TopLine offers a wide range solder columns to meet your needs. Typical solder core materials include Pb90/Sn10 , Pb80/Sn20, Indium and Lead Free. We offer copper ribbon and braided copper around the columns to increase reliability. After winding, the column is coated with solder. We can provide columns with a variety of diameters and lengths. A choice of different solder cores and copper thicknesses are available. Solder core materials from 0.20~0.89mm (8~35mils) are readily available. We can provide custom size columns to meet your project requirements. The tables below are just a small example of the column sizes we offer. Contact TopLine to discuss your specific needs.
