I am having problems with SMT electrolytic capacitors expanding and changing values after going through our reflow. The reflow profile we use includes temperatures of 200 deg C for 60 seconds and 230 deg C for 30 seconds. We need to use this profil

Hello We use a 5 zone conceptronics HVN70 and never before have we had something we could not do including 6 layers Rohs complicated boards. Recently we had a larger - simple 2 layer board - all 1206's etc however there are 15 pcs of a LARGE high m

Soldering electronic components like electrolytic capacitors can be some of the most difficult terms in PCB repair. Electrolytic capacitors, like other components, come in two main formats. 1. Through-hole capacitors have long leads designed to pass

We are building a plasma diagnostic to monitor MHD phenomena in tokamak. As part of the development, we need high-voltage, high-power RF capacitors to tune and match an inductive load. This application is similar to a small induction heater, with t

Our solder irons are tuned to 700*F, but the in-use temperature varies according to the solder alloy and the characteristics of the board and components. Check some of the papers on multilayer ceramic capacitors. They get fairly specific, for insta
