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 a lot of points skilled by a particular consumer of floor modifier supplies. The product has been acquired significantly properly and has now been awarded UL94V-0 approval, additional advancing the proposition.
The consumer in query, a big producer of energy distribution electronics, initially expressed an curiosity in Electrolube’s floor modifier supplies attributable to longstanding and unresolved points referring to coating protection and connectivity. Their rationale for utilizing a floor modifier coating versus a traditional conformal coating was appropriate as the mixture of required coating thickness (2µm) and really low movie power (abrasion resistance) can facilitate big processing advantages. Customers of floor modifier coatings can fully 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 consumer complained nonetheless, 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 consumer couldn’t be assured within the integrity of protection.
With many variations of board form and design, in addition to quite a few totally different connector codecs, a contemporary method and coating materials was required. Electrolube accepted the problem to develop a cheap materials that may 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 assessments, together with extremely stringent salt mist, humidity and blended corrosive fuel testing; all assessments have been handed efficiently. In depth connectivity testing confirmed noticeable enhancements when in comparison with earlier outcomes skilled by the consumer, whereas the inclusion of a UV hint meant the boards have been now far simpler to examine for protection. General, the brand new FPC coating has resulted in a major value saving.
The enhancements in efficiency, inspection and price of Electrolube’s FPC coating, in contrast with beforehand used materials and the outcomes of machine trials at numerous firms to verify compatibility, meant the corporate was in a position to merely swap over to FPC as a drop-in substitute.
Robert Crosby-Clarke, Director of Strategic Advertising and marketing of Electrolube, feedback: “The partnership between ourselves and the shopper’s engineering group is a primary instance of Electrolube’s devoted method to fixing issues. With a robust emphasis on each analysis and collaboration, we’re frequently growing new merchandise, such because the FPC coating, and all the time go the additional mile – not simply to make sure that the product is correct for the job, however to advise and assist our clients select the most secure, most acceptable and economical technique of software.”
