Yes, titanium solder masks from EUTECT can be reconditioned to such an extent that they regain their original precision and process stability after repair. As titanium masks in the mini wave soldering process are exposed to high thermal, chemical and mechanical stresses, regular rework is crucial to ensure the soldering quality in the long term.
EUTECT carries out a structured, multi-stage process for this. After disassembly, the first step is gentle pre-cleaning, during which flux residues, oxidation and tin deposits are completely removed without attacking the titanium. The surface is then prepared in a controlled manner so that oxide layers are removed and functional surfaces are restored to a process-stable condition without impairing the geometric precision of the mask.
This is followed by a detailed inspection of all critical areas such as webs, fixing points or baffle walls, during which flatness, parallelism and dimensional accuracy are checked. The mask is then specifically heat-treated to stabilise the microstructural properties of the titanium and ensure that it remains dimensionally stable even with frequent temperature changes. Even fine structures retain their shape in the long term as a result.
Finally, each reworked titanium solder mask is tested under real process conditions and only released for series production if it functions perfectly. Reconditioning significantly extends the service life of the masks, reduces the need for new production and ensures consistently high process quality. At the same time, it makes an important contribution to resource conservation and sustainable production.
