ablefilm cf3350
At NEDC, we cut epoxy preforms films regularly through die-cutting and laser-cutting. Oftentimes, our customers utilize a preform material they have used before. Ablefilm 5025E is a common material we see customers utilize. However, we also see customers utilize different preform materials when some needs are met:
Reasons to Try Ablefilm LOCTITE® ABLESTIK CF3350 Instead:
- Bigger Envelope Size is required that typical Ablefilm 5025E sheets don’t accommodate.
- Customers are looking for a lower price point to meet their internal goals.
- Are looking for a longer shelf life product.
- Are looking for ways to automate their process through bigger sheet sizes, increasing yield, and ability to keep machines/operators running longer.
When these needs are raised as a concern, a great solution is to utilize CF3350 Epoxy Film from Henkel Films as an alternative. CF3350 provides all of the great characteristics of 5025E, while also providing the 4 benefits above. Again, similar to 5025E, it comes with a silver filler package loaded into an epoxy bonding film. We have provided both datasheets below for ease of quick comparison. thin cross section circuit board
Case Study on a Switch to LOCTITE® ABLESTIK CF3350:
We had a customer utilizing Epoxy Bonding Film 5025E for years for many applications. However, their new project required a lower price point. We suggested LOCTITE® ABLESTIK CF3350 to help accommodate their goals. They were able to incorporate LOCTITE® ABLESTIK CF3350 into an ECO after doing internal testing with their circuit board/bonding process.
After prelimnary testing, and a review from engineeering they were able to lower their price point while trying something new.
