The Surface Treatment Of Push-in Terminals Is Shifting Towards Lead-free Plating.

As a common component in modern electrical connection systems, the surface plating of the metal parts of push in type terminal block is gradually transitioning from traditional lead-containing alloys to lead-free solutions. This shift responds to regional restrictions on hazardous substances and also reflects the shared trend in the push in terminal block wire connector industry towards reducing lead pollution.

In the design and manufacturing process of push connector block, the choice of lead-free coating not only affects the appearance of the finished product, but also relates to the manufacturability of the soldering and assembly stages. Unlike tin-lead alloy plating, modern lead-free surface treatments typically employ pure tin or combinations of other metals to meet the growing market demand for lead-free products.
