Abstract
Abstract A heat sink and holding device for use in soldering a plurality of electrical leads. The complete array of electrical leads is connected to a common heat sink which also holds all of the leads while each lead is soldered individually. The device comprises two spring clips of high heat conductive material connected to a base of heavy material and having a nonskid bottom. One of the spring clips comes in contact with each wire lead and acts as the main heat sink portion. The other spring clip acts primarily as a holder.
