Solder washers are commonly used for cable assembly, connector pin and through-hole applications.

  • The inside diameter or ID is the most important dimension of the solder washer. If it is too small it will not fit over the intended pin. When the application calls for the solder washer to be flux coated, please be aware that the ID will be smaller than the specified ID dimension. You must compensate for the added flux material.
  • Solder washers are referred to by the following: Outside diameter (OD) x Inside Diameter (ID) x Thickness (T)
  • There may be some instances when the washer may be too small to be flux coated. If that is the case, Array Solders can also fabricate washers with internal flux. Internal flux percentages can range from 1-3%.
  • When you are using a flux coated solder washer, less is more. In other words, 0.5% to 1.5% flux by weight is more than enough to reduce the surface oxides and prepare the surface for wetting.
  • The thickness will determine the solder volume. Our engineers will work with you to determine the best inside and outside dimensions for your application.
