Coating, encapsulation, or potting – which is right for protecting your electronics? In this JoinedUpMinute, Ian explains the key differences between three common protection methods: Coating (aka conformal coating) — a thin protective film over a PCB assembly Encapsulation (sometimes called ‘glob topping’) — a thicker layer over specific areas Potting — filling an enclosure […]

I saw a newsletter article which said that fluorescent animals are much more common than previously thought. Researchers who studied 125 mammal species, including cats, bats, polar bears and wombats (pictured), found that all of them showed some form of fluorescence, and that 86% had fur which actually glowed under UV light. This picture is […]

Dymax 9771 Dual-Cure Light and Moisture-Cure Conformal Coating is now available. This low outgassing material is the first conformal coating that meets ASTM E595 and MIL-STD 883 and is therefore suitable for the aerospace and defence markets in applications including missile, satellite, and space critical printed circuit board assemblies. This coating has UL 94 V-0 […]

Simple application, fast cure, no solvents – these are the features many pcb assemblers are looking for when specifying a printed circuit board conformal coating. You want good protection of your pcb assemblies with efficient process and high throughput. If this is you, then Dymax’s Light-Curable Conformal Coatings Selector Guide should be on your reading […]

Dymax 9452-FC is an advanced low viscosity conformal coating for printed circuit boards, formulated with a revolutionary new technology as an alternative to thin, solvent-based conformal coatings. Whilst it has a very low viscosity – 20 cP – it still provides good electrical insulation and protection against humidity, plus very good thermal shock and corrosion resistance. It offers […]

The Problem A leading industrial electronics company was developing a new industrial inverter model that required a high cured thickness of conformal coating to meet electric performance. The product they were using at the time was a solvent-based coating with a low cured thickness. Air pollution and odours from solvent based coatings were  a concern for […]

Dymax Speedmask® 9-20479-B-Rev-A UV/light cure temporary masking agent is specifically designed to meet the needs of the electronics industry, where its fast cure and simple removal will improve productivity in printed circuit board assembly.  It is formulated for the protection of pcb connectors and other components, either during the soldering process, or during conformal coating. […]

We are delighted to offer a Technical Guide to Light-Cure Conformal Coatings for printed circuit boards, authored by Dymax. These coatings provide superior protective performance with the added benefit of UV/light cure for quick, convenient processing and cost saving. The guide enables customers to better understand the production savings possible from light curing. It discusses the choice […]

Dymax Dual-Cure 9482 is a UV light and moisture-cure conformal coating specially formulated to flow underneath components on printed circuit boards and cure in these shadowed areas by using ambient moisture, which can result in faster throughput for through hole assemblies. Dymax 9482 coating demonstrates excellent re-workability which is of particular importance to manufacturers of expensive pcb’s or manufacturers looking […]

We have previously discussed the need for greater precision and repeatability of adhesive dispensing within ever smaller and denser pcb real estate in the world of electronics assembly and manufacturing. Applications include optical bonding (e.g. touch screens, displays, smartphones, tablets), conformal coating, encapsulation (either dam & fill or glob top), underfills, and the like. There […]

We are re-launching our self-adhesive tapes for masking during the conformal coating process. INT 630 Conformal Coating Masking Tape is a polyester film based tape with a silicone-free synthetic resin adhesive, and a conductive adhesive layer designed to reduce static discharge upon application and removal. Most users prefer silicone-free adhesives for this masking procedure, as […]

With the combination of expertise in LED light curing equipment technology and adhesive formulation, our partners DYMAX have an ever-growing list of adhesive and coating formulations optimised to cure with our BlueWave LED curing lamps. These include applications in electronics, glass bonding, plastic bonding, temporary masking, structural bonding and medical device manufacturing.
