zener diode polarity

Electronics Forum | Sun Apr 25 08:06:47 EDT 2021 | pradeep14

Presently we are facing wrong loading of zener diode components in SMT Line. * In the particular product, we have two different part numbers of zener diode but the package and color code is same.Only the voltage is different is there in between two p

I've had the most success in a check/double-check set up. Most people will tell you that it's labor intensive, and they're not wrong. However, I suspect that those people have never had to manually change two components on a thousand boards at a sh

Protecting PCB, multiplexers and MCU in vending machines

Hello everyone, I am working on a very low cost, small and basic vending machine ($300) with wooden cabinet for small neighborhood stores. As you may know, it is necessary to properly protect the components to prevent users from trying to steal money

Hi Robert, Try looking at www.marsport.demon.co.uk/smd/ This site contains a list of html files with all marking codes known at this moment. Your example of a transistor with marking code 8A can be a 3V3 zener diode or a npn general purpose transi

The list is not yet completed but I picked few different component that our supplier are not able to get in Lead-Free or problem to get leadtime: Mfg Part : Zener Diodes BZG03 - MFG : Phillips Mfg Part : PME271Y447M - MFG: Evox-Rifa Mfg Part : LMC606

On average there are about 3 parts per board that get hand placed (x24 is 72 parts per panel). One of these parts is a big 1W resistor that cannot fit on our axial machine. We also have a Zener Diode that needs to be hand placed because its leads are

A couple of things i would try: 1. Does function 30 give you a nozzle height that is repeatable. The number should be around 200.....+/- 20 or so. 2. I would change the z-rod because the spring could be worn out and when the vacuum turns on....it ca

We run our process like that all the time paste then glue we use same profile as if we were just reflowing paste once in a while we have A plastic bodied part that has that problem we asume it was some mold relase still on the part basicly comtamena
