I am trying to understand amplifier gain in transistor

Electronics Forum | Wed Jul 22 16:04:52 EDT 2020 | jordanabshire

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.

Don't understand the test results of an In-Circuit Tester

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

Don't understand the test results of an In-Circuit Tester

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

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

Hello Pete, Thanks for your insight. I understand and appreciate the NDA situation. I now have a good understanding of the process requirements thanks to you and Dave. Take care and keep in touch. Warm Regards, Francis Khoo.

Electroform stencil cost vs. value again other methods

Electronics Forum | Mon Nov 18 16:16:59 EST 2002 | Dick Van Belzen

We are trying to understand if there are proceeding or whitepapers which document the cost differential of the electroforming process for stencil vs. other methods. And what the related benefits are. Our center for advanced technology is trying to

Dielectric values of materials

Hi I don't understand your question. I do understand dielectrics and flex. What is "dielectric resistance". I might know it by a different name. YiEngr, MA/NY DDave

Wave Soldering to ENIG Pads

Without understanding machine loading, we'd guess that your current "every 30 wave solder day" sampling schedule is fairly conservative. Consider approaches to better understand change in the analysis results.
