MacDermid Alpha Electronics Options, a world provider of built-in options from Circuitry, Meeting and Semiconductors, offering unmatched capabilities in electronics design and manufacturing, is proud to announce that their Electrolube model has formulated a Conformal Coating FPC. This conformal coating is designed to resolve numerous points skilled by a particular person of floor modifier supplies. The product has been acquired significantly nicely and has now been awarded UL94V-0 approval, additional advancing the proposition.
The person in query, a big producer of energy distribution electronics, initially expressed an curiosity in Electrolube’s floor modifier supplies because of longstanding and unresolved points regarding coating protection and connectivity. Their rationale for utilizing a floor modifier coating versus a standard conformal coating was appropriate as the mixture of required coating thickness (2µm) and really low movie energy (abrasion resistance) can facilitate large processing advantages. Customers of floor modifier coatings can utterly coat a PCB and connectors with out masking as when the female and male contact surfaces are joined, the abrasion forces throughout insertion ought to cleanly take away the coating materials permitting electrical contact.
The person complained nevertheless, that their expertise with floor modifier supplies was fairly the reverse; the fabric wouldn’t rub off cleanly throughout insertion creating a further checking and re-testing course of. Inspection of the coating protection was additionally very troublesome because of the lack of UV hint and the person couldn’t be assured within the integrity of protection.
With many variations of board form and design, in addition to quite a few completely different connector codecs, a recent method and coating materials was required. Electrolube accepted the problem to develop a cheap materials that might additionally resolve all of the technical points with connectivity and inspection being skilled.
The brand new, non-flammable fluorinated polymer coating – FPC, was developed and underwent a collection of buyer exams, together with extremely stringent salt mist, humidity and blended corrosive gasoline testing; all exams had been handed efficiently. Intensive connectivity testing confirmed noticeable enhancements when in comparison with earlier outcomes skilled by the person, whereas the inclusion of a UV hint meant the boards had been now far simpler to examine for protection. Total, the brand new FPC coating has resulted in a major price saving.
The enhancements in efficiency, inspection and value of Electrolube’s FPC coating, in contrast with beforehand used materials and the outcomes of machine trials at varied firms to verify compatibility, meant the corporate was in a position to merely change over to FPC as a drop-in alternative.
Robert Crosby-Clarke, Director of Strategic Advertising of Electrolube, feedback: “The partnership between ourselves and the client’s engineering staff is a main instance of Electrolube’s devoted method to fixing issues. With a robust emphasis on each analysis and collaboration, we’re regularly creating new merchandise, such because the FPC coating, and at all times go the additional mile – not simply to make sure that the product is true for the job, however to advise and assist our prospects select the most secure, most acceptable and economical methodology of utility.”
