Abstract: The arrangement which is designed to be put into an electrolytic vat comprises a framework arranged to receive several pairs of substrates placed back-to-back, mechanical systems fixed to the framework for positioning and maintaining the substrates in place on the framework and an electrical system likewise fixed to the framework and having contact points to enable coupling the conductive layers of the integrated circuits onto which the conductive material is to be deposited to the feed voltage source of the vat.Preferably the mechanical systems are designed to maintain the two substrates of each pair in contact one against the other.

Abstract: This invention concerns a method of suspending electrical components such as piezoelectric resonators, as well as the suspension members themselves. An electrically conductive lead is provided with at least one protuberance in the form of a hollow cone transverse to the length thereof. The end of the cone is pierced or cut off and the cone is provided with a soldering alloy. The conductive lead is placed adjacent the component so that the tip of the cone is in contact with the surface of the component at a desired location and heat is applied so that the solder fuses and flows through the tip by capillary action thereby effecting a soldered joint.
