First, the product code: Q / YS.401 (Yi Shun brand)

Second, product characteristics:

This product is a single liquid type, non-peroxide, non-fluorine-free non-complexing agent efficient anti-tin, lead solution for tin plating, tin-lead alloy coating and solder joints removed. Particularly suitable for electronic components (IC), circuit board (PCB) manufacturing process of copper surface tin, pewter layer of the retreat, can be immersed or mechanical spray method of operation. Applicable to the copper surface of tin, pewter alloy layer of the withdrawal.

The substrate of copper (Cu) and nickel (Ni) matrix without any damage, and to remove copper rust copper substrate as bright as the new, the primary resin and plastic and ink words are not corrosive.

The amount of product withdrawal tin large, tin withdrawal speed fast, the use of lasting effective.

Fluoride-free, peroxide, smoke-free, odorless, environmentally friendly and easy to handle.
