Abstract

PCB (printed circuit board) is a copper-coated board that is a container for electronic components arranged to form electronic circuits. Copper surfaces that are easy to oxidize (corrosion) need to be soothed with a layer of Sn (tin). Based on the TFME study case, the electroplating technique requires more cost for tin plating. The immersion process of the tin plating model is superior in terms of cost and quality. To determine the right combination parameters so as to obtain a thickness that is in accordance with the IPC-4554 standard, namely a minimum of 1000 nm, the research method used is Design of Experiments (DoE). There are nine experimental combinations of the DoE results. Combination parameter testing is done using a SEM (scanning electron microscope) machine. The combination of four to nine has met IPC standards with a thickness of between 1040-1540 nm. The correct parameter is obtained by the combination of 5 with the parameter temperature of 700 and time of 60 minutes, and the result is an average thickness of 1.2 µm and has an uncertain value of the measurement is 7.

Abstract

A pressure vessel is a container designed to hold fluids under pressure, including liquids and gases with varying pressures and temperatures. The pressure exerted on the vessel's walls and body is a critical factor that must be carefully considered to ensure compliance with applicable international design standards and prioritize worker safety and security. This research focused on a pressure vessel to investigate the impact of temperature on shell thickness to meet ASME standards. The study utilized shell components made from SA-516 Gr 70 and SA-537 materials. Experiments were conducted with each material at temperatures of 250°C, 235°C, and 343°C, revealing that thickness varies based on material and temperature. The research findings demonstrate compliance with ASME standards, as the shell thickness in all trials exceeded the minimum specified in the drawings.
