  • Patent number: 6083848
    Abstract: A method for removing solder from the leads of ICs including immersing the IC in an acid solution. The acid solution dissolves the excess solder on the IC leads. The acid solution is preferably a hydrogen chloride solution containing about 38% hydrogen chloride and 62% water. The acid solution, however, can contain up to 50% hydrogen chloride. After the IC is immersed for a period of time, preferably ten minutes, it is removed from the acid solution and rinsed with water. The IC is rinsed so as to remove any remaining acid solution residue. Rinsing for 5 minutes or more typically ensures removing all of the acid solution. The IC is then inspected to determine whether substantially all of the excess solder is removed from the IC leads. If excess solder still remains on the IC leads, the IC is reintroduced into the solder removing process including immersing the IC in the acid solution, rinsing the IC with water, and inspecting the IC.
