I'm curious to know how they perform in humid conditions. I've had problems with these on the user end, often in consumer electronics. The peel off and separate problem has usually occurred in high humidity with various types of clear overlays, not with other tapes due to loading issues.

Very good discussion about the challenges of bonding to low surface energy materials.  I appreciate the continued development of next generation adhesives to address this issue.

In addition to adhesive selection, surface texture on the component can also be modified to increase bonding ability.  In general a smoother surface will bond better than a textured surface.

I have had unfortunate experiences with some pressure sensitive adhesive applications. What happened is that the adhesive would initially adhere in what appeared to be a satisfactory manner, but after a few hours, or even a few days, it would peel off and separate. This was in applications with a constant loading, so there was a force tending to separate the connection. Non-pressure sensitive adhesives would function in the same application, but they are all a lot more time and effort, although often less costly.

So do the new types of adhesive solve this problem for me?

Mr. Rizzo, thank you for teaching me some things I didn't know about PSAs.

Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Conformal coatings present themselves as space-saving alternatives to enclosures for protecting the circuit boards of automotive electronics. They can also provide electrical insulation.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
The continued growth of wireless health is a near-certainty. And engineers will be the key to developing and advancing technology solutions.
