Air entrapment, extended cycle times, thermal hotspots and time-consuming rework: many problems in electronics manufacturing are not caused by the design of the assembly itself, but by compromises made when selecting the potting compound. EPOXONIC GmbH therefore takes a different approach, developing customized reactive resin systems that are precisely tailored to the application and manufacturing process, without unnecessary compromises.

In practice, standard materials often create conflicting requirements. Higher thermal conductivity, for example, can impair dispensing characteristics; a longer pot life can increase processing times; and particularly high mechanical strength can make repairs more difficult. These compromises add up throughout the entire value chain.

Given the intense international competition in the electronics industry, many manufacturers can no longer afford such trade-offs. This applies not only to manufacturing results, but also to the overall course of a project. Many electronics manufacturers are familiar with the following scenario: a material performs well in the laboratory but causes difficulties once it reaches series production. Excessive viscosity makes void-free potting more difficult, while unsuitable curing profiles increase cycle times or lead to internal stresses. Processes are often adapted, additional production steps introduced or quality limitations accepted, not because they are technically unavoidable, but because the material itself does not allow for a better solution.

This becomes particularly apparent in power electronics, high-voltage applications, sensor technology and electromobility, where thermal, electrical and mechanical requirements must be met simultaneously. A compromise in any one of these properties can affect the reliability of the entire assembly.

EPOXONIC therefore develops its potting compounds consistently around the specific application and the subsequent manufacturing process. From the early stages of development, the company considers not only the required material properties, but also viscosity, mixing ratio, pot life, deaeration behavior, curing profile and the requirements of existing dispensing and production equipment.

The objective is not to find the best possible compromise, but to eliminate the need for compromises in the first place. The material should adapt optimally to the product and its manufacturing process, rather than the other way around. To achieve this, EPOXONIC supports its customers throughout the entire process, from defining the initial requirements and laboratory development to dispensing trials and successful series production. Close cooperation with production teams and equipment manufacturers makes it possible to identify and eliminate potential problems before production begins.

Customized potting compounds therefore do more than improve the functional reliability and service life of electronic assemblies. They also stabilize manufacturing processes, reduce scrap and rework, shorten cycle times and minimize the risk of complaints. The result is more cost-effective production and greater process reliability, without the typical trade-offs associated with standard materials.
