Here in this circuit LED is placed at the collector. i am with an impression that, IE=IB+IC. so it is better to keep at the emitter, right ? all the gain of the transistors are not utilized. What is the purpose of LED, placing at collector? Please e

You did not attach anything here. Transistor can be connected in different circuit(like common Emitter) and will use Collector current as output. Also Ic is about the same as Ie in value, as base current Ib is insignificant usually in uA.

Does the file come off of an ICT. Next question is it an AGinet/HP/Keysight 3070. If so you have a chance at finding out the format. It is probably posted online in the Keysight manual downloads section. I might still have an old paper copy of this

I need to extract data from a log file and sort the data in an Excel file. Details are as follows: - Log File is a measurement result produced by an In-Circuit Tester (no info. about it, no name, no type, nothing). - Measurement Result is from

Very interested what kind of profiler you use to check your profiles? KIC and Datapaqs have some predictors when it comes to reflow ovens or wave machines.

Hi Sir, The VP Machine that i am currently using takes reference from its own temperature sensor. so most of the time i would have to adjust multiple times for my PCB to soak at the right temperature or reflow for the duration that i need it to. Fo

I have never used a VP oven, but I did get a pretty good demo of one and was pushing hard for my company to acquire one. The issue ended up being that there was not an East Coast distributor for the "juice" and that became cost prohibitive to get sh

Hi All, Appreciate any inputs that may be given. Currently i am operating VP6000 Vapour Phase Reflow Oven from ASSCON. Over the last 2 years, we have around 100 different Recipes for many different PCBs. Each recipe is adjusted(6 Different Paramete

This person needs to have the "mental faculties" and a basic understanding of science, and understand concepts like flux, solder paste, time vs. temperature curves, etc. Do they have to be a metallurgist?? Of course not, but at the minimum they hav
