxy into a ferrule – just like when terminating a fiber, except you'll be inserting the thermocouple tip instead of a fiber.Cure it, as you would a regular...
Best Practice tips and techniques for epoxy burst pouch / burstable seal bi-packs.乐动官方网址You may want to save these tips – and refer to them when training your cable assembly production team.Here are instructions for burst pouch bi-packs (with notes for best...
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...
乐动官方网址Epoxies used in FO cable assembly production are carefully selected for their cured bonding properties—their ability to keep a strong fiber/ferrule bond during the service life of the cable assembly.During their lifetime, connectors are exposed to a variety of...
A dual asymmetric centrifuge is a mixer that combines centrifugal-type rotation (rotation around a point outside the sample holder) with rotation around the central axis of the sample holder. This combination of opposing forces enables rapid mixing of the...
One method to encourage bubbles to come out of the bulk material is a 2-stage heat cure.This is a short, initial cure at an elevated, but lower, temperature than the final cure.An example is a 50°C cure for 30 minutes, for a product that has a final cure at 85°C....
