The demands on electronics production to become more flexible have been growing since well before Industry 4.0 – the Scheugenpflug Lean Thinking approach is the solution. Lean Thinking keeps enterprises strong and competitive In order to remain competitive, flexibility, globalisation and economic efficiency have been in the focus of attention since well before the "Internet of Things" and its predicted effects on electronics suppliers. Already today, electronics manufacturers must be able to react quickly and without much effort to changed production requirements. The Scheugenpflug system of...

Process Engineering Efficient metering and dispensing – a matter of the right processing technology Efficient potting, filling and gluing are key to ensuring the functionality of electronic products. It is essential to consider process engineering technology in its entirety, because dispensing quality not only depends on the machine used for metering and dispensing. Other influencing factors, such as the casting resin properties, storage conditions, the design and shape of the substrate, and the curing method play an essential role. On the following pages you will find the essence of what there...

Process Engineering Process Engineering Which Casting Resin can be Used for What Purpose? Casting Resins and Process Parameters to be Considered Casting resins used today in the production of electronic components are synthetic resins manufactured from different materials, such as epoxy, polyurethane or silicone. The resins processed for metering and dispensing may have liquid to paste-like consistency. Their solidification is the result of a chemical reaction (cross-linking), which may be triggered by one of the following influencing factors, such as heat, moisture, UV light, mixing with a hardener,...

Process Engineering Process Engineering Shear Thinning Fluids Shear Thickening Fluids Thixotropic Fluids Fillers Optimise Resin Properties When Selected With Great Care tSch dw = plate distance tSch = shear time For non-Newtonian fluids (e.g. toothpaste) their viscosity depends not only on temperature and pressure, but also on the velocity gradient. Their viscosity is sometimes also referred to as structural viscosity or apparent viscosity. It is difficult to specify their viscosity precisely. Deviating behaviour of liquids from Newton’s law are flow characteristics with flow limitations, such...

Process Engineering Process Engineering Trapped air bubbles rise easier from a material film which is thin. Additional heating at an appropriate level also lowers a material’s viscosity and accelerates the degassing process. Furthermore, all fittings, material feed lines, pumps and valves must be sealed air-tight or otherwise made vacuum-proof. This is the only way to prevent air from re-entering into the material during reloading from the drum, barrel or cartridge. Moisture – Some resin systems cure with moisture. To trigger a reaction, all it takes is to expose the dispensing medium to the...

Process Engineering Process Engineering Static or Dynamic Mixing? When the decision is made in favour of a 2C casting resin, the natural next question is how to mix the two components. Dynamic mixing meters the two components and then blends them, each with the appropriate quantity to receive the correct mixing ratio, in a chamber where they are mixed by an agitator. The two separate components are blended and thoroughly mixed at the appropriate speed of the agitator. In this case, the components do not get in contact with one another, i.e. they cannot react, before they reach the mixing chamber....
