Calibration of numerical model of magnetic induction brazing

A method of finding the temperature dependences of physical parameters of metals is proposed and discussed. The method is based on the combination of measurement of the surface temperature of the material and subsequent solution of the inverse problem using the multi-parametric optimiza...

Alternative technology for SMD components connection by non‑conductive adhesive on a flexible substrate

This article deals with the assembly of SMD chip components onto a flexible substrate by using non-conductive adhesives. In the experiments, two electrically conductive adhesives (ECA) and two non-conductive adhesives (NCA) were used. The verification of the properties and usability of NCAs&...

Wide range humidity sensors printed on biocomposite films of cellulose nanofibril and poly(ethylene glycol)

Cellulose nanofibril (CNF) films were prepared from side streams generated by the sugarcane industry, that is, bagasse. Two fractionation processes were utilized for comparison purposes: (1) soda and (2) hot water and soda pretreatments. 2,2,6,6‐Tetramethylpiperidinyl‐1‐oxyl‐mediated oxidation was applied ...
