The surfaces of printed circuit boards play an important role in the wettability of the connection surfaces during the soldering process. In addition, chemical surfaces protect the copper from oxidation, thus extending the shelf life of the printed circuit boards. We offer you a selection of surfaces, including lead-free HAL, chemical tin, chemical gold, and chemical silver (upon request).
To assist you in choosing the appropriate surface for your PCB we would like to introduce you to the advantages and disadvantages of the various coatings. Please note that the choice of surface depends on the particular application and specific requirements. We are happy to advise you to find the optimal surface for your purposes.
