90g Tin Plating Powder450g Tin Plating Powder
Size90g makes 1lt
Size450g makes 5lt
Once the powder has been dissolved at 50C and allowed to cool it will plate copper
boards with a thin layer of tin. The solution is such that it will plate tin on tin and so by leaving a board in the solution longer, a thicker layer is built up. 0.2 micron after 20 seconds, 0.8 - 10 micron after 5 min etc. A tin plated circuit protects the board from oxidisation and greatly improves solderability. Working solution has a shelf life of 6 months, unmixed powder has an unlimited shelf life. Supplied in two pack sizes: 90g which comes in a plastic container to store the solution when mixed, and 450g.
