Eventually, these components migrate to the surface of clean polymers. It is therefore recommended to print or bond to the material soon after treatment. However, once the treated surface has been interfaced with a coating, ink, adhesive, or another material, the bond becomes permanent. Applicati...
Solvent bonding actually chemically melts part of the acrylic which then re-hardens when the new piece is joined to it. This creates a very solid permanent bond; however, where the solvent touches will also create a permanent “stain” or “etch”. Similar to if you accidentally spread super...
The magnets are designed to be bolted to the various HydraMats to prevent unwanted movement of the mat inside of steel fuel tanks or fuel cells. If you are using an aluminum or polyurethane fuel cell, the magnets obviously won’t work. Holley offers click bond fasteners that are specially ...
3.Teflon (PTFE) In this type of PCB lamination, the process used mostly is the Chlorotrifluoroethylene (CTFE) thermoplastic film. A pressure of up to 200 psi is usually maintained throughout the duration of the lamination process. The heating process takes over after that. In this case, the...
or most oftendynesfor short. The surface energy of a given solid is a characteristic of its chemistry and surface topography. In the case of printed circuit boards and conformal coating, the surface that we are trying to wet-out and bond-to is usually thesolder maskor in some cases,compone...
Any material in space may be exposed to the aggressive oxidizer, atomic oxygen (AO). This is formed when oxygen reacts with UV radiation. The single atoms in oxygen bond with other oxygen molecules. In the Earth’s atmosphere the reaction is not sustained, but in space, the abundance of ...
x 2mm I.D. PTFE tube insert (cut from a length of stock I have, and I don’t plan on printing anything other than PLA with this particular printer – so no high temps). They very rarely ever have any clogging issues, and print just fine. This is also a moral dilemma of quality...
The polyimide and high-temperature bonding layer laminate optionally also contains a layer of unsintered, partially sintered, or totally sintered polytetrafluoroethylene (PTFE) bonded directly to the high-temperature bonding layer. In addition, the polyimide high-temperature bonding layer laminate may be...
PTFE prepregs exhibit very low loss and, when combined with PTFE circuit laminates, can provide very low loss performance in multilayer PCBs. If PTFE prepreg is used to assemble a multi-layer circuit, a PCB fabricator will be required to fuse to bond the layers together. However, the number...
