Titanium soldering mask allows complex selective soldering
“In selective soldering or respectively soldering using miniwave and mask technique, the customer can only achieve true process stability and benefits if the solder nozzle was designed and manufactured in relation to the mask and, as a result, their joint function is ensured,” explains Matthias Fehrenbach, Managing Director of Eutect GmbH. Increasingly complex components – be it due to miniaturization or due to difficult to access and sensitive geometries – require new solutions.
For example, if printed circuit boards are already installed in housings, lower-side SMD components are arranged very close to the housing and the THT solder joints to be soldered, the walls, spacer webs and connections must be very thin. Nevertheless, the metal webs must be stable in the long term. Titanium is a reliable material, especially for web widths of far less than 1 mm. Its high strength permits the manufacture of web widths of less than 0.5. The metal is very durable and resistant to flux, aggressive cleaning substrates and other chemical influencing factors.
What’s more, if components or connectors must be aligned or secured, the company provides the mask with specific catch geometries or fixation systems so that all components stay in the desired position. The mask geometry, hold-down devices, alignment elements and sliders are defined during the evaluation and project development. In the process, the fixation system comprising spring and latching elements guarantees a high functionality. Effortless loading and unloading of the masks is also ensured. All masks from Eutect are produced in the company’s in-house CNC production.
