Effect of soldering techniques and gap distance on tensile strength of soldered Ni-Cr alloy joint

PURPOSE The present study was intended to evaluate the effect of soldering techniques with infrared ray and gas torch under different gap distances (0.3 mm and 0.5 mm) on the tensile strength and surface porosity formation in Ni-Cr base metal alloy. MATERIALS AND METHODS Thirty five dumbbell shaped Ni-Cr alloy specimens were prepared and assigned to 5 groups according to the soldering method ...

Evaluation of Soldered Joints of Two Base Metal Ceramic Alloys: Supercast and Minalux

Background: Different soldering techniques have a variety of applications in dentistry. One of the most important uses of soldering is to join multiple-unit fixed partial dentures together. In this Study, two base metal alloys (Supercast and Minalux) were soldered  and their tensile, compressive and flexural strengths were measured and compared to each other. Materials and methods: In this ...

Effects of reflow profile and thermal conditioning on intermetallic compound thickness for SnAgCu soldered joints

Purpose – The purpose of this paper is to investigate the effects of reflow time, reflow peak temperature, thermal shock and thermal aging on the intermetallic compound (IMC) thickness for Sn3.0Ag0.5Cu (SAC305) soldered joints. Design/methodology/approach – A four-factor factorial design with three replications is selected in the experiment. The input variables are the peak temperature, the dur...
